Hi, I have 2 tables which have one common field, I need to ensure that few rows are updated as in table 1 in table 2:
for eg:

Table 1
Common_Field Name
1234 Chandan
4321 Kiran

Table 2
Common_Field Name
1234 Raj
4321 Kiran

Intended Result:
Common_Field Name
1234 Chandan
4321 Kiran

Please let me know, Thanks

So the Name in table2 should be updated to the Name of table1 if Common_field is matching and Names are different?
Try:
update t2
set Name = t1.Name
from table2 as t2
join table1 as t1 on t1.Common_Field = t2.Common_Field
where t2.Name <> t1.Name
