Subject:      Proc Sql Update with 2 Tables


I am trying to update a variable (mq511m4) in one table (H10q_r2) with the values of a variable(mx055) in another table (Grids_new02142) using the following code.

proc sql; update work.H10q_r2 q set mq511m4 = (select g.mx055 from work.Grids_new02142 g where g.sampid = q.sampid and g.mx054 = q.mq511m4) where sampid in (select sampid from work.Grids_new02142);


Unfortunately, after the processing is finished the variable I am trying to update contains only blank data.

Any suggestions on how to fix the code would be appreciated.
