oracle table space add ORA-01653: unable to extend table xxxxxxx by 32 in tablespace xxxxxxxxxx 解决方法添加空间： ust add a new datafile for the existing tablespace ALTER TABLESPACE LEGAL_DATA ADD DATAFILE ‘/u01/oradata/ userdata03. dbf’ SIZE 200M; To find out the location and size of your data files: SELECT FILE_NAME, BYTES FROM DBA_DATA_FILES WHERE TABLESPACE_NAME = 'LEGAL_DATA'; Are the spaces intended?

问题   is a non breaking space, which represents an empty space where no line break occurs. If I use <p> </p> I have a space between two passages (bigger break). If I use <p> </p> I only have a new line between the two passage (no break). Why? 回答1: In HTML, elements containing nothing but normal whitespace characters are considered empty. A paragraph that contains just a normal space character will have zero height. A non-breaking space is a special kind of whitespace character that isn't

writing fixed width, space delimited CSV output in Python

问题 I'm writing a program where I have to accept commands from the user like a shell where the user can set values for environment variables. The problem I'm having is if the user types set var var-value I need to know the user typed a space instead of just set and pressed enter which is a different command. How can I determine if the user pressed space or enter using scanf() ? 回答1: You'll know the user pressed enter because scanf() won't return until the user does so. If you're trying to read

Using SSH, what is the best way to remotely execute a perl file from another perl file and pass arguments that contain spaces?

Perl file on server B parses arguments n operates thereafter. Now since I won't have all parameters populated at all times, I am passing a character such as "=" appended to each parameter from CGI on server A and before processing on Server B, I chop that last character which is
