Question

I’m trying to delete a series of rows in a MySQL table from a list of ID’s in C#. There’s an employeeID row in the table. Basically my question is what kind of syntax would I use?

Answer 1

You would probably use an IN clause in your DELETE:

DELETE FROM `EmployeeTable` WHERE EmployeeID IN (2, 3, 4, 5, ...)

This could be implemented with the String.Join method to generate the list:

var query = "DELETE FROM `EmployeeTable` WHERE EmployeeID IN (" +
    String.Join(",", myArray) + ")";
