YOu coud chask on your phpmyadmins ar here piliapp.com/mysql-syntax-check/Nice explanation and i found some error message as Multipart identifier table1.column1 when i executed sample query using your example.
Col1 IN (21, 31) GOMy Query which executed:: UPDATE t1 SET t1.
A1 = 'TRUE' FROM Attendance A INNER JOIN Student S ON A.
This is one of the most interesting questions I keep on getting on this email and I find that not everyone knows about it. Our requirement is that we have Table2 which has two rows where Col1 is 21 and 31. Can you please let me know what are the cases multipart identifier error message will be shown.
In recent times I have seen a developer writing a cursor to update a table. We want to update the value from Table2 to Table1 for the rows where Col1 is 21 and 31. I resolved this by providing the alias name after update query:: UPDATE Table1 SET Col2 = t2.
