Question

I thought this SQL select statement works, right?

Asked by: chuang4630

declare @status int

select field_1, @status = field_status
from mytable
where field_status = 2 and field_3 = 4

I thought this SQL select statement works, right?

Instead, I receive an error about "@status = field_status".

Any opinion?

With your SQL statement, you will get the following error:

Server: Msg 141, Level 15, State 1, Line 2
A SELECT statement that assigns a value to a variable
must not be combined with data-retrieval operations.

Try removing the field_1 from your statement

declare @status int

select @status = field_status
from mytable
where field_status = 2 and field_3 = 4

So I have to do assignement for every field, right?

 

by: aneeshattingalPosted on 2006-05-22 at 11:01:51ID: 16736438

You can use like this

SELECT @Filed1 = Col1,
            @Fileld2 = Col2
FROM urTable
Where Some Condition

 

by: rafranciscoPosted on 2006-05-22 at 11:02:38ID: 16736445

Yes, you have to do assignment for every field, or if you don't need it, remove it from the SELECT statement.  You may also refer to the following links:

In ur case it is

declare @status int
declare @Field1 varchar(100)  --- change the datatype

select @Field1 = field_1,
         @status = field_status
from mytable
where field_status = 2 and field_3 = 4
