Question

I get multipart can not be bound error on following query

update nfltx
set 
b.boxno = a.boxno,
b.message = a.message,
b.nameboxno = a.nameboxno,
b.namemsg = a.namemsg,
b.phoneboxno = a.phoneboxno,
b.phonemsg = a.phonemsg

FROM ofltx a JOIN nfltx b 
ON a.ls_fullnam = b.ls_fullnam

but if i remove b from boxno message and all i do not get the error . What is the reason behind this. Thank You using sql server 2008

Answer 1

A table alias specified in a FROM clause cannot be used as a qualifier in SET column_name. This is not valid:

update nfltx
set 
b.boxno = a.boxno,
b.message = a.message,
b.nameboxno = a.nameboxno,
b.namemsg = a.namemsg,
b.phoneboxno = a.phoneboxno,
b.phonemsg = a.phonemsg

FROM ofltx a JOIN nfltx b 
ON a.ls_fullnam = b.ls_fullnam

To make it work, remove the b. alias from the column name.

update nfltx
set 
boxno = a.boxno,
message = a.message,
nameboxno = a.nameboxno,
namemsg = a.namemsg,
phoneboxno = a.phoneboxno,
phonemsg = a.phonemsg

FROM ofltx a JOIN nfltx b 
ON a.ls_fullnam = b.ls_fullnam
