    Haven’t messed with TEXT data type in forever. But, leaving aside the questions about the wisdom of text “key” columns, you’ll need to use like. You cannot use standard comparison operators on TEXT and NTEXT (=,<=, etc).
    You can leave out the wildcards, so it’ll behave like an exact match. So if your keyy column is text:

    update win set seq=? where keyy like ?

    BTW, TEXT and NTEXT have been deprecated for several versions of SQL Server, I’m sure that one of these days they’re going to drop it. You should probably look into converting to CHAR and VARCHAR.
