Question

我正在执行一个PL / SQL程序，但我收到错误PLS-00201：标识符＆＃39; KURTWB＆＃39;必须声明

DECLARE
create_user dba_users%ROWTYPE;
model_id varchar2(20);
user_name varchar2(20);
BEGIN
model_id:=&model_id;
user_name:=&user_name;
Select * INTO create_user from dba_users where username=model_id;
EXECUTE IMMEDIATE 'create user user_name identified by password
user_name default tablespace create_user.default_tablespace
temporary tablespace create_user.temporary_tablespace profile
create_user.profile;';
END;
/

以下是我输入的值

Enter value for model_id: kurtwb
old   6: model_id:=&model_id;
new   6: model_id:=kurtwb;
Enter value for user_name: rohit
old   7: user_name:=&user_name;
new   7: user_name:=rohit;

以下是我得到的错误

ERROR at line 6:
ORA-06550: line 6, column 11:
PLS-00201: identifier 'KURTWB' must be declared
ORA-06550: line 6, column 1:
PL/SQL: Statement ignored
ORA-06550: line 7, column 12:
PLS-00201: identifier 'ROHIT' must be declared
ORA-06550: line 7, column 1:
PL/SQL: Statement ignored

Answer 1

您已输入kurtwb作为名为&model_id的替换变量的值 SQLPLus（或Oracle-SQL-Developer`）在此行中替换此变量：

BEGIN
  model_id:=&model_id;
  ....
  ....

输入值kurtwb。替换后，代码如下所示：

BEGIN
  model_id:=kurtwb;
  ....
  ....

由于kurtwb未在任何地方定义，因此会出现PLS-00201: identifier 'KURTWB' must be declared错误。

我想您希望将kurtwb存储为model_id变量中的字符串，在这种情况下，您必须使用撇号替换变量：

BEGIN
  model_id:='&model_id';
  ....
  ....

错误PLS-00201：必须声明标识符kurtwb
