Re: Update query

["Jim Essinger" <dilbernator@xxxxxxxxx>]

Marco,
I have found that you need to state the connection between the 2 files
twice.  Once to select the field that has the new value, and a 2nd time
to eliminate any null values from mis-matches.

Try this

UPDATE EI_Gcfmd A SET A.DESEMD =

(SELECT B.DESEMD

 FROM EI_GcfmdMS B

 WHERE B.GFMEMD = A.GFMEMD AND
       B.EMBEMD = A.EMBEMD AND
       B.MODEMD = A.MODEMD AND
       B.CIAEMD = A.CIAEMD AND
       B.SOCemd = A.SOCemd)

WHERE EXISTS

 (SELECT 1

 FROM EI_GcfmdMS B

 WHERE B.GFMEMD = A.GFMEMD AND
       B.EMBEMD = A.EMBEMD AND
       B.MODEMD = A.MODEMD AND
       B.CIAEMD = A.CIAEMD AND
       B.SOCemd = A.SOCemd)
