I'm trying to make a style based on rules, and I want to use a boolean field I have created for that.

But I do the following:

"field" like 'TRUE'
"field" like TRUE
"field" like 1
"field" like '1'

and nothing is selected.

How can I select true values in a boolean field then? I'm using QGIS reading from PostGIS database.

    Would you be able to edit your question to include the GIS software that you are using, please ? – PolyGeo May 25 '15 at 20:11

    I don't think the boolean field supports the like operator, try "field" = 1 instead. – Michael Stimson May 25 '15 at 21:18
  • What data source are you using? QGIS doesn't even support creating bool fields in new Shapefiles or Spatialite afaik. – underdark May 25 '15 at 21:54
  • Sorry: I'm using a postGIS database – user3733164 May 25 '15 at 22:06

Finnally I have found the solution:

"field" like 't'

Thank you

I would recommend, in order to see how QGIS views the values, to use the "all unique" button.

You should get a list of values.
