Index Columns

The IndexColumns schema collection lists the indexes and their corresponding columns. By filtering on indexes, you can write more selective queries with faster query response times.

Retrieving Index Column Information

To retrieve this schema collection, call the GetSchema method of the FacebookAdsConnection class. You can restrict the results by table name. The following example retrieves the column and sequence number for each index of the Facebook Ads table AdAccounts.


String connectionString = "InitiateOAuth=GETANDREFRESH;";

using (FacebookAdsConnection conn = new FacebookAdsConnection(connectionString)) {
  DataTable databaseSchema = conn.GetSchema("IndexColumns", new string[] {"AdAccounts"});
  foreach (DataRow row in databaseSchema.Rows) {


Dim connectionString As String = "InitiateOAuth=GETANDREFRESH;"

Using conn As New FacebookAdsConnection(connectionString)
  Dim databaseSchema As DataTable = conn.GetSchema("IndexColumns",  New String() {"AdAccounts"})
  For Each row As DataRow In databaseSchema.Rows
End Using
