Try:
Select * Into From Where 1 = 2 Note that this will not copy indexes, keys, etc.
If you want to copy the entire structure, you need to generate a Create Script of the table. You can use that script to create a new table with the same structure. You can then also dump the data into the new table if you need to.
If you are using Enterprise Manager, just right-click the table and select copy to generate a Create Script.

This is what I use to clone a table structure (columns only)...
SELECT TOP 0 * INTO NewTable FROM TableStructureIWishToClone 回答3:
Copy structure only (copy all the columns)
Select Top 0 * into NewTable from OldTable Copy structure only (copy some columns)
Select Top 0 Col1,Col2,Col3,Col4,Col5 into NewTable from OldTable Copy structure with data
Select * into NewTable from OldTable If you already have a table with same structure and you just want to copy data then use this
Insert into NewTable Select * from OldTable 回答4:
Create table abc select * from def limit 0; This will definite work

Its probably also worth mentioning that you can do the following:
Right click the table you want to duplicate > Script Table As > Create To > New Query Editor Window
Then, where is says the name of the table you just right clicked in the script that has been generated, change the name to what ever you want your new table to be called and click Execute

I don't know why you want to do that, but try:
SELECT * INTO NewTable FROM OldTable WHERE 1 = 2 It should work.

I use the following stored proc for copying a table's schema, including PK, indexes, partition status. It's not very swift, but seems to do the job. I I welcome any ideas how to speed it up:
/* Clones a table's schema from an existing table (without data) if target table exists, it will be dropped first. The following schema elements are cloned: * Structure * Primary key * Indexes * Constraints DOES NOT copy: * Triggers * File groups ASSUMPTION: constraints are uniquely named with the table name, so that we dont end up with duplicate constraint names */ CREATE PROCEDURE [dbo].[spCloneTableStructure] @SourceTable nvarchar(255), @DestinationTable nvarchar(255), @PartionField nvarchar(255), @SourceSchema nvarchar(255) = 'dbo', @DestinationSchema nvarchar(255) = 'dbo', @RecreateIfExists bit = 1 AS BEGIN DECLARE @msg nvarchar(200), @PartionScript nvarchar(255), @sql NVARCHAR(MAX) IF EXISTS(Select s.name As SchemaName, t.name As TableName From sys.tables t Inner Join sys.schemas s On t.schema_id = s.schema_id Inner Join sys.partitions p on p.object_id = t.object_id Where p.index_id In (0, 1) and t.name = @SourceTable Group By s.name, t.name Having Count(*) > 1) SET @PartionScript = ' ON [PS_PartitionByCompanyId]([' + @PartionField + '])' else SET @PartionScript = '' SET NOCOUNT ON; BEGIN TRY SET @msg =' CloneTable ' + @DestinationTable + ' - Step 1, Drop table if exists.

Found here what I was looking for. Helped me recall what I used 3-4 years back.
I wanted to reuse the same syntax to be able to create table with data resulting from the join of a table.
Came up with below query after a few attempts.
