Save ROWCOUNT value in a variable

Hello. I want to save the RowCount returned value in a variable and want to print (+1 with 'A' prefix).

I created a variable as int.

declare @TotalIntRow as int

Now I'm unable to assign the returned value of rowcount in a variable.

i use these ..

@TotalIntRow = select Count(*) from Rcount

Error :- Msg 137, Level 15, State 2, Line 1
Must declare the scalar variable "@TotalIntRow".

set @TotalIntRow = select Count(*) from Rcount 

Error : - Msg 156, Level 15, State 1, Line 1
Incorrect syntax near the keyword 'select'.

[I also tried to add a demo value , Set @TotalIntRow = 1; , but showing message number 137 as above mentioned]

How could I save the value in it.

Try this one;

DECLARE @TotalIntRow AS INT
    SET @TotalIntRow = (SELECT COUNT(*) 
                          FROM Rcount)
PRINT @TotalIntRow

Don't forget that the DECLARE statement should be used to declare the variable, before using it.

Hope this helps Smile | :)

Awesome mate.

But I cant understand one thing, if I do these steps individually I got scalar error something. why so ? just curious about it. Ain't the values are stored permanently in it?

BTW.. If even I run the above scripts do the variable takes additional space or they get removed after application shutdown?

Begin
DECLARE @TotalIntRow AS INT
    SET @TotalIntRow = (SELECT COUNT(*) 
                          FROM Rcount)
print @TotalIntRow + 1
Insert into Rcount Values(@TotalIntRow)
End

I m getting my partial desired result. I want to add prefix 'A' with the result set .. When I did .. I got , can't convert (variable declared for storing A) to int data type..

Oh my god, I can't believe I did it..

Begin
DECLARE @TotalIntRow AS INT
    SET @TotalIntRow = (SELECT COUNT(*) 
                          FROM Rcount)
print @TotalIntRow + 1
Insert into Rcount Values('A'+ Convert(varchar, @TotalIntRow))
End

Not permanent, they are 'lost' once the command is finished executing. (In this case, once it passes the END statement) That's also the reason why they can't be executed separate, they are interpreted as separate commands if you execute them line by line separately.

They are gone as soon as the script (the complete collection of lines) are finished, unless you store them in a table somewhere. Most applications execute their script and close the connection to the database when done.

Good work Smile | :)

Missing data recovery

I am using a piece of automation software called Taskcentre, this has it's own database. This morning we were having issues with the software and it turns out that an essntial table has been cleared of all data.

There are currently no backups for the database and all tasks that have been created over the past year are now gone unless i can find a way of restoring the database to 2 - 7 days ago.

I was wondering if anyone had any ideas.

Hi Bob

How do you mean Audit table?

Re: Missing data recovery

Ashfield21-Apr-09 8:31

Is there any automatic auditing going on to record actions on the table - you know, who added/changed/deleted a record. If so, you may be able to recover your data that way. If there is nothing obvious you could contact the vendor and ask them if they have any suggestions. Otherwise, I'm afraid you have learnt the hard way that you should always do backups.

To add to Bob's reply. Not only should you always do backups you should also make sure you can restore them.
Once worked in a place that did backups every day. When a hard disk crashed they discovered that the backups would not restore. Three months accounts data lost and had to be manually re-entered from documents. Smile | :)

Thank you for all of your replies, it seems that I have lost all of the data and as you said I have learnt the hard way that we should keep on top of ALL our backups. Thankfully it shouldn't take too long to recreate the tasks, just means by busy couple of months just got a whole lot busier.

Thanks again

So split the recipeints by comma and repeat the insert for each one.

I just did, split the recipients using text.split
Insert each record using your current insert method, changing the recipeint each time.

What are you doing over here - go back to the ASP forum where they may have more patience with fools - you obviously have no idea what you are doing.
