Method Summary

Methods

Modifier and Type	Method and Description
protected void	createInnerSelectPart(Query query, Appendable out) Inner select select with under aliases assignment and order columns (have to propagate to outer select)
protected void	createOuterPart(String innerSelect, Query query, Appendable out) Outer part of select with sorting
protected void	createRowOrderPart(Query query, Appendable out, boolean asOrderAlias) Creating RowNumber column
protected void	createWherePart(Query query, Appendable out) Where clause for inner select
protected String	getColumnType(MetaColumn column) Returns a database column type
String	getJdbcDriver() Returns a JDBC driver class name.
String	getJdbcUrl() Returns a default JDBC URL
boolean	isCatalog() Does the database support a catalog? The feature supports: MySqlDialect and MSSqlDialect.
Appendable	printAlterTableAddColumn(MetaColumn column, Appendable out) Print a SQL sript to add a new column to the table
Appendable	printColumnDeclaration(MetaColumn column, String aName, Appendable out) Print a SQL to create column
Appendable	printColumnOrderAlias(MetaColumn column, Appendable out) Print a full SQL column alias name by sample: o__ - used for as order alias
