Use CallableStatement objects to execute parameterized stored procedure calls. Use Statement objects to execute stored procedures as SQL statements with the EXEC syntax.

Using Callable Statement Objects

You can use the generic execute method of the CallableStatement class to execute any stored procedure as a parameterized query.

To return the stored procedure's results, call getResultSet. To return a count of updated rows, call getUpdateCount.

The following example shows how to execute the DownloadFile stored procedure:

CallableStatement cstmt = conn.prepareCall("DownloadFile");
cstmt.setString("Path", "test/onePiece.txt");
boolean ret = cstmt.execute();   
if (!ret) {
  int count=cstmt.getUpdateCount();
  if (count!=-1) {
    System.out.println("Affected rows: "+count);
  }
}
else {
  ResultSet rs=cstmt.getResultSet();
  while(rs.next()){
    for(int i=1;i<=rs.getMetaData().getColumnCount();i++) {
      System.out.println(rs.getMetaData().getColumnLabel(i) +"="+rs.getString(i));
    }
  }
}

Using Statement Objects

You can use the execute method of the Statement class to execute any stored procedure as an SQL statement.

To return the stored procedure's results, call getResultSet. To return a count of updated rows, call getUpdateCount.

The following example shows how to execute the DownloadFile stored procedure: (See EXECUTE Statements for more on the syntax.)

Statement stmt = conn.createStatement();
boolean ret = stmt.execute("EXEC DownloadFile Path = 'test/onePiece.txt'");

if (!ret) {
  int count=stmt.getUpdateCount();
  if (count!=-1) {
    System.out.println("Affected rows: "+count);
  }
}
else {
  ResultSet rs=stmt.getResultSet();
  while(rs.next()) {
    for(int i=1;i<=rs.getMetaData().getColumnCount();i++) {
      System.out.println(rs.getMetaData().getColumnLabel(i) +"="+rs.getString(i));
    }
  }
}
