Function Documentation

change_truth_value_of_condition()

static Item * change_truth_value_of_condition ( Parse_context *  pc, Item *  expr, Item::Bool_test  truth_test  )

static

Apply a truth test to given expression.

Either the expression can implement it itself, or we create an Item node to implement it by wrapping the expression. Expression is possibly an incomplete predicate.

Parameters

pc	current parse context
expr	expression
truth_test	test to apply

Returns

the resulting expression, or NULL if error

handle_sql2003_note184_exception()

static Item * handle_sql2003_note184_exception ( Parse_context *  pc, Item *  left, bool  is_negation, Item *  expr  )

static

Helper to resolve the SQL:2003 Syntax exception 1) in <in predicate>.

See SQL:2003, Part 2, section 8.4 <in predicate>, Note 184, page 383. This function returns the proper item for the SQL expression left [NOT] IN ( expr )

Parameters

pc	the current parse context
left	the in predicand
is_negation	false for IN predicates, true for NOT IN predicates
expr	first and only expression of the in value list

Returns

an expression representing the IN predicate.
