I have a simple function defined thusly:
CREATE OR REPLACE FUNCTION datemath(timestamp with time zone, int4, varchar)
RETURNS timestamp AS

DECLARE
tdat timestamp;
rdat timestamp;

IF ($1 IS NULL) THEN
TDAT := NOW();
ELSE
TDAT := $1;
END IF;
select tdat + interval ''$2 $3'' into rdat;
return rdat;
END;

LANGUAGE 'plpgsql' VOLATILE;
The problem is the interval part. How do I tell the bugger to use the second and third params as input to interval? I have tried different ways of escaping, from \’$2 $3\’ to ‘’$2 $3’’ and everything else in between, it just doesn’t like it.
Help! J
