In Sybase Central, you can copy procedures between databases. To do so, select the procedures in the right pane of Sybase Central and drag it to the Procedures & Functions folder of another connected database. A new procedure is then created, and the original procedure's code is copied to it.
Note that only the procedure code is copied to the new procedure. The other procedure properties (permissions, etc.) are not copied. A procedure can be copied to the same database, provided it is given a new name.
