case sensitive update

[JAagsalog]

How can you update with sensitive values?
For example
SET IDENTITY_INSERT [dbo].[LenderLevel] ON
Current value of Test ColumB is Other. It doesn't get updated with OTHER when this is run.

DECLARE @mergeOutput TABLE ( [DMLAction] VARCHAR(6) );
MERGE INTO [dbo].[Test] AS [Target]
USING (VALUES
(1,N'Branch',N'F',N'LENDERBR',N'BRANCH')
,(2,N'Mortgage Center',N'F',N'LENDERMC',N'MORTGAGE_CENTER')
,(3,N'Lender Head Office',N'F',N'LENDERHO',N'LENDER_HEAD_OFFICE')
,(4,N'Central Discharge Unit',N'F',NULL,N'CENTRAL_DISCHARGE_UNIT')
,(5,N'Region',N'F',NULL,N'REGION')
,(6,N'District',N'F',NULL,N'DISTRICT')
,(7,N'Other',N'F',NULL,N'OTHER')
) AS [Source] ([TestId],[Test],[IsDeleted],[ColumnA],[ColumnB])
ON ([Target].[TestId] = [Source].[TestId])
WHEN MATCHED AND (
NULLIF([Source].[Test], [Target].[Test]) IS NOT NULL OR NULLIF([Target].[Test], [Source].[Test]) IS NOT NULL OR
NULLIF([Source].[IsDeleted], [Target].[IsDeleted]) IS NOT NULL OR NULLIF([Target].[IsDeleted], [Source].[IsDeleted]) IS NOT NULL OR
NULLIF([Source].[ColumnA], [Target].[ColumnA]) IS NOT NULL OR NULLIF([Target].[ColumnA], [Source].[ColumnA]) IS NOT NULL OR
NULLIF([Source].[ColumnB], [Target].[ColumnB]) IS NOT NULL OR NULLIF([Target].[ColumnB], [Source].[ColumnB]) IS NOT NULL) THEN
UPDATE SET
[Target].[Test] = [Source].[Test],
[Target].[IsDeleted] = [Source].[IsDeleted],
[Target].[ColumnA] = [Source].[ColumnA],
[Target].[ColumnB] = [Source].[ColumnB]
WHEN NOT MATCHED BY TARGET THEN
INSERT([TestId],[Test],[IsDeleted],[ColumnA],[ColumnB])
VALUES([Source].[TestId],[Source].[Test],[Source].[IsDeleted],[Source].[ColumnA],[Source].[ColumnB])

Apologies for not responding to this earlier. There are a few different options:

• Skip change detection altogether by specifying the following parameter to sp_generate_merge: @update_only_if_changed=0
• Change the database (or just the relevant columns) to a case-sensitive collation e.g. SQL_Latin1_General_CP1_CS_AS
• If the source and target tables are within the same SQL instance and you don't mind adding a new column to the target table, switch to hash-based change detection by specifying the @hash_compare_column='columnName' and @include_values = 0` params
