流水账

1、oracle中uuid生成方法：

select SYS_guid()from dual

2、instr()函数 ???

    SELECT recordid, optselfqty, optcode, invoicecode, awardflag
              FROM tb_inv_asstypeacc
             WHERE orgdeptcode = v_orgdeptcode
               AND  instr(v_invoiceCodeStr,invoicecode)>0) ；表示invoicecode在字符串invoiceCodeStr内，即invoicecode  IN  v_invoiceCodeStr

3、trunc()  把时间格式2007-09-26 17:14:56转换成2007-09-26

      eg:   select t.insertdate,trunc(t.insertdate) from tb_reg_entagentsaleresult t
