I have the following data in a table TABLE1

DOCUMENT —— FIELD1

23456
34567
45678
98765

i have the following data in a view VIEW1

DOCUMENT —- BUS
12345 ———— 5
23456 ———— 6
34567 ———— 8
45678 ———— 12
98765 ———— 14

What i would like to do is update each row

if (table1.document = view1.document)
then
table1.field1 = view1.bus

Any insight will help.

Thank you.

Answer 1

That can be done using plain SQL, no procedures required:

UPDATE table1 SET field1 = (SELECT bus FROM view1 WHERE table1.document = view1.document)

Or, if your database allows it:

UPDATE (select table1.field1, view1.bus FROM table1 JOIN view1 ON table1.document = view1.document) SET table1.field1 = view1.bus
