问题 I am looking for a single MYSQL script to convert ALL column names in a database to lowercase in one go... I have inherited a MYSQL database that has a lot of mixed case column names (150 tables with a strange naming convention) and I don't want to go through manually each table by table to do this. Has anyone got such a script? Thanks 回答1: You can solve this task by building a script, starting with the output from this statement: SELECT table_name, column_name, data_type FROM information

问题 Is it possible to rename/refactor a class file and have it rename the actual file on disk? If so, how can I do this? 回答1: The safest way to rename files is to refactor the class name using Xcode's "Refactor" command . Using that command makes sure that your code is also updated anywhere that references the file or the class (including NIBs). Right-click on the class name in the interface ( .h ) file, choose Refactor->Rename , and Xcode will guide you through the process, allowing you to

问题 Is there a way in R to have a variable evaluated as a column name when creating a data frame (or in similar situations like using cbind)? For example a <- "mycol"; d <- data.frame(a=1:10) this creates a data frame with one column named a rather than mycol . This is less important than the case that would help me remove quite a few lines from my code: a <- "mycol"; d <- cbind(some.dataframe, a=some.sequence) My current code has the tortured: names(d)[dim(d)[2]] <- a; which is aesthetically

问题 I'm going to need to change one of my model names. Is there anything out there that will replace every instance of the original model name in the controllers views and tests or do I have to do it all manually, page by page? 回答1: Check out RubyMine from JetBrains, they have some good refactoring tools for ruby. 回答2: You have to do all manually, page by page. If you have tests, they should give you clear indications of where it is still in use. 回答3: Netbeans has this feature, where you can give

问题 I'm trying to rename files that my program lists as having "illegal characters" for a SharePoint file importation. The illegal characters I am referring to are: ~ # % & * {} / \ | : <> ? - "" What i'm trying to do is recurse through the drive, gather up a list of filenames and then through Regular Expressions, pick out file names from a List and try to replace the invalid characters in the actual filenames themselves.

问题 This question already has answers here : How do I rename files in sub directories? (15 answers) Closed 5 years ago . I am very new to Command Prompt, and only started using it as of 1 day ago.

问题 I have a group of about 3,000 folders named XYZ-1 through XYZ-3000. Inside those folders are groups of image files and a description text file. Such as: Property123_0001.jpg Property123_0002.jpg Property123_0003.jpg ... Property123_0085.jpg Property123_0086.jpg Z_Description.txt The number of .jpg files differs in each folder, but there's always a single description file. Each directory's image files have a different name, for example `XYZ-1 might contain Property123, while XYZ-10 might
