Question

我正在尝试使用绑定变量在Oracle中运行此查询。需要知道为什么会出现以下错误。我确实认为我的语法有问题，不能弄清楚它是什么？

variable start number;
variable end number;
exec :start := 1;
exec :end := 2;

我的错误说明了这一点：

Error report:
SQL Error: ORA-01745: invalid host/bind variable name
01745. 00000 -  "invalid host/bind variable name"

对此有所帮助。我是绑定变量的新手提前致谢

Answer 1

START和END是保留字。

SQL> variable start number;
SQL> exec :start := 1;

PL/SQL procedure successfully completed.

SQL> select :start from dual;
select :start from dual
        *
ERROR at line 1:
ORA-01745: invalid host/bind variable name

使用其他名称，并记住使用:引用SQL中的绑定变量：

SQL> variable asdf number;
SQL> exec :asdf := 1;

PL/SQL procedure successfully completed.

SQL> select :asdf from dual;

     :ASDF
----------
         1

将来，您可能希望最小化代码示例。问题相对简单，但是巨大的代码块隐藏了它。
