Server.SetDefaultInitFields Method (Type, String[])

Specifies the properties that are fetched when objects of the specified type are instantiated.

Namespace:  Microsoft.SqlServer.Management.Smo
Assembly:  Microsoft.SqlServer.Smo (in Microsoft.SqlServer.Smo.dll)

public void SetDefaultInitFields(
	Type typeObject,
	params string[] fields


Type: System.Type
A Type system object value that specifies the type of object.
Type: System.String[]
A String array value that specifies the property fields that are to be fetched when the object is initialized.

SMO optimization allows only the minimum properties to be loaded when an object is created. When uninitialized properties are accessed, SMO makes individual requests to load the information from the instance of SQL Server. You can use this method to adjust which properties are initialized for an object when it is first created to further optimize performance.

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Reference the AdventureWorks database.
Dim db As Database
db = srv.Databases("AdventureWorks")
'Assign the Table object type to a System.Type object variable.
Dim tb As Table
Dim typ As Type
tb = New Table
typ = tb.GetType
'Assign the current default initialization fields for the Table object type to a 
'StringCollection object variable.
Dim sc As StringCollection
sc = srv.GetDefaultInitFields(typ)
'Set the default initialization fields for the Table object type to the CreateDate property.
srv.SetDefaultInitFields(typ, "CreateDate")
'Retrieve the Schema, Name, and CreateDate properties for every table in AdventureWorks.
'Note that the improvement in performance can be viewed in SQL Profiler.
For Each tb In db.Tables
    Console.WriteLine(tb.Schema + "." + tb.Name + " " + tb.CreateDate)
'Set the default initialization fields for the Table object type back to the original settings.
srv.SetDefaultInitFields(typ, sc)
