Executing a Procedure through JDBC

The name of the sample stored procedure is SP_D1. The username and password are guest and password. This section contains sample Java code to execute a stored procedure that returns two cursors.

To execute a stored procedure through JDBC

1. Publish the stored procedure as a TDV data service in the following directory: 
Data Services/Databases/ds
2. Write and compile the Java code, and save the class file in a directory.

See Sample Code Using MultipleCursors.

3. From the directory where you saved the class file, run the following command: 
java -classpath <path_to_csjdbc.jar_file>/csjdbc.jar\;. <MultipleCursors>

MultipleCursors is the name of the class file, and csjdbc.jar is the name of the JAR file containing the class file.

Sample Code Using MultipleCursors

import java.sql.*;
public class MultipleCursors
{
  private static final String COMPOSITE_URL =
    "jdbc:compositesw:dbapi@localhost:9401?domain=composite&dataSource=ds";
  private static final String COMPOSITE_DRIVER =
    "cs.jdbc.driver.CompositeDriver";
  private static final String COMPOSITE_USER = "guest";
  private static final String COMPOSITE_PASSWORD = "password";
  public static void main(String[] args) {
    try {
      Class.forName(COMPOSITE_DRIVER);
    } catch (ClassNotFoundException ex) {
      ex.printStackTrace();
      return;
    }
    try {
      executeProcedure();
    } catch (SQLException ex) {
      ex.printStackTrace();
      return;
    }
  }
  private static void executeProcedure()
    throws SQLException
  {
    Connection conn = DriverManager.getConnection(
      COMPOSITE_URL, COMPOSITE_USER, COMPOSITE_PASSWORD);
CallableStatement stmt = conn.prepareCall("{call SP_D1(?,?)}");
    stmt.registerOutParameter(1, Types.OTHER);
    stmt.registerOutParameter(2, Types.OTHER);
    stmt.execute();
    printResultSet((ResultSet)stmt.getObject(1));
    printResultSet((ResultSet)stmt.getObject(2));
    stmt.close();
    conn.close();
  }
  private static void printResultSet(ResultSet rs)
    throws SQLException
  {
    ResultSetMetaData metaData = rs.getMetaData();
    int rowIndex = 0;
    while (rs.next()) {
      System.out.println("Row " + rowIndex++);
      for (int i=1; i<=metaData.getColumnCount(); i++) {
        System.out.println("  Column " + i + " " + metaData.getColumnName(i) +
                           " " + rs.getString(i));
      }
    }
  }
