Having difficulty writing a statement that will allow me to:
UPDATE column C in DB1.table1 with data from column B in DB2.table2 IF column B IS NOT null AND column A FROM DB1.table1 = column A FROM DB2.table2 (matching IDs)
Can’t tell if I need to use a CASE statement or IF. Appreciate any help, thanks.

UPDATE DB1.table1 JOIN DB2.table2 ON DB2.table2.B IS NOT NULL -- IF column B IS NOT null AND DB1.table1.A = DB2.table2.A -- AND column A FROM DB1.table1 -- = column A FROM DB2.table2 (matching IDs) SET DB1.table1.C = DB2.table2.B -- UPDATE column C in DB1.table1 -- with data from column B in DB2.table2
