I have to create one table and attach the trigger to the server given by the user. Assuming I have all sorts of permissions, how can I do this using CLR.
I tried this using data base project in c# and deploying it manually, it worked successfully but I am not able to get how can I provide this at run time to the user.
If I write one assembly on the client side for the same than how to run it on the back end (i.e., SQL Server).
I have created a trigger on a table for delete operation. I want to fire the trigger against each row deletion. When I applay a query that delete 5 rows, the trigger should execute five times, that is, some work to do for each row.
How can I handle this? Is there any keyword to use when create the trigger?
Very new to SQL Server - using Microsoft SQL Server Management Studio, I'm trying to create a Trigger but I get an error saying that the table doesn't exist or is invalid -- "Object 'dbo.tblPropertyValue' does not exist or is invalid for this operation". The table does exist. Following is the trigger (I replaced the actual code w/ a simple PRINT statement):
CREATE TRIGGER [dbo].[tr_PropValChange] ON [dbo].[tblPropertyValue] FOR UPDATE AS BEGIN PRINT 'Hello' END GO
I'm able to create a stored procedure that accesses that table. The database (MyDb) is running on my laptop (computer name=MyComputer) and owned by my windows account (MyComputerBill). All db tables are prefixed with 'dbo.'. I connect to Management Studio using the sa id. We're using SQL Server 2005 (Product Version: 9.00.1406.00, Product Level: RTM, Edition: Developer Edition).
Is there a way to trigger the execution of a procedure when a database is created ? We're using this 3rd party system in which you only specify the database server. Whenever the users create a new "Storage Area", the system actually creates a new database.
I need to handle backups for that system so I want to create a procedure that will generate a backup device and backup jobs automatically whenever a database is created.
I will also need 2 procedures to handle database renaming and deletion. I searched around but can't find a way to trigger the execution of my procedures.
I need a trigger to set the creation date of a new record in the database... I tried the following, but it changed all records, not just the new one...
CREATE TRIGGER trgCreationDate ON [dbo].tabCustomerLookup FOR INSERT AS BEGIN UPDATE tabCustomerLookup SET CreationDate = getdate() END
We have created a DDL trigger on SQL server 2005 database for DB audit purpose. Following is the script used for trigger creation
USE [master] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[ChangeLog](
[Code] ....
After the DDL trigger creation. Application team started reporting following error while executing a stored procedure.

I have a trigger set on TABLE1 so that any update to this column should set off trigger to write to the AUDIT log table, it works fine otherwise but not the very first time when table1 has null in the column. if i comment out
and i.req_fname <> d.req_fname from the where clause then it works fine the first time too. Seems like null value of the column is messing things up
Any thoughts?
Here is my t-sql
Insert into dbo.AUDIT (audit_req, audit_new_value, audit_field, audit_user)
select i.req_guid, i.req_fname, 'req_fname', IsNull(i.req_last_update_user,@default_user) as username from inserted i, deleted d
First time poster here, basically I have a second year university module on database design and for our coursework we have to model and create a database. One of the questions asks us to create a table that has a constraint on how many rows it can contain. I now that this is possible in some other databases, however I haven't seen a constraint that I could use on create table to limit the number of rows.. Does anyone now if this is possible?
Hi,I'm trying to create some tables dynamically based on the content of another table in the same database. I found a post that does what I want to do, but I can't get my code (that is similar to the post) to work.Given below is my code: 1 DECLARE @deptCode varchar(50), @numberOfDept int, @tableName varchar(MAX), @columnName varchar(MAX) 2 DECLARE @lengthDeptCode int, @lengthTableName int, @lengthColumnName int 3 4 SELECT @numberOfDept = COUNT(DISTINCT DeptCode) 5 FROM tbl_Department; 6 7 WHILE (@numberOfDept >=0) 8 BEGIN 9 SELECT @deptCode = DeptCode, @lengthDeptCode = LEN(DeptCode) 10 FROM tbl_Department; 11 12 SET @tableName = 'tbl_ProjectNumber'+@deptCode 13 SET @lengthTableName = LEN(@tableName) 14 SET @columnName = 'ProjectNumber'+@deptCode 15 SET @lengthColumnName = LEN(@columnName) 16 17 CREATE TABLE CAST(@tableName as char(@lengthTableName)) 18 ( 19 CAST(@columnName as char(@lengthColumnName)) int IDENTITY(1,1) NOT NULL 20 ) 21 22 SET @numberOfDept = @numberOfDept - 1 23 END This is actually my first time using SQL programatically so I'm guessing there are alot of problems with it. I just don't know what exactly. The error I get is:Msg 102, Level 15, State 1, Line 18Incorrect syntax near '@tableName'. Thanks.
Hi there,I am trying to generate tables names on the fly depending on another table. So i am creating a local variable containing the table names as required. I am storing the tables in a local variable called@TABLENAME VARCHAR(16)and when i say SELECT * FROM @TABLENAMEit is giving me an error and I think I cannot declare @TABLENAME as a table variable because I do not want to create a temp table of sorts.I hope I am clear.thanks,Murthy here
Hi All, DECLARE @MyTableVar table( EmpID nvarchar(10) ) select login_id from cpm into @MyTableVar Above syntax is not working.... Actually i want to table variable and store the result returned by stored procedure. How to do that... Thanks and reagards A
I'm working on building my database tables, and I've ran into a bit of a situation.I have one table called 'Entities' that will hold information about people, places, and events. I would like to have the user be able to add other properties to these entities ad hoc.For example, a person might have a birthdate they want to record. So I was going to setup a DateProperties table that would have be setup something like this:DatePropertyIDEntityIDName (this would be 'Birthdate' in this situation)Value (the DateTime value)In that same way, I would also want users to be able to add something like Population to the places. So I was going to setup a NumberProperties table that would have something like this:DatePropertyIDEntityIDNameValueI noticed the structures for the table is basically the same; the only thing that is changing is the Data Type for the Value. I was thinking there has to be an easier/better way to do this sort of thing, perhaps all in a single table. I'm still trying to learn all the latest stuff from .NET 3.5. I was hoping to use LINQ to SQL, but I am willing to try anything.Any suggestions?
Hello friendsI want to have a trigger for creating table on dialy basis.for e.g. I have a table say Data and on each day a new table is created like Data24Oct05 and so on. please help for writing the trigger for the same.thanks
Warning: The table 'test' has been created but its maximum row size (11864) exceeds the maximum number of bytes per row (8060). INSERT or UPDATE of a row in this table will fail if the resulting row length exceeds 8060 bytes.
I've got a problem with table creation in stored procedures (SQL Server 2000). We've got an application where the user login only has rights to execute stored procedures. The problem is that a stored proc is dynamically creating a table and so the owner of that table is being assigned to whatever login the application is using instead of dbo. It's causing numerous issues. Is there any way that this can be avoided or changed without granting the user sa privileges?
I am starting to create a new database table based on an existing dbtable. My existing table has a list of ID's and a date range for each ID.
For example: TableSource ID Start DateTime End datetime Y10012 01-12-12 13:00:00 01-19-12 13:00:00
So for this ID, I need my SQL statement to read this table, then create a new table and insert a new row for every second starting from the start date to the end date. I have several id's that span a week at a time. So I am expecting millions and millions of records once I am done.
Then once it completes reading S1001, it moves on to the next ID and appends it to the table. The date ranges are different for each ID- so it can't be hard coded.
Can you create a table on one line and then update it on the next i.e. in the same query.
i.e.
create table test as select * from original update test set test.a = .......
I know that they both work individually but whne i try to run them in one file i get "sql command not properly ended" - when i put a comma after 'original' i then get "invalid table name".
Suppose I have a table named table1 which has a field question_Id.There are many values for this field say 100,101,102. Now I want to make a table with the field name 100,101,102 but the problem is that it is not fixed how many values are there for question_id.Here in this example I mentioned three(100,101,102) but it may be anything.How can I make a table with the field names this way?

I'm new to this whole SQL Server 2005 thing as well as database design and I've read up on various ways I can integrate business constraints into my database. I'm not sure which way applies to me, but I could use a helping hand in the right direction.
A quick explanation of the various tables I'm dealing with: WBS - the Work Breakdown Structure, for example: A - Widget 1, AA - Widget 1 Subsystem 1, and etc. Impacts - the Risk or Opportunity impacts for the weights of a part/assembly. (See Assemblies have Impacts below) Allocations - the review of the product in question, say Widget 1, in terms of various weight totals, including all parts. Example - September allocation, Initial Demo allocation, etc. Mostly used for weight history and trending Parts - There are hundreds of Parts which will eventually lead to thousands. Each part has a WBS element. [Seems redundant, but parts are managed in-house, and WBS elements are cross-company and issued by the Government] Parts have Allocations - For weight history and trending (see Allocations). Example, Nut 17 can have a September 1st allocation, a September 5th allocation, etc. Assemblies - Parts are assemblies by themselves and can belong to multiple assemblies. Now, there can be multiple parts on a product, say, an unmanned ground vehicle (UGV), and so those parts can belong to a higher "assembly" [For example, there can be 3 Nut 17's (lower assembly) on Widget 1 Subsystem 2 (higher assembly) and 4 more on Widget 1 Subsystem 5, etc.]. What I'm concerned about is ensuring that the weight roll-ups are accurate for all of the assemblies. Assemblies have Impacts - There is a risk and opportunity impact setup modeled into this design to allow for a risk or opportunity to be marked on a per-assembly level. That's all this table represents.
A part is allocated a weight and then assigned to an assembly. The Assemblies table holds this hierarchical information - the lower assembly and the higher one, both of which are Parts entries in the [Parts have Allocations] table.
Therefore, to ensure proper weight roll ups in the [Parts have Allocations] table on a per part-basis, I would like to check for any inserts, updates, deletes on both the [Parts have Allocations] table as well as the [Assemblies] table and then re-calculate the weight roll up for every assembly. Now, I'm not sure if this is a huge performance hog, but I do need to keep all the information as up-to-date and as accurate as possible. As such, I'm not sure which method is even correct, although it seems an AFTER DML trigger is in order (from what I've gathered thus far). Keep in mind, this trigger needs to go through and check every WBS or Part and then go through and check all of it's associated assemblies and then ensure the weights are correct by re-summing the weights listed.
If you need the design or create script (table layout), please let me know.
Are there any limitations or gotchas to updating the same table whichfired a trigger from within the trigger?Some example code below. Hmmm.... This example seems to be workingfine so it must be something with my specific schema/code.

This Audit Trigger is Generic (i.e. non-"Table Specific") attach it to any tabel and it should work. Be sure and create the 'Audit' table first though.

The trick was getting the Table Name and the Primary Key Columns. I hope this code is found useful.
I'm wondering if there is a control available for creating/modifying db tables through a web interface. I want for users to be able to add/remove, rename, and change the datatype of certain fields in a database table. I've been searching all day online if such a control exists in asp.net but haven't found anything.
I have a table I am trying to create and one of the columns needs to have a decimal that appears as 00.00 and does not round because the data example is 87.09, 86.50, 98.55 etc. I have tried every type of decimal formatting when creating I can find and nothing has worked. When I create the table and upload the data it keeps rounding like this: 87.00, 87.00, 99.00
The only way it does not round is if I do it as a char but that does not seem right when dealing with numerics.

when I select sql server provider pointing to connection mydatabase for Logging the sysdtslog90 table is not getting created. However if I point the connection to msdb - sysdtslog90 it works fine.
Can I have sysdtslog90 under the application database? what are the steps to do this?
I want to be able to create a trigger that updates table 2 when a row is inserted into table 1. However I€™m not sure how to increment the ID in table 2 or to update only the row that has been inserted.
I want to be able to create a trigger so that when a row is inserted into table A by a specific user then the ID will appear in table B. Is it possible to find out the login id of the user inserting a row?
I believe the trigger should look something like this:
create trigger test_trigger on a for insert as insert into b(ID)
I am using the below SQL to insert a table. The problem is after I run this, I run another script to populate the table (see below). The population script will work if I run it as INSERT INTO ... SELECT TOP 99.9999999 PERCENT ..., but if I put 100 PERCENT, or just use no percent limiter I get the following error: Msg 8624, Internal SQL Server error.
It is weird b/c once something is inserted in the table, i can run the populate script without any problems. Any idea as to why this is happening?
Thanks,
Dave

I've done already the schemas for all the tables a you suggested.But when I created a new table the dbo prefix (dbo.ADM.NewTable) appears.I'd like this dbo not to automatically appear whenever i created a new table — as it requires me to alter whenever I created a new table.Is this something that is required to determine the creator of the table?Otherwise, I'd like that to remove.
