String addEscapeChars

(

String

value

)

void addJoinClause	(	String	leftName,
		String	rightName,
		int	semantic
	)

Overridden to not call the super implementation.

Parameters:

	leftName	the table name on the left side of the clause
	rightName	the table name on the right side of the clause
	semantic	the join semantic

void addOrderByAttributeOrdering

		String	table,
		String	columns,
		String	values
	)

String assembleJoinClause	(	String	leftName,
		String	rightName,
		int	semantic
	)

Overridden to construct a valid SQL92 JOIN clause as opposed to the Oracle-like SQL the superclass produces.

Parameters:

	leftName	the table name on the left side of the clause
	rightName	the table name on the right side of the clause
	semantic	the join semantic

Returns:

the join clause

String assembleSelectStatementWithAttributes	(	NSArray	attributes,

		String	selectString,
		String	columnList,
		String	tableList,
		String	whereClause,
		String	joinClause,
		String	orderByClause,
		String	lockClause
	)

Overridden to handle correct placements of join conditions and to handle DISTINCT fetches with compareCaseInsensitiveA(De)scending sort orders.

Parameters:

	attributes	the attributes to select
	lock	flag for locking rows in the database
	qualifier	the qualifier to restrict the selection
	fetchOrder	specifies the fetch order
	columnList	the SQL columns to be fetched
	tableList	the the SQL tables to be fetched
	whereClause	the SQL where clause
	joinClause	the SQL join clause
	orderByClause	the SQL sort order clause
	lockClause	the SQL lock clause

Returns:

the select statement
