![]() And in the Cast() function, we have given the input expression as ’16 June 2021′, and we also want the data type to be a date. ![]() In the above query, we are using the Cast() function within the SELECT statement. ![]() SELECT CAST('16 June 2021' AS date) AS Result Now to convert a string data type to date, we can execute the following query. The Cast() function accepts 2 arguments, the first is the expression that represents a valid value, and the second is the resulting data type that a user wants. So Cast(), in SQL Server is a conversion function that is used to transform an expression from one data type to another. And we are going to discuss each function in the section below. In SQL Server, there are many conversion functions available through which we can easily convert an expression of one data type to another. It’s critical to convert this information to a date data type because dates may be more useful during analysis. When working with SQL Server, you may come across date values that are saved as strings. SQL Server Convert String to Date with the different format.SQL Server Convert String to Date in where clause.SQL Server Convert String to Date YYYYMMSSHHMMSS.SQL Server Convert String to Date yyyymm.SQL Server Convert String to Date mm/dd/yyyy.SQL Server Convert String to Date yyyymmdd.SQL Server Convert String to Date dd/mm/yyyy.Using Parse() to convert string to date.Using Convert() to convert string to date.In this tutorial, you have learned how to use the SQL Server CONVERT() function to convert a value from one type to another. This example uses the CONVERT() function to convert the current date and time to a string with a specific style: SELECT CONVERT( VARCHAR, GETDATE(), 13) result This example uses the CONVERT() function to convert the string '' to a datetime value: SELECT CONVERT(DATETIME, '') result Ĭode language: SQL (Structured Query Language) ( sql ) D) Using the CONVERT() function to convert a datetime value to a string value example C) Using the CONVERT() function to convert a string to a datetime value example Notice that the rounding and truncation behaviors of the CONVERT() function are the same as the CAST() functions’. This example uses the CONVERT() function to convert the decimal number 9.95 to another decimal number with zero scales: SELECT CAST( 9.95 AS DEC( 2, 0)) result This example uses the CONVERT() function to convert the decimal number 9.95 to an integer: SELECT CONVERT( INT, 9.95) result Ĭode language: SQL (Structured Query Language) ( sql ) B) Using the CONVERT() function to convert a decimal to another decimal with different length example A) Using the CONVERT() function to convert a decimal to an integer example Let’s take some examples of using the CONVERT() function. In contrast, the CAST() function is a part of ANSI-SQL functions, which is widely available in many other database products. The CONVERT() is similar to the CAST() function. The CONVERT() function returns the value of expression translated to the target_type with a specified style. If style is NULL, the CONVERT() function will return NULL. style is an optional integer that determines how the CONVERT() function will translate expression.expression is a valid expression of any type that will be converted.The length is optional and defaults to 30. length is an integer that specifies the length of the target type.Note that it cannot be an alias data type. ![]() target_type is the target data type to which you wan to convert the expression.The following shows the syntax of the CONVERT() function: CONVERT ( target_type, expression )Ĭode language: SQL (Structured Query Language) ( sql ) The CONVERT() function allows you to convert a value of one type to another. Introduction to SQL Server CONVERT() function Summary: in this tutorial, you will learn how to use the SQL Server CONVERT() function to convert a value of one type to another.
