# TransactionSetSavepoint

Sets a savepoint in the current transaction.

This savepoint can then be a rollback point when executing a rollback via `transactionRollback( "mySavepointName" )`.

## Method Signature

```
TransactionSetSavepoint(savepoint=[string])
```

### Arguments

| Argument    | Type     | Required | Description               | Default |
| ----------- | -------- | -------- | ------------------------- | ------- |
| `savepoint` | `string` | `true`   | Specify a savepoint name. |         |

## Examples

#### Using TransactionSetSavepoint with TransactionRollback

Here's a simple example of using multiple savepoints within a transaction:

```java
transaction {
    queryExecute( "INSERT INTO vehicles (id,make) VALUES (8, 'Ford' )", {}, { datasource : "carDB" } );
    transactionSetSavepoint( 'insert' );

    queryExecute( "UPDATE developers SET name = 'Chevrolet' WHERE id=8", {}, { datasource : "carDB" } );
    transactionSetSavepoint( 'update' );

    // more stuff ...
    transactionRollback( 'insert' );
}
```

In this example, the UPDATE will be rolled back while the INSERT statement will remain. Remember that in `transactionRollback()`, the savepoint is not the name of a single savepoint to roll back, but the name of the savepoint to rollback TO.

### Roll back to a specified savepoint

This example runs multiple queries with a savepoint for each, and rolls back to the 'useradded' savepoint if the last query fails.

```java
bx:transaction {
	// insert user
	transactionSetSavepoint( "useradded" );
	try {
	}
	// another query
	 catch (any e) {
		transactionRollback();
	}
}

```
