getProcedures() - Listing Stored Procedures

This section describes how to get a list of stored procedures in the database server.

If you want to get a list of stored procedures through the JDBC interface, you can use the getProcedures() method on the DatabaseMetaData object as shown in the program program below:

/* OracleCallGetProcedures.java
 * Copyright (c) HerongYang.com. All Rights Reserved.
 */
import java.sql.*;
public class OracleCallGetProcedures {
  public static void main(String [] args) {
    Connection con = null;
    try {
      oracle.jdbc.pool.OracleDataSource ds
        = new oracle.jdbc.pool.OracleDataSource();
      ds.setDriverType("thin");
      ds.setServerName("localhost");
      ds.setPortNumber(1521);
      ds.setDatabaseName("XE");
      ds.setUser("Herong");
      ds.setPassword("TopSecret");
      con = ds.getConnection();
      DatabaseMetaData meta = con.getMetaData();

// Listing all stored procedures
      ResultSet res = meta.getProcedures(null, "HERONG", "%");
      System.out.println("Stored procedures:");
      while (res.next()) {
        System.out.println(
          "   "+res.getString("PROCEDURE_CAT")
          + ", "+res.getString("PROCEDURE_SCHEM")
          + ", "+res.getString("PROCEDURE_NAME"));
      }
      res.close();

// Listing all tables
      res = meta.getTables(null, "HERONG", "%", null);
      System.out.println("Tables:");
      while (res.next()) {
        System.out.println(
          "   "+res.getString("TABLE_CAT")
          + ", "+res.getString("TABLE_SCHEM")
          + ", "+res.getString("TABLE_NAME"));
      }
      res.close();

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

The output of the program looks good and clean with newer versions of JDK, Oracle Server and JDBC Driver:

herong> java -cp .;ojdbc11.jar OracleCallGetProcedures

Stored procedures:
   null, HERONG, COUNTCHAR
   null, HERONG, UPDATEPOINT
Tables:
   null, HERONG, PROFILE

But when running the same program with JDK 1.6, Oracle Server 10.2 and ojdbc14.jar, the output was a surprise to me:

herong> java -cp .;ojdbc11.jar OracleCallGetProcedures

Stored procedures:
   null, HERONG, COUNTCHAR
   null, HERONG, UPDATEPOINT
Tables:
   null, HERONG, BIN$RJZ2RPSgRIWblY7KVAPbaQ==$0
   null, HERONG, BIN$gFli9YvMSzuaH8TNsZA/iw==$0
   null, HERONG, PROFILE

Note that there were some tables named as "BIN$..." in the database. Those tables were copies of dropped tables stored in the recycle bin, just in case you want to restore them.
