Question

使用VBA插入到Microsoft sql数据库中

SELECT ALL *
FROM [MarketAnalysis].[dbo].[ReviewDatabase]
WHERE [VESSEL] = 'BOATY'
  AND [LOAD DATE] BETWEEN DATEADD(day, -3,'20190227') AND DATEADD(day, +3,'20190227')
ORDER BY [ID] DESC

例如，上面，如果插入与名称和日期+/- 3天相匹配的容器，则不要再匹配，因为它与数据库中已有的东西相匹配

Answer 1

使用IF NOT EXISTS并删除ORDER BY

IF NOT EXISTS(SELECT *
FROM [MarketAnalysis].[dbo].[ReviewDatabase]
  WHERE [VESSEL] = 'BOATY'
  AND [LOAD DATE] BETWEEN DATEADD(day, -3,'20190227') AND DATEADD(day, +3,'20190227'))
BEGIN
--your insert statement
END

仅当不存在时才插入SQL数据库
