This statement:-
var
ws_bdr_date : TDateTime

begin
ws_bdr_date := StrToDate(Edit1.Text);
with IBQuery1 do
begin
Close;
Sql.Clear;
Sql.Add ('Select adj.ADJ_NO, adj.SRC_PLU, adj.DEST_PLU, ' +

'where adj.ADJ_DATE = ws_bdr_date ' +
' and adj.ADJ_SOURCE = ''Stock Adj'' ' +
'order by adj.ADJ_NO');
Open;
end;

using this statement returns "Dynamic SQL error
SQL error code -206
Column unknown WS_BDR_DATE ..."

What should I do?
