From 8536c962614a55d33baa283a7901bb167a43978a Mon Sep 17 00:00:00 2001 From: "Thomas G. Lockhart" Date: Fri, 29 May 1998 14:00:24 +0000 Subject: Do type conversion to match columns in UNION clauses. Currently force the type to match the _first_ select in the union. Move oper_select_candidate() from parse_func.c to parse_oper.c. Throw error inside of oper_inexact() if no match for binary operators. Check more carefully that types can be coerced even if there is only one candidate operator in oper_inexact(). Fix up error messages for more uniform look. Remove unused code. Fix up comments. --- src/backend/parser/parse_expr.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'src/backend/parser/parse_expr.c') diff --git a/src/backend/parser/parse_expr.c b/src/backend/parser/parse_expr.c index af8424ed0c5..007983adf7e 100644 --- a/src/backend/parser/parse_expr.c +++ b/src/backend/parser/parse_expr.c @@ -7,7 +7,7 @@ * * * IDENTIFICATION - * $Header: /cvsroot/pgsql/src/backend/parser/parse_expr.c,v 1.28 1998/05/09 23:29:53 thomas Exp $ + * $Header: /cvsroot/pgsql/src/backend/parser/parse_expr.c,v 1.29 1998/05/29 14:00:21 thomas Exp $ * *------------------------------------------------------------------------- */ @@ -302,12 +302,12 @@ transformExpr(ParseState *pstate, Node *expr, int precedence) break; } -/* These nodes do _not_ come from the original parse tree, +/* Some nodes do _not_ come from the original parse tree, * but result from parser transformation in this phase. * At least one construct (BETWEEN/AND) puts the same nodes * into two branches of the parse tree; hence, some nodes * are transformed twice. - * These cases below come from transforming function calls. + * The three cases below come from transforming function calls. * Let's try just passing them through... * - thomas 1998-03-14 */ -- cgit v1.2.3
