# SQL JOIN Example: Using Vs. ON This is the Difference

Here are the differences between **Using **and **ON in Jo[in SQL query](https://srinimf.com/2013/09/06/db2-multi-row-insert-into-a-table/)**. Here are two sample tables – **Customer_table** and **Order_table. You can see sample SQL to join these tables using both ** USING and ON.

Here the joining method is INNER JOIN ( joining is based on matching column of both the tables).

## How to use **Using **to in SQL query to Join tables

Here join condition is customer_number.

```
SELECT
  Customer_Number
 ,Customer_Name
 ,Order_Number
 ,Order_Total
FROM   Customer_Table
INNER JOIN
        Order_Table
Using (Customer_Number) ;
```

Here the ‘using, clause works as ‘on’. So the joining happens based on the column name given in the using clause.

## How to use **ON** in SQL query to Join Tables

```
SELECT
  Customer_Number
 ,Customer_Name
 ,Order_Number
 ,Order_Total
FROM   Customer_Table a
INNER JOIN
        Order_Table b
ON a.Customer_Number = b.Customer_Number;
```

Here the ‘ON’ clause is used to join tables.

### Differences Between USING and ON

In the Using, you can give multiple columns in simple way:

```
using(col1, col2, col3)

In the case of ON:

ON a.col1=b.col1
AND a.col2=b.col2;
```
