I have a table into which the inserts will be done by multiple users at the same time;
The table has a primary key, non clustered, on unique id; each insert will have unique id, which is a seqence generated number, so they are always different for different transactions.
Is this possible to set the settings of sql server in such a way, that these inserts are done at the same time i.e. during insert by one user that table is not locked so that other inserts can take place at the same time as well?
Hi,I would have used the aspnet membership tool to auto-create all the ASP.NET membership tables. However, the hosting company don't allow remote connections which meant I had to create the tables by hand, scripting the tables using script to CREATE using management studio.However, I noticed one of the tables has data without any users: aspnet_SchemaVersions, which causes an error when trying to log onto my site.The fix is to make sure the table has the 4-5 rows of data in it (which is missing off the live server). Its just a few rows of data, but I want to script the inserts for each row so I don't have to type them in using myLittleAdmin (the host's web version of management studio). Can anyone point me in the right direction?
I want to insert a row for a Global user in Table 'A' whenever ADO.Net code inserts a Local user row into same table. I recommended using a trigger to implement this functionality, but the DBA was against it, saying that stored proecedures should be used, since triggers are unreliable and slow down the system by placing unecessary locks on the table. Is this true OR the DBA is saying something wrong? My thinking is that Microsoft will never include triggers if they are unreliable and the DBA is just wanting to offload the extra DBA task of triggers to the programmer so that a stored procedure is getting called, so he has less headache on his hands.Thanks
Hello all. I've got a problem with really slow INSERTs on one (and only one) of the tables in a database. For example, using SQL Management Studio, it takes 4 minutes and 48 seconds to insert 25 rows. There are only about 8 columns in the table and only about 1500 records. All the other tables in the database are very fast for inserts.
Another odd thing uniquely associated with INSERTs on this table: prior to inserting the 25 new rows of data, SQL Management Studio tells me that it inserted 463 rows of data which I know did not happen. Here's the INSERT statement:
INSERT INTO FieldOps(StudySiteID , QA_StructureID , Notes , PersonID) SELECT DISTINCT StudySiteKey , QA_StructureKey , SampleComments1 , '25' FROM ScriptOutput_Nitrate WHERE (ScriptOutput_Nitrate.StudySiteKey IS NOT NULL)
and SQL Management Studio (eventually) says: (463 row(s) affected) (463 row(s) affected)
(25 row(s) affected)
The table has an index on the primary key (INT data type with auto increment). I tried running the following code to fix things but it made no difference:
USE [master] GO ALTER DATABASE [FieldData] SET SINGLE_USER WITH ROLLBACK IMMEDIATE GO
use FieldData GO DBCC CHECKTABLE ('FieldOps', REPAIR_REBUILD) With ALL_ERRORMSGS GO
USE [master] GO ALTER DATABASE [FieldData] SET MULTI_USER WITH ROLLBACK IMMEDIATE GO
I'm guessing that the problem might be related to the index (??). I don't know... Does anyone here have a suggestion as to what I should do to fix this problem.
Dear All, I developed an application years ago where I have to insert records in multiple table from asp.net page during registration process with one button click. I have seperate Insert statements and then i have to select Identity column value and insert into another table as a foriegn key and so on. I want to run all these SQL insert in one statement or Stored procedure. becuase currently, if one of insert statemetn fails, I have no way to roll back previous inserts and start over again.
Any advice or sample T-SQL Where I can insert in Table A, and then read the identity from Table A and insert in Table B, in one single Transaction, so if it fails at end of Transaction, i want to roll back the all the inserts and updates in table(s).
I've been looking online and cannot find any help / resources with this so I brought it here :D I'm looking for help in creating a Cursor (this will be inside a SP) that will loop through the records of a "Table" (Temporary or Retrieved) and for each row that is looped through I can use it's values to do inserts against a few other tables. Any resources / help would be great! I work best by example.
I have data in an old database I would like to capture for my new system but I dont have the original insert scripts. Is there a tool (in SQL Server 2000 or thirdparty) that will help me export the data as SQL inserts?
I am working on an application to analyse down time on a production line system. The system has about 40 rows inserted per minute. The inserts are coming from about 10 different stations.
I need to a analyse the downtime between each insert from each station. The plan is to copy the data to another database on a different server so as not to affect the live system that is being updated by the production line.
However the initial requirement was to do this at night while the production line was down but now they want the data to be updated every 3 hours which means performing this huge query while the production line is bombarding the DB with inserts.
I am wondering what is the best way of doing this. Is there any way I can limit the abount of processor this proceedure will take.
I need to create a table that only allows records to be inserted or deleted. Once the record has been created it can only be deleted. Is there anyway to configure a table in this manner?

I have a situation here. Please advice me on this.
I have a master table and a child table. They have a PK and FK relationship. The master table has an identity column with auto increment set to true. This map as a FK in the child table. My questions are:
Can I have a single form to insert a new record into master and child table at the same time?This has to be accomplished without stored procedures. Can it be done?Is it possible to do this with a single insert query? If yes, can it be done with sql data source or dataset or tableadapters’?Please point me towards appropriate link for doing so.
I am using vwde2008 and created db and table. i want to create a stored procedure that will insert values. I am bit lost on how write this. this is my table info table = BusinessInfo Columns = BusinessID, BusinessName, BusinessAddress how can i create a stored procedure ?
I am looking for pros and cons for the following scenarios:
When a table contains a unique key constraint is it viable to always do an insert and immediately check the @@ERROR value and if @@ERROR states a duplicate key exception then perform an update statement?
Another possible solution would be to always check if the key exists and then do the insert / update based upon that result. This method will always require two steps.
Hopefully someone can at least point me in the right direction for moreresearch (e.g.: correct terminology). My only previous experience was justdumping data into a database using ODBC, and that was some years ago so nowmostly forgotten.I need to write an NT Service/Application (in C/C++) that will be gettingdata sent to it via SQL Server 2000. The data will arrive in my SQL Server(read-only access), via replication of tables from another remote SQLServer.My application needs know when new row are inserted, or updated so it can toread this data (needs to be quick/timely so hopefully no polling) to theninterface with other remote proprietary systems.T.I.A.PS: If you can recommend appropriate books on SQL Server 2000 that wouldalso be useful.
Hello,Can someone point me to getting the total number of inserts and updates on a tableover a period of time?I just want to measure the insert and update activity on the tables.Thanks.- Vish
I have a SSIS package that imports data into a staging table from an excel sheet (This works fine). From the staging tabler i want it to insert the values into my members table, take that unique indentityID that gets created and insert the other values into other tables for that member that was just created.
In the staging table, i have all the values for a single member. But the structure of the database needs all the values inserted into seperate tables. There is no conditions ID in my members table, so the member first has to be created and from there i need to use the newly created member's MemberID and insert the conditions into a seperate table using the MemberID
I have created some sample data that can be used. I think i have an idea of how to do it, but i'm not totally sure if it will work that way, i have however included it in the sample data.

I am trying to create a trigger on a table. Let's call it table ABC. Table looks like this:
SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[ABC]( [id] [uniqueidentifier] NOT NULL,
[Code] ....
When someone updates a row on table ABC, I want to insert the original values along with the current date and time getdate() into table ABCD with the current date and time into the updateDate field as defined below:
SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[ABCD]( [id] [uniqueidentifier] NOT NULL,
[Code] .....
The trigger I've currently written looks like this:
/****** Object: Trigger [dbo].[ABC_trigger] Script Date: 4/10/2015 1:32:33 PM ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TRIGGER [dbo].[ABC_trigger] ON [dbo].[ABC]
[Code] ...
This trigger works, but it inserts all of the rows every time. My question is how can I get the trigger to just insert the last row updated?
I can't sort by uniqueidentifier in descending as those can be random.
CREATE TABLE [Sales].[Test_inmem] ( [c1] [int] NOT NULL, [c2] [nvarchar](20) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, [ModifiedDate] [datetime2](7) NOT NULL CONSTRAINT [IMDF_Test_ModifiedDate] DEFAULT (sysdatetime()),
[Code] ....
I have to generate 1000000 random records into it. I tried various ways to insert records, but not being a developer could not do it. I hope to make the C1 as a serial number, C2 can be anything, C3 I want to be the timestamp.
Assuming I should be using values from temp inserted to insure correct record... Need help coding IF...THEN INSERT statements in following After TRIGGER:

I need a script that inserts the data of an excel sheet into a table. If something already exists it should leave it, unless it's edited in the excel sheet and so on and so on. This proces has to go through a stored procedure... ...But how?
I want to ship 500,000 aged transactions each night to an archive table and delete them from their source table in one or more logical units of work (LUW). Each row is approx 60 bytes and there is only one non clustered index on the source table presently.
I'm trying to weigh the pros and cons of 3 alternatives. One of them would basically insert the non-aged rows into tempdb, ship the aged records, truncate the table and then insert the tempdb records back into their source all in the same LUW.
For this alternative, I'd at least like to turn off logging when the records get inserted into tempdb as I dont see any value in logging that part of the activity. Is this possible?
I have one partition table "tablea" with partition key dateentry on yearly basis and table have four partition with name y2013,y2014,y2013,y2015 with one partition schema .

I'm copying date from a sql server 2000 table to a sql server 2008 R2 table using a Linked Server.I need to be sure the remote table is correct before processing it.I first delete all the remote table contents and after that, I insert into remote_table from local_tableWhat happens if the communication is interrupted during the insert?I mean, Can I be sure all records were copied just checking if record count > 0 ?
I want to insert lots of data into two tables. For this I want to use table valued parameters and a stored procedure. So, what is the better way for best performance? Using two stored procedures or a single procedure with two parameters? How does SQL Server consume the data if I use a single procedure with two parameters. Is it really streaming the data? I mean, is SQL Server already starting to insert the first rows as soon as it gets it even if the client is still sending more and more rows and than the same with the next table? e.g. I have a procedure like this:
CREATE PROCEDURE [dbo].[usp_UpdateElements] ( @tvpElementsToInsert As [dbo].[tvpElements] Readonly, @tvpElementValuesToInsert As [dbo].[tvpElementValues] Readonly) AS Begin Insert Into Elements Select * From @tvpElementsToInsert; Insert Into ElementValues Select * From @tvpElementValuesToInsert; End
I use below trigger to email me when a database is created or dropped.
CREATE TRIGGER [DDL_CREATE_DATABASE_EVENT] ON ALL SERVER FOR CREATE_DATABASE AS DECLARE @bd VARCHAR(MAX) DECLARE @tsql VARCHAR(MAX) SET @tsql = EVENTDATA().value
[Code] ...
Is there a way we can get notification when a table is created or altered or dropped ?
I have a question relating to the ANSI_PADDING setting on some existing tables in a SQL Server 2008 R2 database I am working with. When I generated the tables originally I basically programmatically created them by building CREATE scripts within my code. Since I did not explicitly set ANSI_PADDING to ON all these tables they seem to have been created with ANSI_PADDING as OFF. Some of these tables, which I now need to add columns to, contain varchar(n) and varbinary(n) columns.
When I try to alter the tables through Management Studio, SQL Server gives me a warning: "One or more tables have ANSI_PADDING 'off' and will be recreated with ANSI_PADDING 'on'" - this seems to be generated by the ALTER statement which by default sets ANSI_PADDING to ON. Another iteration of the same warning - "Columns have different ANSI_PADDING settings. New columns will be created with ANSI_PADDING 'on'".
From what I read regarding ANSI_PADDING it seems ON is definitely the way to go. I just need to know if changing the value may result in any of the existing data in the table to be changed or may have any other unintended side effect, as this may cause problems for me.
