SQL Reformatting table columns

阅读更多关于 SQL Reformatting table columns

问题 I have a table right now which is in a very inconvenient format. Example: Columns: Quarter / ID / Sales 1 / 234 / 50 1 / 258 / 100 2 / 234 / 50 2 / 456 / 125 3 / 258 / 100 3 / 456 / 75 3 / 555 / 100 4 / 555 / 50 This is just an example, there are in reality like 5600 columns. I want to reformat the table so that the example I just showed looks more like: ID / Q1 / Q2 / Q3 / Q4 234/ 50 / 50 / 0 / 0 258/ 100 / 0 / 100 / 0 456/ 0 / 125 / 75 / 0 555/ 0 / 0 / 100 / 50 Is there a way for me to

阅读更多关于 How can you intercept pasting into a NSTextView to remove unsupported formatting?

问题 I'm trying to create a simple NSTextView-based window for simple WYSIWYG editing.
