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.
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

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.

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'

Try sp_helptext Equivalent for Tables?
https://www.sqlservercentral.com/forums/topic/script-create-table-script-from-linked-server
For Linked Servers - on SQL Server - following works great -
SELECT *

FROM MyLinkedServer.DatabaseName.dbo.TargetTable
WHERE 1 = 0
--no data transferred, but the table gets built.
You forgot to include the stored procedure or function script for sp_ppinCamposIndice
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.
http://www.codeplex.com/sqlhost/Wiki/View.aspx?title=Database%20Publishing%20Wizard
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
See my answer in this Question : How to generate create script of table using SQL query in SQL Server
Use this query :
DROP FUNCTION [dbo].[Get_Table_Script]
Go
Create Function Get_Table_Script
(
#vsTableName varchar(50)
)
Returns
VarChar(Max)
With ENCRYPTION
Begin
Declare #ScriptCommand varchar(Max)
Select #ScriptCommand =

Case

End
)

)
Then 'IDENTITY(' +
Cast( ident_seed(SO.name) As varchar ) + ',' +
Cast( ident_incr(SO.name) As varchar ) + ')'
Else ''
End
) + ' ' +
(
Case
When IS_NULLABLE = 'No'
Then 'NOT '
Else ''
End
) + 'NULL ' +
(
Case
When information_schema.columns.COLUMN_DEFAULT IS NOT NULL
Then 'DEFAULT ' + information_schema.columns.COLUMN_DEFAULT
ELse ''
End
) + ', '
From information_schema.columns
Where
( table_name = SO.name )
Order by ordinal_position
FOR XML PATH('')) o (list)
Inner Join information_schema.table_constraints As TC On (
( TC.Table_name = SO.Name )
AND
( TC.Constraint_Type = 'PRIMARY KEY' )
And
( TC.TABLE_NAME = #vsTableName )
)
Cross Apply

FOR XML PATH('')
) As j (list)
Where
( xtype = 'U' )
AND
( Name NOT IN ('dtproperties') )
Return #ScriptCommand
End
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

C: Check constraint
D: Default constraint

#ildanny : Thank you for removing the word limitation
my inferences:
Added Default and Check constraints
Changed Identity :
varchar(max) from char(1) : some tables may start from large numbers
Triggers can also be added as they are part of table, the definition
is directly available from select object_id from sys.triggers'

I would like to complete the step above with Azure Data Studio and I am not sure how to. I have previous experience with SQL Server but new to ADS interface. Help would be much appreciated! :)
Be well!
You can install the official Microsoft extension Database Administration Tool Extensions for Windows:
It adds the Generate Scripts wizard in the context menu of a selected database as in SSMS:
Please reference this tutorial: Generate data scripts using SSMS and Azure Data Studio.
We can not find any Extensions support script database as create in Azure Data Studio, it only supports script table as create with the Extension Simple Data Scripter:
For example:
Hope this helps.
With the current extensions not supporting database scripting, I have to fall back to basic 'sys' schema to achieve this. Came up with a simple query to script the 'User Defined Table' definitions alone:

Hardcoded the 'dbo' schema for now. Can be extended further with other index scenarios as well to support as a good work around for the current scenario.
Can someone help me with a tool/script that generates CREATE TABLE script for a bunch of table names that are listed either as comma separated or in an excel file.
We often have to selectively generate scripts for several tables that user submits (sometimes with no alphabetical order) and scrolling through tables & selecting checkbox in SSMS is becoming tedious. SQL Server version is 2017.
I used Profiler to see how SSMS generates so that I can tweak it to accept the list but Profiler didn't show up useful matter.
Am looking for script/tool that is fail-proof and generate the script like SSMS.

Let's suppose you have comma separated string with table names: 'tablename1, tablename2, tablename3, ..., tablenameN'.

A script for each table name can be obtained like this:
SELECT T.value AS TABLE_NAME,
dbo.FN_GET_SQL(TRIM(T.value)) AS SQL_SCRIPT
FROM string_split('tablename1, tablename2, tablename3, ..., tablenameN', ',') T
We are conducting a migration project, and looking to replace most Rowstore indexes with Clustered Columnstore indexes for large Data Warehouse. We are adding a unique index on the identity column.
Does anyone have script to alter run through all 100+ tables, and replace primary key clustered index with Columnstore Index?
Testing to see if columnstore index will help performance tuning if we migrate.
*By the way, are Identity columns recommended in Columnstore? Need way to identify each row (sometimes identity columns may reset, so placing unique constraint, Or should Guids be used?) If not identity, feel free to remove identity column with Guid or something else .
Current:
CREATE TABLE [dbo].[Fact_SalesTransaction]
(
[FactSalesTransactionId] INT IDENTITY (1, 1) NOT NULL,
[DimCustomerId] INT NOT NULL,
[DimSellerId] INT NOT NULL,
[SalesDatetime] DATETIME NULL,
[DimSalesDateId] INT NULL,
[SalesAmount] DECIMAL (28, 2) NULL,
[ETLCreateDate] DATETIME NULL,
CONSTRAINT [pk_SalesTransactionId] PRIMARY KEY CLUSTERED ([SalesTransactionId] ASC)
);
Expected:
CREATE TABLE [dbo].[Fact_SalesTransaction]
(
[FactSalesTransactionId] INT IDENTITY (1, 1) NOT NULL,
[DimCustomerId] INT NOT NULL,
[DimSellerId] INT NOT NULL,
[SalesDatetime] DATETIME NULL,
[DimSalesDateId] INT NULL,
[SalesAmount] DECIMAL (28, 2) NULL,
[ETLCreateDate] DATETIME NULL,
);
CREATE CLUSTERED COLUMNSTORE INDEX ccx_Fact_SalesTransaction ON Fact_SalesTransaction;
CREATE UNIQUE INDEX unx_FactSalesTransactionId ON dbo.Fact_SalesTransaction (FactSalesTransactionId);
We only want to use T-SQL to conduct this on an existing database.
Helpful Resource in Comment: Generate SQL Create Scripts for existing tables with Query
Devart answered this question asking about how to generate a script for a table. I tweaked his code to omit the primary key portion and replaced it with unique key and columnstore creation scripts following his general pattern. I also had to use marc_s's answer to this question about how to find out if a table's primary key is clustered or not. I put all this into a stored procedure called #scriptTable. This is what's below:
create procedure #scriptTable

#sql nvarchar(max) output

You can use #scriptTable like this:
declare #sql nvarchar(max);
exec #scriptTable 'dbo.Fact_SalesTransaction', #sql output;
print (#sql);
Replace 'print' with 'exec' or use sp_executeSql when ready.
To use it on all tables, first capture the tables you want to modify:
declare #tables table (
rowId int identity(1,1),
name nvarchar(max)
);
insert #tables
select schema_name(schema_id) + '.' + name
from sys.tables
where type_desc = 'user_table'
Now you're ready to loop the tables and apply #scriptTable:
declare #rowId int = 1;
declare #table nvarchar(max);
declare #sql nvarchar(max);
while #rowId <= (select max(rowId) from #tables) begin
select #table = name from #tables where rowId = #rowId;
exec #scriptTable #table, #sql output;
print (#sql); -- turn 'print' into 'exec' or otherwise use sp_executeSql
set #rowId += 1;
end
As before, replace 'print' with 'exec' or use sp_executeSql when ready.
Note that my portion may need further modification if you have table names that will require brackets around them.
EDIT:
Updated the code a bit to simplify (slightly) and to work with table names needing brackets around them.
For creation of CCI on all tables, you may use the below :
DECLARE #SQLscript nVARCHAR(1000) =
'CREATE CLUSTERED COLUMNSTORE INDEX &&& ON ### WITH (DROP_EXISTING = OFF,COMPRESSION_DELAY = 0)'
declare #tables table (
rowId int identity(1,1),
name nvarchar(max)
);
insert #tables
select schema_name(schema_id) + '.' + name
from sys.tables
where type_desc = 'user_table'
declare #rowId int = 1;
declare #table nvarchar(max);
declare #sql nvarchar(max);
while #rowId <= (select max(rowId) from #tables) begin
select #table = name from #tables where rowId = #rowId;
SET #SQLscript = REPLACE(REPLACE(#SQLscript, '###',#table) ,'&&&','cci_' + SUBSTRING(REPLACE(#table,'].[','_'),CHARINDEX('.',REPLACE(#table,'].[','_'))+1,LEN(REPLACE(#table,'].[','_'))))
BEGIN TRY
EXEC sp_executeSql #SQLscript;
END TRY
BEGIN CATCH
PRINT #SQLscript
END CATCH
SET #SQLscript = 'CREATE CLUSTERED COLUMNSTORE INDEX &&& ON ### WITH (DROP_EXISTING = OFF,COMPRESSION_DELAY = 0)'
set #rowId += 1;
end
The answer of #pwilcox is right, except for the last part where it spits out the code for the rowstore index. That index should not be clustered as the line above already creates the clustered columnstore index.

Example :
When code rus,output :
create table [ScrapReason] ( [Name] nvarchar(50) NOT NULL ,
[ModifiedDate] datetime NOT NULL DEFAULT (getdate()), )
ALTER TABLE ScrapReason ADD CONSTRAINT PK_ScrapReason_ScrapReasonID PRIMARY KEY ([ScrapReasonID])
There is no primary key in create table statement.
