ORA-01652，temp表空间不足的相关问题
原因分析
1，登录数据库，查看主机日志，报错内容为ORA-01652，temp表空间不足
ORA-01652: unable to extend temp segment by 128 in tablespace TEMP01
2，让业务部门重新执行相关脚本，发现占用temp表空间的具体语句如下，目前temp表空间96GB，大约1个小时会被该sql使用满，sql异常退出
Sql具体如下
INSERT INTO www.WWW_BILL_DTL_TEMP_0101(ACCT_ID,SERV_ID,FEE,BRAND,
PHONE_ID,USER_TYPE) SELECT ACCT_ID, SERV_ID, sum(FEE) FEE,BRAND
,PHONE_ID,USER_TYPE FROM ( SELECT ACCT_ID, SERV_ID, SUM(FEE) F
EE,BRAND,PHONE_ID,USER_TYPE FROM (select a.acct_id,e.serv_id,s
um(b.unpay_fee) FEE,a.brand,a.phone_id,a.user_type from www.ACC_B
