Hello,
currently i tried to understand, what this does:

SQL

convert(varchar(20),((preis)*@prozent),0) as PreisPro

So far as i understand, it uses the field "preis", converts it to varchar(20), multiplies it with the variable "@Prozent" (Percent) and gives it out as "PreisPro".

But what exactly does the Zero number after "@Prozent"?

I'm using MS-SQL.

What I have tried:

I looked into: CAST and CONVERT (Transact-SQL) | Microsoft Docs[^].

There i found the table "float and real styles". Is that number "0" meant?

Not posting as an answer since I'm not 100% positive but it looks like the precision. (e.g. a 0 might return "3" while a 4 might return "3.1416"). Why not just run a select statement and modify it to see the result?

It's a "style" code: SQL Server CONVERT() Function[^] - it's only used for DateTimes, Floats, and Money.
In this case, it probably specifies "No comma delimiters, 2 digits to the right of decimal" as it says in the link.
