Come si generano le stored procedure CRUD da una tabella in SQL Server Management Studio

Question

Come si fa a prendere una tabella e i processi CRUD memorizzati automaticamente in SSMS?

Answer 1

SSMS non ha la capacità di generare procedure CRUD. È possibile generare INSERT, UPDATE, ecc. Facendo clic con il tasto destro del mouse su Script Table As>, ma penso che avremo più fortuna con Mladen Prajdic's SSMS Tools Pack.

Answer 2

Se si utilizza Visual Studio si può fare: http://weblogs.asp.net/stevewellens/archive/2009/12/11/automatically-generate-stored-procedures-with-visual-studio.aspx

Answer 3

Ho un semplice script TSQL che uso per fare la mia. È semplice ma facilmente modificabile per soddisfare le tue esigenze. Genera TSQL per una procedura Upsert, Select ed Elimina utilizzando la tabella & visualizzazione specificata.

/* 
This is a simple, single-table CRUD Generator. It does not have a bunch of 
bells and whistles, and is easy to follow and modify. I wrote this to make 
my job easier, and I am sharing it with you to do with it as you wish. 

The Basics: 
The TSQL below will create 3 procedures: 
    1. An Upsert Procedure: Suffix _ups 
    2. A Select Procedure: Suffix _sel 
    3. A Delete Procedure: Suffix _del 

A Little More Detail: 
Things you should know: 
    All 3 procedures have a parameter called @MyID which is used to set 
    the Context, so that my audit procedures get the validated user. If you 
    Have no use for it, you'll need to remove the piece of generator code 
    that adds it as a parameter to each of the 3 procedures. You will also 
    need to remove the PRINT statement for each procedure that looks like: 

      PRINT N' SET CONTEXT_INFO @MyID;' + CHAR(13) + CHAR(10) 

    This generator expects to perform inserts, updates, and deletes on a 
    table, and selects from a view. If you want to perform selects directly 
    from the table, simply use the table name in both @TableName and 
    @ViewName. 

The Upsert Procedure: 
    If ID (Primary Key) is supplied it will perform an Update. Otherwise it 
    will perform an Insert. This generator is hard-coded to avoid inserting 
    or updating these particular fields: 
             Created 
             CreatedBy 
             Modified 
             ModifiedBy 
             RowVersion 
             <The Primary Key Field> 
    That's because in my databases I use those field names for audit, and they 
    are never modified except internally within the database. You can modify 
    the part of this procedure that performs this function to suit your needs. 

    This generator always uses the Parameter name @ID to represent the Primary 
    key defined for the table. This is my preference but you can modify to suit. 

The Select Procedure: 
    If ID (Primary Key) is supplied it will select a single row from the View 
    (Table) whose name you provide. Otherwise it will select all rows. If the 
    @ISACTIVE_SEL variable is set to 1 (True), then the Select Procedure expects 
    your View (Table) to have a bit-type field named 'IsActive'. My tables are 
    standardized to this. If @ISACTIVE_SEL = 1 the Select Procedure will have an 
    additional parameter called @IsActive (bit). When @ID is not supplied, and 
    @IsActive is not supplied, the procedure selects all rows. When @ID is not 
    supplied, and @IsActive is supplied, the procedure selects all rows where 
    the field IsActive matches the parameter @IsActive 

The Delete Procedure: 
    The Delete Pocedure requires that the Key value and the RowVersion value 
    be supplied. I use an Int type RowVersion, so if you use TimeStamp (varbinary(128)) 
    then you will need to tweak the generator.

Answer 4

Oltre agli strumenti menzionati in precedenza, c'è un altro strumento gratuito che è possibile utilizzare per completare il lavoro in pochi clic.

Per fare ciò, è necessario immettere prefisso e suffisso nella finestra delle opzioni ApexSQL Complete, in cui è possibile scegliere una delle sottoschede per ciascuno dei modelli di procedura CRUD (Seleziona, Inserisci, Aggiorna, Elimina). Al termine, la funzionalità delle procedure CRUD sarà disponibile facendo clic con il pulsante destro del mouse nella finestra Esplora oggetti, nel database o nella tabella nel menu a discesa.

Ecco un article con maggiori dettagli su questa funzionalità (articolo è un po 'vecchio, però, come caratteristica viene aggiunto nella versione corrente)
