SQL Merge Statement Assistance - sql

Question

Good afternoon,
I'm trying to do a SQL merge with a few steps before this one.
Drop Temp Table (If it exists)
Create a temp table (Source)
USE Kronos Create table #tempGlobal --Source ( [800#] [bigint] NOT NULL, [FirstName] [varchar](20) NOT NULL, [MI] CHAR(20) NULL, [LastName] [nvarchar](30) NOT NULL, [NickName] CHAR(15) NULL, [Position] [nvarchar](50) NULL, [Department] [varchar](30) NULL, [EmployeeStatus] [char](20) NOT NULL, [CredentialDocument] VARCHAR(10) NOT NULL, [RehireDate] [date] NULL, [DateHired] [date] NOT NULL, [DateTerminated] [date] NULL)
Bulk insert from CSV into the temp table
Merge source table and target table
I don't get any job errors, but the data doesn't get updated in my test sessions.
Step 4:
` Select t.[800#], t.[FirstName], t.[MI], t.[LastName], t.[NickName], t.[Position], t.[Department], t.[EmployeeStatus], t.[CredentialDocument], t.[RehireDate], t.[DateHired], t.[DateTerminated]
From [dbo].[Employees] t --Target
Merge [dbo].[Employees] t
using [dbo].[#tempGlobal] s --Source Temp Table
on t.[800#] = s.[800#] --Stays the same even if rehired
WHEN MATCHED
AND
(
s.[LastName] <> t.[LastName]
OR s.[Position] <> t.[Position]
OR s.[Department] <> t.[Department]
OR s.[EmployeeStatus] <> t.[EmployeeStatus]
OR s.[RehireDate] <> t.[RehireDate]
OR s.[DateTerminated] <> t.[LastName]
)
THEN
UPDATE SET LastName = s.LastName,
Position = s.Position,
Department = s.Department,
EmployeeStatus = s.EmployeeStatus,
RehireDate = s.RehireDate,
DateTerminated = s.DateTerminated
WHEN NOT MATCHED --Source table doesn't match target table so we need to update the target table to match
THEN INSERT
(
[800#],
[FirstName],
[MI],
[LastName],
[NickName],
[Position],
[Department],
[EmployeeStatus],
[CredentialDocument],
[RehireDate],
[DateHired],
[DateTerminated])
VALUES
(
s.[800#],
s.FirstName,
s.MI,
s.LastName,
s.NickName,
s.Position,
s.Department,
s.EmployeeStatus,
s.CredentialDocument,
s.RehireDate,
s.DateHired,
s.DateTerminated);`
