All files contained in this folders **must not be re-applicable**!
For this purpose we're versioning it using this format:
**File name**: yyyy_mm_dd_XX.sql
yyyy -> year
mm -> month
dd -> day
XX -> an incremental number if an sql with same date already exists, by default: 00
**SQL Header ( the first query ):**
The following is an example of the query that must be present in first row of every sql updates ( This example is specifically for auth database:)
ALTER TABLE auth_db_version
CHANGE COLUMN 2016_07_09_01
2016_07_10_00 bit;
Of course the rule is:
CHANGE COLUMN 2016_07_09_01 <- the previous version
2016_07_10_00 bit <-- the next version
Please read [this](https://github.com/azerothcore/azerothcore-wotlk/wiki/Dealing-with-SQL-files) before adding new SQL-update files.
