I want to migrate specific data of one table to another specific column which is in another database in MySql

Question

I just use the following query but it shows error. Any suggestions?

INSERT INTO test1.`tbl_news`.`file` 
SELECT * FROM test2.`tbl_download_media`.`media` 
WHERE TYPE = 'event'

Here I want to copy data from table tbl_download_media which have column media and type event of DB test2 to DB 'test1' having table tbl_news with column file

Here is the error:

Error Code: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '.file select * from nic_data.tbl_download_media.media where type = 'event' at line 1

Answer 1

Your insert statement has some minor syntaxis errors. This is the corrected version:

INSERT INTO test1.tbl_news(`file`) 
SELECT media FROM test2.tbl_download_media
WHERE TYPE = 'event'

Now, if you want to update based on same id for event type:

UPDATE test1.tbl_news AS b
INNER JOIN test2.tbl_download_media AS g 
ON (b.id = g.id)
SET b.file = g.media 
WHERE TYPE = 'event'
