if (nid = -1)
sql.append(" and nid=" + nid);

sql.append(" and sname like '%" + skey + "%'");

这段代码哪里有错误呢
if (pastart = -1) sql.append("select * from("); sql.append("select nid,sname,sdescription,nprice,sif (pastart = -1)sql.append("select * from(");sql.append("select nid,sname,sdescription,nprice,simg,(CASE smctag WHEN '0' THEN '有货'WHEN '1' THEN '
你最后把 sql语句输出来 放进去查询看看 就知道那里错了
