OutputCacheProfile.SqlDependency Property

Gets or sets the SqlDependency property.

Namespace:  System.Web.Configuration
Assembly:  System.Web (in System.Web.dll)

[ConfigurationPropertyAttribute("sqlDependency")]
public string SqlDependency { get; set; }

Property Value

Type: System.String
The SqlDependency value.

The SqlDependency defines a relationship between a Web application and an instance of SQL Server, allowing the detection of changes in the data at the server. The SqlDependency ensures that output cached pages are removed from the cache whenever the SQL table on which they depend changes.

NoteNote

The SqlCacheDependency class monitors the table so that when the table changes, the item will be automatically removed from the Cache. This class cannot be inherited.

The following code example shows how to use the SqlDependency property.


      // Get the current SqlDependency.
      String sqlDependencyValue = 
          outputCacheProfile.SqlDependency;

      // Set the SqlDependency.
      outputCacheProfile.SqlDependency = 
          string.Empty;
