但这并不会触发重新编译:这两个条目引用相同的计划和查询,相同的 query_plan_hash 和query_hash 值可证明。这实际上意味着,在缓存中有两个对应于同一个批处理的计划条目,并且它强调了有必要在重复执行相同的查询时,确保影响 SET 选项的计划缓存相同,以优化计划重用,并使计划缓存大小保持在所需的最小值。
it doesn’t count the number of datepart units between the two dates. Instead, it looks at the boundaries between the units. For example, consider the following query:
While using the SQL function TIMESTAMPDIFF to compute the difference between two dates, the result was not rounded to the unit of time selected, but appears to have been truncated. For example, a date result of 32 days, 22 hours, 14 minutes was shown as 32 days. How does TIMESTAMPDIFF...
