/*
* As of version 7 there was no equivalent to the concept of "schema"
* in SQL Server. For DatabaseMetaData functions that include
* SCHEMA_NAME drivers usually return the user name that owns the table.
*
* So the default ProbeTable method for determining the current schema
* just ends up returning the current user. If we then use that name in
* performing metadata queries our results may get filtered down to just
* objects owned by that user. So instead we report the schema name as
* null which should cause those queries to return everything.
*
* DO not use the user name here, as in MSSQL, you are able to use
* an user name and access any schema.
*
* Use an empty string, otherwise fullyqualified object name is invalid
* In MSSQL, fully qualified must include the object owner, or an empty owner
* <catalog>.<schema>.<object> e.g. mycatalog..mytable
