-
-
-
-**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
