CONVERT DATETIME TO STRING SQL HOW TO

So in the above query, we are using the Covert() function within the SELECT statement to convert the DateTime column to varchar. And for demonstration, we will take the previous sample employee table and try to convert the DateTime column to mm/dd/yyyy format. Let’s understand this conversion with the help of an example. CONVERT(VARCHAR(10), datetime_expression, 101) In SQL Server 2019, we can easily convert the DateTime data type to a string in “ mm/dd/yyyy” format by using the following syntax.

CONVERT DATETIME TO STRING SQL HOW TO

And by using the style parameter in Convert() function, we can even convert a string to different formats having milliseconds.Ĭonsider the following table, having multiple string formats with millisecond. In SQL Server, we can use the Convert() function to convert Datetime to a string with milliseconds. And after execution, it will return the following result.Ĭonverting Datetime to dd/mm/yyyy String SQL Server Convert Datetime to String with millisecond

So in the above query, we are using the approach mentioned before on a column named Joining, containing DateTime values. Now for demonstration, we are going to use the previous employee table and implementing the following query. In the end, concatenate the results of the first Convert() function with the result of Replace() function to get the desired output.After this, use the Replace() function to replace colon (:) with an empty string in hh:mm:ss string.After this, use another Convert() function to get the hh:mm:ss string from the DateTime value.First, use the SQL Server Convert() function to change the DateTime expression to yyyymmdd string format.For this purpose, a standard approach can be as follows. In SQL Server we cannot directly convert a DateTime expression to a string data type having “yyyymmddhhmmss” format. Read: SQL Server Replace Function SQL Server Convert Datetime to String yyyymmddhhmmss And we have also defined the style parameter as 113, which will return the result in “ dd Mon yyyy hh:mm:ss” format.Īfter successful execution, the query will return the following result. Lastly, we use the CONVERT() function within the SELECT statement to convert the DateTime variable to varchar(20). We have declared a DATETIME variable in the example then we have provided a value for the variable. Without stype parameter Convert() and Cas() function will return same output. The style is an optional parameter, used to define format for the resulting expression. CONVERT( data_type(length), expression, style) But the Convert() function is more efficient than the Cast() function because it has 3 parameters instead of just 2. The Convert() is another function available in SQL Server used to convert data from one data type to another data type. The query will return the follwong result.Ĭonverting Datetime to Sting using Cast() Convert() Function Lastly, we use the CAST() function within the SELECT statement to convert the DateTime variable to varchar(20). In the example above, we have declared a DATETIME variable then we have provided a value for the variable. SELECT AS varchar(20)) AS 'New String datatype' The Datatype in the syntax is the target data type that we want as a result.The expression in the above syntax can be any valid expression, variable, table column, etc.The Cast() function has the following syntax. The Cast() function in SQL Server, is used to convert a variable of one data type to another or data from one data type to another. And in this section, we’re going to discuss both the function with the help of examples. There are mainly 2 functions available in SQL Server 2019/2017, used to convert a DateTime data type to string.
