Transact SQL :: Not Allowed To Write Delete Statements In A Function?

Jun 25, 2015

We are not allowed to write delete statement in a function. It will give the below error.

"Invalid use of a side-effecting operator 'DELETE' within a function."

We will get the same error for truncate/drop statements.

What is the reason behind this error?

Transact SQL :: Reducing Deadlocks From Conflicting Delete Statements

Jun 15, 2015

I am working on an app that getting quite a few deadlocks due to delete statements.  I have turned on the sql trace flags and pulled the offending delete statements out of the ERRORLOG and trying to mesh those up with the indexes defined on the table, etc. looking to see if there is anything that can be done strictly from the db side (no app code change) to reduce/eliminate these deadlocks.  I have ran some tests/played around with RCSI and even disabling lock escalation but neither have improved my results.

What I have done is to search the errorlog file for DELETE FROM Tablename, output those matching lines, then sort of normalize the literal values to # or XYZ, open in Notepad++, removed trailing whitespace + dups and sort to come up with these results for the unique list of offending T-SQL statements (a LOT easier to read in text editor so sending screen cap.

Transact SQL :: Declaring Cursor Causing Select Statements Included Within A Function Cannot Return Data To Client?

Sep 29, 2015

I cannot find the problem with this function.

ALTER function [Event].[DetermineTrackTime](@TrialID varchar(max)) returns int as
begin
Declare @ret int;
Declare @EnterVolumeTime int;
Declare @ExitVolumeTime int;
Declare @StartTrackTime int;

[code]....

I am getting the following error on line 75:

Select statements included within a function cannot return data to a client.

This is happening when declaring TrackUpdateCursor

The compiler has no problem with the VolumeTimesCursor. What is causing this and what can I do about it?

Are IN Statements Allowed In CASEs..?

and that is giving me "incorrect syntax near 'in'" ??

Are Multiple Statements Allowed For CommandText?

Dec 4, 2007

Hi,

I'm wondering if SqlCommand.CommandText could be set with multiple statements when CommandType=Text. anyone knows it?

I'm sure storedprocedure is the right way to go. I'm curious if this is one thing that only sp can do.

Thx

T-SQL (SS2K8) :: Searching For Allowed Characters From Table Using Function?

Aug 10, 2015

I want to create a function that searches for allowed characters within a table range (that contains the allowed characters) and replace any characters outside this range with a space.

For example -

'Bill123?', 'Jones12.z-'
'John&12/', 'QWERT123&4'

Wanted results – the single quotes are there to show the space for the replaced characters.

'Bill123 '
'Jones12.z '
'John&12 '
'QWERT123 4'

Example SQL data

CREATE TABLE [Common].[AllowedCharacters] (
[Character] [varchar](1) NOT NULL,
[Replacement] [varchar](10) NULL,
[AlwaysInclude] [bit] NOT NULL)
GO
SET ANSI_PADDING OFF

[code]....

The function will wrap around the column names and I know it can be done without a table validate the characters but it must be done this way.

Mar 7, 2007



Question to those who may have had this same error- it seems that I am not able to delete some of the reports that I have created. This just started happening recently and according to our system admin nothing has changed as far as permissions are concernced. We installed SP2 the other day and I was wondering if this could have anything to do with the error message below

DateTime.Now, An Allowed Null Field, And My Insert Function From My Dataset

Jun 6, 2008

I have a table adapter for one of my SQL2005 tables, and in two different fields I accept a date time. Now 99% of the times, new rows to this table will be filled out using DateTIme.Now(), as a Time Stamp is what I'm going for.
 
Here is the line of code in question...cops_current_data_adapter.Insert(ProductOrder, Convert.ToInt16(Session["StationId"].ToString()),
PartNumber, DateTime.Now, DateTime.Now, Convert.ToInt16(qty), 0);
 The second DateTime.Now is the one that can be null, and it's throwing a formatting error everytime I try and drop it in there. It's a FormatException, and there's not much more to the example except unhelpful tips like be careful when conveting a string to a dateTime, which I'm not doing. Needless to say for the code to compile, and then throw a Format error at runtime is a bit frustraiting.
 Any suggestions would be most appreciated

Should I Add Lock Statements To My Database Write Querys

Jun 5, 2008

Hello,Could some clarify for me? I’ve been told that I should add  lock statements  to my database write querys (update, delete, insert). I’m not sure If it’s necessary though. The only documentation I’ve found so far is how to implement a lock statement with threading but I’m not using the threading namespace. What best practice and how would I implement this without threading or should I be using threading?Thanks in advance!

Delete Statements Without Log Filling Up

Aug 13, 2002

I have a database that I am splitting the data using odd account numbers and even account numbers. The odd acct numbers in one database and the even in the other database.

This database is very large. The problem is when I run the delete statements
it is going to fill up the log files. Can I turn on the "Simple" mode on the database while I am deleteing the data. Will this cause a problem? Then can I turn back on the 'Full' mode when I have finished?

Has anyone ever done this and so how did it work. Or better yet is it possible?

Thanks,

Delete Statements In Partitioned Views

Dec 10, 2002

Hi, I am using sql2000 ent edition. I have a partitioned view based on 8 tables. My selects and inserts are fine. But, when I run a delete on the view based on a query on the paritioned column, I get a "Transaction (Process ID 149) was deadlocked and has been chosen as a victim".
I looked at the query plan and it was showing a parallel query on all the underlying tables. So, I put the Option(maxdop 1), using only one processor and the delete worked fine.

Does anybody know why? is parallel query create deadlocks? is there any known problems with deletes on partitioned views?
same question for updates. I think I have the same problem for updates.

Any help will be useful.
thanks!!

Combining DELETE And JOIN Statements

Nov 20, 2006

In SQL Server 2000/2005 (not CE) I can use the following T-SQL statement to delete orphaned rows from a table:

DELETE GroupsMembers FROM GroupsMembers LEFT OUTER JOIN Groups ON GroupsMembers.GroupID = Groups.ID WHERE Groups.ID IS NULL

SQL Server CE does not seem to support combining the JOIN statement with the DELETE statement. Is this correct? If yes, is there any alternative statement that could be used to accomplish the same thing?

Additional INSERT, UPDATE, And DELETE Statements Disabled.

Apr 21, 2007

Hi, I just want you to know that I am very young in ASP.NET world so please bear with me.I have been looking for an answer to my problem, but unfortunately I couldn’t find one.  So I created a user here on www.asp.net just for making this post.
Before I continue I just want to apologies if there is another post where this question is already answered.
 

 
Please watch this Print Screen I just took: ? http://www.bewarmaronsi.com/Capture.JPG “
As you can see the “INSERT, UPDATE, and DELETE Statements? are disabled, and that’s exactly my problem. I tried with an MS access database and it works perfect, but when I use a MS SQL database this field gets disabled for some reason.
The MDF file is located in the App_data folder and is called ASPNETDB.
And when I try to add custom SQL statements, it gives me Syntax error near “=?. Something like that.  I bought the Total Training Set1 package and it works perfect in their examples.
I just want to thank you for reading my post and I hope that you got some useful information for me.
By the way, I’, from Sweden so you have to excuse me if my English is rusty.
Thanks!
PS: Can it be that I’m running windows Vista?

Do Not Replicate DELETE Statements Still Replicates Deletes To Subscribers

Dec 4, 2006

I previously asked What does "Do not replicate DELETE statements" do? to make sure I was correct on my thinking of what "Do not replicate DELETE statements" does. And after finding out it does what I would like it to do, create an archive db, I've tried several testing scenarios to see if it would work. So far I have been unable to not replicate delete statements. I'm not sure if I'm not setting a property right or what and any guidance would be appreciated.

Here is what I've done.

Created a blank db to be used as a subscriber and created a test db with some random data in a table.
Setup a New Publication on the db with the random data as "Transactional Publication"
Selected the following articles and properties in the publication

Tables

DELETE Delivery Format = Do not replicate DELETE statements
Views

Default Values
Stored Procedures

Default Values
User Functions

Default Values
Selected the default options for the rest of the New Publication Wizard steps and clicked finish.
Created a Pull Subscription on the new publication that I just created.
Let it initialize.
Then did a select count(*) query on the test table on the publication (18k+ rows) and subscriber (18k+ rows)
Then did a delete t-sql from the test table on the publication.
Then did a select count(*) query on the test table on the publication (0 rows) and subscriber (0 rows).

Now shouldn't it not delete the records on the subscription db?

SqlDataSource: Can't Gen INSERT/UPDATE/DELETE Statements; Using 2.0 Membership Aspnetdb

Jul 20, 2006

Hi,I'm new to ASP.NET and having a problem configuring the SqlDataSource control.  I am using the standard ASP.NET 2.0 "aspnetdb" database to manage user accounts.  The problem is this:When using the wizard to configure my SqlDataSource control, the option to auto-generate the Insert/Update/Delete SQL statements are grayed out.   I've searched this forum and found that this can be a symptom of no primary keys in the tables.  However, there are primary keys (UserId), which is the default schema as generated by asp.net (aspnet_regsql.exe).  When I use the wizard, I make the following choices:How would you like to retrieve data from your database?-> Select "Specify columns from a table or view"-> Select the "vw_aspnet_MembershipUsers" view from the "Name:" drop-down list-> Select "UserId", "Email", "UserName"  from "Columns:"After this, still no option to auto-generate I/U/D statements.  Any thoughts on why this isn't working???

Transact SQL :: How To Use More Than 10 Case Statements

May 12, 2015

I need to breakdown some information with just initials (sometimes 2, sometimes 3 if the initials are already used) SQL Server throws the error of:

Msg 125, Level 15, State 4, Line 1

Case expressions may only be nested to level 10.

What should I alter, or how should I write this query so I can use all of the needed case statements? (their are actually about 24 when statements, but this is just to get a working example to display)

Select
case
when employee_name Like 'Jorge Jones' Then 'JJ'

Transact SQL :: Error - Maximum Row Size Exceeds Allowed Maximum Of 8060 Bytes

Sep 12, 2015

I have some code I build 2 weeks ago which I’ve been running daily but it’s suddenly stopped working with the following error.

“The table "tbl_Intraday_Tmp" has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes. INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit” When I google this there seems to be a related to tables with vast numbers of columns.

My table tbl_Intraday_tmp is relatively small. It has 7 columns. 1 of varchar(5), 3 of decimal(9,3) and 2 of decimal(18,0). The bit I’m puzzled with is it was working and stopped.

I don’t recall changing anything but I wouldn’t rule that out. I ‘ve inspected the source files and I don’t believe they have changed either.

DECLARE              
@FileName varchar(50),
@Path varchar(50),
@SqlCmd varchar(1000)
= '',
@ASXCode varchar(5),
@Offset decimal(18,0),
