SQL - IF EXISTS UPDATE ELSE INSERT Syntax Error

Question

I have the following SQL query:

IF EXISTS(SELECT * FROM component_psar WHERE tbl_id = \'2\' AND row_nr = \'1\') 
   UPDATE component_psar
      SET col_1 = \         


        

Answer 1

Isn't this maybe the most elegant?

REPLACE 
INTO component_psar (tbl_id, row_nr, col_1, col_2, col_3, col_4, col_5, col_6, unit, add_info, fsar_lock) 
VALUES('2', '1', '1', '1', '1', '1', '1', '1', '1', '1', 'N')
