Answer 1

You've got an illegal identifier in an SQL query ("E-mail"). Andrew's suggestion to quote it is the proper solution if that's the actual column name. You may have mis-spelled it in the query though.

Answer 2

You need to quote the "E-mail" column name so that the SQL parser will accept it. An unquoted/escaped dash is the subtraction operator in SQL, so "E-mail" unquoted means you're asking the SQL server for the result of subtracting columns named "E" and "mail".

The proper SQL would be:

SELECT Id, MobileNumber, Country, First_Name, `E-mail`, Address, Identity, Zip, Last_name, City, State, Position FROM employee_table WHERE (Id = ?)
