Hello,
You can create your query through the commandline tool 'psql', and once
you have that working you can test through the 'ogrinfo' commandline
tool, using its '-sql' switch. Then you can test through MapServer with
the 'shp2img' commandline tool, by setting that query within the DATA
statement of your mapfile layer. See examples at

I have a PostGIS database and I have a column "startdate" and "enddate" in my
database (YYYY-MM-DD format).
What I want to do is make a filter/expression that checks if a certain
selected date falls between those 2 dates.
Example:
I have a checkbox for enable/disable the following layers:
2016
2017
2018
2019
2020
I have an entry in my database with:
startdate: 2016-01-01
enddate: 2019-01-01
If I check the layer 2017, I would like it to check if its between the
start/enddate and if yes, display it.
Is this possible with Mapserver/Openlayers?
