Method Detail

connectedConfiguration

public void connectedConfiguration(Connection conn)
                            throws SQLException

Description copied from class: DBDictionary

This method is called when the dictionary first sees any connection. It is used to initialize dictionary metadata if needed. If you override this method, be sure to call super.connectedConfiguration.

Overrides:

connectedConfiguration in class DBDictionary

Throws:

SQLException

getColumns

public Column[] getColumns(DatabaseMetaData meta,
                           String catalog,
                           String schemaName,
                           String tableName,
                           String columnName,
                           Connection conn)
                    throws SQLException

Description copied from class: DBDictionary

Reflect on the schema to find columns matching the given table and column patterns.

Overrides:

getColumns in class AbstractSQLServerDictionary

Throws:

SQLException

getColumns

public Column[] getColumns(DatabaseMetaData meta,
                           DBIdentifier catalog,
                           DBIdentifier schemaName,
                           DBIdentifier tableName,
                           DBIdentifier columnName,
                           Connection conn)
                    throws SQLException

Description copied from class: DBDictionary

Reflect on the schema to find columns matching the given table and column patterns.

Overrides:

getColumns in class DBDictionary

Throws:

SQLException

appendLength

protected void appendLength(SQLBuffer buf,
                            int type)

Overrides:

appendLength in class DBDictionary

appendXmlComparison

public void appendXmlComparison(SQLBuffer buf,
                                String op,
                                FilterValue lhs,
                                FilterValue rhs,
                                boolean lhsxml,
                                boolean rhsxml)

If this dictionary supports XML type, use this method to append xml predicate.

Overrides:

appendXmlComparison in class DBDictionary

Parameters:

buf - the SQL buffer to write the comparison

op - the comparison operation to perform

lhs - the left hand side of the comparison

rhs - the right hand side of the comparison

lhsxml - indicates whether the left operand maps to xml

rhsxml - indicates whether the right operand maps to xml

getSchemaCase

public String getSchemaCase()

Return DB specific schemaCase

Specified by:

getSchemaCase in interface IdentifierConfiguration

Overrides:

getSchemaCase in class DBDictionary

Returns:

upper, lower, or preserve

setSupportsXMLColumn

public void setSupportsXMLColumn(boolean b)

Overrides:

setSupportsXMLColumn in class DBDictionary

Parameters:

b - boolean representing if XML columns are supported

isFatalException

public boolean isFatalException(int subtype,
                                SQLException ex)

Description copied from class: DBDictionary

Determine if the given SQL Exception is fatal or recoverable (such as a timeout). This implementation always returns true (i.e. all exceptions are fatal). The current dictionary implementation can overwrite this method to mark certain exception conditions as recoverable error.

Overrides:

isFatalException in class DBDictionary

Parameters:

subtype - A constant indicating the category of error as defined in StoreException.

ex - original SQL Exception as raised by the database driver.

Returns:

false if the error is fatal.

getLOBStream

public InputStream getLOBStream(JDBCStore store,
                                ResultSet rs,
                                int column)
                         throws SQLException

Obtain an InputStream by using ResultSet.getBlob(int) and Blob.getBinaryStream(). Unfortunately this will load entire BLOB into memory. The alternative ResultSet.getBinaryStream(int) provides true streaming but the stream can be consumed only as long as ResultSet is open.

Overrides:

getLOBStream in class DBDictionary

Throws:

SQLException

getCharacterStream

public Reader getCharacterStream(ResultSet rs,
                                 int column)
                          throws SQLException

Obtain a Reader by using ResultSet.getClob(int) and Clob.getCharacterStream(). Unfortunately this will load entire CLOB into memory. The alternative ResultSet.getCharacterStream(int) provides true streaming but the stream can be consumed only as long as ResultSet is open.

Overrides:

getCharacterStream in class DBDictionary

Throws:

SQLException

indexOf

public void indexOf(SQLBuffer buf,
                    FilterValue str,
                    FilterValue find,
                    FilterValue start)

Description copied from class: DBDictionary

Invoke this database's indexOf function.

Overrides:

indexOf in class DBDictionary

Parameters:

buf - the SQL buffer to write the indexOf invocation to

str - a query value representing the target string

find - a query value representing the search string

start - a query value representing the start index, or null to start at the beginning

appendSelectRange

protected void appendSelectRange(SQLBuffer buf,
                                 long start,
                                 long end,
                                 boolean subselect)

Description copied from class: DBDictionary

If this dictionary can select ranges, use this method to append the range SQL.
