                           int length)
                    throws SQLException

Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large ASCII value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream. Data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from ASCII 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:

setAsciiStream in interface PreparedStatement

Parameters:

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

x - the Java input stream that contains the ASCII parameter value

length - the number of bytes in the stream

Throws:

SQLException - if a database access error occurs

setUnicodeStream

@Deprecated
public void setUnicodeStream(int parameterIndex,
                                         InputStream x,
                                         int length)
                                  throws SQLException

Deprecated.

Sets the designated parameter to the given input stream, which will have the specified number of bytes. A Unicode character has two bytes, with the first byte being the high byte, and the second being the low byte.

When a very large Unicode value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached. 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:

setUnicodeStream in interface PreparedStatement

Parameters:

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

x - a java.io.InputStream object that contains the Unicode parameter value as two-byte Unicode characters

length - the number of bytes in the stream

Throws:

SQLException - if a database access error occurs

setBinaryStream

public void setBinaryStream(int parameterIndex,
                            InputStream x,
                            int length)
                     throws SQLException

Sets the designated parameter to the given input stream, which will have the specified number of bytes. When a very large binary value is input to a LONGVARBINARY parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached.

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

Specified by:

setBinaryStream in interface PreparedStatement

Parameters:

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

x - the java input stream which contains the binary parameter value

length - the number of bytes in the stream

Throws:

SQLException - if a database access error occurs

clearParameters

public void clearParameters()
                     throws 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 the method clearParameters.

Specified by:

clearParameters in interface PreparedStatement

Throws:

SQLException - if a database access error occurs

setObject

public void setObject(int parameterIndex,
                      Object x,
                      int targetSqlType,
                      int scale)
               throws SQLException

Sets the value of the designated parameter with the given 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 given targetSqlType before being sent to the database.

If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.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 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:

SQLException - if a database access error occurs

Types

setObject

public void setObject(int parameterIndex,
                      Object x,
                      int targetSqlType)
               throws SQLException

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

Specified by:

setObject in interface 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:

SQLException - if a database access error occurs

setObject

public void setObject(int parameterIndex,
                      Object x)
               throws SQLException

Sets the value of the designated parameter using the given object. The second parameter must be of type Object; therefore, the java.lang equivalent objects should be used for built-in types.

The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument 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 the interface SQLData, the JDBC driver should call the method SQLData.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.

This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.

Specified by:

setObject in interface PreparedStatement

Parameters:

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

x - the object containing the input parameter value

Throws:

SQLException - if a database access error occurs or the type of the given object is ambiguous

execute

public boolean execute()
                throws SQLException

Executes the SQL statement in this PreparedStatement object, which may be 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 the methods executeQuery and executeUpdate.

The execute method returns a boolean to indicate the form of the first result. You must call either the method getResultSet or getUpdateCount to retrieve the result; you must call getMoreResults to move to any subsequent result(s).

Specified by:

execute in interface PreparedStatement

Returns:

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

Throws:

SQLException - if a database access error occurs or an argument is supplied to this method

See Also:

Statement.execute(java.lang.String), Statement.getResultSet(), Statement.getUpdateCount(), Statement.getMoreResults()

addBatch

public void addBatch()
              throws SQLException

Adds a set of parameters to this PreparedStatement object's batch of commands.

Specified by:

addBatch in interface PreparedStatement

Throws:

SQLException - if a database access error occurs

Since:

1.2

See Also:

setCharacterStream

public void setCharacterStream(int parameterIndex,
                               Reader reader,
                               int length)
                        throws SQLException

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 object. The data will be read from the stream as needed until end-of-file is reached. 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 PreparedStatement

Parameters:

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

reader - the java.io.Reader object that contains the Unicode data

length - the number of characters in the stream

public void setRef(int i,
                   Ref x)
            throws SQLException

Sets the designated parameter to the given REF(<structured-type>) value. The driver converts this to an SQL REF value when it sends it to the database.

Specified by:

setRef in interface PreparedStatement

Parameters:

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

x - an SQL REF value

Throws:

SQLException - if a database access error occurs

x - a Blob object that maps an SQL BLOB value

Throws:

SQLException - if a database access error occurs

Since:

1.2

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

Sets the designated parameter to the given Clob object. The driver converts this to an SQL CLOB value when it sends it to the database.

getMetaData

public ResultSetMetaData getMetaData()
                              throws SQLException

Retrieves a ResultSetMetaData object that contains information about the columns of the ResultSet object that will be returned when this PreparedStatement object is executed.

Because a PreparedStatement object is precompiled, it is possible to know about the ResultSet object that it will return without having to execute it. Consequently, it is possible to invoke the method getMetaData on a PreparedStatement object rather than waiting to execute it and then invoking the ResultSet.getMetaData method on the ResultSet object that is returned.

NOTE: Using this method may be expensive for some drivers due to the lack of underlying DBMS support.

Specified by:

getMetaData in interface PreparedStatement

Returns:

the description of a ResultSet object's columns or null if the driver cannot return a ResultSetMetaData object

Throws:

SQLException - if a database access error occurs

Since:

1.2

setDate

public void setDate(int parameterIndex,
                    Date x,
                    Calendar cal)
             throws SQLException

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

Specified by:

setDate in interface 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:

SQLException - if a database access error occurs

Since:

1.2

setTime

                    Calendar cal)
             throws SQLException

Sets the designated parameter to the given java.sql.Time value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIME value, which the driver then sends to the database. With a Calendar object, the driver can calculate the time taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

Specified by:

setTime in interface PreparedStatement

Parameters:

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

x - the parameter value

setTimestamp

public void setTimestamp(int parameterIndex,
                         Timestamp x,
                         Calendar cal)
                  throws SQLException

Sets the designated parameter to the given java.sql.Timestamp value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIMESTAMP value, which the driver then sends to the database. With a Calendar object, the driver can calculate the timestamp taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

Specified by:

setTimestamp in interface PreparedStatement

setNull

public void setNull(int paramIndex,
                    int sqlType,
                    String typeName)
             throws SQLException

Sets the designated parameter to SQL NULL. This version of the method setNull should be used for user-defined types and REF type parameters. Examples of user-defined 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-defined 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-defined 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-defined or REF type, the given typeName is ignored.

Specified by:

setNull in interface PreparedStatement

Parameters:

paramIndex - 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-defined type; ignored if the parameter is not a user-defined type or REF

Throws:

SQLException - if a database access error occurs

Since:

1.2

setURL

public void setURL(int parameterIndex,
                   URL x)
            throws SQLException

Sets the designated parameter to the given java.net.URL value. The driver converts this to an SQL DATALINK value when it sends it to the database.

Specified by:

setURL in interface PreparedStatement

Parameters:

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

x - the java.net.URL object to be set

Throws:

SQLException - if a database access error occurs

Since:

1.4

                                       throws SQLException

Retrieves the number, types and properties of this PreparedStatement object's parameters.

Specified by:

getParameterMetaData in interface PreparedStatement

Returns:

a ParameterMetaData object that contains information about the number, types and properties of this PreparedStatement object's parameters

Throws:

SQLException - if a database access error occurs

Since:

1.4

close

public void close()
           throws SQLException

Description copied from class: StatementWrapper

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.

Calling the method close on a Statement object that is already closed has no effect.

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

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Statement

Overrides:

close in class StatementWrapper

Throws:

SQLException - if a database access error occurs

closeOnCompletion

public void closeOnCompletion()
                       throws SQLException

setMaxFieldSize

public void setMaxFieldSize(int max)
                     throws SQLException

Description copied from class: StatementWrapper

Sets the limit for the maximum number of bytes in a ResultSet column storing character or binary values to the given number of bytes. 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 Statement

Overrides:

setMaxFieldSize in class StatementWrapper

Parameters:

max - the new column size limit in bytes; zero means there is no limit

Throws:

SQLException - if a database access error occurs or the condition max >= 0 is not satisfied

See Also:

StatementWrapper.getMaxFieldSize()

setMaxRows

public void setMaxRows(int max)
                throws SQLException

Specified by:

setMaxRows in interface Statement

Overrides:

setMaxRows in class StatementWrapper

Parameters:

max - the new max rows limit; zero means there is no limit

Throws:

SQLException - if a database access error occurs or the condition max >= 0 is not satisfied

                       throws SQLException

Description copied from class: StatementWrapper

Gives the driver a hint as to the direction in which rows will be processed in ResultSet objects 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 Statement

Overrides:

setFetchDirection in class StatementWrapper

Parameters:

direction - the initial direction for processing rows

Throws:

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
