extract month from date in sql

When designing a database tutorial, you must note that the time field is int (11). In this way, a digital date timestamp is stored in the database, we can use the mktime function to find the timestamp of the current date and add or subtract it. The following figure shows the instance. // One month CopyCode The Code is as follows: $ lastmonth = mktime (

SQL Server Date Calculation Usually, you need to get the current date and calculate some other date, for example, your program may need to judge the first or last day of one months. Most of you probably know how to split dates (year, month, day, etc.), and then just use the

Label:SQL DateWhen we work on dates, the hardest task is to ensure that the date you insert is formatted to match the format of the date column in the database. As long as the data contains only the date parts, running the query will not be a problem. However, if time is involved, the situation is a little more complicated. Before we discuss the complexity of the

In this article, the date obtained by getdate () is composed of two parts: today's date and then time: Select getdate () Use datename () to obtain the corresponding year, month, and day, and then connect them: Select datename (year, getdate () + '-' + datename (Month, getdate () + '-' + datename (day, getdate ()) In ad

subtracting 3 milliseconds from this example on the last day of one months. One thing to keep in mind is that the time in SQL Server is exactly 3 milliseconds. That's why I need to subtract 3 milliseconds to get the date and time I want.SELECT DateAdd (Ms,-3,dateadd (mm, DATEDIFF (Mm,0,getdate ()), 0))The time portion of the calculated date contains the time at
