Hi All
I have a question about CallableStatement in JDBC 
Driver.
There is the stored procedure with 2 in parameters 
and 2 out parameters (RETURNS ...).
What should I write in connection.prepareCall() 
method?
I use connection.prepareCall("{call 
sp_procedure (?,?,?,?)}") and get SQLException with message:
"GDSException: org.firebirdsql.gds.GDSException: 
Dynamic SQL Error parameter mismatch for procedure SP_PROCEDURE"
What is wrong?
Please help.
P.S. Is there the documentation for JDBC 
Driver
Best regards
Dmitri
