Truncating All Transaction Logs in SQL Server

DROP TABLE #CommandQueue

CREATE TABLE #CommandQueue
(
    ID INT IDENTITY ( 1, 1 )
    , SqlStatement VARCHAR(1000)
)

INSERT INTO #CommandQueue
(
    SqlStatement
)
SELECT
    'BACKUP LOG [' + name + '] WITH TRUNCATE_ONLY'
FROM
    sys.databases
WHERE
    name NOT IN ( 'master', 'model', 'msdb', 'tempdb' )

DECLARE @id INT

SELECT @id = MIN(ID)
FROM #CommandQueue

WHILE @id IS NOT NULL
BEGIN
    DECLARE @sqlStatement VARCHAR(1000)
    
    SELECT
        @sqlStatement = SqlStatement
    FROM
        #CommandQueue
    WHERE
        ID = @id

    PRINT 'Executing ''' + @sqlStatement + '''...'

    EXEC (@sqlStatement)

    DELETE FROM #CommandQueue
    WHERE ID = @id

    SELECT @id = MIN(ID)
    FROM #CommandQueue
END

Counting Rows in All Database Tables in SQL Server

SELECT
    sysobjects.Name
    , sysindexes.Rows
FROM
    sysobjects
    INNER JOIN sysindexes
    ON sysobjects.id = sysindexes.id
WHERE
    type = 'U'
    AND sysindexes.IndId < 2
ORDER BY
