buildWhereClause

protected void buildWhereClause(EntityImpl entityContext,
                                java.lang.StringBuffer buffer,
                                AttributeDefImpl[] keyCols,
                                java.lang.Object rowid)

Construct a SQL WHERE clause for the Entity into the designated Buffer, based upon the Source Columns. This routine will construct a SQL WHERE clause in the StringBuffer passed. It does this by appending the various components of the WHERE Clause (based upon Primary Key columns) into the buffer area.

For now it's private. We'll only consider it public when we sort out all of the issues with Sources/Sinks.

The presence or absence of the ROWID value determines whether the ROWID will be used for Row access.

Parameters:

buffer - the area into which the WHERE Clause will be placed.

keyCols - the Primary key columns.

rowid - the ROWID for the ROW if known.

buildInsertStatement
