Method Detail

createBlob

java.sql.Blob createBlob()
                  throws java.sql.SQLException

Create Blob object.

Specified by:

createBlob in interface java.sql.Connection

Returns:

instance of FirebirdBlob.

Throws:

java.sql.SQLException - if something went wrong.

getIscEncoding

java.lang.String getIscEncoding()
                         throws java.sql.SQLException

Get current ISC encoding.

Returns:

current ISC encoding.

Throws:

java.sql.SQLException

setTransactionParameters

@Deprecated
void setTransactionParameters(int isolationLevel,
                                           int[] parameters)
                                    throws java.sql.SQLException

Deprecated. use setTransactionParameters(int, TransactionParameterBuffer) instead.

Set transaction parameters for the specified isolation level. They will take effect only on the newly started transaction.

Parameters:

isolationLevel - JDBC isolation level.

parameters - array of TPB parameters, see all TPB_* constants.

Throws:

java.sql.SQLException - if specified transaction parameters cannot be set.

getTransactionParameters

TransactionParameterBuffer getTransactionParameters(int isolationLevel)
                                             throws java.sql.SQLException

Get transaction parameters for the specified transaction isolation level.

Parameters:

isolationLevel - isolation level defined in the Connection interface.

Returns:

instance of TransactionParameterBuffer containing current transaction parameters.

Throws:

java.sql.SQLException - if error occured obtaining transaction parameters.

createTransactionParameterBuffer

TransactionParameterBuffer createTransactionParameterBuffer()
                                                     throws java.sql.SQLException

Create new instance of TransactionParameterBuffer.

Returns:

empty instance of TransactionParameterBuffer.

Throws:

java.sql.SQLException - if error occured during this operation.

setTransactionParameters

void setTransactionParameters(int isolationLevel,
                              TransactionParameterBuffer tpb)
                       throws java.sql.SQLException

Set transaction parameters for the specified transaction isolation level. This method replaces the default TPB mapping with the specified one, changes will be effective from the next transaction start.

Parameters:

isolationLevel - isolation level defined in the Connection interface.

tpb - instance of TransactionParameterBuffer with parameters to set.

Throws:

java.sql.SQLException - if error occured during this operation.

setTransactionParameters

void setTransactionParameters(TransactionParameterBuffer tpb)
                       throws java.sql.SQLException

Set transaction parameters for the next transactions. This method does not change the TPB mapping, but replaces the mapping for the current transaction isolation until Connection.setTransactionIsolation(int) is called.

Method cannot be called when transaction has already started.

Parameters:

tpb - instance of TransactionParameterBuffer with new transaction parameters.

Throws:

java.sql.SQLException - if method is called within a transaction.

isUseFirebirdAutoCommit

boolean isUseFirebirdAutoCommit()

Returns:

true if this connection is configured to use isc_tpb_autocommit when in auto commit.

getFbDatabase

FbDatabase getFbDatabase()
                  throws java.sql.SQLException

Provides access to the low-level connection handle.

WARNING using this connection handle directly may bring the JDBC connection in an inconsistent state.

Returns:

The low-level connection handle.

Throws:

java.sql.SQLException
