We run a web hosting company and we use SQL Server, it happens that we put up several new SQL databases a month. Invariably, the developer will forget to put the new database in 'Simple' recovery model. If you leave a database in 'Full' mode and only run regular backups, the transaction logs won't truncate and the drive will fill up.
That's what happened today (sigh), so I searched and found a script on http://richardteachout.com/Blog/tabid/165/EntryID/64/Default.aspx. I have made a small mod and I am reprinting the script here so that I don't lose it.
USE master
GO
-- Declare a variable to store the value [database name] returned by FETCH.
DECLARE @dbname sysname, @cmd varchar(1000)
-- Declare a cursor to iterate through the list of databases
DECLARE db_recovery_cursor CURSOR FOR
SELECT name from sysdatabases
-- Open the cursor
OPEN db_recovery_cursor
-- Perform the first fetch and store the value in a variable.
FETCH NEXT FROM db_recovery_cursor INTO @dbname
-- loop through cursor until no more records fetched
WHILE @@FETCH_STATUS = 0
BEGIN
IF (SELECT DATABASEPROPERTYEX(@dbname,'RECOVERY')) <> 'SIMPLE' and @dbName <> 'tempdb' BEGIN
-- create the alter database command for each database
SET @cmd = 'ALTER DATABASE ' + @dbname + ' SET RECOVERY SIMPLE'
-- alter each dataabase setting the recovery model to FULL
EXEC(@cmd)
PRINT @dbname
end
FETCH NEXT FROM db_recovery_cursor INTO @dbname
END
-- close the cursor and deallocate memory used by cursor
CLOSE db_recovery_cursor
DEALLOCATE db_recovery_cursor
