SelectQueryFluentBuilder.Build(String) Method

Ends the chain of methods specified for a SelectQueryFluentBuilder.

Namespace: DevExpress.DataAccess.Sql

Assembly: DevExpress.DataAccess.v24.2.dll

Declaration

C#

public SelectQuery Build(
    string queryName
)

VB.NET

Public Function Build(
    queryName As String
) As SelectQuery

Parameters

Name	Type	Description
queryName	String	A String value, specifying the query name.

Returns

Type	Description
SelectQuery	A SelectQuery object.

Remarks

The chain of SelectQueryFluentBuilder methods must end with calling the Build method accepting the query name as a parameter.

In the following example, a query selects and orders records from a single data table.

C#

using DevExpress.DataAccess.ConnectionParameters;
using DevExpress.DataAccess.Sql;
// ... 

private SqlDataSource BindToData() {
    // Create a data source with the required connection parameters. 
    Access97ConnectionParameters connectionParameters =
    new Access97ConnectionParameters("../../Data/nwind.mdb", "", "");
    SqlDataSource ds = new SqlDataSource(connectionParameters);

    // Return a list of categories sorted by the number of products in each category. 
    // The chain ends with calling the Build method accepting the query name as a parameter.
    SelectQuery query = SelectQueryFluentBuilder
        .AddTable("Products")
        .SelectColumn("CategoryID")
        .GroupBy("CategoryID")
        .SortBy("ProductID", AggregationType.Count, System.ComponentModel.ListSortDirection.Descending)
        .Filter("[CategoryID] != 8")
        .Build("MyQuery");

    // Add the query to the collection and return the data source. 
    ds.Queries.Add(query);
    return ds;
}

VB.NET

Imports DevExpress.DataAccess.ConnectionParameters
Imports DevExpress.DataAccess.Sql
' ... 

Private Function BindToData() As SqlDataSource
    ' Create a data source with the required connection parameters.  
    Dim connectionParameters As New Access97ConnectionParameters("../../Data/nwind.mdb", "", "")
    Dim ds As New SqlDataSource(connectionParameters)

    ' Return a list of categories sorted by the number of products in each category.  
    ' The chain ends with calling the Build method accepting the query name as a parameter. 
    Dim query As SelectQuery = SelectQueryFluentBuilder.
        AddTable("Products").
        SelectColumn("CategoryID").
        GroupBy("CategoryID").
        SortBy("ProductID", AggregationType.Count, System.ComponentModel.ListSortDirection.Descending).
        Filter("[CategoryID] != 8").
        Build("MyQuery")

    ' Add the query to the collection and return the data source.  
    ds.Queries.Add(query)
    Return ds
End Function
