I have adapted the solutions already posted on this question to my task but it is still generating the error:
Unknown column
testbr.Tel
in 'field list'
UPDATE `Test_file_base_record_subset` `testbr`
INNER JOIN `UKTI_16sep15` `ukti`
ON `ukti.UKTI_Short_UID`=`testbr.ShortUID`
SET `testbr.Tel` = `ukti.UKTI_Tel`
WHERE `testbr.Year`=2015
Please tell me where I am going wrong. Thanks.
