Мы используем SQLServer 2012-2016.Тип данных DATETIME является частью ключа во многих таблицах.когда мы выполняем запрос с помощью jdbcTemplate.query(query, queryParams, resultSetExtractor) Отправляется SQLServer: 

sp_executesql N'SELECT * FROM [schema_example].[dbo].[tbl1] 
WHERE  (dtContactGMTStartTime>@P0 OR @P1 is NULL) 
 ORDER BY dtContactGMTStartTime ASC',
N'@P0 datetime2,@P1 datetime2','2014-01-04 03:10:49.9330000','2014-01-04 03:10:49.9330000'

Тип данных параметра - DATETIME2, хотя тип данных в базе данных - DATETIME.см. задокументированная проблема в github .Кроме того, SQLServer изменил свое поведение, см. Ссылку Улучшения SQLServer в 2016 году см. Ниже пример различий между уровнями совместимости Объединение двух вышеупомянутых проблем приводит к тому, что операторы SQL получают разные строки для одного и того жеданные в разных версиях SQLServer.

Существует ли обходной путь, отличный от изменения типа данных в базе данных на DATETIME2 (3)?
