More Details


PDOModel – Database abstraction and helper PHP class that helps to do insert, update, delete, select operation using PDO without writing any queries and with much lesser code. It supports Mysql, Postgres,SQlite and SQL Server database.

Version 1.3 – PDOModel now supports SQL Server along with PGSQL, SQLite and Mysql.

PDOModel provides a complete solution to perform CRUD operations on three different types of database (Mysql, Postgres and Sqlite). It provides various helper functions to export data directly to csv,excel,xml,pdf,html and many more useful functions.

Example of how to write SQL select query using PDOModel

$pdomodel = new PDOModel(); //create object of the PDOModel class $pdomodel->connect("localhost", "root", "", "pdocrud");//connect to database $result = $pdomodel->select("emp"); //select * from `emp`

That’s it, you need to write just 2-3 line of code. You can write very complex queries using PDOModel functions

PDOModel supports three type of database, Mysql, Postgres and Sqlite.

PDOModel script allows you to export data directly in various database formats.


$pdomodel = new PDOModel();//create object $pdomodel->connect("localhost", "root", "", "pdocrud");//connect to database - three different database type available /* INSERT , UPDATE AND DELETE OPERATION */ $pdomodel->insert("emp", array("firstName" => "John", "lastName" => "Jonathan", "gender" => "male")); $pdomodel->where("orderId", 7); $pdomodel->update("order", array("orderNumber"=>"44", "customerName"=>"BKG", "address"=>"140 shakti nagar")); $pdomodel->where("orderId", 7); $pdomodel->delete("order"); /* SELECT */ $result = $pdomodel->select("emp"); /* WHERE, AND, OR, BETWEEN, GROUP BY, ORDER BY, LIKE , HAVING */ $pdomodel->where("orderNumber", "5", "!="); $pdomodel->openBrackets ="("; $pdomodel->where("city", "Indore", "="); $pdomodel->andOrOperator="OR"; $pdomodel->closedBrackets =")"; $pdomodel->groupByCols = array("orderId"); $pdomodel->orderByCols = array("orderId desc", "state asc"); $pdomodel->havingCondtion = array("sum(orderId)>2"); $pdomodel->limit = "0,5"; $pdomodel->where("empId", array(36,37), "BETWEEN"); $pdomodel->where("firstName", '%P%', "LIKE"); $pdomodel->where("empId", array(36,37,39,40), "IN"); /* subquery/inner query */ $pdomodel->subQuery("select empId from emp where empId=?","empId",array(34)); /* where subquery */ $pdomodel->where_subquery("orderId", "select orderId from `order` where orderId=?", "IN",array(10)); /*rename, trucate, drop table, column name, primary key, tablefield info*/ $pdomodel->truncateTable("wp_postmeta"); $pdomodel->renameTable("states","state"); $pdomodel->dropTable("empleave"); $records = $pdomodel->columnNames("order"); $records = $pdomodel->primaryKey("order"); $records = $pdomodel->tableFieldInfo("order"); /*execute sql*/ $result = $pdomodel->executeQuery("select * from emp where empId = ?", array(39));
