SQL查询语句提示”语法错误（操作符丢失）在查询语句Where....中，愁死了，请大师帮忙！

Question

delphi 7 使用ODBC连接DBF数据库，用ADOQuery 查询一直提示如标题的错误，愁死啦，代码如下：
with DM1.ADOTable95 DO
BEGIN
close;
Tablename:='汉字95列标准库.dbf';
Open;
for t:=0 to 77 do
begin
oldf:=Fields[t].fieldname;
s951:=s951+','+oldf;
end;
for t:=78 to 94 do
begin
oldf:=Fields[t].fieldname;
s952:=s952+','+oldf;
end;
s952:='林场,村,林班号,小班号'+s952;

s951:=copy(s951,2,length(s951)-1)+',NFID';

s952:=copy(s952,2,length(s952)-1);

END;//END95Table;
ss1:='Insert into 汉字95列标准库('+s952+') select '+s39+' from '+y+char(32)+'';
ss2:='where ('+y+'.林班 =汉字95列标准库.林班号) and ('+y+'.小班 =汉字95列标准库.小班号)';
with DM1.ADOQuery DO
BEGIN
{ Close;
Sql.Clear;
Sql.Add('insert into 汉字95列标准库('+s951+') select '+s81+' from '+fs+';');

ExecSQL;
}
Close;
Sql.Clear;
Sql.Add(ss1);
Sql.Add(ss2);
Prepared;
ExecSQL;
Showmessage('39列数据输入95库！');

END;//结束SQL

DM1.ADOTable95.Close;
DM1.ADOTable95.Open;
