比较简单直接的sql语句

Recordset1.Source = "SELECT * FROM 表 WHERE 字段 LIKE '%" + Replace(Recordset1__MMColParam, "'", "''") + "%' or 字段2 like '%" + Replace(Recordset1__MMColParam, "'", "''") + "%' ORDER BY id DESC"Recordset1.Source = "SELECT * FROM 表 WHERE 字段 LIKE '%" + Replace(Recordset1__MMColParam, "'", "''") + "%' and 字段2 = 2 ORDER BY id DESC"

下面是一些补充

函数名：keyword_sousuo
作 用：生成sql查询条件
参 数：table_field ------ 表的字段名（之间用逗号分开）
keyword ------ 搜索关键词（之间用空格分开）
返 回：sql查询条件
