sqlplus使用(一)
sqlplus的环境变量(来自SQL*Plus® User's Guide and Reference Release 11.2)
Parameter or Variable | Description |
---|---|
LD_LIBRARY_PATH |
Environment variable to specify the path used to search for libraries on UNIX and Linux. The environment variable may have a different name on some operating systems, such as DYLD_LIBRARY_PATH on Apple Mac OS, LIBPATH on IBM/AIX-5L, and SHLIB_PATH on HP-UX. Not applicable to Windows operating systems. Example $ORACLE_HOME/lib |
LOCAL |
Windows environment variable to specify a connection string. Performs the same function as TWO_TASK on UNIX.Windows平台下的环境变量。类似于Unix中的TWO_TASK |
NLS_LANG |
Environment variable to specify globalization behavior. Example american_america.utf8 |
ORACLE_HOME |
Environment variable to specify where SQL*Plus is installed. It is also used by SQL*Plus to specify where message files are located. Examples: d:\oracle\10g |
ORA_EDITION
指定版本
|
Environment variable to specify the database edition to use. If you specify the edition with the CONNECT or SQLPLUS command option, edition=value, it is used instead of ORA_EDITION. If no edition is specified in either the CONNECT or SQLPLUS command option, or in ORA_EDITION, SQL*Plus connects to the default edition. |
ORA_NLS10 |
Environment variable to specify the locations of the NLS data and the user boot file in SQL*Plus 10.2. The default location is $ORACLE_HOME/nls/data. In a system with both Oracle9i and 10g, or a system under version upgrade, you should set ORA_NLS10 for Oracle 10g and set ORA_NLS33 for 9i. The default NLS location in 9i was $ORACLE_HOME/common/nls/admin/data. |
ORACLE_PATH
在sqlplus执行@sql时也从这个目录中找
和下面的SQLPATH类似,SQLPATH多一个登陆加载的功能
|
Environment variable to specify the location of SQL scripts. If SQL*Plus cannot find the file in ORACLE_PATH, or if ORACLE_PATH is not set, it searches for the file in the current working directory. Not applicable to Windows
指定执行sql脚本的目录,如果不指定默认为当前工作目录
|
ORACLE_SID |
Environment variable to specify the database instance, optional |
PATH |
Environment variable to specify the path to search for executables, and DLLs in Windows. Typically includes ORACLE_HOME/bin |
SQLPATH
设置在sqlplus启动是加载login.sql文件的位置,如表格后面
在sqlplus执行@sql时也从这个目录中找
|
Environment variable or Windows registry entry to specify the location of SQL scripts. SQL*Plus searches for SQL scripts, including login.sql, in the current directory and then in the directories specified by SQLPATH, and in the subdirectories of SQLPATH directories. SQLPATH is a colon separated list of directories. There is no default value set in UNIX installations. In Windows, SQLPATH is defined in a registry entry during installation. For more information about the SQLPATH registry entry, see SQLPATH Registry Entry. |
TNS_ADMIN
指定tnsnames.ora的路径,如果不指定默认使用$ORACLE_HOME/network/admin
|
Environment variable to specify the location of the tnsnames.ora file. If not specified, $ORACLE_HOME/network/admin is used Example h:\network |
TWO_TASK |
UNIX environment variable to specify a connection string. Connections that do not specify a database will connect to the database specified in TWO_TASK.
指定默认连接的数据库,后面没有加相应的字符串的话,就去连接TWO_TASK指定的字符串
Example TWO_TASK=MYDB is the same as: sqlplus hr@MYDB 取消环境变量 export TWO_TASK='' |
