请问:
1、在sql数据集中写多重if判断
2、在最后一个判断"select * where name ='fine_username'"中写参数fine_username
下面这样应该怎么改呢?
${if(find("AA",参数)>0,"",if(find("BB",参数)>0,"","select * where name ='fine_username'")}
${if(find("AA",参数)>0,"",if(find("BB",参数)>0,"","select * where name ='"+fine_username+"'"))}
${if(find("AA",参数)>0,"",if(find("BB",参数)>0,"","select * where name ='"+fine_username+"'")}
