Creating a table using Power Shell and SQL Server Management Objects

Review this previous post

In the above post you will get an introduction to Power Shell and SQL Server
Management Objects. You also learn how to access the SQL Server and carry out a
few tasks like listing out all the databases.

Review this post for creating a database using Power Shell and SQL Server
Management Objects:

In the above post you will learn how to create a new database in SQL Server using
SMO and Power Shell. Using Transact-SQL or the SSMS you can easily create a
database. Using PowerShell is another option to create a database using a script.

Having created a database you would want to create tables in the database.

This post shows how you may create a table. This script has been tested to work with
Power Shell ver. 4.0.

Launch SQLPS from Start | Run and type-in SQLPS and click OK.


Let us get connected to the instance of SQL Server (RegencyPark) on this computer
(Hodentek8) by (declaring) running the command shown.

PS SQLSERVER:\>  $server= new-object

Let us create a database named 'Feb6'.
Declare a name for the database as shown here:

Now create a database object variable in the instance using SMO:
PS SQLSERVER:\> $db=new-object

Now create the database using the create () function.
PS SQLSERVER:\>  $db.Create()
When you run the above command you will have created a database called Feb6 in the
SQL Server instance as shown (this may take a few seconds and you will not get any response except if there are errors) in SQL Server Management Studio:


In creating the table run the following lines of command in PS SQLSERVER:\>:

We declare a name for the table as 'SmoCustomers' and instantiate the table object
by running the following:
$tbname = "SmoCustomers"
$tb = new-object ($db, $tbname)

We assume the table to have three columns (fields) named 'Field1, Field2 and
Field3. Field1 is of int data type and the two others are nvarchar(num) data type.

Typically instantiate a column object and its data type and add that column to the
$tb.Columns. Carry out this for the three columns by running these lines in PS

$colField1 = New-Object Microsoft.SqlServer.Management.Smo.Column ($tb, "Field1")
 $colField1.DataType = [Microsoft.SqlServer.Management.Smo.Datatype]::Int

$colField2 = New-Object Microsoft.SqlServer.Management.Smo.Column ($tb, "Field2")
 $colField2.DataType = [Microsoft.SqlServer.Management.Smo.Datatype]::NVarchar(25)

$colField3 = New-Object Microsoft.SqlServer.Management.Smo.Column ($tb, "Field3")
$colField3.DataType = [Microsoft.SqlServer.Management.Smo.Datatype]::NVarchar(25)

Now create the table by running the following code:
$tb.create ()

Here is the complete line-by-line code:

Again do not look out for a response but check for the table in Feb6 database you
created earlier.
