How to call callable statement.

Callable statement is used to call PLSQL Statements.

We need to use a Callable Statement to call either a function or a procedure from OAF.

Here are the steps to call a PL/SQL procedure:

1.Create a CallableStatement with the PL/SQL block of code to call the stored procedure

2.Bind input and output variabled

3.Execute CallableStatement

4.Capture OUT parameters

5.Close the CallableStatement statement


import java.sql.CallableStatement;
import java.sql.Types;
import oracle.apps.fnd.framework.server.OADBTransaction;

public void callProcedure()
{

        String lkpCode = "XX_VAL_LIST_LKP";
        String lkpMeaning = "XX Lkp Meaning";

        CallableStatement callableStatement =
            getOADBTransaction().createCallableStatement("begin  xx_lkp_details_pkg.list_lkp(:1,:2,:3); end;",
                                                         OADBTransaction.DEFAULT);

        try {

            callableStatement.setString(1, lkpCode);
            callableStatement.setString(2, lkpMeaning);

            //registering out parameter
            callableStatement.registerOutParameter(3, Types.VARCHAR);

            callableStatement.execute();

            String tagValue = callableStatement.getString(3);

            if (tagValue != null) {

                System.out.println("Tag value: " + tagValue);

            }

        } catch (Exception e) {

            System.out.println(" XX in Catch Block of callableStatement: " +
                               e.getMessage());
        }
    }
