• initializeWithMetaData

  void initializeWithMetaData​(DatabaseMetaData databaseMetaData)
                       throws SQLException

  Initialize using the provided DatabaseMetData.

  参数:

  databaseMetaData - used to retrieve database specific information

  抛出:

  SQLException - in case of initialization failure

• initializeWithProcedureColumnMetaData

  void initializeWithProcedureColumnMetaData​(DatabaseMetaData databaseMetaData,
                                             String catalogName,
                                             String schemaName,
                                             String procedureName)
                                      throws SQLException

  Initialize the database specific management of procedure column meta-data. This is only called for databases that are supported. This initialization can be turned off by specifying that column meta-data should not be used.

  参数:

  databaseMetaData - used to retrieve database specific information

  catalogName - name of catalog to use (or null if none)

  schemaName - name of schema name to use (or null if none)

  procedureName - name of the stored procedure

  抛出:

  SQLException - in case of initialization failure

  参数:

  parameterName - name of the parameter of column

• createDefaultOutParameter

  SqlParameter createDefaultOutParameter​(String parameterName,
                                         CallParameterMetaData meta)

  Create a default out parameter based on the provided meta-data. This is used when no explicit parameter declaration has been made.

  参数:

  parameterName - the name of the parameter

  meta - meta-data used for this call

  返回:

  the configured SqlOutParameter

• createDefaultInOutParameter

  SqlParameter createDefaultInOutParameter​(String parameterName,

  参数:

  parameterName - the name of the parameter

  meta - meta-data used for this call

  返回:

  the configured SqlInOutParameter

• createDefaultInParameter

  SqlParameter createDefaultInParameter​(String parameterName,
                                        CallParameterMetaData meta)

  Create a default in parameter based on the provided meta-data. This is used when no explicit parameter declaration has been made.

  参数:

  parameterName - the name of the parameter

  meta - meta-data used for this call

  返回:

  the configured SqlParameter

• getUserName

  String getUserName()

  Get the name of the current user. Useful for meta-data lookups etc.

  返回:

  current user name from database connection

• isReturnResultSetSupported

  boolean isReturnResultSetSupported()

  Does this database support returning ResultSets that should be retrieved with the JDBC call: Statement.getResultSet()?

• isRefCursorSupported

  boolean isRefCursorSupported()

  Does this database support returning ResultSets as ref cursors to be retrieved with CallableStatement.getObject(int) for the specified column.

• getRefCursorSqlType

  int getRefCursorSqlType()

  Get the Types type for columns that return ResultSets as ref cursors if this feature is supported.

• isProcedureColumnMetaDataUsed

  boolean isProcedureColumnMetaDataUsed()

  Are we using the meta-data for the procedure columns?

• byPassReturnParameter

  boolean byPassReturnParameter​(String parameterName)

  Should we bypass the return parameter with the specified name. This allows the database specific implementation to skip the processing for specific results returned by the database call.

• getCallParameterMetaData

  List<CallParameterMetaData> getCallParameterMetaData()

  Get the call parameter meta-data that is currently used.

  返回:

  List of CallParameterMetaData

• isSupportsCatalogsInProcedureCalls

  boolean isSupportsCatalogsInProcedureCalls()

  Does the database support the use of catalog name in procedure calls?

• isSupportsSchemasInProcedureCalls

  boolean isSupportsSchemasInProcedureCalls()
