Download & Installation

You may install this procedure in your SQL Server instance by downloading (or copy-and-pasting) the script sp_GenerateTableDDLScript.sql and running it in the master database, and then use the following command to turn it into a system stored procedure, thus making it usable anywhere in the instance:

EXECUTE sp_MS_marksystemobject 'sp_GenerateTableDDLScript'

Example Usages

Example use case 1: Creating a table in an archive database, without foreign keys and identity property:

DECLARE @CMD NVARCHAR(MAX)
EXEC sp_GenerateTableDDLScript 'Sales.OrderDetails', 'ArchiveDB.Sales.OrderDetails', @CMD OUTPUT, @IncludeForeignKeys = 0, @IncludeIdentity = 0
SELECT @CMD

Example use case 2: Duplicating a table within the same database:

DECLARE @CMD NVARCHAR(MAX)
EXEC sp_GenerateTableDDLScript 'Sales.OrderDetails', 'Sales.OrderDetails_New', @CMD OUTPUT, @ConstraintsNameAppend = '_New'
SELECT @CMD

Example use case 3: Duplicating a table as a temporary table, without computed columns:

DECLARE @CMD NVARCHAR(MAX)
EXEC sp_GenerateTableDDLScript 'Sales.OrderDetails', '#temp_OrderDetails', @CMD OUTPUT, @ConstraintsNameAppend = '_Temp', @IncludeComputedColumns = 0
SELECT @CMD

Procedure Parameters

@TableName SYSNAME,			-- The name of the source table. This parameter is mandatory. If the table's schema is not default (dbo), then please specify the schema name as well as part of the parameter.
@NewTableName SYSNAME = NULL,		-- The name of the new (target) table. You may also include database and schema as part of the name. If not specified, same name as source table will be used.
@Result NVARCHAR(MAX) OUTPUT,		-- Output textual parameter that will contain the result TSQL command for creating the table.
@IncludeDefaults BIT = 1,		-- Set whether to include default constraints
@IncludeCheckConstraints BIT = 1,	-- Set whether to include check constraints
@IncludeForeignKeys BIT = 1,		-- Set whether to include foreign key constraints
@IncludeIndexes BIT = 1,		-- Set whether to include indexes
@IncludePrimaryKey BIT = 1,		-- Set whether to include primary key constraints
@IncludeIdentity BIT = 1,		-- Set whether to include identity property
@IncludeUniqueIndexes BIT = 1,		-- Set whether to include unique index constraints
@IncludeComputedColumns BIT = 1,	-- Set whether to include computed columns (if not, they will also be automatically ignored by constraints and indexes)
@UseSystemDataTypes BIT = 0,		-- Set whether to use system data type names instead of user data type names
@ConstraintsNameAppend SYSNAME = ''	-- This is an optional text string to append to constraint names, in order to avoid the duplicate object name exception. This is useful when creating the new table within the same database.
