Orleans uses these parameters to reads query results by name and type. 8 | Vendor and deployment specific tuning is allowed and contributions are encouraged as long as the interface contract 9 | is maintained. 10 | 11 | 3) The implementation across vendor specific scripts *should* preserve the constraint names. This simplifies troubleshooting 12 | by virtue of uniform naming across concrete implementations. 13 | 14 | 5) ETag for Orleans is an opaque column that represents a unique version. The type of its actual implementation 15 | is not important as long as it represents a unique version. In this implementation we use integers for versioning 16 | 17 | 6) For the sake of being explicit and removing ambiguity, Orleans expects some queries to return either TRUE as >0 value 18 | or FALSE as =0 value. That is, affected rows or such does not matter. If an error is raised or an exception is thrown 19 | the query *must* ensure the entire transaction is rolled back and may either return FALSE or propagate the exception. 20 | Orleans handles exception as a failure and will retry. 21 | 22 | 7) The implementation follows the Extended Orleans membership protocol.

Orleans uses these parameters to reads query results by name and type. 8 | Vendor and deployment specific tuning is allowed and contributions are encouraged as long as the interface contract 9 | is maintained. 10 | 11 | 3) The implementation across vendor specific scripts *should* preserve the constraint names. This simplifies troubleshooting 12 | by virtue of uniform naming across concrete implementations. 13 | 14 | 5) ETag for Orleans is an opaque column that represents a unique version. The type of its actual implementation 15 | is not important as long as it represents a unique version. In this implementation we use integers for versioning 16 | 17 | 6) For the sake of being explicit and removing ambiguity, Orleans expects some queries to return either TRUE as >0 value 18 | or FALSE as =0 value. That is, affected rows or such does not matter. If an error is raised or an exception is thrown 19 | the query *must* ensure the entire transaction is rolled back and may either return FALSE or propagate the exception. 20 | Orleans handles exception as a failure and will retry. 21 | 22 | 7) The implementation follows the Extended Orleans membership protocol.

Orleans uses these parameters to reads query results by name and type. 8 | Vendor and deployment specific tuning is allowed and contributions are encouraged as long as the interface contract 9 | is maintained. 10 | 11 | 3) The implementation across vendor specific scripts *should* preserve the constraint names. This simplifies troubleshooting 12 | by virtue of uniform naming across concrete implementations. 13 | 14 | 5) ETag for Orleans is an opaque column that represents a unique version. The type of its actual implementation 15 | is not important as long as it represents a unique version. In this implementation we use integers for versioning 16 | 17 | 6) For the sake of being explicit and removing ambiguity, Orleans expects some queries to return either TRUE as >0 value 18 | or FALSE as =0 value. That is, affected rows or such does not matter. If an error is raised or an exception is thrown 19 | the query *must* ensure the entire transaction is rolled back and may either return FALSE or propagate the exception. 20 | Orleans handles exception as a failure and will retry. 21 | 22 | 7) The implementation follows the Extended Orleans membership protocol.

In this implementation we use integers for versioning 16 | 17 | 6) For the sake of being explicit and removing ambiguity, Orleans expects some queries to return either TRUE as >0 value 18 | or FALSE as =0 value. That is, affected rows or such does not matter. If an error is raised or an exception is thrown 19 | the query *must* ensure the entire transaction is rolled back and may either return FALSE or propagate the exception. 20 | Orleans handles exception as a failure and will retry. 21 | 22 | 7) The implementation follows the Extended Orleans membership protocol.
