database - Oracle PL/SQL-如何转义冒号(:)，因为Connect中的绑定(bind)变量被误解

我试图在我的一个pl/sql脚本中使用来自oracle的connect命令。
我想要实现的是能够切换到脚本内部的不同上下文（例如，以用户身份登录，然后在某个点切换到sys dba）。
我目前的做法如下：
sqlplus user/password@/数据库：1521/orcl@complete.sql
complete.sql的内容

DECLARE
     -- declare
     v_scriptInserted varchar2(1);
     v_booleanFalse varchar2(1) := '0';
BEGIN
    SELECT CASE WHEN COUNT(*) >= 1 THEN 1 ELSE 0 END INTO v_scriptInserted FROM SCHEMA_HISTORY WHERE SCRIPT = '&v_SCRIPTNAME';
       IF v_scriptInserted = booleanFalse THEN
       -- do Stuff with user privilidges and after this is done switch to sysdba
       CONNECT sys/oracle@database:1521/orcl AS SYSDBA
       -- do magic here with sysdba
       -- SWITCH CONTEXT BACK TO User
       DISCONNECT;
    END IF;
END;
/

但是，无论我如何尝试脱离连接序列，part:1521都会被误解为bind varible（sp2-0552）。
我已经在stack overflow周围搜索了一下，找到了相关的文章：
-How to escape ":" in Oracle dynamic SQL and also have bind variables?
-Oracle PL/SQL - How to escape colon (:), being misinterpreted for bind variable
不管我怎么努力，似乎都没用。
我目前的做法是：
CONNECT sys/oracle@database:1521/orcl AS SYSDBA
CONNECT sys/oracle@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=database)(PORT=1521))(CONNECT_DATA=(SID=orcl)) AS SYSDBA
CONNECT sys/oracle@database\:1521/orcl AS SYSDBA

SELECT 'sys/oracle@database' || ':' || '1521/orcl AS SYSDBA' INTO v_dest_connstring FROM DUAL;CONNECT 'v_dest_connstring'

CONNECT 'sys/oracle@database:1521/orcl AS SYSDBA'
CONNECT ''sys/oracle@database:1521/orcl AS SYSDBA''
CONNECT '''sys/oracle@database:1521/orcl AS SYSDBA'''
CONNECT "sys/oracle@database:1521/orcl AS SYSDBA"
CONNECT ""sys/oracle@database:1521/orcl AS SYSDBA""
CONNECT """sys/oracle@database:1521/orcl AS SYSDBA"""
任何帮助都是非常感谢的。
谢谢，
==============================================
编辑：
1）具有CONNECT sys/oracle@"database:1521/orcl"的想法
1.1）带“

`CONNECT sys/oracle@"database:1521/orcl" AS SYSDBA
    *
FEHLER in Zeile 16:
ORA-06550: Zeile 16, Spalte 5:
PLS-00103: Encountered the symbol "CONNECT"`

1.2）与'

CONNECT sys/oracle@'database:1521/orcl' AS SYSDBA
    *
FEHLER in Zeile 17:
ORA-06550: Zeile 17, Spalte 5:
PLS-00103: Encountered the symbol "CONNECT" when expecting one of the
following

2）由于1521是默认端口，因此将端口保留为可选端口：

CONNECT sys/oracle@database/orcl AS SYSDBA
    *
FEHLER in Zeile 17:
ORA-06550: Zeile 17, Spalte 5:
PLS-00103: Encountered the symbol "CONNECT" when expecting one of the
following

3）缺少最后一个括号，@（description=（address=（protocol=tcp）（host=database）（port=1521））（conne ct_data=（sid=orcl））作为sysdba

CONNECT sys/oracle@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=database)(PORT=1521))(CONNE‌CT_DATA=(SID=orcl))) AS SYSDBA
    *
FEHLER in Zeile 17:
ORA-06550: Zeile 17, Spalte 5:
PLS-00103: Encountered the symbol "CONNECT" when expecting one of the
following

最佳答案

CONNECT是一个sqlplus命令，不可能在pl\sql块中使用它。您必须将其从块中取出，并将其单独放入sqlplus脚本文件中（如果需要）。
