Symptoms

Assume that you execute a query to select data from an Oracle linked server by using a merge join in Microsoft SQL Server 2012 or SQL Server 2014. When there is a NUMBER type column that does not have a defined precision in the Oracle linked server, the query executes successfully, but some rows are missing in the result.Note This issue only occurs if the merge join is automatically selected by SQL Server.

Workaround
