I have moved my WPF application to sql server compact edition(3.5) from sql server express 2008.
Case :(With sql server express 2008)
I have used triggers to update column value.
My Column is comma separated string.
When i was inserting value in database table, another table's column value was being updated using trigger.
Eg.
Table 1:Group
Inserting group name=> "My Personal Group"
(Trigger executes) and then
Table 2:Contact
Column:GroupNames = My Personal Group
Now i want to implement same thing using sql server compact edition(3.5) but it does not support triggers.
I don't know about any alternatives as i am new with sql server compact edition(3.5)
Can any one help me?
Thanks in advance
An approach to working around the lack of triggers is in another stackoverflow answer here

I'm new to SQL Server and today I began writing an SQL query. While writing SQL queries in SSMS (SQL Server Management Studio) for insert statements, I noticed that only table names were getting auto completed, but there is no option to auto complete the column name. Is there any way to autocomplete column names in a query?
INSERT INTO table_name (column1,column2,column3,...)
/* Here table name is auto completed. When i type a,a related tables were generated, but for columns there is no autocomplete. */
VALUES (value1,value2,value3,...);
Assuming you are using SQL Server Management Studio (SSMS), which most use people use when working with SQL Server, there is a weaker built in Intellisense that will fill in certain parts of SQL queries for you. If you want something stronger, you can check out third party addins. The most popular are probably SQL Prompt by Red Gate and SQL Complete by dbForge.
I have a two big programs that connect to a SQL Server 2005 database.
Now we will migrate to a new server with SQL Server 2008.. the programs don't work anymore when connected to the new server, the cause is that in all the queries in the programs only table names are used, and they are not dbo tables.. so SQL Server 2008 doesn't recognise them, unless I use the schema name before the table name...
It is very very difficult for me to change all the queries in the two programs to add the schema name before the tables names.
I read in this forum that if I specify the default schema the problem will be solved.. but it haven't been solved though.
The only solution that seems to be working is when I changed the schema of the table to dbo.. but I am not sure if this action will be OK or will it cause some other problems related to this modification?
Is there any better solution?
Will changing the schema of the tables cause me other kind of problems?
Many thanks in advance
Default schemea will work for you. What are the issue with this approach?
Change schema name will cause a big issue and not advisable. Where and how much schema name change?(just think).
You just set a default schema with only one procedure first and check, if this is ok. then change the whole database schema.

In sql server 2005, how do I change the "schema" of a table without losing any data?

I wants to build the tool to reorder the fields of already exist table with data in SQL Sever 2008 R2. Also I want to create a logic to add a column in any specific position. In Mysql or firebird they have the options and TSQL queries to do that.Any body please share whether we have that options in SQL Sever 2008 R2. If any smart logic available means share it to me. Thanks in advance.
Re-ordering the columns of an existing table is going to be a costly process. The table will have to be rebuilt from scratch. SQL does this for you by creating a copy of the table using the new order and then inserting the existing data into that table. Once this is done, the initial table is dropped and the new one put back in place.
A better solution would be to use a VIEW. They can be changed at will.
There is a table in my database containing 100 columns. I want to create a trigger to audit the modification for every update operation.
What I can think is to create the update clause for all columns but they are all similar scripts. So is there any elegant way to do that?
Check Change Data Capture
Update
CDC provides tracking of all details of changes. Available since SQL Server 2008.
(Change data capture is available only on the Enterprise, Developer, and Evaluation editions of SQL Server.
Source: http://msdn.microsoft.com/en-us/library/bb522489.aspx)
More lightweight solution is Change Tracking (Sync Framework), the one code4life mentioned before, available since SQL Server 2005.

There's this resource on MSDN which you might find helpful:
Tracking Changes in the Server Database (including SQL Server 2008)
I'm not sure if you're using SQL Server 2008 though.
Code generation?
Have you looked at the techniques which http://autoaudit.codeplex.com/ uses?
Theoretically, you can use 1 trigger and check COLUMNS_UPDATED() to know which columns has changed.

I have the same question to ask, but I'm using both SQL 2000 Server.
When the table1 in SQL Server 2000 gets updated/inserted/deleted, I have to update another table in SQL Server 2000. How is it possible to achieve that ?
Thanks in advance
Check out: SQL 2000 Triggers.
You should be able to create a SQL Triggers.
I would recommend downloading/install the SQL 2000 SP4. See SP 4 Enhancements - See FIX 884855 .
The accepted answer of the original question does not refer to any version specific features of MSSQL.
Linked servers are also supported in MSSQL 2000.
That's what triggers are for, so yes you can do that. The biggest thing to remember if you haven't written a trigger before is that the trigger fires on the whole batch nor row-by-row, so all code to insert to another table must be set-based not row-based.
To be more specifc as to the code code you need to write the trigger we would need more details as to waht you want to do. Are you creating an audit table? Are you creating a child record? PLease show the details of data going into table1 and what data you would expect the trigger to put into table2 as a result.
