In SQL Server, how do I generate a CREATE TABLE statement for a given table?

78

I've spent a good amount of time coming up with solution to this problem, so in the spirit of this post, I'm posting it here, since I think it might be useful to others.

If anyone has a better script, or anything to add, please post it.

Edit: Yes guys, I know how to do it in Management Studio - but I needed to be able to do it from within another application.

This question is tagged with sql-server scripting dynamic-sql

I've modified the version above to run for all tables and support new SQL 2005 data types. It also retains the primary key names. Works only on SQL 2005 (using cross apply).


select  'create table [' + so.name + '] (' + o.list + ')' + CASE WHEN tc.Constraint_Name IS NULL THEN '' ELSE 'ALTER TABLE ' + so.Name + ' ADD CONSTRAINT ' + tc.Constraint_Name  + ' PRIMARY KEY ' + ' (' + LEFT(j.List, Len(j.List)-1) + ')' END
from    sysobjects so
cross apply
    (SELECT 
        '  ['+column_name+'] ' + 
        data_type + case data_type
            when 'sql_variant' then ''
            when 'text' then ''
            when 'ntext' then ''
            when 'xml' then ''
            when 'decimal' then '(' + cast(numeric_precision as varchar) + ', ' + cast(numeric_scale as varchar) + ')'
            else coalesce('('+case when character_maximum_length = -1 then 'MAX' else cast(character_maximum_length as varchar) end +')','') end + ' ' +
        case when exists ( 
        select id from syscolumns
        where object_name(id)=so.name
        and name=column_name
        and columnproperty(id,name,'IsIdentity') = 1 
        ) then
        'IDENTITY(' + 
        cast(ident_seed(so.name) as varchar) + ',' + 
        cast(ident_incr(so.name) as varchar) + ')'
        else ''
        end + ' ' +
         (case when UPPER(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)
left join
    information_schema.table_constraints tc
on  tc.Table_name       = so.Name
AND tc.Constraint_Type  = 'PRIMARY KEY'
cross apply
    (select '[' + Column_Name + '], '
     FROM   information_schema.key_column_usage kcu
     WHERE  kcu.Constraint_Name = tc.Constraint_Name
     ORDER BY
        ORDINAL_POSITION
     FOR XML PATH('')) j (list)
where   xtype = 'U'
AND name    NOT IN ('dtproperties')

Update: Added handling of the XML data type

Update 2: Fixed cases when 1) there is multiple tables with the same name but with different schemas, 2) there is multiple tables having PK constraint with the same name

Here's the script that I came up with. It handles Identity columns, default values, and primary keys. It does not handle foreign keys, indexes, triggers, or any other clever stuff. It works on SQLServer 2000, 2005 and 2008.

declare @schema varchar(100), @table varchar(100)
set @schema = 'dbo' -- set schema name here
set @table = 'MyTable' -- set table name here
declare @sql table(s varchar(1000), id int identity)

-- create statement
insert into  @sql(s) values ('create table [' + @table + '] (')

-- column list
insert into @sql(s)
select 
    '  ['+column_name+'] ' + 
    data_type + coalesce('('+cast(character_maximum_length as varchar)+')','') + ' ' +
    case when exists ( 
        select id from syscolumns
        where object_name(id)[email protected]
        and name=column_name
        and columnproperty(id,name,'IsIdentity') = 1 
    ) then
        'IDENTITY(' + 
        cast(ident_seed(@table) as varchar) + ',' + 
        cast(ident_incr(@table) as varchar) + ')'
    else ''
    end + ' ' +
    ( case when IS_NULLABLE = 'No' then 'NOT ' else '' end ) + 'NULL ' + 
    coalesce('DEFAULT '+COLUMN_DEFAULT,'') + ','

 from INFORMATION_SCHEMA.COLUMNS where table_name = @table AND table_schema = @schema
 order by ordinal_position

-- primary key
declare @pkname varchar(100)
select @pkname = constraint_name from INFORMATION_SCHEMA.TABLE_CONSTRAINTS
where table_name = @table and constraint_type='PRIMARY KEY'

if ( @pkname is not null ) begin
    insert into @sql(s) values('  PRIMARY KEY (')
    insert into @sql(s)
        select '   ['+COLUMN_NAME+'],' from INFORMATION_SCHEMA.KEY_COLUMN_USAGE
        where constraint_name = @pkname
        order by ordinal_position
    -- remove trailing comma
    update @sql set s=left(s,len(s)-1) where [email protected]@identity
    insert into @sql(s) values ('  )')
end
else begin
    -- remove trailing comma
    update @sql set s=left(s,len(s)-1) where [email protected]@identity
end

-- closing bracket
insert into @sql(s) values( ')' )

-- result!
select s from @sql order by id

There is a Powershell script buried in the msdb forums that will script all the tables and related objects:

# Script all tables in a database
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO") 
    | out-null

$s = new-object ('Microsoft.SqlServer.Management.Smo.Server') '<Servername>'
$db = $s.Databases['<Database>']

$scrp = new-object ('Microsoft.SqlServer.Management.Smo.Scripter') ($s)
$scrp.Options.AppendToFile = $True
$scrp.Options.ClusteredIndexes = $True
$scrp.Options.DriAll = $True
$scrp.Options.ScriptDrops = $False
$scrp.Options.IncludeHeaders = $False
$scrp.Options.ToFileOnly = $True
$scrp.Options.Indexes = $True
$scrp.Options.WithDependencies = $True
$scrp.Options.FileName = 'C:\Temp\<Database>.SQL'

foreach($item in $db.Tables) { [email protected]($item) }
$scrp.Script($tablearray)

Support for schemas:

This is an updated version that amends the great answer from David, et al. Added is support for named schemas. It should be noted this may break if there's actually tables of the same name present within various schemas. Another improvement is the use of the official QuoteName() function.

SELECT 
    t.TABLE_CATALOG,
    t.TABLE_SCHEMA,
    t.TABLE_NAME,
    'create table '+QuoteName(t.TABLE_SCHEMA)+'.' + QuoteName(so.name) + ' (' + LEFT(o.List, Len(o.List)-1) + ');  '

For use in Management Studio:

One detractor to the sql code above is if you test it using SSMS, long statements aren't easy to read. So, as per this helpful post, here's another version that's somewhat modified to be easier on the eyes after clicking the link of a cell in the grid. The results are more readily identifiable as nicely formatted CREATE TABLE statements for each table in the db.

-- settings
DECLARE @CRLF NCHAR(2)
SET @CRLF = Nchar(13) + NChar(10)
DECLARE @PLACEHOLDER NCHAR(3)
SET @PLACEHOLDER = '{:}'

-- the main query
SELECT 
    t.TABLE_CATALOG,
    t.TABLE_SCHEMA,
    t.TABLE_NAME,
    CAST(
        REPLACE(
            'create table ' + QuoteName(t.TABLE_SCHEMA) + '.' + QuoteName(so.name) + ' (' + @CRLF 
            + LEFT(o.List, Len(o.List) - (LEN(@PLACEHOLDER)+2)) + @CRLF + ');' + @CRLF
            + CASE WHEN tc.Constraint_Name IS NULL THEN '' 
              ELSE
                'ALTER TABLE ' + QuoteName(t.TABLE_SCHEMA) + '.' + QuoteName(so.Name) 
                + ' ADD CONSTRAINT ' + tc.Constraint_Name  + ' PRIMARY KEY (' + LEFT(j.List, Len(j.List) - 1) + ');' + @CRLF
              END,
            @PLACEHOLDER,
            @CRLF
        )
    AS XML) as 'SQL_CREATE_TABLE'
FROM sysobjects so

CROSS APPLY (
    SELECT

          + '['+column_name+'] ' 
          +  data_type 
          + case data_type
                when 'sql_variant' then ''
                when 'text' then ''
                when 'ntext' then ''
                when 'decimal' then '(' + cast(numeric_precision as varchar) + ', ' + cast(numeric_scale as varchar) + ')'

                + ')','') 
            end 
        + ' ' 
        + case when exists ( 
            SELECT id 
            FROM syscolumns
            WHERE 
                object_name(id) = so.name
                and name = column_name
                and columnproperty(id,name,'IsIdentity') = 1

        + 'NULL ' 
        + case when information_schema.columns.COLUMN_DEFAULT IS NOT NULL THEN 'DEFAULT '+ information_schema.columns.COLUMN_DEFAULT 
          ELSE '' 
          END 
        + ', ' 
        + @PLACEHOLDER  -- note, can't have a field name or we'll end up with XML

    FROM information_schema.columns where table_name = so.name
    ORDER BY ordinal_position
    FOR XML PATH('')
) o (list)

LEFT JOIN information_schema.table_constraints tc on  
    tc.Table_name = so.Name
    AND tc.Constraint_Type  = 'PRIMARY KEY'

LEFT JOIN information_schema.tables t on  
    t.Table_name = so.Name

CROSS APPLY (
    SELECT QUOTENAME(Column_Name) + ', '
    FROM information_schema.key_column_usage kcu
    WHERE kcu.Constraint_Name = tc.Constraint_Name
    ORDER BY ORDINAL_POSITION
    FOR XML PATH('')
) j (list)

WHERE
    xtype = 'U'
    AND name NOT IN ('dtproperties')
    -- AND so.name = 'ASPStateTempSessions'
;

Not to belabor the point, but here's the functionally equivalent example outputs for comparison:

-- 1 (scripting version)
create table [dbo].[ASPStateTempApplications] (  [AppId] int  NOT NULL ,  [AppName] char(280)  NOT NULL );  ALTER TABLE [dbo].[ASPStateTempApplications] ADD CONSTRAINT PK__ASPState__8E2CF7F908EA5793 PRIMARY KEY  ([AppId]);  

-- 2 (SSMS version)
create table [dbo].[ASPStateTempSessions] (
   [SessionId] nvarchar(88)  NOT NULL , 
   [Created] datetime  NOT NULL DEFAULT (getutcdate()), 
   [Expires] datetime  NOT NULL , 
   [LockDate] datetime  NOT NULL , 
   [LockDateLocal] datetime  NOT NULL , 
   [LockCookie] int  NOT NULL , 
   [Timeout] int  NOT NULL , 
   [Locked] bit  NOT NULL , 
   [SessionItemShort] varbinary(7000)  NULL , 
   [SessionItemLong] image(2147483647)  NULL , 
   [Flags] int  NOT NULL DEFAULT ((0))
);
ALTER TABLE [dbo].[ASPStateTempSessions] ADD CONSTRAINT PK__ASPState__C9F4929003317E3D PRIMARY KEY ([SessionId]);

..

Detracting factors:

It should be noted that I remain relatively unhappy with this due to the lack of support for indeces other than a primary key. It remains suitable for use as a mechanism for simple data export or replication.

If the application you are generating the scripts from is a .NET application, you may want to look into using SMO (Sql Management Objects). Reference this SQL Team link on how to use SMO to script objects.

I'm going to improve the answer by supporting partitioned tables:

find partition scheme and partition key using below scritps:

declare @partition_scheme varchar(100) = (
select distinct ps.Name AS PartitionScheme
from sys.indexes i  
join sys.partitions p ON i.object_id=p.object_id AND i.index_id=p.index_id  
join sys.partition_schemes ps on ps.data_space_id = i.data_space_id  
where i.object_id = object_id('your table name')
)
print @partition_scheme

declare @partition_column varchar(100) = (
select c.name 
from  sys.tables          t
join  sys.indexes         i 
      on(i.object_id = t.object_id 
  and i.index_id < 2)
join  sys.index_columns  ic 
  on(ic.partition_ordinal > 0 
  and ic.index_id = i.index_id and ic.object_id = t.object_id)
join  sys.columns         c 
  on(c.object_id = ic.object_id 
  and c.column_id = ic.column_id)
where t.object_id  = object_id('your table name')
)
print @partition_column

then change the generation query by adding below line at the right place:

+ IIF(@partition_scheme is null, '', 'ON [' + @partition_scheme + ']([' + @partition_column + '])')

Credit due to @Blorgbeard for sharing his script. I'll certainly bookmark it in case I need it.

Yes, you can "right click" on the table and script the CREATE TABLE script, but:

  • The a script will contain loads of cruft (interested in the extended properties anyone?)
  • If you have 200+ tables in your schema, it's going to take you half a day to script the lot by hand.

With this script converted into a stored procedure, and combined with a wrapper script you would have a nice automated way to dump your table design into source control etc.

The rest of your DB code (SP's, FK indexes, Triggers etc) would be under source control anyway ;)

Something I've noticed - in the INFORMATION_SCHEMA.COLUMNS view, CHARACTER_MAXIMUM_LENGTH gives a size of 2147483647 (2^31-1) for field types such as image and text. ntext is 2^30-1 (being double-byte unicode and all).

This size is included in the output from this query, but it is invalid for these data types in a CREATE statement (they should not have a maximum size value at all). So unless the results from this are manually corrected, the CREATE script won't work given these data types.

I imagine it's possible to fix the script to account for this, but that's beyond my SQL capabilities.

Show create table in classic asp (handles constraints, primary keys, copying the table structure and/or data ...)

Sql server Show create table Mysql-style "Show create table" and "show create database" commands from Microsoft sql server. The script is written is Microsoft asp-language and is quite easy to port to another language.*

I realise that it's been a very long time but thought I'd add anyway. If you just want the table, and not the create table statement you could use

select into x from db.schema.y where 1=0

to copy the table to a new DB

To combine drop table (if exists) with create use like this:

SELECT Drop_Table + CHAR(10) + Create_Table FROM SysCreateTables
