special-characters

问题 Given I have the following string: This is a test {{ string.string.string }}. And try to perform the following substitution: %s/{{ [\w\.]\+ }}/substitute/g It will not work with the error: Pattern not found. When I use: %s/{{ [a-zA-Z\.]\+ }}/substitute/g It works. Is there a way to use the meta-character-classes in ranges in VIM? 回答1: You can use: A non capturing sub-expression, see :help E53 (you can use a capturing sub-expression as well, \(\) , but the overhead of capturing is useless) %s/

问题 Edit: I have about 80 characters that are causing problems in my application so I don't want to hard code a REPLACE for every single character. I think it would be easier to create a separate table with two columns,"special characters" and "replacement characters", and I will remove those columns from the original table which contains the column "StringTest". My goal will be figuring out how to use the characters table to replace characters in the string table. I am trying to replace all

问题 I have 1000 tables with more than 100000 records in each table in mysql. The tables have 300-500 columns. Some of tables have columns with special characters like .(dot) and space in the column names. Now I want to do sqoop import and create a hive table in HDFS in a single shot query like below sqoop import --connect ${domain}:${port}/$(database) --username ${username} --password ${password}\ --table $(table) -m 1 --hive-import --hive-database ${hivedatabase} --hive-table $(table) --create

问题 My App data managed by the Content Provider using CursorLoaders is in SQLite database. According to Veracode Static Scan report , it is prone to SQL Injections. But according to docs, To avoid this problem, use a selection clause that uses ? as a replaceable parameter and a separate array of selection arguments. When you do this, the user input is bound directly to the query rather than being interpreted as part of an SQL statement. Because it's not treated as SQL, the user input can't inject

问题 Hey guys, I'm thinking of ways to disable users from typing some special characters like < and >. But I would like them to use full stops and commas and question marks and exclamation marks and quotes. I've come up with this piece of code but it doesn't seem to allow any special character.: <script type="text/JavaScript"> function valid(f) { !(/^[A-zÑñ0-9]*$/i).test(f.value)?f.value = f.value.replace(/[^A-zÑñ0-9]/ig,''):null; } </script> 回答1: There are several ways of doing this, none of them

问题 I have many descriptions with special characters like é, ô and many more and have tried to remove them with: $string = str_replace("é", " ", $string) $string = ereg_replace("é", " ", $string) $string = mysql_real_escape_string($string) But nothing works, the special characters are still there and the description is not inserted in the database. I can't remove all special characters because in the description there are html tags that are needed. Thank you for any help! 回答1: Easy peasy:

问题 I have query that I run on Oracle that is supposed to allow hyphen characters. The results are supposed to match the exact String including the hyphen character as follows: SELECT <field> FROM <table> WHERE LOWER(field) LIKE '%-pa%'; The results however show "web-page", "web -page" as well as "web page". However, I only would like to find "web-page" and "web -page" in this case. I tried to escape the hyphen character with a backslash but that results in no records found. Can anybody give me a

问题 I have this java application that should load and print data with french special characters from a .dbf or dBase3 file but it doesn't work; the characters are not showing. I asked this question thinking that the problem was related only to the printing, but if you see the comments you can understand that i figured out that the problem was related to the database and not to the printing, since when adding a special character to my JTextPane, it prints normally... and i tried changing the
