Parameters:

connection - java.sql.Connection a JDBC-conn to be used for obtaining a "real statement"

sql - java.lang.String thw sql to execute

Throws:

java.sql.SQLException - if a PreparedStatement cannot be created using the supplied conn and sql

LoggablePreparedStatement

public LoggablePreparedStatement(java.sql.Connection connection,
                                 java.lang.String sql,
                                 int resultType,

                          throws java.sql.SQLException

Throws:

java.sql.SQLException

Method Detail

addBatch

public void addBatch()
              throws java.sql.SQLException

JDBC 2.0 Adds a set of parameters to the batch.

Specified by:

addBatch in interface java.sql.PreparedStatement

Throws:

java.sql.SQLException - if a database access error occurs

See Also:

Statement.addBatch(java.lang.String)

addBatch

public void addBatch(java.lang.String sql)
              throws java.sql.SQLException

JDBC 2.0 Adds a SQL command to the current batch of commands for the statement. This method is optional.

Specified by:

addBatch in interface java.sql.Statement

Parameters:

sql - typically this is a static SQL INSERT or UPDATE statement

Throws:

java.sql.SQLException - if a database access error occurs, or the driver does not support batch statements

cancel

public void cancel()
            throws java.sql.SQLException

Cancels this Statement object if both the DBMS and driver support aborting an SQL statement. This method can be used by one thread to cancel a statement that is being executed by another thread.

Specified by:

cancel in interface java.sql.Statement

Throws:

java.sql.SQLException - if a database access error occurs

clearBatch

public void clearBatch()
                throws java.sql.SQLException

JDBC 2.0 Makes the set of commands in the current batch empty. This method is optional.

Specified by:

clearBatch in interface java.sql.Statement

Throws:

java.sql.SQLException - if a database access error occurs or the driver does not support batch statements

clearParameters

public void clearParameters()
                     throws java.sql.SQLException

Clears the current parameter values immediately.

In general, parameter values remain in force for repeated use of a Statement. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values; this can be done by calling clearParameters.

Specified by:

clearParameters in interface java.sql.PreparedStatement

Throws:

java.sql.SQLException - if a database access error occurs

clearWarnings

public void clearWarnings()
                   throws java.sql.SQLException

Clears all the warnings reported on this Statement object. After a call to this method, the method getWarnings will return null until a new warning is reported for this Statement.

Specified by:

clearWarnings in interface java.sql.Statement

Throws:

java.sql.SQLException - if a database access error occurs

close

public void close()
           throws java.sql.SQLException

Releases this Statement object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed. It is generally good practice to release resources as soon as you are finished with them to avoid tying up database resources.

Note: A Statement is automatically closed when it is garbage collected. When a Statement is closed, its current ResultSet, if one exists, is also closed.

Specified by:

close in interface java.sql.Statement

Throws:

java.sql.SQLException - if a database access error occurs

execute

public boolean execute()
                throws java.sql.SQLException

Executes any kind of SQL statement. Some prepared statements return multiple results; the execute method handles these complex statements as well as the simpler form of statements handled by executeQuery and executeUpdate.

Specified by:

execute in interface java.sql.PreparedStatement

Throws:

java.sql.SQLException - if a database access error occurs

See Also:

Statement.execute(java.lang.String)

execute

public boolean execute(java.lang.String sql)
                throws java.sql.SQLException

Executes a SQL statement that may return multiple results. Under some (uncommon) situations a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this unless you are (1) executing a stored procedure that you know may return multiple results or (2) you are dynamically executing an unknown SQL string. The methods execute, getMoreResults, getResultSet, and getUpdateCount let you navigate through multiple results. The execute method executes a SQL statement and indicates the form of the first result. You can then use getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s).

Specified by:

execute in interface java.sql.Statement

Parameters:

sql - any SQL statement

Returns:

true if the next result is a ResultSet; false if it is an update count or there are no more results

Throws:

java.sql.SQLException - if a database access error occurs

setCharacterStream

public void setCharacterStream(int parameterIndex,
                               java.io.Reader reader,
                               int length)
                        throws java.sql.SQLException

JDBC 2.0 Sets the designated parameter to the given Reader object, which is the given number of characters long. When a very large UNICODE value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.Reader. JDBC will read the data from the stream as needed, until it reaches end-of-file. The JDBC driver will do any necessary conversion from UNICODE to the database char format.

Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.

Specified by:

setCharacterStream in interface java.sql.PreparedStatement

Parameters:

parameterIndex - the first parameter is 1, the second is 2, ...

reader - the java reader which contains the UNICODE data

length - the number of characters in the stream

Throws:

java.sql.SQLException - if a database access error occurs

setClob

public void setClob(int i,
                    java.sql.Clob x)
             throws java.sql.SQLException

JDBC 2.0 Sets a CLOB parameter.

Specified by:

setClob in interface java.sql.PreparedStatement

Parameters:

i - the first parameter is 1, the second is 2, ...

x - an object representing a CLOB

Throws:

java.sql.SQLException - if a database access error occurs

setCursorName

public void setCursorName(java.lang.String name)
                   throws java.sql.SQLException

Defines the SQL cursor name that will be used by subsequent Statement execute methods. This name can then be used in SQL positioned update/delete statements to identify the current row in the ResultSet generated by this statement. If the database doesn't support positioned update/delete, this method is a noop. To insure that a cursor has the proper isolation level to support updates, the cursor's SELECT statement should be of the form 'select for update ...'. If the 'for update' phrase is omitted, positioned updates may fail.

Note: By definition, positioned update/delete execution must be done by a different Statement than the one which generated the ResultSet being used for positioning. Also, cursor names must be unique within a conn.

Specified by:

setCursorName in interface java.sql.Statement

Parameters:

name - the new cursor name, which must be unique within a conn

Throws:

java.sql.SQLException - if a database access error occurs

                    java.sql.Date x,
                    java.util.Calendar cal)
             throws java.sql.SQLException

JDBC 2.0 Sets the designated parameter to a java.sql.Date value, using the given Calendar object. The driver uses the Calendar object to construct an SQL DATE, which the driver then sends to the database. With a a Calendar object, the driver can calculate the date taking into account a custom timezone and locale. If no Calendar object is specified, the driver uses the default timezone and locale.

Specified by:

setDate in interface java.sql.PreparedStatement

Parameters:

parameterIndex - the first parameter is 1, the second is 2, ...

x - the parameter value

cal - the Calendar object the driver will use to construct the date

Throws:

Throws:

java.sql.SQLException - if a database access error occurs

setEscapeProcessing

public void setEscapeProcessing(boolean enable)
                         throws java.sql.SQLException

Sets escape processing on or off. If escape scanning is on (the default), the driver will do escape substitution before sending the SQL to the database. Note: Since prepared statements have usually been parsed prior to making this call, disabling escape processing for prepared statements will have no effect.

Specified by:

setEscapeProcessing in interface java.sql.Statement

Parameters:

enable - true to enable; false to disable

Throws:

java.sql.SQLException - if a database access error occurs

setFetchDirection

public void setFetchDirection(int direction)
                       throws java.sql.SQLException

JDBC 2.0 Gives the driver a hint as to the direction in which the rows in a result set will be processed. The hint applies only to result sets created using this Statement object. The default value is ResultSet.FETCH_FORWARD.

Note that this method sets the default fetch direction for result sets generated by this Statement object. Each result set has its own methods for getting and setting its own fetch direction.

Specified by:

setFetchDirection in interface java.sql.Statement

Parameters:

direction - the initial direction for processing rows

Throws:

java.sql.SQLException - if a database access error occurs or the given direction is not one of ResultSet.FETCH_FORWARD, ResultSet.FETCH_REVERSE, or ResultSet.FETCH_UNKNOWN

setFetchSize

public void setFetchSize(int rows)
                  throws java.sql.SQLException

JDBC 2.0 Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed. The number of rows specified affects only result sets created using this statement. If the value specified is zero, then the hint is ignored. The default value is zero.

Specified by:

setFetchSize in interface java.sql.Statement

Parameters:

rows - the number of rows to fetch

Throws:

java.sql.SQLException - if a database access error occurs, or the condition 0 <= rows <= this.getMaxRows() is not satisfied.

public void setInt(int parameterIndex,
                   int x)
            throws java.sql.SQLException

Sets the designated parameter to a Java int value. The driver converts this to an SQL INTEGER value when it sends it to the database.

Specified by:

This limit applies only to BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, and LONGVARCHAR fields. If the limit is exceeded, the excess data is silently discarded. For maximum portability, use values greater than 256.

Specified by:

setMaxFieldSize in interface java.sql.Statement

Parameters:

max - the new max column size limit; zero means unlimited

Throws:

java.sql.SQLException - if a database access error occurs

setMaxRows

public void setMaxRows(int max)
                throws java.sql.SQLException

Sets the limit for the maximum number of rows that any ResultSet can contain to the given number. If the limit is exceeded, the excess rows are silently dropped.

Throws:

java.sql.SQLException - if a database access error occurs

setNull

public void setNull(int parameterIndex,
                    int sqlType)
             throws java.sql.SQLException

Sets the designated parameter to SQL NULL.

Note: You must specify the parameter's SQL type.

Specified by:

                    java.lang.String typeName)
             throws java.sql.SQLException

JDBC 2.0 Sets the designated parameter to SQL NULL. This version of setNull should be used for user-named types and REF type parameters. Examples of user-named types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types.

Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-named type the name is the type name of the parameter itself. For a REF parameter the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-named and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-named or REF type, the given typeName is ignored.

Specified by:

setNull in interface java.sql.PreparedStatement

Parameters:

parameterIndex - the first parameter is 1, the second is 2, ...

sqlType - a value from java.sql.Types

typeName - the fully-qualified name of an SQL user-named type, ignored if the parameter is not a user-named type or REF

Throws:

java.sql.SQLException - if a database access error occurs

setObject

public void setObject(int parameterIndex,
                      java.lang.Object x)
               throws java.sql.SQLException

Sets the value of a parameter using an object; use the java.lang equivalent objects for integral values.

The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument java object will be converted to the corresponding SQL type before being sent to the database.

Note that this method may be used to pass datatabase- specific abstract data types, by using a Driver-specific Java type. If the object is of a class implementing SQLData, the JDBC driver should call its method writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, Struct, or Array, then the driver should pass it to the database as a value of the corresponding SQL type. This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of those interfaces.

Specified by:

setObject in interface java.sql.PreparedStatement

Parameters:

parameterIndex - the first parameter is 1, the second is 2, ...

x - the object containing the input parameter value

Throws:

java.sql.SQLException - if a database access error occurs

setObject

public void setObject(int parameterIndex,
                      java.lang.Object x,
                      int targetSqlType)
               throws java.sql.SQLException

Sets the value of the designated parameter with the given object. This method is like setObject above, except that it assumes a scale of zero.

Specified by:

setObject in interface java.sql.PreparedStatement

Parameters:

parameterIndex - the first parameter is 1, the second is 2, ...

x - the object containing the input parameter value

targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database

Throws:

java.sql.SQLException - if a database access error occurs

setObject

public void setObject(int parameterIndex,
                      java.lang.Object x,
                      int targetSqlType,
                      int scale)
               throws java.sql.SQLException

Sets the value of a parameter using an object. The second argument must be an object type; for integral values, the java.lang equivalent objects should be used.

The given Java object will be converted to the targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing SQLData), the JDBC driver should call its method writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type.

Note that this method may be used to pass database-specific abstract data types.

Specified by:

setObject in interface java.sql.PreparedStatement

Parameters:

parameterIndex - the first parameter is 1, the second is 2, ...

x - the object containing the input parameter value

targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.

scale - for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point. For all other types, this value will be ignored.

Throws:

java.sql.SQLException - if a database access error occurs

columnIndexes - an array of the indexes of the columns in the inserted row that should be made available for retrieval by a call to the method getGeneratedKeys

Returns:

true if the first result is a ResultSet object; false if it is an update count or there are no results

Throws:

java.sql.SQLException - if a database access error occurs or the elements in the int array passed to this method are not valid column indexes

executeUpdate

public int executeUpdate(java.lang.String sql,
                         java.lang.String[] columnNames)
                  throws java.sql.SQLException

Executes the given SQL statement and signals the driver that the auto-generated keys indicated in the given array should be made available for retrieval. The driver will ignore the array if the SQL statement is not an INSERT statement.

Specified by:

executeUpdate in interface java.sql.Statement

Parameters:

sql - an SQL INSERT, UPDATE or DELETE statement or an SQL statement that returns nothing

columnNames - an array of the names of the columns that should be returned from the inserted row

Returns:

either the row count for INSERT, UPDATE, or DELETE statements, or 0 for SQL statements that return nothing

Throws:

java.sql.SQLException - if a database access error occurs, the SQL statement returns a ResultSet object, or the second argument supplied to this method is not a String array whose elements are valid column names

Since:

1.4

execute

public boolean execute(java.lang.String sql,
                       java.lang.String[] columnNames)
                throws java.sql.SQLException

Executes the given SQL statement, which may return multiple results, and signals the driver that the auto-generated keys indicated in the given array should be made available for retrieval. This array contains the names of the columns in the target table that contain the auto-generated keys that should be made available. The driver will ignore the array if the given SQL statement is not an INSERT statement.

In some (uncommon) situations, a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this unless you are (1) executing a stored procedure that you know may return multiple results or (2) you are dynamically executing an unknown SQL string.

The execute method executes an SQL statement and indicates the form of the first result. You must then use the methods getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s).

Specified by:

execute in interface java.sql.Statement

Parameters:

sql - any SQL statement

columnNames - an array of the names of the columns in the inserted row that should be made available for retrieval by a call to the method getGeneratedKeys

Returns:

true if the next result is a ResultSet object; false if it is an update count or there are no more results

Throws:

java.sql.SQLException - if a database access error occurs or the elements of the String array passed to this method are not valid column names

Since:

1.4

getQueryString

public java.lang.String getQueryString()

Returns the sql statement string (question marks replaced with set parameter values) that will be (or has been) executed by the PreparedStatement that this LoggablePreparedStatement is a wrapper for.

Returns:

the statement represented by this LoggablePreparedStatement
