SQL关键字附近的语法不正确

Question

I'm trying to insert value 1 to the column isLogged, but it must be on the same row of the player using it.

string checkUserLogStatusQuery = "INSERT INTO [playerInfo] (isLogged) VALUES (1) WHERE PlayerName ='" + checkPlayerName + "'";

I'm getting incorrect syntax near keyword WHERE What would the right syntax be?

Answer 1

INSERT inserts a record, so a WHERE is pointless. You want to use UPDATE :

string checkUserLogStatusQuery = "UPDATE [playerInfo] SET isLogged = 1 WHERE PlayerName = @PlayerName"; // always use parameterized queries
