Oracle连接字符串报错误ORA-01722:无效数字的解决方法,如下函数,用来查出名字相似于某字符串

Oracle连接字符串报错误ORA-01722:无效数字的解决方法,如下函数,用来查出名字相似于某字符串create or replace function f_GetUsers(key in varchar2,

p_cursor out pkg_test.myrctype)

return number is

Result number;

begin

open p_cursor for

SELECT * FROM Accounts_Users where TrueName like '%'+key+'%' order by UserID;

Result := 0;

return(Result);

end;

编译成功,,测试的时候也没有发现错误,但是到了真正的生产环境的时候,

报错误 ORA-01722: 无效数字 很莫名

后来查阅网络

发现ORACLE 的字符串连接必须用||符号的,然后修改测试 如下

create or replace function f_GetUsers(varkey in varchar2,

p_cursor out pkg_test.myrctype)

return number is

Result number;

begin

open p_cursor for

SELECT * FROM Accounts_Users where TrueName like '%'||varkey||'%' order by UserID;

Result := 0;

return(Result);

end;编译通过

测试数据,也没有问题。
