Hello,
I am using simple update query.

SQL

update tmOredr set RequiredVectorFormatTypeID = null
where  IsEmbroideryOrder =0 and RequiredVectorFormatTypeID=7

But it is giving me this error.

XML

Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
The statement has been terminated.

I dont understand where is subquery? Please help.

Thanks

Reason for update
Sorry i was trying self join so i post it wrongly. Actually I have used where clause

I don't think this is valid syntax:

SQL

UPDATE
    tmOredr
SET
    RequiredVectorFormatTypeID = null
WHERE
    IsEmbroideryOrder = 0
    AND RequiredVectorFormatTypeID = 7

Should you not be using the where operator?

SQL

update tmOredr set RequiredVectorFormatTypeID = null
WHERE  IsEmbroideryOrder =0 and RequiredVectorFormatTypeID=7

Sorry for wrong typing. Actually I have used where clause. I have updated question. Please Check it.

There is a race condition as you are trying to set values to the same column you are doing a where clause on.

Try something like this
(though Im not sure if it will work).

update a set a.RequiredVectorFormatTypeID = null
FROM tmOredr a
INNER JOIN tmOredr b ON a.RequiredVectorFormatTypeID = b.RequiredVectorFormatTypeID
WHERE b.IsEmbroideryOrder =0 and b.RequiredVectorFormatTypeID=7
