List of uniqueJoin() Examples

Examples of uniqueJoin()

org.apache.derby.iapi.sql.compile.Optimizable.uniqueJoin()
Does this optimizable have a uniqueness condition on the given predicate list, and if so, how many unique keys will be returned per scan. @param predList The predicate list to check @return <= 0 means there is no uniqueness condition> 0 means there is a uniqueness condition, and the return value is the number of rows per scan. @exception StandardException Thrown on error
