[英]getting the result of a sql statement in vs2010 vb.net
I am doing a sql statement to get all the data that starts with "A" in the database. 我正在执行一条sql语句,以获取数据库中所有以“ A”开头的数据。
Sub searchMap()
Dim connectionString As String = ConfigurationManager.ConnectionStrings("WeddingPerfectionConnectionString").ConnectionString
Dim connection As SqlConnection = New SqlConnection(connectionString)
connection.Open()
Dim sql As String = "SELECT LocationName FROM MapSearch WHERE LocationName=" Like ("1%")
Dim command As SqlCommand = New SqlCommand(sql, connection)
Dim reader As SqlDataReader = command.ExecuteReader()
Dim customerId As Integer
If (reader.Read()) Then
customerId = reader.GetValue(0)
End If
reader.Close()
End Sub
And i would like to get the result and display it in a lable. 我想得到结果并显示在标签中。
How can i go about doing it? 我该怎么做呢?
In SQL-Server: 在SQL Server中:
Dim sql As String = "SELECT LocationID, LocationName FROM MapSearch WHERE LocationName LIKE 'A%'"
