xp_cmdshell error: ‘C:\Program’ is not recognized as an internal or external command,

\ by

Apparently in my 64-bit environment I can’t execute the following command.

DECLARE @vcCmd VARCHAR(8000)
SELECT @vcCmd = '"C:\Program Files\Winzip\WZZIP.exe" -es -a "E:\DATA\test.zip" "E:\DATA\test.dat"'
EXEC   master..xp_cmdshell @vcCmd = @vcCmd
/*
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.
*/

The solution is I can execute other DOS commands, so let’s concatenate them.

DECLARE @vcCmd VARCHAR(8000)
SELECT @vcCmd = 'C: && CD "C:\Program Files\Winzip\" && WZZIP.exe -es -a "E:\DATA\test.zip" "E:\DATA\test1.dat"'
EXEC   master..xp_cmdshell @vcCmd = @vcCmd

Check SQL jobs which have run during daylight saving’s change hours.

\ by

What has run, during the last month, on Sunday’s between 1:59 AM and 3?
Use the to check on daylight saving’s jobs which might be missed.


SELECT MAX(master_admin.dbo.fn_INTtoDateTime(run_date, run_time) ),
j.name
FROM msdb.dbo.sysjobhistory h WITH (NOLOCK)
JOIN msdb.dbo.sysjobs j WITH (NOLOCK)
ON j.job_id = h.job_id
WHERE datename(dw, convert(varchar(10),run_date, 112) ) = 'Sunday'
AND run_time BETWEEN 015900 AND 030000
AND step_id = 0
AND run_date >= CONVERT(VARCHAR(8), DATEADD(day, -31, GETDATE()), 112)
GROUP BY j.name ,DATENAME(weekday, CONVERT(VARCHAR(10), run_date, 112))
ORDER BY
name

This uses one of my functions. fn_INTtoDateTime

IF @vcDate = '00000000'
SET @vcDate = LEFT(REPLACE(REPLACE(REPLACE(CONVERT(VARCHAR(23), CAST(0 AS SMALLDATETIME), 121),

SQL Server – Performance – Log file

\ by

Logfile hardware recommendations. By Tripp.

4) Not only should you try to isolate the transaction log to its own physical disk but you should make sure that the logical/physical disk configuration is as efficient as possible. 
   Try to use an isolated RAID 1 mirroring set if you don't need significant capacity. If you need a greater capacity OR you want better performance, 
   consider a combination of RAID 0 and RAID 1 (either RAID 0 + 1 or RAID 1 + 0). 
While RAID 0 + 1 can often offer better performance, RAID 1 + 0 offers better reliability.

SQL Msg 15138: The database principal owns a schema in the database, and cannot be dropped.

Here’s my script to fix this error. This occurs when I restore a database to another server and want to remove the source server users.


DECLARE @vcSchemaName VARCHAR(128);
SET @vcSchemaName = 'schema name goes here'
SELECT s.name,
 'ALTER AUTHORIZATION ON SCHEMA::[' + @vcSchemaName + '] TO dbo;'
FROM sys.schemas s
WHERE s.principal_id = USER_ID(@vcSchemaName

Operation is not valid due to the current state of the object

This error occurs for me when I loop through a list of $CurrentServers. The solution was to add Out-Host to the end of the output line.
