Hello all,
Hereby an alpha version regarding the: TODO Item: SQL-language reference parameters by name. I am sending this patch to check if I am on the right track. So please take a look at this if possible. What does this patch do? As discussed in thread: http://archives.postgresql.org/pgsql-hackers/2007-10/msg01490.php, this patch adds an additional parameter (char **argnames) to pg_parse_and_rewrite and pg_analyze_and_rewrite and ParseState. When transformColumnRef is about to report an error for a non existing column,a final match is performed to see if the non existing column is a parameter name. (argnames) If true, then a new node is created by transformParamRef NOTE: - This patch is created using MSVC++ ! - Nothing is done yet for polymorphic arguments. My test where: create table tbl1(id serial,field1 integer,field2 varchar); insert into tbl1 (field1,field2) values(11,'zzzz'); insert into tbl1 (field1,field2) values(22,'yyyy'); create or replace function func1(par1 integer,par2 integer,par3 varchar) returns setof record as $$ select par1::text, par2, par1+par2, par2+par1, par1+field1, (field1+par2)::varchar, par3, field2 || ' ' || par3 from tbl1; $$ language sql; select func1(2,4,'aaaa'); select * from func1(5,16,'bbbb') as (a text ,b int ,c int, e int, f int,g varchar,h varchar,i text); results: "(2,4,6,6,13,15,aaaa,"zzzz aaaa")" "(2,4,6,6,24,26,aaaa,"yyyy aaaa")" And "5";16;21;21;16;"27";"bbbb";"zzzz bbbb" "5";16;21;21;27;"38";"bbbb";"yyyy bbbb" Regards, Gevik
