To trigger synchronization between two tables in Microsoft SQL Server when the source table is updated, you can use SQL Server triggers. Triggers are special stored procedures that are automatically executed or fired in response to specific events, such as INSERT, UPDATE, or DELETE operations on a table. Here's an example of how you can create a trigger to synchronize updates from a source table (SourceTable) to a destination table (DestinationTable):\ CREATE TRIGGER SyncTrigger ON SourceTable AFTER INSERT, UPDATE, DELETE AS BEGIN     SET NOCOUNT ON;     -- Check if the operation is an INSERT or UPDATE     IF EXISTS(SELECT 1 FROM inserted)     BEGIN         -- Perform synchronization for INSERT or UPDATE         MERGE INTO DestinationTable AS dest         USING inserted AS src         ON (dest.PrimaryKey = src.PrimaryKey)  -- Replace PrimaryKey with actual primary...
