Updating column of one table with another table column.

Question

0.00/5 (No votes)

See more:

I have tried out this query for updating a column of one table with the values from a column of a second table.

SQL

UPDATE t1
SET address1 = t2.address1


UPDATE t1
SET address1 = t2.address1
FROM t1 
INNER JOIN t2 ON t1.name_id = t2.name_id
WHERE t1.account_no = '938'


This query is giving an error 
(Error 933: ORA-00933: SQL command not properly ended)

This error is being pointed to "From" or before it, saying that the error is occuring there. Have tried working on the same without the join too but didnt help. Any suggestion on what is wrong will is greatly appreciated.

Thank You.

Please, use this:

SQL

UPDATE t1
SET t1.address1 = t2.address1
FROM TableName1 AS t1 
INNER JOIN TableName2 AS t2 ON t1.name_id = t2.name_id
WHERE t1.account_no = '938'

Do you see changes?

In other words, above means:

SQL

UPDATE
    MainTable
SET
    MainTable.col1 = OtherTable.col1,
    MainTable.col2 = OtherTable.col2
FROM
    MainTable
INNER JOIN
    OtherTable
ON
    MainTable.id = OtherTable.id

SQL

UPDATE PEOPLE a
SET a.SURNAME = (
select b.SURNAME
from PEOPLE b
where b.NI.NO = a.NI_NUMBER
)
