Here’s the simplest example of a working Merge statement I could make. Its great to build-on to test the formatting of ‘real’ merges.

drop table d, s
	
-- destination table containing old data
	create table d (id int, fruit varchar(50), tasty int)
	insert into d values (1,'apple', 5), (2,'orange', 5)
	select * from d

-- source table containing unchanged, updated, and new data
	create table s (id int, fruit varchar(50), tasty int)
	insert into s values (1, 'apple', 5), (2,'orange', 0), (3,'banana', 9) 
	select * from s

--merge statement
	merge d target
	using s source
	on target.id = source.id

	when matched then 
	update set tasty = source.tasty

	when not matched then 
	insert values (id, fruit, tasty);

-- show new destination table
	select * from d

We had this error number written multiple times into an SSIS errors table. It seems to be one of those Microsoft generic codes.

In this instance it indicated that we were using ‘fast load’ to write to a table, and one (or more) of the rows was failing.

To find the erroneous row(s), and get specific error(s), we changed to ‘normal’ load (called “Table or View”), which is fully-logged.
