It’s worth noting that the CAST function doesn’t modify the original data in the database. This will return the data portion of the CreatedDate for each user in the table. This is what the function returns and would look like in the following table: In this example, the OrderDateOnly column in the result set will display only the date of each order, without the accompanying time. If you wanted to retrieve a list of orders with only the date of order (without the time), you would use the following query: SELECT OrderID, CAST(OrderDate AS DATE) as OrderDateOnly The general syntax for using the CAST function to achieve this is: CAST(YourDateTimeColumn AS DATE)įor instance, consider a table named Orders with a DateTime column called OrderDate. When dealing with DateTime values, the CAST function can be particularly useful in extracting just the date portion, effectively discarding the time component. The CAST function in SQL Server is a versatile tool that allows you to convert one datatype to another. Here are some commonly used style codes for datetime conversion: When using the CONVERT function in SQL for datetime conversion, there are various style codes that you can specify to format the output. The result would be: Style Codes for the Convert Function
CONVERT DATETIME TO STRING SQL CODE
In this case, ‘103’ is the style code for “dd/mm/yyyy”. Remember, when using style codes, you need to convert to varchar, not date, because the date data type only has one format.įor example, here’s how you could display a date in the format “dd/mm/yyyy”: SELECT CONVERT(VARCHAR, GETDATE(), 103) AS 'DateOnly' In addition to converting DateTime to Date, the CONVERT function also allows you to display dates in a variety of different formats by specifying a style code. In this result, only the date is displayed, not the time. The CONVERT function takes this DateTime value and converts it to a Date format, effectively removing the time component. In this example, GETDATE() is a function that returns the current date and time.
CONVERT DATETIME TO STRING SQL HOW TO
Here’s an example that shows how to use the CONVERT function to convert a DateTime to a Date: SELECT CONVERT(DATE, GETDATE()) AS 'DateOnly' style: This is an optional parameter that allows you to specify the format of the date.expression: This is the value that you want to convert.data_type(length): This is the target data type that you want to convert to.In SQL Server, the syntax for the CONVERT function is as follows: CONVERT(data_type(length), expression, style) The CONVERT function allows you to do this by converting the DateTime value into a date format. This can come in handy when you need to display dates in a specific date format option or perform operations that require a certain date format.įor example, you might have a DateTime value that includes both the date and time, but you only want to display the date. When it comes to dates, it’s particularly useful because it allows you to take a DateTime value and convert it to a variety of different formats. The CONVERT function in SQL Server is used primarily for the conversion of one data type into another. We’ll cover some of these and how you can use them, including their performance and other considerations with SQL queries in this section. There are various methods you can use to convert DateTime into various date formats in Microsoft SQL Server and other database management systems.
