From 07a65b22554d54455de5bc791a48fb0542f48791 Mon Sep 17 00:00:00 2001 From: "Marc G. Fournier" Date: Wed, 13 Nov 1996 20:56:15 +0000 Subject: Commit of a *MAJOR* patch from Dan McGuirk Changes: * Unique index capability works using the syntax 'create unique index'. * Duplicate OID's in the system tables are removed. I put little scripts called 'duplicate_oids' and 'find_oid' in include/catalog that help to find and remove duplicate OID's. I also moved 'unused_oids' from backend/catalog to include/catalog, since it has to be in the same directory as the include files in order to work. * The backend tries converting the name of a function or aggregate to all lowercase if the original name given doesn't work (mostly for compatibility with ODBC). * You can 'SELECT NULL' to your heart's content. * I put my _bt_updateitem fix in instead, which uses _bt_insertonpg so that even if the new key is so big that the page has to be split, everything still works. * All literal references to system catalog OID's have been replaced with references to define'd constants from the catalog header files. * I added a couple of node copy functions. I think this was a preliminary attempt to get rules to work. --- src/include/nodes/parsenodes.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'src/include/nodes/parsenodes.h') diff --git a/src/include/nodes/parsenodes.h b/src/include/nodes/parsenodes.h index 9e61aeffbc..01c037b54f 100644 --- a/src/include/nodes/parsenodes.h +++ b/src/include/nodes/parsenodes.h @@ -6,7 +6,7 @@ * * Copyright (c) 1994, Regents of the University of California * - * $Id: parsenodes.h,v 1.6 1996/11/04 07:18:17 scrappy Exp $ + * $Id: parsenodes.h,v 1.7 1996/11/13 20:56:15 scrappy Exp $ * *------------------------------------------------------------------------- */ @@ -217,6 +217,7 @@ typedef struct IndexStmt { List *rangetable; /* range table, filled in by transformStmt() */ bool *lossy; /* is index lossy? */ + bool unique; /* is index unique? */ } IndexStmt; /* ---------------------- @@ -594,7 +595,7 @@ typedef struct ResTarget { char *name; /* name of the result column */ List *indirection; /* array references */ Node *val; /* the value of the result - (A_Expr or Attr) */ + (A_Expr or Attr) (or A_Const) */ } ResTarget; /* -- cgit v1.2.1
