如果$fine_username为AAA或BBB,查所有的信息,如果不为这几个指定的用户,则要
加 WHERE USER_NO=$fine_username, 这个如何写SQL
where 1=1
${if(or(fine_username="AAA",fine_username="BBB"),""," and USER_NO='"+fine_username+"'")}
${if(or(fine_username="AAA",fine_username="BBB"),"","and USER_NO='"+fine_username+"'")}
${if(find(fine_username,"AAA,BBB")>0,""," and USER_NO ='"+fine_username+"'")}
