Answer 1

Gaurav,

Would like to understand few things.

Whether you want to delete the records in a table based on the count of rows (parameter)? irrespective of which 10 or 40 records to be deleted.

Below link has the sample stored procedure to delete the records (result of search query) from the table.

Hope it will solve your issue.

Answer 2

Another approach you can take is schedule the deletion of rows during a time when database is not used.

Example during Night.

Then you would not need to implement any extra logic.

But use this, only if deletion can be done later.

Answer 3

CREATE PROCEDURE spDeleteRecord
@DeleteBatchSize INT,
@DelayTime DATETIME
AS
BEGIN
SET NOCOUNT ON;
DECLARE @DeleteRowCount INT
SET @DeleteRowCount = 1

WHILE (@DeleteRowCount > 0)
BEGIN
BEGIN TRANSACTION
DELETE TOP(@DeleteBatchSize) SchemaTableName;
SET @DeleteRowCount = @@ROWCOUNT;
PRINT @DeleteRowCount;
COMMIT
WAITFOR DELAY @DelayTime
END
END
GO
