当我想运行我的匿名块时出现此错误
Bind Variable "select" is NOT DECLARED anonymous block completed
这个错误的原因是什么?我该如何阻止它?请帮忙。
您不需要从 dual 中选择 sysdate 以及其他一些问题。
declare filename varchar2(21) := to_char(sysdate, '"MED_LIST_"DD_MM_YY".csv"'); Begin execute immediate 'alter table ext_table location ('''||filename||''')'; end;
