<p>I need to empty an LDF file before sending to a colleague.  How do I force SQL Server to truncate the log?</p>

In management studio:
Don't do this on a live environment, but to ensure you shrink your dev db as much as you can:
Right-click the database, choose
```
Properties
```
, then
```
Options
```
.
Make sure "Recovery model" is set to "Simple", not "Full"
Click OK
Right-click the database again, choose
```
Tasks
```
->
```
Shrink
```
->
```
Files
```
Change file type to "Log"
Click OK.
Alternatively, the SQL to do it:
```
```
ALTER DATABASE mydatabase SET RECOVERY SIMPLE
 DBCC SHRINKFILE (mydatabase_Log, 1)
```
```
