Access the Field Origin ?

[luapfr]

Is it possible to access the SQL Origin that make up a field?
SQL Example ::

MAX(VE.DATA_EMISSAO) As DATA_COMPRA,

In this example, the Field Source would be
"MAX(VE.DATA_EMISSAO)"

I have to do this with IBDac
where I pass the Field Name "DATA_COMPRA"
and he would return to me "MAX (VE.DATA_EMISSAO)"

Thankful.

Unfortunately, this functionality is not supported in IBDAC, since Firebird does not allow obtaining the required information.
