Ejemplo de código
Ejemplo 1 de CreateRole
Crea un rol de base de datos, editores, en una geodatabase en Oracle.
CreateRole_management("C:\Documents and Settings\administrator\Application Data\ESRI\ArcCatalog\gdb_oracle.sde", "editors", "", "")
Ejemplo 2 de CreateRole
Crea un rol de grupo de base de datos, preparadores de borradores, en una base de datos de PostgreSQL y lo otorga a los usuarios eng1 y eng2.
#Import arcpy module import arcpy CreateRole_management("C:\Documents and Settings\administrator\Application Data\ESRI\ArcCatalog\db_postg.sde", "drafters", "GRANT", "eng1,eng2")
Ejemplo 3 de CreateRole
Otorga un rol de base de datos existente, lectores, al inicio de sesión mynet\auditor en una base de datos de SQL Server.
#Import arcpy module import arcpy CreateRole_management("C:\Documents and Settings\administrator\Application Data\ESRI\ArcCatalog\db_ss.sde", "readers", "GRANT", "mynet\auditor")
Ejemplo 4 de CreateRole
Revoca el rol de base de datos, creadores, de los usuarios de la base de datos intern1, intern2 e intern3.
#Import arcpy module import arcpy CreateRole_management("D:\myconnectionfiles\mygdb.sde", "creators", "REVOKE", "intern1,intern2,intern3")
Ejemplo 5 de CreateRole
La secuencia de comandos independiente crea un rol de base de datos.
