      I'm using Teiid 8.10 with h2 translator
      I have the following query containing a join with conditions separated by OR logical operator:
      select "BilanBanque"."SIGNEDDATA" as "CalculatedField1"
      from "implify_data"."Evolution_PCy_050615" "Evolution_PCy_050615"
      LEFT JOIN "implify_data"."Evolution_PCy_050615" "MidCat" ON "Evolution_PCy_050615"."ID" = "MidCat"."PID" AND ( ( ("MidCat"."Level" IN (1) ) ) )
      LEFT JOIN "implify_data"."Evolution_PCy_050615" "Data" ON ( ( ("Data"."Level" IN (2) ) ) AND ( ("Data"."PID" = "Evolution_PCy_050615"."ID") OR ("Data"."PID" = "MidCat"."ID") ) )
      LEFT JOIN "implify_data"."Sheet1_haU_010615" "BilanBanque" ON "Data"."ID" = "BilanBanque"."Account"
      where ("BilanBanque"."BankName" IN ('Bank1') )

      The corresponding JDBC query executed by Teiid contains 2 times ON after the join:
      SELECT g_3."SIGNEDDATA" FROM "implify_data"."Evolution_PCy_050615" AS g_0 LEFT OUTER JOIN "implify_data"."Evolution_PCy_050615" AS g_1 ON g_0."ID" = g_1."PID" AND g_1."Level" = 1 INNER JOIN "implify_data"."Evolution_PCy_050615" AS g_2 INNER JOIN "implify_data"."Sheet1_haU_010615" AS g_3 ON g_2."ID" = g_3."Account" ON g_2."PID" = g_0."ID" OR g_2."PID" = g_1."ID" WHERE g_2."Level" = 2 AND g_3."BankName" = 'Bank1'

      if I remove the conditions with OR from the join, the query executes with success.

      You find below the execution plan:
