Delete a batch of records with one statement

First, the ID column is int to identify the class type, and then delete the columns whose ID value is 5, 6, 8, 9, 10, and 11. Here, the cast function cannot be replaced by the convert function, and the conversion type must be varchar, it cannot be char, otherwise it will execute the result you don't want. Here, "5, 6, 8, 9, 10, 11" can be the value built by a chkboxlist you get on the page, delete all the following statements.
Besides, it is more efficient than using multiple statements in a loop.
Delete from [Fuji] Where charindex (',' + Cast ([ID] As varchar) + ',' + '5, 6, 8, 9, 10, 11, '+', ')> 0
Another type is
Delete from Table1 where ID in (1, 2, 3, 4)
