Hello,
I have 2 tables where each table has a column named "comments" and the
tables are related as a one to many. I want to concatenate all the
comments of the many side to the one side so I wrote the following
plpgsql function to do so.
<pre>
CREATE OR REPLACE FUNCTION fixcomments() RETURNS int4 AS
$BODY$
DECLARE mviews RECORD; i int4;
BEGIN
FOR mviews IN SELECT * FROM saleorder WHERE comments is not null
and comments <> '' LOOP
-- Now "mviews" has one record from saleorder
EXECUTE 'UPDATE sale SET comments = ' ||
quote_ident(sale.comments) || quote_ident(mviews.comments) || ' WHERE sale.id = ' || quote_ident(mviews.sale_id);
i:= i + 1; END LOOP;
RETURN i;
END;
$BODY$ LANGUAGE 'plpgsql' VOLATILE;
</pre>
I have the following error when I run this code:
<pre>
ERROR: missing FROM-clause entry for table "sale"
CONTEXT: SQL statement "SELECT 'UPDATE sale SET comments = ' ||
quote_ident(sale.comments) || quote_ident( $1 ) || ' WHERE sale.id = '
|| quote_ident( $2 )"
PL/pgSQL function "fixcomments" line 11 at execute statement
</pre>
Doesn anybody know what I am doing wrong here ?
Lacou.
