SAP policy on use of create,alter, insert and drop in queries

Dear Experts,

I am somewhat new to sap b1 queries.

I understand that it is against the SAP policy to use create,alter, insert and drop in queries. Using them can result in withdrawal of support.

However, I am coming across queries in the forum that do use commands like insert and drop.

So, I am wondering, is it indeed possible to use such kind of queries which are in the public domain without SAP withdrawing support.

Thanks in advance.

Regards
