# INSERT INTO SELECT Statement

### The SQL INSERT INTO SELECT Statement

The INSERT INTO SELECT statement copies data from one table and inserts it into another table.

* INSERT INTO SELECT requires that data types in source and target tables match
* The existing records in the target table are unaffected

#### INSERT INTO SELECT Syntax

Copy all columns from one table to another table:

```sql
INSERT INTO table2
SELECT * FROM table1
WHERE condition;
```

Copy only some columns from one table into another table:

```sql
INSERT INTO table2 (column1, column2, column3, ...)
SELECT column1, column2, column3, ...
FROM table1
WHERE condition;
```

SQL INSERT INTO SELECT Examples

The following SQL statement copies "Suppliers" into "Customers" (the columns that are not filled with data, will contain NULL):

```sql
INSERT INTO Customers (CustomerName, City, Country)
SELECT SupplierName, City, Country FROM Suppliers;
```

The following SQL statement copies "Suppliers" into "Customers" (fill all columns):

```sql
INSERT INTO Customers (CustomerName, ContactNam
SELECT SupplierName, ContactName, 
```

The following SQL statement copies only the German suppliers into "Customers":

```sql
INSERT INTO Customers (CustomerName, City, Country)
SELECT SupplierName, City, Country FROM Suppliers
WHERE Country='Germany';
```
