I know at least 3 methods.

1) Simple method:
 Add a parameter query to the "Base document":
SELECT * FROM "Table" WHERE "A" = :param_A AND "Date" BETWEEN :From_Date 
AND :Until_Date

Named parameters are unquoted alphanumeric and start with a colon.
Drag that query into your sheet.
When you access/refresh the parameter query you will be prompted for 
substitution.

2) Add a small filter table to the database, add a criteria input form 
to the spreadsheet and bind it to one particular record of the filter 
table.
The user enters the criteria into the form and refreshes the import 
range which is bound to:
SELECT "D".* FROM "Data" AS "D", "Filter"AS "F" WHERE "Filter"."RowID"=0 
AND "D"."A" = "F"."INT_A" AND "D"."Date" BETWEEN "F"."D1" AND "F"."D2"


3) A generic macro of mine which binds an import range to a changing SQL 
string (not possible in the GUI). For simplicity and better 
customization the macro reads the SQL from a named cell.
