Bulk insert not possible for tables that contain timestamp columns #255
Description
When a table contains a timestamp (rowversion) column (for optimistic concurrency) it's currently impossible to do a bulk insert as it tries to insert a value in a column that can't be assigned. This is a similar issue as with the "generated always / hidden" columns in #99
Expected behaviour:
Timestamp columns shouldn't be included in the generated insert statement or should get DEFAULT as value. See error output.
Actual behaviour:
bulk insert fails with the following error
RequestError: Cannot insert an explicit value into a timestamp column. Use INSERT with a column list to exclude the timestamp column, or insert a DEFAULT into the timestamp column.

Possible fix
When I add "|| col.type === 'timestamp'" in table.js it works but there may be a better solution?
readOnly (col) {
return (col.is_identity || col.is_computed || col.is_hidden || col.generated_always_type || col.type === 'timestamp')
}
