I don't have access to SQL-Server 2005 from this machine, but you should be able to create tables like:

create table MyTable(
  Id int identity(1,1) not null,
  MyBigColumn varchar(max) null
  )

I believe that Microsoft are recommending use of "varchar(max)" instead of the "text" data-type.

It depends what you mean by "arraging the records with the latest date"

SELECT * FROM MyTable ORDER BY SomeDateColumn

I have never come across a situation where that was useful.

Use GOTO - or better would be to create a proper conditional structure with an IF block.

I have a the following table structure

t_entity
entity_id
connect_date
disconnect_date

t_entity_info
entity_id
property_name
value

Let's say I have the following data in the tables
t_entity
1 | 1/1/2005 | 12/1/2005
2 | 1/1/2006 | 12/1/2006

t_entity_info
1 | application | ds3
1 | subapplicaiton | wan
2 | application | voice
2 | subapplicaiton | phone

I want the following results with one query (using Oracle)

1 | 1/1/2005 | 12/1/2005 | ds3 | wan
2 | 1/1/2006 | 12/1/2006 | voice | phone

Anyone got any ideas? Thanks in advance.

Calculated starting from zero. OOps. That only works if you are worried about a context out of range error! Big Grin | :-D

Any suggestions for this guy. I prefer 2005 because of SMO and SQL Server Express is free. Plus, nifty serialization and inside out CLR.

1. See "http://www.microsoft.com/sql/prodinfo/overview/whats-new-in-sqlserver2005.mspx[^]".
2. I would go for SQL Server 2005 because it will be supported longer. I would mainly only consider SQL Server 2000 if you already had licences.
3. Both should work the same from .NET 2003. NET 2005 would definately favour SQL Server 2005.

Regarding Triggers

Syed Muhammad Kamran23-Jan-07 3:48

23-Jan-07 3:48

I am developing an sms messaging app (Let say app A) with backend in SQL2K. This app depends on a schema of an already deployed application (Let say app X). I have also created a schema of my own application which may reside on any other machine.

Whenever app X done a transaction on some of the tables I am initiating a trigger from there. After doing some operations on the inserted record in the trigger I am inserting that record to my own schema generated for App A by the link server to my Schema.

I have made a windows service, whenever a new rocord is inserted in my tables through schema I'll compose and send an SMS message to my client.

My problem is since triggers runs in an implicit transaction whenever the inserting triggers fails the transaction which was inserted by App X is also got failed. Which I don't want. How to cope with this... I don't know about error handling. How to implement fail save recovery in this scenario.

Loops in ERD

Hi All,

I want to know whether loops in ERDs are wrong or show weak design or not.
Example: if table A is connected to table B & table B is connected to C & C is connected to A..
Is this wrong??
Actually the ERD is larger than that & the alternative is to make multiple joins when retreiving data so I want to know which is better.
Thanks a lot

The tightest "loop" (relationship) you can have is when a table joins onto itself - which is perfectly valid.

e.g. An employee has a manager, a manager is an employee also. So the managerID column of the employee table refers to the ID of another employee.

Not sure exactly what you are trying to do, but if you need to look for a particular value and if you are using datatables you could loop through your column names and in each loop run a datatable.select command, storing the values in an array.

More information would be helpful.

The syntax for SQL Server 2000 is:
1. EXEC sp_rename 'old_table_name', 'new_table_name'
2. EXEC sp_rename 'table_name.old_column_name', 'new_column_name', 'COLUMN'
3. ALTER TABLE table_name ALTER COLUMN column_name new_data_type
4. Lookup "ALTER TABLE" in "SQL Server Books Online".
