==== Explanation of SQL ====

This query will MERGE two divisions. More accurately, it sets one division inactive and sets all records using that division to the other one. It will:

  * Change GL/Ledger Records
  * Change Order and Shipping Records
  * Change Company Records
  * Move warehouses from the removed Division to the remaining division.
  * Change all inventory records for these warehouses to the new division.

===== Risk of Data Corruption if Run Improperly =====

**High**. LOTS of data is modified in this query. If run incorrectly, there is no recovery. **Back-up your data first.**  Do not run this except under the direction of a Cyrious Technical Support staff member. Doing otherwise may result in lost or contaminated data. All data modifications done through direct SQL **are permanent and non-reversable**.

<code sql>
-- This query will merge to divisions into one
-- It assumes no warehouses exist except the default ... or it will merge those too
--
DECLARE @DeletedDivision VARCHAR(30);
DECLARE @RetainedDivision VARCHAR(30);
DECLARE @DeleteWarehouses bit;
--
-- Enter the names of the deleted and retained division.
-- If you want to delete the warehouses in the deleted division and move everything into the
--    default warehouse of the reatined division, set @DeleteWarehouses = 1.  Otherwise the
--    warehouses will just be moved but not deleted.
-- Then click Run.  This should only take a few minutes to execute.
--
-- Note 1: This change is irreversible, so backup first!
-- Note 2: This query assumes Divisions have NOT been spun out in their own table.  If so, replace
--           the table EmployeeGroup with Division in all 3 queries below
