'Usage
Dim instance As _QueryTable
Dim value As Boolean
value = instance.MaintainConnection
instance.MaintainConnection = value
bool MaintainConnection { get; set; }
Property Value
Type: System.Boolean
Remarks
You can set the MaintainConnection property only if the QueryType property of the query table or PivotTable cache is set to xlOLEDBQuery.
If you anticipate frequent queries to a server, setting this property to True might improve performance by reducing reconnection time. Setting the property to False causes an open connection to be closed.
