operation.

operation. You cannot use this option with partial-width inserts.
PREVIEW option
Displays the layout of input into the destination table
including starting position, name, and data type of each column. Adaptive

This option is especially useful with partial-width inserts. It can help you
diagnose failed or skewed insertions due to incompatible data types, or
destination column alignment that does not match source columns. Look at the
expected column data type and starting position information to determine if
you need to use an insert conversion option on a column and/or where and how
much filler to use.
