Answer 1, Authority 100%

Mostly all SQL databases support the same syntax from SQL . At the same time, the most basic commands work on one syntax that in MySQL , in MS SQL . Some syntax sugar is possible or vice versa, somewhere you have to specify the name of the table with the schema indicating. Therefore, my advice to you, write on all SQL-typical database with the same syntax and do not worry. If anything, you will understand right away, since there is even a difference, then they are petty.
