So... this may sound stupid, but according to the documentation I've
read, this should be possible.
Why can I do this:
tError := ''Here is some error text. I wanted to wrap it '' ||
''so my code would look nicer. So, I of course '' ||
''thought of concatenation. '';
RAISE EXCEPTION ''%'', tError;
But I can't do this:
RAISE EXCEPTION ''Here is some error text. I wanted to wrap it '' ||
''so my code would look nicer. So, I of course '' ||
''thought of concatenation. '';
And yet the documentation uses this as an example:
RAISE EXCEPTION ''View '' || key || '' not found'';
So I made up an example to test this:
CREATE FUNCTION sp_test()
RETURNS BOOLEAN AS '
DECLARE
tStuff VARCHAR(10) := ''Print Me'';
BEGIN
RAISE EXCEPTION ''I would like to say : '' || tStuff || '', now!'';
RETURN TRUE;
END;
' LANGUAGE 'plpgsql';
Postgres returns this error:
mydb=# SELECT sp_test();
NOTICE: plpgsql: ERROR during compile of sp_test near line 4
ERROR: parse error at or near "|"
Which told me it was whining about the ||'s. So I wrote this:
CREATE FUNCTION sp_test()
RETURNS BOOLEAN AS '
DECLARE
tStuff VARCHAR(10) := ''Print Me'';
BEGIN
RAISE EXCEPTION ''I would like to say : %, now!'', tStuff;
RETURN TRUE;
END;
' LANGUAGE 'plpgsql';
Which returns no errors, and runs as expected.
I first noticed this error in 7.1.1, but it's still around in 7.1.3.
What's the deal?
