There are many instances when dates and times don't show up at your doorstep in the format you'd like it to be, nor does the output of a query fit the needs of the people viewing it. One option is to format the data in the application itself. Another option is to use the built-in functions SQL Server provides to format the date string for you. This provides the current date and time according to the server providing the date and time. To change the format of the date, you convert the requested date to a string and specify the format number corresponding to the format needed. The following table is a list of SQL date formats and an example of the output. The date parameter used for all of these examples is " You can also format the date or time without dividing characters, as well as concatenate the date and time string:. If you want to get a list of all valid date and time formats, you could use the code below and change the date to GETDATE or any other date you want to use. This will output just the valid formats. Continue your learning on Microsoft SQL Server dates with these tips and tutorials which could be valuable to beginners and experienced Developers alike:. Last updated by Eric Blinn on It's the "death of a thousand small cuts". Hi George, you can do this with the format function as well.

If you've got a moment, please tell us how we can make the documentation better.

The process of changing data type of a value into another data type is referred to as data type conversion and also almost all programing languages include some type of data converting functions or functionality. When we turn our perspective to SQL Server in order to discuss details of SQL data converting operations, at first we can separate data conversion process into two parts; implicit and explicit conversions. Explicit conversion is performed explicitly by a database programmer or administrator and at the same time this conversion process is made with help of any data conversion function. This function provides a means to convert one data type to another specified data type. The default value of this parameter is

For example, this function can convert the datatype of value from integer to decimal , string to integer , integer to string , string to date and time , etc. For that use the below query. Using the above query the float value Here the INT is the target datatype and the float value is Until now, you have learned how to convert a single value from one datatype to another using only the SELECT statement. The Balance column of the table contains the float value, and you need to convert these float values into integers. So for that use the below query. After the execution of the above query, each float value of the Balance column is converted into an integer value, look at the above picture in the FloatToInt column. For example, before conversion Checking Account balance was In this SQL Server tutorial, you covered how to convert the data type of the value to different data types such as you have converted the value from integer to string, float to integer, string to date, etc.

There are many different use cases that require us to convert data between different data types nchar, nvarchar, datetime, datetime2, smalldatetime, etc. The CONVERT function is a conversion function that allows you to both convert data between different datatypes and format the result at the same time. If you require a function that is platform agnostic then you would be better off using the CAST function as it is compatible with other database platforms. Before we look at how to use the CONVERT function let us first take a look and explain the syntax of the function and make sure we understand each argument that can be passed to the function. The expression argument is the value that is to be converted and it can be any valid SQL Server expression. Finally, the style argument is an integer expression that specifies how the function will translate the expression. A complete list of styles can be found here: Style listing. The following table, taken straight from the Microsoft documentation , illustrates which data type conversions can be done implicitly and which require an explicit conversion. For conversions that do require an explicit call to the CONVERT function the best way to learn how to use the function is to look at examples. This first example shows how you can format a date returned from the getdate function which is the current date Note: you could also use a date type column and convert it to many different styles.

For more information about style values, see the Microsoft documentation. Provide product feedback. Datetime format in [yyyy-mm-dd]. If enabled, the server can use the following information that is provided in an internal DTD subset, to perform nonvalidating parse operations. Another way to convert between data types in PostgreSQL will be to use the :: characters. What is a Quiz? For example, an nchar value cannot be converted to an image value. That means that SQL Server interprets the two-digit year 49 as and the two-digit year 50 as Log in Sign Up. SQL Server Backups.

However, an nchar can be explicitly or implicitly converted to nvarchar. In that case, it's truncated. If it is invalid, an error occurs. For a list of available conversion data types, see Implicit conversions in the SQL Server documentation. Each character or byte is converted The SQL Server money data type helps to store monetary values. Follow our guided path. Net framework; otherwise, an error occurs. References Explore our selection of references covering all popular coding languages. In the following query, we will convert the money data type to varchar and we will also use style parameter of the SQL convert function. Warning Don't construct binary values, and then convert them to a data type of the numeric data type category. Instead, the operation truncates before the supplementary character.
