Truncate WSS_Logging DB

One day you try to access your SharePoint site and notice that site does not load and instead throws an error. You investigate the error and find out that it has something to do with the WSS_Logging database. It is a common problem and I have blogged about it before as well. I just cannot find that blog post anymore (smiles). I have changed three or four blogs over the last couple of years. Anyway, getting back to the point. If you are facing this issue, truncate your WSS_Logging DB and you should be good to go.

1.       Open your SQL UI. Right click WSS_Logging DB and go to Reports > Disk Usage OR Reports > Standard Reports > Disk Usage.

Figure 1: Disk Usage

2.       In the disk usage report, expand the second node to see current disk usage. It should be full.

 

3.       Right-click WSS_Logging B and select “New Query” and paste the following script in the window and then hit F5 to execute it. NOTE: This script was copied from the following link:

Script:

·         DECLARE @TableName AS VARCHAR(MAX) DECLARE table_cursor CURSOR FOR SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE = 'BASE TABLE' AND TABLE_NAME LIKE '%_Partition%' OPEN table_cursor FETCH NEXT FROM table_cursor INTO @TableName WHILE @@FETCH_STATUS = 0 BEGIN DECLARE @SQLText AS NVARCHAR(4000) SET @SQLText = 'TRUNCATE TABLE ' + @TableName EXEC sp_executeSQL @SQLText FETCH NEXT FROM table_cursor INTO @TableName END CLOSE table_cursor DEALLOCATE table_cursor

 

Different people have written different scripts to truncate the table. This one is a tested solution and works perfectly.

4.       After executing the query, go back to the disk usage report and now you should see that the database is empty. Open your SharePoint site and it should work.
