I'm trying to get the CREATE scripts for existing tables within SQL Server 2008. I assume I can do this by querying the sys.tables somehow, however this isn't returning me the CREATE script data.

Just CREATE TABLE or all of the other baggage, e.g indexes, relations, check constraints, triggers (With the firing order preserved!), ...? As soon as you start adding relations the order of creation becomes critical.HABO

Possible this be helpful for you. This script generate indexes, FK's, PK and common structure for any table.

For example -

DDL:

CREATE TABLE [dbo].[WorkOut](
    [WorkOutID] [bigint] IDENTITY(1,1) NOT NULL,
    [TimeSheetDate] [datetime] NOT NULL,
    [DateOut] [datetime] NOT NULL,
    [EmployeeID] [int] NOT NULL,
    [IsMainWorkPlace] [bit] NOT NULL,
    [DepartmentUID] [uniqueidentifier] NOT NULL,
    [WorkPlaceUID] [uniqueidentifier] NULL,
    [TeamUID] [uniqueidentifier] NULL,
    [WorkShiftCD] [nvarchar](10) NULL,
    [WorkHours] [real] NULL,
    [AbsenceCode] [varchar](25) NULL,
    [PaymentType] [char](2) NULL,
    [CategoryID] [int] NULL,
    [Year]  AS (datepart(year,[TimeSheetDate])),
 CONSTRAINT [PK_WorkOut] PRIMARY KEY CLUSTERED 
(
    [WorkOutID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

ALTER TABLE [dbo].[WorkOut] ADD  
CONSTRAINT [DF__WorkOut__IsMainW__2C1E8537]  DEFAULT ((1)) FOR [IsMainWorkPlace]

ALTER TABLE [dbo].[WorkOut]  WITH CHECK ADD  CONSTRAINT [FK_WorkOut_Employee_EmployeeID] FOREIGN KEY([EmployeeID])
REFERENCES [dbo].[Employee] ([EmployeeID])

ALTER TABLE [dbo].[WorkOut] CHECK CONSTRAINT [FK_WorkOut_Employee_EmployeeID]

How to Generate a CREATE TABLE Script For an Existing Table: Part 1

do you mean you wish to create a TSQL script which generates a CREATE script, or use the Management tools in SQL SERVER Management Studio to generate a Create script?

If it's the latter, it's a simply matter of right-clicking a table, and selecting Script Table As -> Create To -> New Query Window.

If you want the whole database scripted, then right click the database and select Tasks--> Generate Scripts... and then follow the wizard

otherwise it's a matter of selecting all sorts of fun things out of the various system tables.

I realize this question is old, but it recently popped up in a search I just ran, so I thought I'd post an alternative to the above answer.

If you are looking to generate create scripts programmatically in .Net, I would highly recommend looking into Server Management Objects (SMO) or Distributed Management Objects (DMO) -- depending on which version of SQL Server you are using (the former is 2005+, the latter 2000). Using these libraries, scripting a table is as easy as:

Server server      = new Server(".");
Database northwind = server.Databases["Northwind"];
Table categories   = northwind.Tables["Categories"];

StringCollection script = categories.Script();
string[] scriptArray    = new string[script.Count];

script.CopyTo(scriptArray, 0);

Here is a blog post with more information.

First of all I love the script written by devart and I wanted to use it, but I found some limitation, so I decided to improve it:

  • I fixed the bug that limits the script at 4000 chars (it's still possible that some crazy table still exceeds the limits)
  • I fixed the bug/limitation in case the table uses a nonclustered primary key
  • I replaced '[' with quotename
  • I added the name of the default constraints
  • I changed the logic to identify the source table
  • I added the possibility to drop and recreate the table and its FKs
  • I added the possibility to generate specific attributes
  • I added the support for table compression
  • I added the possibility the generate the scripts for any number of tables
  • I fixed the limitation of 4000 varchar() when printing the result
  • I replaced '' with N''
  • I added the option to generate messages during the execution, because my final script (with the insert into) can take so long that I want to know what it's doing
  • I added the generation of an "Insert into"

I didn't have time to test it properly and I tested it only on SQL Server 2012/4

The next version will change the generation of FKs because they need to be added at the end. Otherwise they may fail.

Any comment will be appreciated.

"Easiest way is to use the built-in feature of SQL Management Studio" but... I have resolved it with a function and a couple of procedures. For example, to obtain the create table for a table named 'table_name', you have to execute just the procedure called sp_ppinScriptTabla:

Exec sp_ppinScriptTabla 'table_name'

Here is the tsql script code:

Use Master
GO

Create Function sp_ppinTipoLongitud
(
    @xtype int,
    @length int,
    @isnullable int
)
Returns Varchar(512)
As 
Begin
    -- Función que a partir de un tipo de datos y una logitud, devuelve el texto del tipo.
    -- Por ejemplo: para xtype=varchar y length=10 devolverá "varchar(10)"
    Declare @ret varchar(512)
    Set @ret = ''

    Select @ret = t.name +
    Case When name in ('varchar', 'nvarchar', 'char', 'nchar') Then '(' + Convert(varchar, @length) + ')' Else '' End + ' ' +
    Case @isnullable When 1 Then 'NULL' Else 'NOT NULL' End
    From systypes t 
    Where t.xtype = @xtype

    Return @ret
End
GO

Here's a slight variation on @Devart 's answer so you can get the CREATE script for a temp table.

Please note that since the @SQL variable is an NVARCHAR(MAX) data type you might not be able to copy it from the result using just only SSMS. Please see this question to see how to get the full value of a MAX field.

Easiest way is to use the built-in feature of SQL Management Studio.

Right-click the database, go to tasks, Generate Scripts, and walk through the wizard. You can choose what objects to script, and it'll make it all for you.

Now if you are trying to make your OWN script to do the same thing, you're probably up for a lot of work...

Since we're offering alternatives to what you asked..

If you're in .Net, you should look at the Database Publishing Wizard in Visual Studio. Easy way to script your tables/data to a text file.

Use the SSMS, easiest way You can configure options for it as well (eg collation, syntax, drop...create)

Otherwise, SSMS Tools Pack, or DbFriend on CodePlex can help you generate scripts

And you can fire this Function like this :

Select [dbo].Get_Table_Script '<Your_Table_Name>'

Try this (using "Results to text"):

SELECT
ISNULL(smsp.definition, ssmsp.definition) AS [Definition]
FROM
sys.all_objects AS sp
LEFT OUTER JOIN sys.sql_modules AS smsp ON smsp.object_id = sp.object_id
LEFT OUTER JOIN sys.system_sql_modules AS ssmsp ON ssmsp.object_id = sp.object_id
WHERE
(sp.type = N'V' OR sp.type = N'P' OR sp.type = N'RF' OR sp.type=N'PC')and(sp.name=N'YourObjectName' and SCHEMA_NAME(sp.schema_id)=N'dbo')
  • C: Check constraint
  • D: Default constraint
  • F: Foreign Key constraint
  • L: Log
  • P: Stored procedure
  • PK: Primary Key constraint
  • RF: Replication Filter stored procedure
  • S: System table

And the Linked Server bit...

BEGIN

SELECT @sql = N'EXECUTE (''
SET NOCOUNT ON;
BEGIN

... Same code but be sure to double up on your single quotes

END

... code for the printmax proc (not mine, @Ben B) because it may not exist at destination server

    DECLARE @CurrentEnd BIGINT; /* track the length of the next substring */
    DECLARE @offset TINYINT; /*tracks the amount of offset needed */
    DECLARE @String NVARCHAR(MAX);
    SET @String = REPLACE(REPLACE(@sql, CHAR(13) + CHAR(10), CHAR(10)), CHAR(13), CHAR(10))

    WHILE LEN(@String) > 1
    BEGIN
        IF CHARINDEX(CHAR(10), @String) BETWEEN 1 AND 4000
        BEGIN
            SET @CurrentEnd = CHARINDEX(CHAR(10), @String) -1
            SET @offset = 2
        END
        ELSE
        BEGIN
            SET @CurrentEnd = 4000
            SET @offset = 1
        END   
        PRINT SUBSTRING(@String, 1, @CurrentEnd) 
        SET @String = SUBSTRING(@String, @CurrentEnd + @offset, LEN(@String))   
    END

END'') AT [' + @linkedservername + ']';

EXEC (@sql);

END

For LinkedServers - on SQLServer - following works great -

SELECT *

INTO MyNewTable

FROM MyLinkedServer.DatabaseName.dbo.TargetTable

WHERE 1 = 0

--no data transferred, but the table gets built.
