How to split a text attribute by characters in QGIS 2.6.0

Is it possible to make a new column, for example named "Test" and store the first part of the column "Name" split by -?

Answer

Yes you can.

Use the Field calculator with the following expression:

The strpos() function will return the index position of the first '-' character and the left() function "trims" the string before that position.
