    Description

      There is blocking issue with ODBC server. The results are corrupt due to interleaving queries running on the server.
      For a query:

      SELECT BQT1.SmallA.StringKey FROM BQT1.SmallA WHERE BQT1.SmallA.StringKey >= 47
      

      I get following result:

      relname nspname relkind
      HugeA BQT1 v
      HugeB BQT1 v
      LargeA BQT1 v
      LargeB BQT1 v
      MediumA BQT1 v
      MediumB BQT1 v
      SmallA BQT1 v
      SmallB BQT1 v
      HugeA BQT2 v
      HugeB BQT2 v
      LargeA BQT2 v
      LargeB BQT2 v
      MediumA BQT2 v
      MediumB BQT2 v
      SmallA BQT2 v

      which is a result to an internal query performed by the engine.

      See the following command log.
      Notice, that

      • j2lxLVGEBuHy.195 is the request I actually got results for
      • j2lxLVGEBuHy.200 is the requestId of my query
