• Use string as input to re.compile

  - by williamx

  I want to use a variable in a regex, like this: variables = ['variableA','variableB'] for i in range(len(variables)): regex = r"'('+variables[i]+')[:|=|\(](-?\d+(?:\.\d+)?)(?:\))?'" pattern_variable = re.compile(regex) match = re.search(pattern_variable, line) The problem is that python adds an extra backslash character for each backslash character in my regex string (ipython), and makes my regex invalid: In [76]: regex Out[76]: "'('+variables[i]+')[:|=|\\(](-?\\d+(?:\\.\\d+)?)(?:\\))?'" Any tips on how I can avoid this?

• Database-independant SQL String Concatenation in Rails

  - by Craig Walker

  I want to do a database-side string concatenation in a Rails query, and do it in database-independent way. SQL-92 specifies double-bar (||) as the concatenation operator. Unfortunately it looks like MS SQL Server doesn't support it; it uses + instead. I'm guessing that Rails' SQL grammar abstraction has solved the db-specific operator problem already. If it does exist, how do I use it?

• RowFilter including [ character in search string

  - by JeffC

  I fill a DataSet and allow the user to enter a search string. Instead of hitting the database again, I set the RowFilter to display the selected data. When the user enters a square bracket ( "[" ) I get an error "Error in Like Operator". I know there is a list of characters that need prefixed with "\" when they are used in a field name, but how do I prevent RowFilter from interpreting "[" as the beginning of a column name?

• How convert a string into a ActiveSupport::TimeWithZone?

  - by Nisanio

  How convert a string into a ActiveSupport::TimeWithZone? My dilemma is this. I need to update a field (called updated_at). The field in mysql is datetime, and the class is ActiveSupport::TimeWithZone. But the dates are strings like "10/17/2008". I used "10/17/2008".to_date (And I intend .to_time and to_datetime), and even if in console the ActiveRecord class save succesfully, the field in the database still is the current date... Thanks in advanced.

• Split String in C#

  - by ritu

  I thought this will be trivial but I can't get this to work. Assume a line in a CSV file: "Barak Obama", 48, "President", "1600 Penn Ave, Washington DC" string[] tokens = line.split(',') I expect this: "Barak Obama" 48 "President" "1600 Penn Ave, Washington DC" but the last token is 'Washington DC' not "1600 Penn Ave, Washington DC". Is there an easy way to get the split function to ignore the comma within quotes?

• Regex for finding an unterminated string

  - by Austin Hyde

  I need to search for lines in a CSV file that end in an unterminated, double-quoted string. For example: 1,2,a,b,"dog","rabbit would match whereas 1,2,a,b,"dog","rabbit","cat bird" 1,2,a,b,"dog",rabbit would not. I have very limited experience with regular expressions, and the only thing I could think of is something like "[^"]*$ However, that matches the last quote to the end of the line. How would this be done?
