create SQL Server table based on a user defined ty

Question

I have my defined table type created with

CREATE TYPE dbo.MyTableType AS TABLE
(
    Name      varchar(10) NOT NULL,
    ValueDate date        NOT NULL,
    TenorSize smallint    NOT NULL,
    TenorUnit char(1)     NOT NULL,
    Rate      float       NOT NULL
    PRIMARY KEY (Name, ValueDate, TenorSize, TenorUnit)
);

and I would like to create a table of this type. From this answer the suggestion was to try

CREATE TABLE dbo.MyNewTable AS dbo.MyTableType

which produced the following error message in my SQL Server Express 2012:

Incorrect syntax near the keyword 'OF'.

Is this not supported by SQL Server Express? If so, could I create it some other way, for example using DECLARE?

Answer 1

--Create table variable from type.
DECLARE @Table AS dbo.MyTableType

--Create new permanent/physical table by selecting into from the temp table.
SELECT *
INTO dbo.NewTable
FROM @Table
WHERE 1 = 2

--Verify table exists and review structure.
SELECT *
FROM dbo.NewTable

Table type is a template. You need to use this object to create a table. The readonly is the only option you have.

Create proc NewT @x MyTableType readonly as Select * from @x

Now you can list the columns in the instantiated table calling the stored procedure. Exec NewT

It is just like an other datetype in your sql server. Creating a Table of a user defined type there is no such thing in sql server. What you can do is Declare a variable of this type and populate it but you cant create a table of this type.

Something like this...

/* Declare a variable of this type */

DECLARE @My_Table_Var AS dbo.MyTableType;

/* Populate the table with data */

INSERT INTO @My_Table_Var 
SELECT Col1, Col2, Col3 ,.....
FROM Source_Table

IN sql server use the following syntax to copy the table

SELECT * INTO newtablename FROM oldtablename;
