Batch Operations Of SQL Command.
Jun 6, 2007
Hi,
Im trying to write a class that compiles a list of SQLCommands and then executes them all at once. Im trying to reduce the amount of calls to the database.
Im also trying just to update the fields which have changed so I cannot use Stored Procedures as that would mean writing way too many stored procedures for every permutation on every table in my database.
So Ive decided to build sql commands and then execute them all with one call to the database. When I print the commandtext property of the sqlcommand to the page whilst debugging It shows something like insert into XXX (f1,f2) values (@v1,@v2). Is there any way to see the final sql string, with the @v1 variables replaced by the actual values in the parameters I have added to the sql command?
Im building the commands by creating a new sqlCommand. Then I set the commandtext to "insert into XXX (f1,f2) values (@v1,@v2)". Then I Add Parameters to the sqlCommand. My Parameters count is showing the correct value.
I want to be sure now that when I go to send these commands to the database as part of one long string that it will work.
Thanks,
C

HI all,
I'm trying to have a SProc that will initialize a database for me. This db is in development (I'm primarily writing SSIS packages, atm), and I constantly need to truncate the tables, then re-add a dummy/unknown row (PK/Identity value = 1). Of course, I need triggers not to fire (got that part working), and FK constraints to be bypassed temporarily -- that's the problem.
Here's where I'm at:
----------------------------------------------------------------------------------
CREATE PROCEDURE [dbo].[_InitializeDB]
AS
SET NOCOUNT ON
DECLARE @name varchar(255)
DECLARE @sql nvarchar(255)
DECLARE tables CURSOR FOR SELECT [name] FROM [sysobjects] WHERE [type]='U' AND [name]<>'sysdiagrams'
OPEN tables
FETCH NEXT FROM tables INTO @name
WHILE @@FETCH_STATUS=0
BEGIN
SET @sql = 'ALTER TABLE ['+ @name + '] NOCHECK CONSTRAINT ALL'
EXEC sp_executeSQL @sql
SET @sql = 'DISABLE TRIGGER ALL ON [' + @name + ']'
EXEC sp_executeSQL @sql
SET @sql = 'TRUNCATE TABLE [' + @name + ']'
EXEC sp_executesql @sql
BEGIN TRY
SET @sql = 'INSERT INTO [' + @name + '] (Active) VALUES (0)'
EXEC sp_executeSQL @sql
END TRY
BEGIN CATCH
PRINT @sql + ':'
PRINT ERROR_MESSAGE()
END CATCH
SET @sql = 'ENABLE TRIGGER ALL ON [' + @name + ']'
EXEC sp_executeSQL @sql
SET @sql = 'ALTER TABLE ['+ @name + '] CHECK CONSTRAINT ALL'
EXEC sp_executeSQL @sql
FETCH NEXT FROM tables INTO @name
END
CLOSE tables
DEALLOCATE tables
----------------------------------------------------------------------------------
Running this Sproc produces (for the first ref'd table):
Msg 4712, Level 16, State 1, Line 1
Cannot truncate table 'Person' because it is being referenced by a FOREIGN KEY constraint.

Does anyone know where Enterprise Manager (MSSQL 2000) gets the "Last TSQL Command Batch:" information from that shows when you display the properties for a process listed under current activity/Process Info for a server.
This could be useful for a bespoke system monitoring utility in my system.

DB - MS SQL 6.5
I am looking at EM - Current Activity - Detailed Activity. When I double-click on a user I see their "Last TSQL Command Batch". Unfortunately, the command that some are running is larger that the screen accommodates! Is there any way to see the complete "Last TSQL Command Batch"????
Thanks You.

Good afternoon-
Can a batch file that resides on another server be executed from a different machine? I have a batch file that resides on a server that I would like to run using SQL 2005 Integration Services. Is there anything I can do that would allow me to remotely execute this batch file and have it run in that environment.
BATCH FILE:
cd C:Trandev
otrun -at OTRecogn.att -DINPUT_FILE=%1 -tl 1 -cs dv -lg mylog -I
C:Trandev represents the remote environment
I have tried mapping the remote machine to a network drive on my local machine and using that drive to execute the batch file in an Execute Process Task, but it does not work.
SSIS:
I have a FOR EACH loop grabbing files and writing fileName to a variable that is passed to the Process Task as an argument through an expression(%1 in the batch file above). The Working Directory is a mapped network drive. The Executable is also a network drive plus batch file name.
Any help would be appreciated.
My computer is a HP Compaq dc7100, 512mb RAM, WindowsXP

Hi all,I just start using SQL Server for my project. I have some questionsrelated to set operations. Suppose I have two tables, Table A andTable B, as following.TableA TableB======= =======--------------- ---------------| ID | DATA | | ID | DATA |--------------- ---------------| 1 | Val-01 | | 1 | Val-01 || 2 | Val-01 | | 2 | Val-02 || 3 | Val-02 | | 3 | Val-02 || 4 | Val-03 | | 4 | Val-03 || 5 | Val-04 | ---------------| 6 | Val-05 |---------------In DB2, I can write SQL statements as followingSQL 1:===========================SELECT DATA FROM TableAEXCEPTSELECT DATA FROM TableBAnd the result will beVal-04Val-05===========================SQL 2:===========================SELECT DATA FROM TableAEXCEPT ALLSELECT DATA FROM TableBAnd the result will beVal-01Val-04Val-05===========================1. How can I handle the EXCEPT (ALL) operator in SQL Server?2. Are there equivalent SQL queries for the above SQL queries?Thank youErwin Leonardi

I'm still a newbie with MS SQL DB. I was asked to perform some tasks within 3 days at maximum as follows:
1- Refine unique names from over than 80,000 students' names (Firstname, Middlename and Lastname) into a unique table so that we take all those name and translate them from local language to English through data entry employees (a dictionary).
2- Replace local names by English names into a new columns.
3- Creating a procedure that auto generates aliases based on Firstname, Middlename and Lastname as follows:
Assume the name John Edward Smith is found 5 times between 80,000 students, to create a unique ID do the following:
1- FirstnameLastnameint (JohnS).
2- FirstnameinLastname (JSmith).
3- FirstnameLastname (JohnSmith).
4- Firstnameint.Lastname (J.Smith).
5- Firstname.Middlenameint.Lastname (John.E.Smith).
Another precedure also needed:
We have 4 divisions at the establishment, needed to symoblize each division by a letter followed by ( - ) sign as follows:
1- If division = X , generate: x-ID
2- If division = Y, generate: y-ID
3- If divison = Z, generate: z-ID
4- If division =S, generate: s-ID
Can you please provide me with such a procedure to perform this in details?
Thank you

Hello,
I would like to know if there is a way to disable logging within SQL. (SQL7)
I set all of the obvious options (select into/bulk copy; truncate on checkpoint...) -- and not using SQL Servers conditions set in books online.
Here is the situation:
We have a VB app that updates about 14million records on a monthly basis. The commands are INSERT, UPDATE.. (no select into OR write text) There is no way to use this app that I know using BCP, or bulk insert since we are updating and not simply importing?
So now when this process runs, first the Tempdb fills(problem 1). I shut down SQL and re-initalized the TEmpdb. The data "update" should take ~3 days. Initial run shows the Tempdb filling, then the thread halts. Basically, the application copies records from a user defined "staging" database into a second user database. The second db's transaction log is growing considerable (say 6GB and growing after only a day) (problem2). I am concerned that after resolving the Tempdb from filling (unrestricted size set, and I know Tempdb automatically truncates on checkpoint..) but then we still face the issue to the db that the data is updated will fill out of control!
Ideally, I would like to set a db option that disables logging during this UPDATE statement, in other words operate with no integrety. We backup before so a restore should take care of things in the event. I think this will also aid in performance.
Thoughts on update nonlogged operations if any?
Thanks in advance.
Jason

hello,
I need to push data from a temporary table into a master table in sql server database(Both tables are in the same database).
I need to follow these conditions.
tables used:
1. temporary table: Temp
2. master table: Master
for every record or row in Temp
check if exists(Temp.field1)in Master.Field1 then
update Master with this row.
else Insert into Master this row.
I performed a research through the net, and found various suggestions. like usage of cursors, usage of while loops etc.
I have to use nearly 50,000 to 60, 000 rows minimum or even more.
Time complexity is also to be considered
I request all who visit this thread to place any possible solutions/suggestions how shall i make this task.
I thank all in advance

I'm new to SQL Server and relatively new to database design and I have a specific problem I'm trying to resolve. I have a collection of records in a table (let's call them 'tasks') which represent some list of things that needs to be completed. Each task has an associated datetime on which this action is to commence, and my applications is responsible for executing these tasks. My first instinct is to regularly poll the 'tasks' table to determine if there are any tasks which have not been processed and are past their schedule start datetime. But, I'm wondering if there is some sort of database feature that would recognize that a task's starttime has arrived, and could somehow communicate this to my application without my application having to constantly poll the database. Thanks.

Every time I mention cursors, I hear a lot of people pointing out how you shouldn't use cursors and how set based operations are much faster.
However, procedural code offers the big advantage that I can embed status/progress type commands into a cursor loop and get accurate data on progress and ETA.
If I execute a single huge UPDATE/INSERT, I am at the whim and mercy of SQL Server. Seemingly simple statements often run for 50 hours+ and I have no clue how far along it is or anything remotely close to an ETA. Often, that is absolutely inacceptable to have mission criticial hardware to be churning through a process for DAYS without the slightest idea if it is actually making progress or not.
Is there any way to get progress/status on such an UPDATE/INSERT command?

Hi,
I'm trying to get data from several databses of different kinds (Sql Server and Oracle) and from different servers - is that possible ?
If not - is there any way to copy some data from one database to another - like tables and their content (or partial content) ?
I tried to use "select name from <database name>..sysobjects where xtype = 'U'" but I get security error.

I am using the following batch file to execute a script that creates a db and all its objects in the local sql express:
sqlcmd -S (local)SQLExpress -i C:CreateDB.sql
This works fine, but I'm wondering if there's an easy way to put the script in the batch file, so users don't have to worry about putting the script in the C drive. I tried getting rid of the i parameter and pasting the script from the sql file into the batch file, but it didn't work.

For example,

I can't find corresponding MOM rule for it.

I'm trying to optimize a few batch import procedures we use in our processes.
It currently works like this:
1) Cursor loop cycles through all data to be imported from IMPORT table
2) For every record there is an attempted insert to PROD table in a TRY-CATCH check to see whether the record would pass all the primary key and foreign key constrains in PROD table
3) Only those that pass the TRY-CATCH check gets imported into PROD table
4) Every row gets logged into a separate LOG table, either with a comment like "Import OK" or "Error: foreign key violation in field 'my_id'"
The thing is, the procedure runs fine when I'm importing several thousands of records, but when it comes to hundreds of thousands, the speed becomes an issue, as I currently get 20 records per second and slowing...
There is no other code in that procedure, no queries. Just the Cursor cycle and the try-catch check.
PS: I'm using MS SQL Server 2005.

Currently studying for 70-229.I'm trying to understand how security for users is managed in SQLServer. I've been using SQL Server for a few years now, but withoutinvestigating the bits that "just work".So, here's the scenario. This is more or less how I create all myapplications (which these days are all ASP.NET).I have a database called "TESTDB" (original, huh?)Now, I want to create a method for users to access this database, so Iopen EM, locate and expand the node for the server containing thedatabase, and open the "Security" node. Click on the "Logins" leaf,and in the pane right-click and select "New Login.."On the "General" tab I enter "TESTDBLOGIN" as the Name.Select "SQL Server Authentication", and put in a password.In the drop-down list of databases select "TESTDBLOGIN"Ignoring the "Server Roles" tab, I go to the "Database Access" tab andscroll down until I can see the "TESTDB" database. Check the "Permit"checkbox, and lo!, the "Database Roles for TESTDB" list is populated,with "public" already ticked. I check the "db_owner" box, and press"OK". It asks me to confirm the password, and once that's done there'sa new login called TESTDBLOGIN. What's more in "Users" leaf in the"TESTDB" database node there's a new user called "TESTDBLOGIN".All well and good. I can now create a connection using this login anddo more or less what I want in the TESTDB database.But.If I click the "Users" leaf in the "TESTDB" node, there are two users -"dbo" and "TESTDBLOGIN". If I right-click the "TESTDBLOGIN" user, Ican see that it has Database Role Memberships for the "public" and the"db_owner" roles. But if I examine the permissions on these two roles(by selecting the row, and then pressing the "Permissions" button) Ifind that there are permissions set for EITHER role - all the checkboxes are blank!So, how is it that I can do SELECT, UPDATE, INSERT and DELETEoperations via this login/user?Sorry it all took so long - I just wanted to get it right.ThanksEdward--The reading group's reading group:http://www.bookgroup.org.uk

We use Reporting Services in native mode in our environment and have several data-driven subscriptions on reports. Somehow not all of the subscriptions can be executed, this seems totaly random and doesn't always apply to the same report/schedule. In the event viewer, I can see the error message : "Scheduled operations cannot be created. SQL Server Agent is not running" ....
But the Agent is in running state and there are no logs that the Agent has stopped or started again. A few minutes later, everything looks okay again and the rest of the scheduled subscriptions are executed.
This doesn't happen every day but 3 or 4 times a week. The following version of SQL Server is installed :
Microsoft SQL Server 2008 R2 (SP2) - 10.50.4295.0 (X64) Oct 18 2013 19:22:52 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 6.2 <X64> (Build 9200: ).
What causes these problems or where to look to determine the cause of this error?

Hi Teachies,
I am using SQL Server Standard Edition with good HardWare configuration.
In one of table i am inserting around 25 millions records and that takes time around more than 3 hrs.
same thing is happening while fetching records from that table.
this database contains only single file group i.e primary
and that table contains .. Clustered as well as non clustered index.
it doesnot have any Triggers.
How do i increase this performance.
Paritioning of table cannot be use in SQL Server Standard Edition.
Or Dropping all non clustered index before insert operation will improve my performance.
Please suggest me.
Thanks

I actually am just looking for some supporting documentation on some facets of SQL Server.As far as I have always known, when anyone does a READ from a SQL Server database (SELCT * from <TABLE>), SQL Server does not create a log record...since there's no data or database structure being modified. A colleague is under the impression READ's are logged operations.
