createTableAppendColumn in class JdbcAdapter

Parameters:

sqlBuffer - the StringBuffer to append the column type to

column - the DbAttribute defining the column to append type for

getSqlTreeProcessor

public SQLTreeProcessor getSqlTreeProcessor()

Specified by:

getSqlTreeProcessor in interface DbAdapter

Overrides:

public SQLAction getAction(Query query,
 DataNode node)

Description copied from class: JdbcAdapter

Uses JdbcActionBuilder to create the right action.

Specified by:

getAction in interface DbAdapter

Overrides:

getAction in class JdbcAdapter

configureExtendedTypes

protected void configureExtendedTypes(ExtendedTypeMap map)

Installs appropriate ExtendedTypes as converters for passing values between JDBC and Java layers.

Overrides:

configureExtendedTypes in class JdbcAdapter

Since:
