I'm facing a scenario, where if the input is 10, I want a sequence of numbers (1,2,3,...10).
In oracle the level function provides that function, and I wish to know how to perform the same task in MySQL.
Thanks...

You can Use this query in mysql
SET #rownr=0;
SELECT #rownr:=#rownr+1 AS `rowNumber` FROM `tablename` limit 10
the above query generate sequence of that number upto the limit.
Tablename is any of your table in db

What do the following three settings mean in MySQL Workbench?
These three parameters are mentioned briefly on the General Editor Settings, but I'm wondering what might be an example of their usage. For example:

Does this mean, for example that:
SELECT * from main_iteminstance
is different from:
SELECT * FROM main_iteminstance
The answer is no when I tried both, but isn't FROM a sql identifier, so what would this setting mean exactly?
