Update stored procedure - SQL Server 2012

Question

I have an error and I cannot find the reason for failing of this procedure. All I know it does something I have no clue about. Does anyone have an idea what is this about? :|

Error:

Conversion failed when converting the nvarchar value 'director' to data type int.

Answer 1

you are checking personid (integer) column against password column which is nvarchar. Update you query to use correct parameter or column and your code should work
