**Oracle Study之--查看Oracle 版本运算字长（32/64位)方法**

**一、采用sqlplus查看**

**64位：**

\[oracle@rh6 ~\]$ sqlplus '/as sysdba'

SQL\*Plus: Release 11.2.0.3.0 Production on Wed Jun 24 14:14:10 2015

Connected to:  
**Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production**  
With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL>

**32位：**

\[oracle@rh55 ~\]$ !sql  
sqlplus '/as sysdba'

**SQL\*Plus: Release 11.2.0.1.0 Production on Wed Jun 24 14:20:50 2015**

Connected to an idle instance.

**二、查看version**

**64位：**

SQL> select \* from v$version;

BANNER  
\--------------------------------------------------------------------------------  
**Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production**  
PL/SQL Release 11.2.0.3.0 - Production  
CORE    11.2.0.3.0      Production  
TNS for Linux: Version 11.2.0.3.0 - Production  
NLSRTL Version 11.2.0.3.0 - Production

**32位：**

SQL> select \* from v$version;

BANNER  
\--------------------------------------------------------------------------------  
**Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production**  
PL/SQL Release 11.2.0.1.0 - Production  
CORE    11.2.0.1.0      Production  
TNS for Linux: Version 11.2.0.1.0 - Production  
NLSRTL Version 11.2.0.1.0 - Production

**如果是64位，用sqlplus 连上之后会显示具体的位数信息，32位则不会显示。**

**三、查看v$sql  
64位：**

SQL> select address from v$sql where rownum <2;

ADDRESS  
\----------------  
**00000000788E0A20**

**32位：**  
SQL> select address from v$sql where rownum <2;

ADDRESS  
\--------  
**69A9E378**

***64位输出的是16位16进制，32位输出的是8位16进制数 ***
