oracle：动态sql
现在的项目中的用户表是分表的，其实就是一个省一个用户表TF_F_USER_PXX ，其中XX为省份代码。现在引起的问题是给出一个号码，根本不知道在哪个表里，只能知道号码所在的省份后才能查到用户信息。
现在的问题是需要导出某个wvpn成员关系表tf_f_grp_mem中的用户数据，全部导入到tf_f_user表的insert语句 ，其实是为了我移植数据方便。以方便所有数据在同一表中操作。另外由于tf_f_user_pxx表中用户数据的可能存在重复。
根据需求中的描述，我想到的办法是 动态sql查询tf_f_user_pxx中的数据，然后在拼出insert语句。脚本如下：
重点: open c1 for sqlstr
declare
sqlstr varchar2(2000);
sqlstr1 varchar2(2000);
rec sid.tf_f_user_p00%rowtype;
type c_type is ref cursor;
c1 c_type;
begin
sqlstr :='';
sqlstr1 :='';
for recuser in (
select mem_user_id, mem_nbr ,province_code from sid.tf_f_grp_mem where group_id = 10000036 and sysdate < exp_date ) loop
sqlstr := 'select PARTITION_ID, USER_NAME, USER_ID, CUST_ID, USECUST_ID, SERVICE_ID, BRAND_CODE, PRODUCT_ID, PROVINCE_CODE, EPARCHY_CODE, CITY_CODE, USER_PASSWD, USER_TYPE_CODE, SERIAL_NUMBER, SERVICE_TYPE_CODE, PREPAY_TAG, IN_DATE, OPEN_DATE, OPEN_MODE, OPEN_DEPART_ID, USER_STATE, OPEN_STAFF_ID, IN_DEPART_ID, IN_STAFF_ID, REMOVE_TAG, DESTROY_TIME, REMOVE_EPARCHY_CODE, REMOVE_CITY_CODE, REMOVE_DEPART_ID, REMOVE_REASON_CODE, REMARK, IF_ONE_PRO, SID_TRANS_ID, CUST_PROJECT, LICENCE_NO, START_DATE, END_DATE, STOP_FLAG, PROVINCE_USER_ID, FEE_CYCLE, IN_NET_TAG, REV_TAG, USER_GRP_TAG, SML_ENTER_TAG '
