Thread: Crosstab function Problem
Hi,
I am having problem using the crosstab function ( which is under the contrib/tablefunc directory). I have installed the tablefunc module and also installed the functions into my DB.
I am using postgresql 7.4 beta version.
I am issuing the following query,
select *
from crosstab(
'select path,name,value
from file f, metadata m
where f.id = m.file_id
and f.type=1
order by 1,2;',3)
AS DP(name text,runid text, plottype text,region text) ;
from crosstab(
'select path,name,value
from file f, metadata m
where f.id = m.file_id
and f.type=1
order by 1,2;',3)
AS DP(name text,runid text, plottype text,region text) ;
I am getting the following error message.
No function matches the given name and argument types. You may need to add explicit typecasts.
I also issued the given example in the tablefunc directory and it gave the same error.
Help me out with this,
Kuldeep.

From psql try:
\df cross*
This should list all functions starting with "cross" - if you don't see it,
the installation didn't work. If it is there, try casting the parameters:
SELECT * FROM crosstab('...'::text,3) AS...
That's assuming it takes a text for the first param, I suppose it could be
varchar.
