     defncopy — extract procedures and views from a Microsoft server.


     defncopy [-v] [-U username] [-P password] [-S server] [-D database] [-i input_file]
              [-o output_file] [owner.object_name [owner.object_name ...]]


     defncopy is a utility program distributed with FreeTDS. It replaces a similar program of the
     same name distributed by Sybase.

     defncopy reads the text of a stored procedure or view, and writes a script suitable for
     recreating the procedure or view. For tables, it reads the output of sp_help and constructs
     a ‘CREATE TABLE’ statement, complete with ‘CREATE INDEX’, too.  owner is optional if you or
     the database owner is the owner of the procedure/view being copied.  object_name is the name
     of the system object you wish to extract.


     -U username
             database server login name.

     -P password
             database server password.

     -S server
             database server to which to connect.

     -D database
             database to use. Optional if the procedure/view being extracted is in your default

     -i input_file
             a script to apply to the database. Not currently implemented.

     -o output_file
             a file to hold the script, defaults to standard output.

     -v      Show version information and copyright notice.


     defncopy is a filter; it reads from standard input, writes to standard output, and writes
     errors to standard error. The -i, -o, and -e options override these defaults.

     defncopy makes use of the db-lib API provided by FreeTDS. This API is of course also
     available to application developers.


     defncopy exits 0 on success, and >0 if the server cannot process the query.

     defncopy will report any errors returned by the server, but will continue processing.


     defncopy first appeared in FreeTDS 0.63.

     Works only with Microsoft servers and ancient Sybase servers.  Does not create primary keys.
     Many options are defined by Sybase that this version does not implement. Feel free to
     correct this situation.  In theory, defncopy could apply/produce DDL for any system object,
     but at present only tables, procedures and views are supported, and only for extraction.
