There are tables inserted and deleted to indicate in which rows there are changed values.

Of course, if you are trying to set value = 3 where it was 3 before...

Actually yes.

There are 2 issues in your approach:

1. You are doing full updates even if nothing changed in the table;

2. Data in your "updated" column is inconsistant with the rest...

It's much easier to have IDENTITY column.

Sorry, it does not make any sence.

What does it mean - multiple statuses can be entered into the table simultaneously?

What's a point to apply status if it's already overwritten...

It's better to have DateChanged column with default GETDATE().

Column            Data Type 

Status_Code    Int                 Not null     

Request_Id      Int                 Not Null       Key

DateChanged   smalldatetime   Not Null       Key

It gives you more information and stores some kind of...

you cannot use variables within IF UPDATE. You must explicitly specify column name:

   IF Update(Consumer_info)

If you wand to dynamically define which column to check for updates use COLUMNS_UPDATED().

Are you going to update whole table 4 times every time any single row is updated?

Hard drives on your server not gonna stay long.

Why you need to store your code as SP if you can execute it immediately when you need it?

Are you trying to allow users to create SP from front end...

Check data in your table first.

Use

SELECT ...

WHERE ISDATE (WCvideoAmount) = 0

It will show you all rows with values causing error.

If there is no BEGIN ... END only the first followin statement is included into IF.

After this 1st statement IF is considered finished and 2nd statement will be executed without...

SELECT ...

FROM TABLE

WHERE

tarih >= convert(datetime, convert(int, GETDATE() - 0.5)) + convert(datetime, '1900-01-01 16:00:00')

and

tarihb <= convert(datetime,...

Can you explain in plain English what are you trying to achive?

As I understand, you have table with log of calls or something and another table with tariff definitions, e.g....

Why?

Everything is before your eyes.

Just don't be lazy.

SELECT ...

FROM TABLE

WHERE DateTimeColumn between convert(datetime, convert(int, GETDATE() - 0.5)) + convert(datetime, '1900-01-01 16:00:00') and convert(datetime, convert(int, GETDATE() - 0.5)) + convert(datetime, '1900-01-01...

Add year to PRIMARY KEY.

If Cost1 is null, @ReturnValue becomes null in first statement, and all conditions will not be be true, so no further statements to execute. @ReturnValue will stay NULL till the...
