这样的sql，我却做到了。

这样的sql，我却做到了。

题如下

create table A_TEST ( PAYOUT_ITEM_CODE VARCHAR2(30) not null, FORMULA_DET VARCHAR2(1000) ) create table B_TEST ( ELEMENT_ID VARCHAR2(5) not null, NAME VARCHAR2(41) )

求写oracle多个字符替换（有测试数据）

这里需要把a_test表里的formual替换成B_test里的名字。

这个如果用function或者是sp做，就没有什么难度了。 但是用sql做就需要多多考虑一下了

一下是我的sql

select gid, payout_item_code, formula_det, max(substr(txt, 1, length(txt)-1)) from ( select a.gid, a.payout_item_code, a.formula_det, replace(sys_connect_by_path(decode(b.element_id, null, a.signal, replace(signal, b.element_id, b.name)),'##'), '##', '') txt from (select gid, payout_item_code, formula_det, row_number() over(partition by gid order by level) rn, substr(formula_det, decode(rownum-(allcnt-selfcnt), 1, 1, instr(formula_det, '}', 1, rownum-(allcnt-selfcnt)-1)+1), instr(formula_det, '}', 1, rownum-(allcnt-selfcnt))-decode(rownum-(allcnt-selfcnt), 1, 0, instr(formula_det, '}', 1, rownum-(allcnt-selfcnt)-1))) signal from (select a.payout_item_code, a.rowid gid, a.formula_det||'}' formula_det, length(a.formula_det) - length(replace(a.formula_det, '}', '')) + 1 selfcnt, sum(length(a.formula_det) - length(replace(a.formula_det, '}', ''))+1) over(order by rowid) allcnt, sum(length(a.formula_det) - length(replace(a.formula_det, '}', ''))+1) over() sumcnt from a_test a) t1 start with (allcnt-selfcnt)=0 connect by rownum < sumcnt+1 and instr(formula_det, '}', 1, rownum-(allcnt-selfcnt)) >0) a left join b_test b on instr(a.signal||'}', '{'||b.element_id||'}', 1, 1)>0 start with a.rn = 1 connect by prior a.gid = a.gid and prior a.rn + 1 = a.rn) group by gid, payout_item_code, formula_det
