SQL upgrade from MSDE: UpgradeAdvisor returned -1 .

admin — Wed, 12 May 2010 06:47:40 +0000

Cause:

The error occurs because of a problem with BPACMD.EXE attempting to load BPAClient.dll. While upgrading the instance of SQL Server the setup looks for the BPAClient.dll and it fails as it is not able to find it at C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\BPA.

Solution :
Copy the BPAClient.dll file from the following location C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\BPA\bin to C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\BPA.

SQL: attached a mdf without the log file.

Missing ldf file

Solution
You can attach a database without the logfile by attaching, then clicking the logfile location, and click the remove button. After you click OK a new logfile will be created for your database

sQL: SQL 2000 truncate logs using DBCC

admin — Sat, 23 Jan 2010 00:10:37 +0000

DBCC statememnts act as Database Console commands. You can use the below listed queries, sprcifically the DBCC ones to shrink your transaction log.

– To GET the name of the log and data files
select name from dbo.sysfiles

– SEE the active transactions as well as the File ID
dbcc loginfo(‘db_Name’)

– Mark transactions inactive so that they can be truncated later
– Suppose file ID is 2

DBCC SHRINKFILE (2)
– Backup the log file and truncate the inactive entries
BACKUP LOG [db_name] WITH TRUNCATE_ONLY
– Run Shrinkfile again for maintainence.
DBCC SHRINKFILE (2)

You can create a stored procedure out of the last 3 statements and schedule it as a job on your server than can run overnight and ensure that the transaction log file size does not get out of hand.

SQL 2008 : Delete all tables in a db

admin — Fri, 27 Nov 2009 21:10:22 +0000

Reference

EXEC sp_MSforeachtable @command1 = “DELETE FROM ?”

EXEC sp_MSforeachtable @command1 = “TRUNCATE TABLE ?”

——
You won’t be able to run TRUNCATE against all tables if you have foreign keys references

Here is one way to circumvent that

– First disable referential integrity
EXEC sp_MSForEachTable ‘ALTER TABLE ? NOCHECK CONSTRAINT ALL’
GO

EXEC sp_MSForEachTable ‘
IF OBJECTPROPERTY(object_id(”?”), ”TableHasForeignRef”) = 1
DELETE FROM ?
else
TRUNCATE TABLE ?
‘
GO

– Now enable referential integrity again
EXEC sp_MSForEachTable ‘ALTER TABLE ? CHECK CONSTRAINT ALL’
GO

SQL: HRESULT 0×80070008

If you are sure your SQL query is correct trying having your webhost restart the SQL server engine. This error could mean the SQL process does not have enough memory to process your request..

other error:

SQL: The DTS Wizard for importing and exporting

admin — Sun, 26 Jul 2009 19:26:01 +0000

We found some article relating to the DTS Wizard which is a good tool to use for exporting and importing db structures.

so far we have not found the toolkit for SQL 2008 and assume the 2005 version works with 2008. If you have confirmed this please feel free to contact me and correct this information.

You can download the DTS Tool via the 2005 toolkit which can be downloaded from Microsoft.

SQL/ASP: The timeout period elapsed prior to completion

admin — Sat, 16 May 2009 22:54:56 +0000

Error:
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

Try adding a Connect Timeout in the web.config

The Connect Timeout attribute of a connection string determines how long a SqlConnection Object runs before it stops attempting to connect to a server.

SQL: drop current connections

admin — Sun, 10 May 2009 02:00:41 +0000

You can view the current connections by executing the system proc
sp_who2 , if you wish to kill the connection type: kill and the pid number

or use

ALTER DATABASE ‘DATABASE_NAME’ SET SINGLE_USER WITH ROLLBACK_IMMEDIATE.

SQL: Save (Not Permitted) Dialog Box

admin — Sat, 21 Mar 2009 18:41:18 +0000

OMG :

Error :
The Save (Not Permitted) dialog box warns you that saving changes is not permitted because the changes you have made require the listed tables to be dropped and re-created.

The following actions might require a table to be re-created:

Adding a new column to the middle of the table
Dropping a column
Changing column nullability
Changing the order of the columns
Changing the data type of a column

Reference: MSDN

The user posted a good point on M$ website. what are you suppose to do with the data once the column has been dropped.

Answer: export the data out and back in duh…. But this is a stupid security setting.. bad Microsoft….

***updated information ********
no words can explain how I am feeling right now .
******************************
Solution:
Within studio management 2008 , you will need to click on tools > options > designers tab > uncheck prevent saving changes that require table re-creation
