Note that SQL Server does not return the number of full months between two datetimes, it calculates the difference between the month and year parts only. SQL Server: -- Get difference in months (1 day is actual difference between 2 dates below) SELECT DATEDIFF(month, '2023-12-31', '...
注意BETWEEN认为终点值是包含在范围内的。 NOT BETWEEN可以做相反比较: a NOT BETWEEN x AND y 等效于 a < x OR a > y BETWEEN SYMMETRIC和BETWEEN相似,不过BETWEEN SYMMETRIC不要求AND左边的参数小于或等于右边的参数。如果左参数不是小于等于右参数,这两个参数会自动被交换,这样总是会应用一个非空范围。 当...

Two values in table “pro_scouting_reports” were seen to be missing, thus preventing the creation of a number of Foreign Key constraints: 1 2 3 # example values detected during the testing phase 921 4714 These two INSERT statements permit the creation of the FK constraints: 1 2 3 4 5 ...

Again, for production code you might want to clarify what's going on a little here using a subquery (although since we've hard-coded the number of months, putting this into production is unlikely!). A tidied-up version might look like: select name, initialoutlay / (monthlyrevenue - ...
Remember thatDATE/INTEGERSare calculated as the number of days but not in months, years, or other units of time. Many people would tend to implement theDATEDIFFandDATEADDfunctions to PostgreSQL in its extensions. Here, you may even be able to use them if all else fails. ...
TIMESTAMP and TIMESTAMPTZ supports microsecond precision. However, there is an option for “rounding” of fractional digits for the seconds component. To do this, we can specify a number between 0 and 6 inclusive in parenthesis after TIMESTAMP and TIMESTAMPTZ, e.g.TIMESTAMP(3)for TIMESTAMP...
