我有一个,我连接到与Jet数据库引擎,使用VB.NET Microsoft Access数据库。我希望以编程方式获取所有的列名的特定表。
I have a Microsoft Access database that I connect to with the Jet Database Engine, using VB.NET. I want to programmatically get all of the column names for a particular table.
我想做到这一点的MS SQL语句相当于:
I would like to do the equivalent of this MS SQL statement:
SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.Columns WHERE TABLE_NAME = 'TableName'
这是可能的访问?如果不是,我有哪些选择获取的列名?
Is this possible in Access? If not, what are my options for getting the column names?
我找到了一种方法使用的在.NET连接类的getSchema 方法。
I found a way to do this using the GetSchema method of the .NET Connection class.
我写了一个返回列名特定表的方法。
I wrote a method that returns column names for a particular table.
Private Function GetColumnNamesInTable(ByVal connectionString As String, ByVal tableName As String) As List(Of String)
Dim connection As OleDbConnection = New OleDbConnection(connectionString)
Dim restrictions As String() = New String() {Nothing, Nothing, tableName, Nothing}
connection.Open()
Dim dataTable As DataTable = connection.GetSchema("Columns", restrictions)
connection.Close()
Dim returnList As List(Of String) = New List(Of String)
For Each dataRow As DataRow In dataTable.Rows
returnList.Add(dataRow("Column_Name"))
Next
Return returnList
End Function
