[firebird-support] How to get a list of columns from another select

[jorg...@yahoo.com [firebird-support]]

Hello everyone:
 

 Is there a way I can select out the column names from any query? 
 Ideally something like:
 

 Select column_names From (Subquery)
 

 I do not want the query results, I want the names of the columns.
 

 Example

 Select column_names From (Select NumberInst As #Inst, DescInst As Description, 
Type From Instrument Where NumberInst = 10)
 I want get:
 #Inst
 Description
 Type
 

 Thank you so much.
