What does '' inside the "" mean in Sql

[aliiiish]

strSQL = "SELECT setting_value FROM _setting WHERE Setting_Name = 'Interface_Installed'

Same as " in language you are using above - string quote delimiter.

It is telling you that 'Interface_Installed' is a string which you are trying to match, not another field name in the table.
