isReturnResultSetSupported

public boolean isReturnResultSetSupported()

Description copied from interface: CallMetaDataProvider

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

Specified by:

isReturnResultSetSupported in interface CallMetaDataProvider

Overrides:

isReturnResultSetSupported in class GenericCallMetaDataProvider

isRefCursorSupported

public boolean isRefCursorSupported()

Description copied from interface: CallMetaDataProvider

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

Specified by:

isRefCursorSupported in interface CallMetaDataProvider

Overrides:

isRefCursorSupported in class GenericCallMetaDataProvider

getRefCursorSqlType

public int getRefCursorSqlType()

Description copied from interface: CallMetaDataProvider

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

Specified by:

getRefCursorSqlType in interface CallMetaDataProvider

Overrides:

getRefCursorSqlType in class GenericCallMetaDataProvider

metaDataSchemaNameToUse

public String metaDataSchemaNameToUse(String schemaName)

Description copied from interface: CallMetaDataProvider

Specified by:

metaDataSchemaNameToUse in interface CallMetaDataProvider

Overrides:

metaDataSchemaNameToUse in class GenericCallMetaDataProvider

createDefaultOutParameter

public SqlParameter createDefaultOutParameter(String parameterName,
                                              CallParameterMetaData meta)

Description copied from interface: CallMetaDataProvider

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

Specified by:

createDefaultOutParameter in interface CallMetaDataProvider

Overrides:

createDefaultOutParameter in class GenericCallMetaDataProvider

Parameters:

meta - meta data used for this call

Returns:

the configured SqlOutParameter

public boolean byPassReturnParameter(String parameterName)

Description copied from interface: CallMetaDataProvider

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.

Specified by:

byPassReturnParameter in interface CallMetaDataProvider

Overrides:
