Do a thing... print the parameter values for the success and failure cases and you will come to know the difference.

While inserting record into a table, always specify the number of comma seperated columns into which values are to be inserted.
eg. INSERT INTO TableName (Column1, Column2, Column3) VALUES(@Column1, @Column2, @Column3)

In your case you need to provide values for all the columns (20 if table has 20 columns).

Try specifying column name and run one more time.
