correct：
TARGERT_TABLE ：.table1

This is very unconventional for tsql to allow table alias to be followed after UPDATE keyword. Ref: https://learn.microsoft.com/en-us/sql/t-sql/queries/update-transact-sql?view=sql-server-ver16

PostgreSQL and MySQL all require table name after UPDATE. Need to do more research on dialect supports.
