The following code example shows how to create a table from user-defined data types.

C#

Server srv = new Server("(local)");
Database db = srv.Databases("AdventureWorks2008R2");
Schema schema1 = new Schema(db, "schema1");
schema1.Create();

UserDefinedDataType uddt = new UserDefinedDataType(db, "uddt");
uddt.SystemType = "int";
uddt.Create();

UserDefinedDataType uddt1 = new UserDefinedDataType(db, "uddt1");
uddt1.Schema = "schema1";
uddt1.SystemType = "int";
uddt1.Create();

UserDefinedDataType uddt2 = new UserDefinedDataType(db, "uddt2", "schema1");
uddt2.SystemType = "nvarchar";
uddt2.Length = 90;
uddt2.Create();

Table table = new Table(db, "mytable");
table.Columns.Add((new Column(table, "c1", Microsoft.SqlServer.Management.Smo.DataType.NVarChar(100))));
table.Columns.Add((new Column(table, "c2", Microsoft.SqlServer.Management.Smo.DataType.UserDefinedDataType("uddt"))));
Column c = new Column(table, "c3");
c.DataType = new DataType(SqlDataType.UserDefinedDataType, "uddt1", "schema1");
table.Columns.Add(c);
Column c1 = new Column(table, "c4");
c1.DataType = new DataType(uddt);
table.Columns.Add(c1);
DataType dt = new DataType(uddt2); 
Column c2 = new Column(table, "c5");
c2.DataType = dt;
table.Columns.Add(c2);
table.Create();

PowerShell
