Question

I am trying to execute stored proc through SSIS and it gives me following error:

[Execute SQL Task] Error: Executing
the query “Exec sp1 ?” failed with
the following error: “Procedure: sp1
Line: 66 Message: Cannot insert
duplicate key row in object
‘table.sq1’ with unique index
‘UIX_sp1_Key’.”. Possible failure
reasons: Problems with the query,
“ResultSet” property not set
correctly, parameters not set
correctly, or connection not
established correctly.

Actually the stored Proc sp1 is truncating & reloading a data into a table.
I am not able to figure out where exactly its trying to insert duplicate record.

Thanks in advance.

Answer 1

Your data must have duplicate values across the key column(s). You could remove the primary key temporarily (or create another table with the same structure but without the definition of the primary key, but that would mean changing the stored procedure), then load the data into the table. Then use this SQL statement:

select keycol1 {,keycol2 {,keycol3} ...}, count(*)
from tablename
group by keycol1 {,keycol2 {,keycol3} ...}
having count(*) > 1

That will show you the data values that are duplicates across the key column(s).
