The CONVERT and CAST function performs the same task, the only difference being that CAST() is a part of ANSI- SQL, whereas CONVERT() is not. Thus, this function can convert the retrieved current timestamp into the date and time values. Some of the codes are already mentioned in the above table.ĬAST() function performs the same way as CONVERT(), i.e., it converts any data type’s value into the desired data type. code: The date style code is the format in which we want the desired result.In the above query, the expression should be the CURRENT_TIMESTAMP retrieved before. expr: It is an expression that needs to be converted.It can be varchar, char, bigint, smallint, datetime, binary, text, image, etc. data_type: It is the data type to convert the input expression to.Syntax of the CONVERT function of the SQL server to convert the above timestamp: convert(data_type(length), expr, code) Some of the codes are given below to give you an overview of the formats provided by them:Īs seen above, to retrieve the current timestamp of the SQL server function which is used is: CURRENT_TIMESTAMP However, all the codes are available on the internet easily. ![]() It is suitable for the coder to learn a few frequently used in the query to perform the task efficiently.There are already defined date and time format codes in SQL ranging from 0-141, specifying the date and time values in different formats.To convert the current timestamp to the desired date and time values, the required datatype, expression, and ‘code’ (used to define the required format of date and time to be obtained) are taken as a parameter. In SQL, the CONVERT () function converts any data type’s value into the required data types (as mentioned by the user in the query). In addition, SQL provides CONVERT and CAST functions that the programmer can use to perform the desired conversion task. And to convert this timestamp in the required date and time values formats. Instead, the row version is used nowadays to deal with such things.īut, here, the CURRENT_TIMESTAMP function retrieves the current date and time values. The data type timestamp has been deprecated now. ![]() Instead, it exposes the uniquely generated binary numbers in the database whose value keeps on changing on any update/inserts in the database. ![]() Hadoop, Data Science, Statistics & others How to Convert Timestamp to Date in SQL with SyntaxĪ timestamp data type also exists in SQL, which has nothing to do with the date and time values.
