Vijesh — Tue, 11 Apr 2023 05:51:12 GMT

I have two tables EMPLOYEE & EMPLOYEE_ROLE. I'm trying to Update a column with a value from another column. I'm using SQL server join but i get an error -

[parse_syntax_error] Syntax error at or near 'FROM' line 3.

UPDATE C

SET C.title = B.title

FROM EMPLOYEE C

INNER JOIN EMPLOYEE_ROLE B

ON C.emp_id = B.emp_id

AND C.emp_name = B.emp_name

From the documentation, update statement is only supported for Delta Lake tables.

https://docs.databricks.com/sql/language-manual/delta-update.html. Can you check if your tables are delta

@Vijesh V , you can use merge statement like below code snipplet:

merge into EMPLOYEE C

using EMPLOYEE_ROLE B

ON C.emp_id = B.emp_id AND C.emp_name = B.emp_name

when matched then

update set C.title = B.title

Hi @Vijesh V

Try to use merge into to perform cdc between tables :

MERGE INTO target a

USING source b

ON {merge_condition}

WHEN MATCHED THEN {matched_action}

WHEN NOT MATCHED THEN {not_matched_action}
