createCommand(String commandName, String tableName) Creates command identified by commandName on table tableName.
Returns null if command specified by commandName was not found.
getJDBCConnection() Returns JDBC connection.
Commands must test if the connection is not open yet; if you simply call
openJDBCConnection without test (and the connection will be open by user),
a DDLException throws.
Creates command identified by commandName. Command names will include
create/rename/drop table/view/index/column and comment table/column. It
returns null if command specified by commandName was not found. Used
system allows developers to extend db-specification files and simply
address new commands (everybody can implement createXXXCommand()).
Creates command identified by commandName on table tableName.
Returns null if command specified by commandName was not found. It does not
check tableName existency; it simply waits for relevant execute() command
which fires SQLException.
Returns JDBC connection.
Commands must test if the connection is not open yet; if you simply call
openJDBCConnection without test (and the connection will be open by user),
a DDLException throws. This is a self-checking mechanism; you must always
close used connection.
Opens JDBC Connection.
This method usually calls command when it need to process something.
But you can call it explicitly and leave connection open until last
command gets executed. Don't forget to close it.
