- Applications must use query parameters to pass values that correspond to encrypted columns. For example, when inserting data to encrypted columns or filtering by encrypted columns (when using deterministic encryption). Passing literals or T-SQL variables corresponding to encrypted columns isn't supported. For more information specific to a client driver you're using, see [Develop applications using Always Encrypted](/sql/relational-databases/security/encryption/always-encrypted-client-development).
