Hi Team,

Could you please list some of the bad practices in SQL, that novice people do?

I have found the use of "WHILE loop" in scenarios which could be resolved using set operations.

Another example is inserting data only if it does not exist. This can be achieved using LEFT OUTER JOIN. Some people go for "IF"

Any other thoughts?

Thanks

Lijo
