Does anyone know how to stop SQL server from applying exclusive table locks on mass Insert statements. I need to allow concurrent inserts into the same table using INSERT ... SELECT * FROM ...
SQL Server applies exclusive table locks that prevent this. I've tried setting LE as high as it goes but with no success. Microsoft suggest using single row inserts but this will be far too slow!

There are 2 tables which need to have data inserted into them for auditing purposes. The number of inserts per minute seems be at least 50-100. How to reduce locks during inserts.
There are 2 tables
Table1 ID - Surrogate Key/identity Column SomeColumn1 SomeColumn2 SomeColumn3 SomeColumn4_timestamp
clustered index on ID column
Table2 ID Column ..... there's a call to get id from SCOPE_IDENTITY() SomeColumn1 SomeColumn2 clustered index on ID column NC idx on SomeColum1 NC idx on SomeColum2
I have two tables for insertion in one transaction scope. Table one have 10 rows. After first table insert statement (not yet committed) if I run select on first table from other session, it holds table until my insert is committed or rolled back and from (SSMS), it display 10 rows and then wait for transaction scope till finished. My question is do I need to use no lock hint in this situation. Or there is something wrong with isolation level. One saying that in this situation table should not hols select while insert is in transaction scope.
I have a question regarding a locking scheme in MSSQL I hope you guys can help. In Sybase, I am able to specify datarow locking in DDL (ex. create table, alter table). Can I do the same in MSSQL or is there an equivalent option in CREATE TABLE statement in MSSQL? I came across a few articles in MSDN about datarow locking and it seems to me that MSSQL only allows locking through DML... Is that true? Thanks.
SQL Server 6.5 on-line help states that IRL is only effective if the table has a unique clustered index defined on the table. IF this true and if so does anyone know why.
I am trying to insert data using the select * command from one table into another, but query analyzer just seems to run and run (over one hour before I stopped it). The current activity shows a huge number of extent locks. The table itself has approx 90,000 rows. What is causing this insert not to finish, and how do I sort it?
I am a little confused over LE thresholds etc. At present the server has the following settings: LE threshold max - 10000 LE threshold min - 20 LE threshold % - 0 locks - 60000
Hi, I want to insert a record in a table having an identity column as primary key. I want to lock the table while inserting. so that no one should be able to insert, select, update, delete from the table. and once my insert is over, then will release the lock.
Can I have the code for the same. M using SQL SERVER 2005.
We have a SSIS package which loads the data from csv files to DB. It only loads the new entries ie if the row already exists in the tables than it doesn't insert it. For this we load the CSV to temp tables for respective schemas and than those are compared with base tables of respective schemas and inserted new rows. For this we use Merge statement.
I have an SSIS package doing a bulk insert from a file. Then later on I'm trying to delete that file (in a file delete task), but I'm getting an error:[File System Task] Error: An error occurred with the following error message: "The process cannot access the file 'xyz' because it is being used by another process.".I'm wondering if there isn't some way to 'tweak' the bulk insert syntax so that it doesn't lock the file?
I have implemented Remus Resanu's implementation from the Recycling Conversations article and I am experiencing locking issue when I try to insert new conversation handles to the SessionConversations table. I have copied the code in the article exactly including the activation procedure. Any ideas why I may be locking. I am thinking it is related to the HOLDLOCK hint on the table.
The sepcific line where I see locking is directly from the article:
INSERT INTO [SessionConversations] (SPID, FromService, ToService, OnContract, Handle) VALUES (...etc)
I've have a need with SQL Server 2005 (so I've no MERGE statement), I have to merge 2 tables, the target table has 10 fields, the first 4 are the clustered index and primary key, the source table has the same fields and index.Since I can't use the MERGE statement (I'm in SQL 2005) I have to make a double step operation, and INSERT and an UPDATE, I can't figure how to design the WHERE condition for the insert statement.
An insert statement was not inserting all the data into a table. Found it very strange as the other fields in the row were inserted. I ran SQL profiler and found that sql statement had all the fields in the insert statement but some of the fields were not inserted. Below is the sql statement which is created dyanmically by a asp.net C# class. The columns which are not inserted are 'totaltax' and 'totalamount' ...while the 'shipto_name' etc...were inserted.there were not errors thrown. The sql from the code cannot be shown here as it is dynamically built referencing C# class files.It works fine on another test database which uses the same dlls. The only difference i found was the difference in date formats..@totalamount=1625.62,@totaltax=125.62are not inserted into the database.Below is the statement copied from SQL profiler.exec sp_executesql N'INSERT INTO salesorder(billto_city, billto_country, billto_line1, billto_line2, billto_name,billto_postalcode, billto_stateorprovince, billto_telephone, contactid, CreatedOn, customerid, customeridtype,DeletionStateCode, discountamount, discountpercentage, ModifiedOn, name, ordernumber,pricelevelid, salesorderId, shipto_city, shipto_country,shipto_line1, shipto_line2, shipto_name, shipto_postalcode, shipto_stateorprovince,shipto_telephone, StateCode, submitdate, totalamount,totallineitemamount, totaltax ) VALUES(@billto_city, @billto_country, @billto_line1, @billto_line2,@billto_name, @billto_postalcode, @billto_stateorprovince, @billto_telephone, @contactid, @CreatedOn, @customerid,@customeridtype, @DeletionStateCode, @discountamount,@discountpercentage, @ModifiedOn, @name, @ordernumber, @pricelevelid, @salesorderId,@shipto_city, @shipto_country, @shipto_line1, @shipto_line2,@shipto_name, @shipto_postalcode, @shipto_stateorprovince, @shipto_telephone,@StateCode, @submitdate, @totalamount, @totallineitemamount, @totaltax)',N'@billto_city nvarchar(8),@billto_country nvarchar(13),@billto_line1 nvarchar(3),@billto_line2 nvarchar(4),@billto_name nvarchar(15),@billto_postalcode nvarchar(5),@billto_stateorprovince nvarchar(8),@billto_telephone nvarchar(3),@contactid uniqueidentifier,@CreatedOn datetime,@customerid uniqueidentifier,@customeridtype int,@DeletionStateCode int,@discountamount decimal(1,0),@discountpercentage decimal(1,0),@ModifiedOn datetime,@name nvarchar(33),@ordernumber nvarchar(18),@pricelevelid uniqueidentifier,@salesorderId uniqueidentifier,@shipto_city nvarchar(8),@shipto_country nvarchar(13),@shipto_line1 nvarchar(3),@shipto_line2 nvarchar(4),@shipto_name nvarchar(15),@shipto_postalcode nvarchar(5),@shipto_stateorprovince nvarchar(8),@shipto_telephone nvarchar(3),@StateCode int,@submitdate datetime,@totalamount decimal(6,2),@totallineitemamount decimal(6,2),@totaltax decimal(5,2)',@billto_city=N'New York',@billto_country=N'United States',@billto_line1=N'454',@billto_line2=N'Road',@billto_name=N'Hillary Clinton',@billto_postalcode=N'10001',@billto_stateorprovince=N'New York',@billto_telephone=N'124',@contactid='8DAFE298-3A25-42EE-B208-0B79DE653B61',@CreatedOn=''2008-04-18 13:37:12:013'',@customerid='8DAFE298-3A25-42EE-B208-0B79DE653B61',@customeridtype=2,@DeletionStateCode=0,@discountamount=0,@discountpercentage=0,@ModifiedOn=''2008-04-18 13:37:12:013'',@name=N'E-Commerce Order (Before billing)',@ordernumber=N'BRKV-CC-OKRW5764YS',@pricelevelid='B74DB28B-AA8F-DC11-B289-000423B63B71',@salesorderId='9CD0E11A-5A6D-4584-BC3E-4292EBA6ED24',@shipto_city=N'New York',@shipto_country=N'United States',@shipto_line1=N'454',@shipto_line2=N'Road',@shipto_name=N'Hillary Clinton',@shipto_postalcode=N'10001',@shipto_stateorprovince=N'New York',@shipto_telephone=N'124',@StateCode=0,@submitdate=''2008-04-18 14:37:10:140'',@totalamount=1625.62,@totallineitemamount=1500.00,@totaltax=125.62
Hello I have a problem with setting relations properly when inserting data using adonet. Already have searched for a solutions, still not finding a mistake... Here's the sql management studio diagram :
and that causes (at line 67):"The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Question_SurveyTemplate". The conflict occurred in database "ankietyzacja", table "dbo.SurveyTemplate", column 'id'. The statement has been terminated. at System.Data.Common.DbDataAdapter.UpdatedRowStatusErrors(RowUpdatedEventArgs rowUpdatedEvent, BatchCommandInfo[] batchCommands, Int32 commandCount) at System.Data.Common.DbDataAdapter.UpdatedRowStatus(RowUpdatedEventArgs rowUpdatedEvent, BatchCommandInfo[] batchCommands, Int32 commandCount) at System.Data.Common.DbDataAdapter.Update(DataRow[] dataRows, DataTableMapping tableMapping) at System.Data.Common.DbDataAdapter.UpdateFromDataTable(DataTable dataTable, DataTableMapping tableMapping) at System.Data.Common.DbDataAdapter.Update(DataSet dataSet, String srcTable) at AnkietyzacjaWebService.Service1.createSurveyTemplate(Object[] o) in J:\PL\PAI\AnkietyzacjaWebService\AnkietyzacjaWebServicece\Service1.asmx.cs:line 397"
Could You please tell me what am I missing here ? Thanks a lot.
This problem is being seen on SQL 2005 SP2 + cumulative update 4
I am currently successfully using the output clause of an insert statement to return the identity values for inserted rows into a table variable
I now need to add an "instead of insert" trigger to the table that is the subject of the insert.
As soon as I add the "instead of insert" trigger, the output clause on the insert statement does not return any data - although the insert completes successfully. As a result I am not able to obtain the identities of the inserted rows
Note that @@identity would return the correct value in the test repro below - but this is not a viable option as the table in question will be merge replicated and @@identity will return the identity value of a replication metadata table rather than the identity of the row inserted into my_table
Note also that in the test repro, the "instead of insert" trigger actually does nothing apart from the default insert, but the real world trigger has additional code.
To run the repro below - select each of the sections below in turn and execute them 1) Create the table 2) Create the trigger 3) Do the insert - note that table variable contains a row with column value zero - it should contain the @@identity value 4) Drop the trigger 5) Re-run the insert from 3) - note that table variable is now correctly populated with the @@identity value in the row
I need the behaviour to be correct when the trigger is present
GO /************************************************ 2) - Create the trigger ************************************************/ CREATE TRIGGER [dbo].[trig_my_table__instead_insert] ON [dbo].[my_table] INSTEAD OF INSERT AS BEGIN
INSERT INTO my_table ( forename, surname) SELECT forename, surname FROM inserted
END
/************************************************ 3) - Do the insert ************************************************/
INSERT INTO my_table ( forename , surname ) OUTPUT inserted.my_table_id INTO @my_insert VALUES( @forename , @surname )
select @@identity -- expect this value in @my_insert table select * from @my_insert -- OK value without trigger - zero with trigger
/************************************************ 4) - Drop the trigger ************************************************/
drop trigger [dbo].[trig_my_table__instead_insert] go
/************************************************ 5) - Re-run insert from 3) ************************************************/ -- @my_insert now contains row expected with identity of inserted row -- i.e. OK
Hi All, I've looked through the forum hoping I'm not the only one with this issue but alas, I have found nothing so I'm hoping someone out there will give me some assistance. My problem is the case statement in my Insert Statement. My overall goal is to insert records from one table to another. But I need to be able to assign a specific value to the incoming data and thought the case statement would be the best way of doing it. I must be doing something wrong but I can't seem to see it.
Here is my code: Insert into myTblA (TblA_ID, mycasefield = case when mycasefield = 1 then 99861 when mycasefield = 2 then 99862 when mycasefield = 3 then 99863 when mycasefield = 4 then 99864 when mycasefield = 5 then 99865 when mycasefield = 6 then 99866 when mycasefield = 7 then 99867 when mycasefield = 8 then 99868 when mycasefield = 9 then 99855 when mycasefield = 10 then 99839 end, alt_min, alt_max, longitude, latitude ( Select MTB.LocationID MTB.model_ID MTB.elevation, --alt min null, --alt max MTB.longitude, --longitude MTB.latitude --latitude from MyTblB MTB );
The error I'm getting is: Incorrect syntax near '='.
I have tried various versions of the case statement based on examples I have found but nothing works. I would greatly appreciate any assistance with this one. I've been smacking my head against the wall for awhile trying to find a solution.
I'm quite stuck with this:I have an import table called ReferenceMatchingImport which containsdata that has been sucked from a data submission. The contents ofthis table have to be imported into another table ExternalReferencewhich has various foreign keys.This is simple but one of these keys says that the value inExternalReference.CompanyRef must be in the CompanyReference table.Of course if this is an initial import then it will not be so as partof my script I must insert a new row into CompanyReference andpopulate ExternalReference.CompanyRef with the identity column of thistable.I thought a good idea would be to use an SP which inserts a new rowand returns @@Identity as the value to insert. However this doesn'twork as far as I can tell. Is there a approved way to perform thissort of opperation? My code is below.Thanks.ALTER PROCEDURE SP00ReferenceMatchingImportAS/*Just some integrity checking going on here*/INSERT ExternalReference(ExternalSourceRef,AssetGroupRef,CompanyUnitRef,EntityTypeCode,CompanyRef, --this is the unknown ref which is returned by the spExternalReferenceTypeCode,ExternalReferenceCompanyReferenceMapTypeCode,StartDate,EndDate,LastUpdateBy,LastUpdateDate)SELECT rmi.ExternalDataSourcePropertyRef,rmi.AssetGroup,rmi.CompanyUnit,rmi.EntityType,SP01InsertIPDReference rmi.EntityType, --here I'm trying to run thesp so that I can use the return value as the insert value1,1,GETDATE(),GETDATE(),'RefMatch',GETDATE()FROM ReferenceMatchingImport rmiWHERE rmi.ExternalDataSourcePropertyRef NOT IN (SELECT ExternalSourceRefFROM ExternalReference)

I am having difficulties with my first hand coded insert statement. The record inserts BUT the first item VALUE is selected for all the drop down lists ( 3 of them are optional) I have Prerenders on the page to insert a null value at the top of the list. For the dropdown that is mandatory it only enter first item. Thats without specifying type. As soon as I specify type I get - Input string not in correct format - doesn't actually tell me which one!!!!!! All char types match the database.
Here is my insert:

Hi All, I am trying to insert data into table1 by getting data from table2, table3 and looking whether the data is already not exist in table1. Here is my code... insert into table1 (first_name, last_name, user_login, email, organization_name) values (select ru.firstname, ru.lastname, ru.UserID, ru.EmailAddress, ru.BusinessName from table2 ru, table3 wepsUsers where ru.id = wepsUsers.user_id and not exists (select user_login from table1 where user_login = ru.UserID))
When I excute the code, I am getting the following error..... Server: Msg 156, Level 15, State 1, Line 3Incorrect syntax near the keyword 'select'.Server: Msg 170, Level 15, State 1, Line 7Line 7: Incorrect syntax near ')'. But, If execute the following code.... select ru.firstname, ru.lastname, ru.UserID, ru.EmailAddress, ru.BusinessName from table2 ru, table3 wepsUsers where ru.id = wepsUsers.user_id and not exists (select user_login from table1 where user_login = ru.UserID).... I am able to see the values.
Can any one shade on my code? and please let me know, where I am doing wrong. I am appreciate your help.
Is there anyway that we can use insert into statement to insert data into the first row of a table, or initialize the column with the new inserted data.
I am trying to do an insert in a particular View...one of the field has got an 'Apostrophe'.(Ex: SQl Server's). When i do this i get an error. the system does not allow me to insert.... is there any way i can do an Insert with that...???
How do I 1.) take two seperate columns and combine the data 2.) take that combined data and populate a third column.
Here is an example of what I've been trying to do:
Insert INTO Table_1 (Column1) Select Column2 + Column3 From Table_1
I continue to get this error message:
Server: Msg 515, Level 16, State 2, Line 1 Cannot insert the value NULL into column 'Column_2', table 'DB1.dbo.Table_1'; column does not allow nulls. INSERT fails. The statement has been terminated.
If some one could please give me a general script that could do this I would appreciate it. I'm new to using SQL and I'm a little bit lost.
