- COMMENTS:
-
- o The bcp_colptr() function allows you to change the program
- variable data address for a particular column while running a
- copy IN via calls to bcp_bind().
- o Initially, the program variable data address is determined when
- bcp_bind() is called. If the program variable data address
- changes between calls to bcp_sendrow(), you may call
- bcp_colptr() to reset the address of the data. The next call
- to bcp_sendrow() will use the data at the address you just set.
-
- o There must be a separate bcp_colptr() call for every column in
- the table whose data address you want to modify.
- o For information on the bcp utility program, see its manual page
- in the Commands Reference.
