RE: Calling a stored procedure -- JAVA400-L

Title: RE: Calling a stored procedure

One comment for people who are still using VAJ 3.02

The IBM AS400 Toolbox for Java 3.0 that is provided with VAJ 3.02
doesn't support this functionnality (using librairies) correctly.

We have replaced it by a recent version of the toolbox and it works.

This problem doesn't exist in VAJ 3.5

Cheers

Gilles

What you are doing seems reasonable and should work. I tried the following
and it worked for me. Do you see anything different between what you did
and what I am doing? In my case the procedure is in library 'dawjdbc',
which is after the other two in the library list.

      try
      {
         DriverManager.registerDriver(new
com.ibm.as400.access.AS400JDBCDriver());

         connection = DriverManager.getConnection
("jdbc:as400://xxxxx;naming=system;errors=full;user=xxx;password=xxxx;");
         statement = connection.createStatement();
         runCommand(connection, "ADDLIBLE DAWJDBC");
         runCommand(connection, "ADDLIBLE FRED");
         runCommand(connection, "ADDLIBLE DAW");

         clblStmt = connection.prepareCall( "{CALL TEST_SP2(?, ?, ?, ?, ?)
}" );
         clblStmt.setInt(1, 123);
         clblStmt.setNull(2, Types.INTEGER);
         clblStmt.setNull(3, Types.INTEGER);
         clblStmt.setNull(4, Types.INTEGER);
         clblStmt.setString(5, "Hi Mom");
         rs = clblStmt.executeQuery();

if (rs.next())
System.out.println(rs.getString(1));

}
catch (Exception e) { e.printStackTrace(); }

   static void runCommand(Connection connection, String command)
                          throws SQLException
   {
      Statement statement = connection.createStatement();

      // We run commands via the QCMDEXC stored procedure. That procedure
      // requires the length of the command be included with the command
      // specified in precision 15, scale 5 format. That is,
      // "CALL QSYS.QCMDEXC('command-to-run', 000000nnnn.00000)"
      String commandLength = "0000000000" + command.length();
             commandLength = commandLength.substring(commandLength.length()
- 10) +
                               ".00000";

String SQLCommand = "CALL QSYS/QCMDEXC('" + command +
"', " + commandLength + ")";

      statement.executeUpdate(SQLCommand);
      statement.close();
   }

Hi,

I have an unexpected behaviour when i call my (RPG) stored procedure on the

AS400. I am using the AS400 toolbox.

I have a pool of connections.
For each connection i set 3 library lists in java. (i do an execute command

"AddLibl")
I know that the last lib that is added will be used first.

When i call the stored procedure i don't prefix the call with name of the
lib.
(e.g CALL EVALUATE_ACCOUNT instead of CALL MYLIB.EVALUATE_ACCOUNT)

I am surprised to see that if the stored procedure is not in the first
library, it is not
found (searched?) in the other libraries.

This is a bit annoying since i have some stored proc in my developpement
environment,
but some others are already in my integration environment.

I did'nt expected such a behaviour.
I use the naming = system convention.

Any one can help. I pretty sure it can search the stored proc in the other
libraries.
We do that with the datasource of websphere. I don't expect something
different
with classic JDBC.
All the examples i can find in the IBM document use something like
MYLIBNAME.MYPROCEDURE

I have tried that, also specifying libraries in the connection URL (say
ANOTHERLIB)
If MYPROCEDURE is not found in MYLIBNAME it is not found/searched in
ANOTHERLIB.

Should i set something special on my profile on the AS400?

Many thanks

Gilles
