I am trying different queries in the Query Builder. Is there a way to comment the query? I tried with

/* */

#

--

without success :

An error occurred when executing the query. The data provider said: OGR[3] error 1: SQL Expression Parsing Error: syntax error

EDIT : Thanks to the answer and comments of @Joseph,
I have made a feature request of this question: http://hub.qgis.org/issues/10914

Welcome to GIS! Unless I'm mistaken, I don't think you can comment queries in the Query Builder. –  Joseph Jul 17 at 12:18
    
Is there an other way to build queries then (and comment them as required ?) (Thx for editing, it looks much better) –  nebi Jul 17 at 12:48

You can build queries by using the Query Builder or an alternative is to use the Expression string builder (Layer Properties > Style > select Rule-based > add a rule > insert your command in the Filter box or click the '...' button to bring up the string builder interface.

In both cases, I do not think QGIS supports the comments function when creating expressions for filters/queries:

True, with this way you can save your rules and import / export them ... But it's not as quick as commenting with some symbol at the beginning of the line. Copy / paste in the query Builder is tedious –  nebi Jul 17 at 13:58

@nebi, you could always send a request for this to be implemented in future updates. –  Joseph Jul 17 at 14:11
    
Yes, I want to do it –  nebi Jul 17 at 14:12
