<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal">I am trying to use a filter expression to only display features where a value is true in a Boolean field coming from an MSSQL Spatial datasource. It seems like every syntax I try MapServer comes back with “An expression of non-boolean
type specified in a context where a condition is expected”<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have tried a number of different combinations. How do you specify a Boolean expression? Has anyone got a Boolean field type to work from a database source? If so what expression did you use?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks!<o:p></o:p></p>
