Peter,
Thank you for your reply.

MySQL support also suggested the same thing. Problem is, values in the
OUT variable can be retrieved only from a future SQL query. But we are
trying to call this procedure from a C program. C Program can parse
the result set if it is an output from a simple SELECT statement. I am
finding it difficult achieve something like below:
Here is a sample of informix function:
Create function test()
Returning integer, smallint, char(1), varchar(65);
Foreach
select col1, col2
into p_col1, p_col2
from table1
where <where_clause>
foreach
select col1, col2, col3, col4
into i_col1, i_col2, i_col3, i_col4
from table2
where i_col1 = p_col1
and i_col2 = p_col2
if p_col3 = <some_thing> then
do_some_calculations;
let p_string1 = <some_thing>
end if;
if p_col4 = <some_thing> then
do_some_calculations;
let p_string2 = <some_thing>;
end if;
return i_col3, i_col4, p_string1, p_string2 with resume;
end foreach
End foreach
End function;
Thank you for your help
Dinesh

Dinesh,
A stored func returns a scalar. To return multiple values, use an sproc
declaring the INOUT variables you need, & pick up their values in the
calling code after the sproc has executed.

Hi,
I am trying to write a function which returns multiple values.
I don't know if this is allowed or not but i am not able to create this
function. I get the following error:
ERROR 1064 (42000): You have an error in your SQL syntax; check
the manual that corresponds to your MySQL server version for the right
syntax to use near '
integer,
integer, ' at line 7
I have attached the function i am trying to create. Please
refer to the attached thread for contract related information.
I would appreciate if somebody can give me a call so that i can
clear few other questions.
Thanks
Dinesh Anchan
