Function pass1Validations

src/dsql/StmtNodes.cpp:10903–10912

The csb->csb_validate_expr becomes true if an ancestor of the current node (the one being passed in) in the parse tree is a validation. "Ancestor" does not include the current node being passed in as an argument. If we are in a "validate subtree" (as determined by the csb->csb_validate_expr), we must not post update access to the fields involved in the validation clause. (See the call for CMP_post

// post update access to the fields involved in the validation clause.
// (See the call for CMP_post_access in this function.)
static void pass1Validations(thread_db* tdbb, CompilerScratch* csb, Array<ValidateInfo>& validations)
{
	AutoSetRestore<bool> autoValidateExpr(&csb->csb_validate_expr, true);

	for (Array<ValidateInfo>::iterator i = validations.begin(); i != validations.end(); ++i)
	{
		DmlNode::doPass1(tdbb, csb, i->boolean.getAddress());
		DmlNode::doPass1(tdbb, csb, i->value.getAddress());
	}
