Copiar la estructura completa de una tabla.

Usando algunos métodos, cuando crea una copia de una tabla, pierde índices, PK, FK, etc. Por ejemplo, en SQL Server puedo decir:

select * into dbo.table2 from dbo.table1;

Esta es solo una copia simple de la tabla; faltan todos los índices / restricciones. ¿Cómo puedo copiar una estructura de tabla (sin usar una copia de seguridad)?

Principalmente estoy buscando hacer esto manualmente, pero si eso no es posible, aceptaré cualquier solución.

Por supuesto, puede crear una tabla de secuencias de comandos relativamente fácil usando la interfaz de usuario:

Esto generará un CREATE TABLE script y solo tendrá que buscar y reemplazar el nombre antiguo con el nuevo nombre (y verificar que un objeto con el nuevo nombre ya no exista).

Pero si está tratando de automatizar esto (por ejemplo, generar el script de creación de tabla en el código), es un poco más engorroso. La opción de secuencia de comandos anterior no solo extrae todo el CREATE TABLEDDL de una sola ubicación en los metadatos; hace un montón de magia detrás de escena en el código para generar el eventualCREATE TABLE secuencia de comandos (puede usar Profiler para ver de dónde obtiene sus datos, pero no puede ver cómo los ensambla). Sugerí una opción para esto:

http://connect.microsoft.com/SQLServer/feedback/details/273934

Sin embargo, esto fue recibido con muy pocos votos y fue rápidamente derribado por Microsoft. Puede resultarle mucho más útil utilizar una herramienta de terceros para generar esquemas ( he publicado un blog sobre esto ).

En SQL Server 2012 hay nuevas funciones de metadatos que le permiten acercarse mucho más que el trabajo que tiene que hacer en 2005, 2008 y 2008 R2, juntando información de columna de los metadatos (que tiene muchas advertencias, por ejemplo si es decimal tiene que agregar la precisión / escala, si [n [var [char]] tiene que agregar la especificación de longitud, si n [var] char tiene que cortar la longitud máxima por la mitad, si es un MAX tiene que cambiar -1 a MAX, etc., etc.) En SQL Server 2012, esta parte es un poco más fácil:

SELECT name, system_type_name, is_nullable FROM
  sys.dm_exec_describe_first_result_set('select * from sys.objects', NULL, 0)

Resultados:

name                   system_type_name  is_nullable
--------------------   ----------------  -----------
name                   nvarchar(128)     0
object_id              int               0
principal_id           int               1
schema_id              int               0
parent_object_id       int               0
type                   char(2)           0
type_desc              nvarchar(60)      1
create_date            datetime          0
modify_date            datetime          0
is_ms_shipped          bit               0
is_published           bit               0
is_schema_published    bit               0

También he blogueado sobre esto.

Podría decirse que esto está mucho más cerca de su objetivo CREATE TABLE declaración que un enfoque complicado sys.columns, pero todavía hay mucho trabajo por hacer. Claves, restricciones, opciones de texto en fila, información de grupo de archivos, configuraciones de compresión, índices, etc. Es una lista muy larga y una vez más le sugiero que busque una herramienta de terceros para esto en lugar de, a riesgo de repetir un sobre analogía utilizada, reinventando la rueda.

Dicho todo esto, si necesita hacer esto a través del código pero puede hacerlo fuera de SQL Server, puede considerar SMO / PowerShell. Vea este consejo y el método Scripter.Script () .

escribí este sp para crear automáticamente el esquema con todas las cosas, pk, fk, particiones, restricciones ...

Esto podría estar usando un martillo neumático para clavar un clavo en la pared, pero dada la amplitud de la pregunta, creo que es una opción válida para mencionar.

Si usa SQL Server 2012 SP4 +, 2014 SP2 + o 2016 SP1 +, puede aprovechar DBCC CLONEDATABASEpara crear una copia de solo esquema de su base de datos sin datos. Esto es ideal para generar copias de esquemas integrales de varias tablas y puede aliviar la necesidad de "automatizar" el proceso de recorrer una serie de tablas, pero tenga en cuenta que todas las copias de tablas se crearán dentro de una nueva base de datos de solo lectura .

Estas tablas se incluyen las claves externas, las claves principales, índices y restricciones. También incluirán estadísticas y datos de almacenamiento de consultas (a menos que especifique NO_STATISTICSy NO_QUERYSTORE).

La sintaxis es

DBCC CLONEDATABASE (source_database_name, target_database_name)[WITH [NO_STATISTICS][,NO_QUERYSTORE]] 

También hay un par de advertencias más a tener en cuenta, sobre las cuales Brent Ozar tiene una excelente publicación , pero todo se reduce a cómo y por qué desea crear copias de tablas en cuanto a si alguna de las sutilezas es un factor decisivo o no. .

Puede usar el comando "Generar secuencia de comandos" en SQL Server Management Studio para obtener una secuencia de comandos que pueda crear su tabla, incluidos índices, activadores, claves foráneas, etc.

En SSMS

• Haga clic derecho en la base de datos en la que se encuentra la tabla
• Elija Tareas -> Generar guiones
• Elija "Seleccionar objetos de base de datos específicos"
• Expanda la lista "Tablas" y marque la casilla de verificación junto a la tabla que desea escribir.
• Haga clic en "Siguiente" para ir a la siguiente página del asistente
• Establezca las opciones de guardado como desee, luego haga clic en el botón "Avanzado"
• Establezca las opciones avanzadas como desee. En particular, en "Opciones de tabla / vista", tenga en cuenta que (de forma predeterminada) los índices, los desencadenantes y los índices de texto completo no tienen secuencias de comandos; si quiere esos, cámbielos de "Falso" a "Verdadero"
• Cuando termine, haga clic en "Aceptar" para guardar sus opciones avanzadas y en "Siguiente" para revisar sus selecciones. Haga clic en "Siguiente" nuevamente para generar realmente el script.

Luego puede editar para incluir justo lo que necesita en su base de datos de destino.

Aquí hay una versión basada en la de E.Mantovanelli en este hilo. Esto corrige un problema en el que un índice único no incluía la palabra clave ÚNICA en el script resultante. También agrega parámetros para que se pueda crear una tabla sin índices no agrupados o solo puede crear un script de los índices no agrupados. Lo uso para crear una tabla de etapas, cargarla, agregar los índices no agrupados y luego hacer un cambio de tabla, que permite que la carga se ejecute más rápido y los índices no están fragmentados.

--*************************************************************************************************'
--    Creates a copy of a table with optionally all indexes and constraints depending on parameters
--    Updated by : Brent Willis
--    Date Updated : 09-11-2019
--    Changes: Added the ability to create a table with clustered index and constraints only or to 
--             CREATE just the non-clustered indexes. This is helpful so a table can be created, 
--             loaded then non-clusted indexes added so it can them be swapped into a partitioned 
--             table with freshly created indexes to lower fragmentation. 
--
--             Also fixed an issue when a unique index was defined the index resulting table was not unique.
