calling a function
hi-
I set up this function in squirellSQL.
CREATE FUNCTION DISTRIBTOTALAMOUNT() RETURNS DOUBLE PARAMETER STYLE JAVA
READS SQL DATA LANGUAGE JAVA EXTERNAL NAME
'bcalc.DistGetTotalAmount.getTotal'
if I try to call it in squirrelSQL like this call DISTRIBTOTALAMOUNT() I
get not
recognized as a function or a procedure.
but if I try to create it with the same syntax it tells me it exists.
also I don't see where it is viewable in the tree. maybe I am not
looking in the right place.
I tried it outside the squirrels realm and have the exact same results
for errors.
this is overkill as all I am doing is summing a couple of rows in a
table but I could
have done something interesting like java proc|function related instead
of reads sql data. I am just trying it
out. maybe I could move some more code outside of the GUI event
handlers using this trick.
Any help is appreciated!
thanks very much,
jim

You can use VALUES to execute a function like this:
VALUES DISTRIBTOTALAMOUNT()
