FR4 + Delphi + ADO + PostgreSQL timestamps

Hello everyone,

I'm just starting with FR4 and i find it very powerful. I'm facing some issues though.
We have a Delphi (2006) application with FR4.
I load a report and pass date variables.

In my PosgreSQL DB my date fields are 'TimeStamp without timezone' typed.
I tried passing my variables as TDateTime, TimeStamp, String.
Nothing seems to work. I can see correctly the variable values but when i want to filter with them in an TADOQuery SQL (ex ' myTable.myDateField > my variable ') it doesn't work.

Does anyone already have to deal with timestamp field in postgres?

Thanks

    Have you tried to use casting the date or column value?

    In my query? I tried but maybe my syntax is wrong. How would you write it?

    In Firebird it would be (I have no experience with PostGreSQL)

    CAST( <column> AS <DATATYPE> ) AS <castedColumn>

    e.g.

    CAST( DATE_TIME_STAMP_COLUMN AS DATE ) AS DATE_ONLY
