ORA-06553：PLS-306：调用“ SUBSTR”时参数的数量或类型错误

Question

我正在oracle中运行以下查询，并且遇到错误 ORA-06553 。

select cast(cbdev.cbchr(utl_raw.substr(4500, 5, 26)) AS DECIMAL (14, 2)) as grant_held 
  from bs_transaction 
 where account_coid = 'TS 0014 T8324J3L2V' 
   and txn_id = 21;

不确定语法正确时为什么substr会引发错误。 有人可以帮我吗

Answer 1

尝试以下操作：

select cast(cbdev.cbchr(utl_raw.substr('4500', 5, 26)) AS DECIMAL (14, 2)) as grant_held 
  from bs_transaction 
 where account_coid = 'TS 0014 T8324J3L2V' 
   and txn_id = 21;
