SQL to AU3 String converter


Recommended Posts

I've been doing a lot of sql queries to pull data for some automation and I got tired of manually converting my queries into strings that I can use in my scripts. "last one was 288 lines" 

This will convert either your current clipboard or a selected .sql file into an AutoIt $sSQL = "" string.

It will automatically remove any comments "not block comments though" and it should keep the formatting that you had.  I like to have my queries in a nice spacing so it's easy to tell where a sub-query starts and ends so I wanted to keep that look in the AutoIt string.

I'm sure this could be done more efficient so if you have suggestions please let me know.

Quickly browsing the posted code I've one nitpicky warning: if a literal or schema name contains two dashes, they are removed with the rest of line, destroying the SQL.

create table "dual--dash" (blah text default 'leave -- me -- alone') -- pathological table
