I was searching for Set ParseOnly On support from a managed application. This directive prohibits being used from within a stored procedure.
At the same time, while searching somewhere I referenced about a SQL Parser assembly and a sample codesnippet like vbSQLParser.
I was searching through my system assemblies and also on the Internet but could not make out which assembly or component does this source from? Can someone throw some hint or if it is a download URL from Microsoft or elsewhere, a download URL would be appreciated.

Looks like I am getting it.
Microsoft.SqlServer.Common assembly seems to have a lot of utility towards this objective. Trying to research on it and harness its benefits.

Dears,
I'm using MS SQL Server 2005 and i'm inserting a time value which is ArrivalTime in column and at the end of the trip i insert another time value in another column which is leavingTime
And I want to save the diffrence between the two times in another Column TripTime
so the value in TripTime should be LeavingTime - ArrivalTime
How can this be done.
Thanks

To get the difference between 2 dates use the DATEDIFF function.
But there's no need to store the TripTime since you've already stored Leaving and Arrival. If you store it you are going to risk the data getting out of sync if there are any changes. Instead, whenever you need to get the tip time, just make a call to DATEDIFF using leaving and arrival times.

Well, it depends. If you want to be able to search on the trip time - find all trips where the trip time was longer than/shorter than x amount, then you might want to build a computed column and index the table on that computed column, although indexes on computed columns have a set of prerequisite option values which IIRC aren't the defaults, so you have to be a bit careful about setting the options to ensure that the index gets used.
If you can't guarantee the options then perhaps a trigger to compute and store this value would be appropriate.

Delete can be rolled back but Truncate cannot be rolled back.
Begin Transaction
Delete Del_Details
Rollback
and i'm getting my deleted records
but still when i use ....
Begin Transaction
Truncate Table Del_Details
Rollback
This command is also giving me my deleted records..
So where is the difference between Delete and Truncate in respect of Rollback.......Plz explain
|
|
|
|
|
in Sql Server 2000 may be true for other DB's but i have not looked into it, the delete command cheks for data integrety(sp?) and actually removes each record from the tree if there are no FK problems. Truncate basically just moves the pointer from the bottom of the tree to the top and forgets that there was ever any data in there, essientially removes any reference to where that was in memory and starts over. Therefore Rollback cant work beacuse there is nothing to rollback, there is no longer any reference to whatever was in that table. I dont know for sure how they store the data, but using the analogy of a bTree helps when i explain it to people at work. hopefully i explained that right.

BOL: The DELETE statement removes rows one at a time and records an entry in the transaction log for each deleted row. TRUNCATE TABLE removes the data by deallocating the data pages used to store the table's data, and only the page deallocations are recorded in the transaction log.
If you are in a transaction, it probably does not reuse the pages until COMMIT. Also, truncate can not be run when foreign keys are present.

 When you asked this question before (^) several of us gave you the fullest explanation possible. If you don't believe us the try google or something, because no matter how many times you ask the real answer is going to be the same.

Hi all,
Am trying to upsize certain tables from MSAccess database to SQL database.I have a preexisting database with tables which are vacant in SQL.While i try to upsize the database tables from MSAccess 2003 to SQL server am getting an error.I tried to upsize three tables out of which one was upsized fine with all data imported with out errors(was not having foreign key relations).But the other two are shooting errors and not upsizing .
The error looks like "
"Server Error 3726:"Couldnot drop object 'tablname' because it is referenced by a Foreign key constraint."
I tried to remove all the foreign key connections in SQL tables and still getting the same error.
Since am doing this for the first time,am unsure what exactly is the way to go?
Any help will be welcome.
Many Thanks,

The following code is giving me the described error. I have included my debug trace also.
Apparently if the "LIKE" text is not found at all is causing this behavior.
How do I get around it?
Thanks for your help.

m_FDRecordset->Open(AFX_DB_USE_DEFAULT_TYPE,
"SELECT * FROM [Log] WHERE [Callsign] LIKE '" + text + "%'",
CRecordset::readOnly );
CString strSQL = m_FDRecordset->GetSQL( );
TRACE("\n SQL %s ",strSQL);
Debug trace
SQL SELECT * FROM `Log` WHERE `Callsign` LIKE 'AA1A%' Error: attempted to position cursor on empty recordset.

};

Since it's tracing the SQL I would assume it's the statement after the TRACE which is causing the exception. You probably need to check IsBOF and IsEOF to ensure that some rows were returned before trying to reference any fields.

Thanks - I guess I was "half a bubble off" looking at the wrong statement and assuming it was the Open recordset failing.
I guess I should have checked the return from Open!
Thanks again.

Hi,
I am using sql bulk copy to insert into table from txt file. The following code is is being used for row terminator but it does not work. it works with '\n'. But it should be work with Unix system as well.
@BQUERY AS nVARCHAR(250)
SET @BQUERY = 'BULK INSERT tblCustomer
FROM ''' + @FILEPATH + '''
WITH
(
FIRSTROW = 2,
FIELDTERMINATOR = '','',
ROWTERMINATOR = ''\x0A''
)'
EXECUTE SP_EXECUTESQL @BQUERY

Unix row terminators are not the same as windows. Windows uses \r\n, unix only uses \r
Hope this helps

Try doing a hex dump of your data and see exactly what character(s) delimit the lines. You can use multiple characters in your format file as record delimiters, so you should be OK.

I have read the file using StreamReader it has given some info about file. File is encoded with UTF-8 with code page 65001. It shows \n as line terminator which is not work with SQL bulk Insert.
