Some of the codes are already mentioned in the above table.ĬAST() function performs the same way as CONVERT(), i.e. code: It is the date style code, the format in which we want the desired result as.In the above query, the expression should be the CURRENT_TIMESTAMP retrieved before. expr: It is an expression which 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: Some of the codes are given below to give you an overview of the formats provided by them:Īs seen above, in order to retrieve the current timestamp of the SQL server function which is used is:
However, all the codes are available on the internet easily. It is good for the coder to learn a few of them used frequently in the query to easily perform the task.In SQL, there are already defined date and time format codes ranging from 0-141 specifying the date and time values in different formats.
To convert the current timestamp in the desired date and time values, required datatype, expression, and ‘code’ (used to define the required format of date and time to be obtained) is taken as a parameter. CONVERTĬONVERT() function in SQL is used to convert any value of any data type 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 formats of date and time values. Instead, the row version is used nowadays to deal with such things.īut, here, the CURRENT_TIMESTAMP function which retrieves the current date and time values. 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/ insert in the database. In SQL, a timestamp data type also exists, which has nothing to do with the date and time values.

How to Convert Timestamp to Date in SQL with Syntax There are various functions provided in the SQL languages which allow the user to handle the above situation. So, it is important to convert the obtained timestamp in the format according to the requirements.

In SQL, CURRENT_TIMESTAMP is used to extract the current date and time. In SQL, timestamp is a function which is used to retrieve the current date and time of the SQL server without the database timezone offset.
