QTableView and precsions

[baray98]

I use QSqlQueryModel and QTableView in my application to browse data in a database. My database stores some number with decimals points in it. I want my view to just show me just 2 digit after the decimal point. this must be doable is it not? and if so what is the easiest way to do this.

You can either ask the database to trim the numbers using a proper sql function or you can do the trimming after you receive the values using, for instance, QString::number() where you can pass the precision you want.

I am not sure how can i trim using SQL statement ( newbie ) , if you can tell me how please do ..

One thing i could do it inherit QSqlTableModel then trim it right there..is this what you meant by using QString::number()?

That isn't meant cruel, but you should be able to read docs and find such easy informations! Especially if the doc are very well organized like the MySQL one:

MySQL 6.0 Reference Manual :: 11 Functions and Operators :: 11.5 Numeric Functions

There is a nice function called: ROUND(X,D)
