Extracting the Date from SQL Server's DateTime Data Type
Database queries often require isolating the date from a SQL Server DateTime field, leaving out the time. Several techniques can accomplish this.
One efficient approach uses the DATEADD
and DATEDIFF
functions:
SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, @your_date))
For example:
SELECT DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))
This returns:
<code>2008-09-22 00:00:00.000</code>
This method offers key benefits:
-
Avoids Data Type Conversions: No need for conversions like
varchar
todatetime
. -
Handles Locale Issues: The
DATEADD
function ensures consistent results regardless of locale settings.
The above is the detailed content of How to Extract Only the Date from a SQL Server DateTime Datatype?. For more information, please follow other related articles on the PHP Chinese website!

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
