PrepareInstancePageQueryCommand Method

Summary

Initializes a System.Data.IDbCommand object to query for Composite Instance information using matching parameters for pagination.

Syntax

C++

protected override void PrepareInstancePageQueryCommand( 
   IDbCommand command, 
   Collection<CatalogElement[]> matchingParamsCollection, 
   QueryPageInfo queryPageInfo 
)

Protected Overrides Sub PrepareInstancePageQueryCommand( 
   ByVal command As System.Data.IDbCommand, 
   ByVal matchingParamsCollection As System.Collections.ObjectModel.Collection(Of Leadtools.Medical.DataAccessLayer.Catalog.CatalogElement() 
), 
   ByVal queryPageInfo As QueryPageInfo)

protected:  
   virtual void PrepareInstancePageQueryCommand( 
      System::Data::IDbCommand^ command, 
      System::Collections::ObjectModel::Collection<array<Leadtools::Medical::DataAccessLayer::Catalog::CatalogElement^>^>^ matchingParamsCollection, 
      QueryPageInfo^ queryPageInfo 
   ) override

Parameters

command

Type: System.Data.IDbCommand

The database command that will be initialized to execute the query.

matchingParamsCollection

Type: Collection of CatalogElement Array

The matching parameters for the query.

queryPageInfo

Type: QueryPageInfo

Specifies the page number and page size that will result from the executing the query.

Remarks

This is similar to the PrepareInstancePageQueryCommand method, except that the query will generate paginated results. The queryPageInfo is used to specify a page number and page size for the results. For example, suppose that the executing the query returns 100 rows. If queryPageInfo specifies a page size of 10, and a page number of 3. Executing the query will then return 10 total rows (the page size) starting with row 30 (PageNumber * PageSize). Therefore, the result would be rows 30 through 40.
