Calling an Oracle PL/SQL procedure in Java using a CallableStatement with a boolean IN parameter gives an PLS-00306 oracle error:

Question

I have a pl/sql procedure on an Oracle 11g that has the following parameters:

PROCEDURE validate_product
   ( product_id_in IN varchar2 , 
     username_in in va         


        

Answer 1

I think here is the issue

cstmt.registerOutParameter(6, Types.CHAR); 
cstmt.registerOutParameter(7, Types.CHAR); 

you called from java as above, But you declared in procedure out parameter as varchar2,that means there is a mismatch of datatype.

Try this code,

cstmt.registerOutParameter(6, Types.VARCHAR); 
cstmt.registerOutParameter(7, Types.VARCHAR); 

I hope this will work..
