I am trying to use the SQL Anywhere .NET 4.0 connector v12.0.1.34574, I am attempting to query out data from a legacy Sql Anywhere 7.0 system. If I just use a "SADataReader" by just poling the data out it works as normal and I get the records out fine. However if I want to get the schema of the table I am reading from, calling the following gives me a exception

SAConnectionStringBuilder sacsb = new SAConnectionStringBuilder();
sacsb.ServerName = this.diSettings.SourceServer;
sacsb.UserID = this.diSettings.SourceUsername;
sacsb.Password = this.diSettings.SourcePassword;
sacsb.DatabaseName = this.diSettings.SourceDatabase;
sacsb.AutoStart = "true";

using (var saCommand = new SACommand("Select * from TableName;", saConn))
using (var saReader = saCommand.ExecuteReader())
{
    var schemaTable = saReader.GetSchemaTable(); //Exception here
    //Snip

The error is

iAnywhere.Data.SQLAnywhere.SAException was unhandled by user code

What do I need to do to get the source table's schema? I will be moving this data to a Microsoft SQL Server 2005 database and I need to programmaticly query the column information so I can create a "mirror" table in the SQL Server database.

Using ILSpy it appears the error is comming from the following line in "SetKeyUniqueColumns(DataTable)" (string split across multiple lines for readability)

sACommand.CommandText = string.Format("
    SELECT systable.table_name, sysindex.index_id, sysindex.[unique], syscolumn.column_name 
    FROM sys.systable 
    JOIN sys.sysindex 
    JOIN sys.sysixcol 
    JOIN sys.syscolumn 
    WHERE ( ( sysindex.[unique] = 'U' ) OR ( sysindex.[unique] = 'Y' ) ) AND ( {0} ) 
    ORDER BY systable.table_name, sysindex.index_id, sysindex.[unique]", arg);

it seems the 7.0 engine does dot like the "sysindex.[unique]" in the query, is there anything I can do other than updating the database to something newer than 7.0 (I can do that but it is a last resort)
