linux环境使用sqlplus执行SQL脚本中文乱码处理

阅读更多关于 linux环境使用sqlplus执行SQL脚本中文乱码处理

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 某组服务器上的sqlplus在执行定时更新SQL脚本时，中文出现乱码。一开始找错了问题方向：从SQL更新脚本处理的源头开始，首先对windows下的编辑器生成的脚本文件做各种编码的尝试，然后又在vi编辑器里面进行字符编码(encoding)与文件编码(fileencoding)的各种调试。后来发现转了圈，不过并不算浪费时间，最起码对字符编码多了一些了解。我是通过如下的方法解决sqlplus执行SQL脚本出现的中文乱码问题： 1.生产环境中的字符集全是UTF8，所以对于上传至服务器上的脚本都以'UTF8 without BOM'保存 2.查看Oracle的字符集编码: SQL> select userenv('language') from dual; USERENV('LANGUAGE') ---------------------------------------------------- AMERICAN_AMERICA.AL32UTF8 SQL> 3.修改Linux的NLS_LANG环境变量，修改Oracle指定的Linux用户下面“.base_profile”文件，加入如下： export NLS_LANG="AMERICAN_AMERICA.AL32UTF8" 4.执行.bash_profile

Executable that runs a .sql file to prompt for a username to unlock in a oracle database. Needs to close at the end

阅读更多关于 Executable that runs a .sql file to prompt for a username to unlock in a oracle database. Needs to close at the end

问题 I have an executable that connects to an Oracle database and runs a SQL script, stored in a ".sql" file. When the script runs, it prompts for a username input, and then unlocks it. After it completes the unlock and it pops up: User Altered with no errors And it goes back to the sqlplus arrow. I would want the window to close after the script has run. It works perfectly on the remote server, without the connection details in the exe file. For some reason when I add the connection details in my

Can we do this globally , so that when ever we open the connection , this works > 回答1: SET NUMFORMAT is a SQL*Plus command. In general, it is a client-side setting to display the number. You could always store the SQL*Plus settings in login.sql and glogin.sql . Whenever SQL*Plus starts up, it looks for a file

sqlldr - load completion not reflected

阅读更多关于 sqlldr - load completion not reflected

问题 I have a bash script ( load_data.sh ) that invokes the sqlldr command to load data from a .csv into a table ( data_import ). On a recent invocation, I noticed that even though the command execution was completed, the table didn't contain the data from the .csv file. I say this because the subsequent statement ( process_data.sh ) in the bash script tried to run a stored procedure that threw the error ORA-01403: no data found . I learned that the commit happens right after the file load. So, I

问题 I need a bit of help with my SQL*Plus script. Is there any way I could have it so that it will accept a variable, check the table for a match and if it finds it exit the program and not continue with the rest of the accept statements? I have this code so far: ACCEPT p_cname PROMPT 'Enter Customer Name: ' DECLARE v_cname CHAR(20); BEGIN SELECT cname INTO v_cname FROM customer WHERE cname = '&p_cname'; IF v_name = '&p_cname' THEN -- Exit the program END IF; END; / -- Other ACCEPT statements if

问题 On a RedHat 6 server, a third party application requires to be root to run and needs access to sqlplus. I have a running database, I can run sqlplus as user 'oracle'. When logged in as user root, 'sqlplus usr/pwd@dbname' works as expected. The trouble is that this agent needs to run sqlplus with no parameters and it always returns ORA-12546: TNS:permission denied. I've read a dozen times that enabling root to launch Oracle is a security issue but I really have no other choice. Running Oracle
