Java is a method that invokes the MySQL stored procedure and gets the return value

This article illustrates how Java can invoke a MySQL stored procedure and get a return value. Share with you for your reference. The details are as follows:

private void empsInDept(Connection myConnect, int deptId) throws SQLException {
 CallableStatement cStmt = myConnect.prepareCall("{CALL sp_emps_in_dept(?)}");
 cStmt.setInt(1, deptId);
 cStmt.execute();
 ResultSet rs1 = cStmt.getResultSet();
 while (rs1.next()) {
    System.out.println(rs1.getString("department_name") + " " + rs1.getString("location"));
 }
 rs1.close();
 
 if (cStmt.getMoreResults()) {
    ResultSet rs2 = cStmt.getResultSet();
    while (rs2.next()) {
    System.out.println(rs2.getInt(1) + " " + rs2.getString(2) + " " + rs2.getString(3));
    }
    rs2.close();
 }
 cStmt.close();
}

I hope this article has been helpful to your Java programming.
