Question

I have a large table that get populated from a view. This is done because the view takes a long time to run and it is easier to have the data readily available in a table. A procedure is run every so often that updates the table.

 TRUNCATE TABLE LargeTable

 INSERT INTO LargeTable
 SELECT * 
 FROM viewLargeView
 WITH (HOLDLOCK)

I would like to lock this table when inserting so if someone tries to select a record they will not receive none after the truncate. The lock I am using seems to lock the view and not the table.

Is there a better way to approach this problem?

Answer 1

BEGIN TRY
 BEGIN TRANSACTION t_Transaction

 TRUNCATE TABLE LargeTable

 INSERT INTO LargeTable
 SELECT * 
 FROM viewLargeView
  WITH (HOLDLOCK)

 COMMIT TRANSACTION t_Transaction
END TRY 
BEGIN CATCH
  ROLLBACK TRANSACTION t_Transaction
END CATCH
