plano - exportar tabla sql server a txt
Exportar el esquema de la base de datos en un archivo SQL (4)
¿Es posible en MS SQL Server 2008 exportar la estructura de la base de datos a un archivo T-SQL ?
Quiero exportar no solo tablas de esquema sino también claves primarias, claves externas, restricciones, índices, procedimientos almacenados, tipos / funciones definidos por el usuario.
Además, no quiero que los datos estén presentes en este archivo T-SQL .
¿Hay alguna manera de lograr eso?
¿Has probado la opción Generate Scripts (clic derecho, tareas, generar scripts) en SQL Management Studio? ¿Eso produce lo que quieres decir con un "archivo SQL"?
Escribí esta sp para crear automáticamente el esquema con todas las cosas, pk, fk, particiones, restricciones ...

Puede generar scripts en un archivo a través de SQL Server Management Studio, estos son los pasos:
- Haga clic con el botón derecho en la base de datos para la que desea generar scripts (no en la tabla) y seleccione tareas: generar scripts
- A continuación, seleccione la tabla / tablas solicitadas, vistas, procedimientos almacenados, etc. (desde seleccionar objetos específicos de la base de datos)
- Haga clic en avanzado: seleccione los tipos de datos para la secuencia de comandos
- Haga clic en Siguiente y termine
Al generar las secuencias de comandos, hay un área que le permitirá realizar secuencias de comandos, restricciones, claves, etc. Desde SQL Server 2008 R2, hay una opción avanzada en la creación de scripts:
En la imagen puedes ver. En las opciones de secuencia de comandos de conjunto, elija la última opción: Tipos de datos a la secuencia de comandos que hace clic en el lado derecho y elige lo que desea. Esta es la opción que debe elegir para exportar un esquema y datos
