Hi,
what do you mean by NUMBER here.
Is that a column present in both the tables? |

then you can try the following query
UPDATE X
SET <COLUMN NEEDS TO BE CHANGED> = <DESIRED VALUE>
WHERE NUMBER IN (SELECT NUMBER FROM Y)
Above query will update for all the matching NUMBER col values. If you want it to be done for specific then you may need to add WHERE clause to the inner query. |
