Connection Properties
You can programmatically access the information about the available connection properties and those set in the connection string by querying the ConnectionProperties schema collection.
Retrieving Connection Property Information
To retrieve the ConnectionProperties schema collection, call the GetSchema method of the SybaseIQConnection class. Access the results in the DataTable returned.
C#
DbProviderFactory provider = DbProviderFactories.GetFactory("System.Data.CData.SybaseIQ"); using(DbConnection conn = provider.CreateConnection()) { conn.Open(); DataTable databaseSchema = conn.GetSchema("ConnectionProperties"); foreach (DataRow row in databaseSchema.Rows) { Console.WriteLine(row["Name"]); Console.WriteLine(row["Type"]); Console.WriteLine(row["ShortDescription"]); } }
VB.NET
Dim provider = DbProviderFactories.GetFactory("System.Data.CData.SybaseIQ") Using conn As DbConnection = provider.CreateConnection() conn.Open() Dim databaseSchema As DataTable = conn.GetSchema("ConnectionProperties") For Each row As DataRow In databaseSchema.Rows Console.WriteLine(row("Name")) Console.WriteLine(row("Type")) Console.WriteLine(row("ShortDescription")) Next End Using
