![]() However, if the function returns a different value for the same values of functions, then we can call that function to be nondeterministic. We consider a function deterministic when it returns the same value for the same parameter values. DETERMINISTIC – The function can be either deterministic or nondeterministic, which must be specified here.Once MySQL finds the RETURN statement while executing the function, the execution of the function is terminated, and the value is returned. The type of value that will be returned needs to be specified after the RETURN clause. RETURN Datatype – We can return any value from the execution of the function. ![]() BEGIN and END – BEGIN keyword marks the beginning of the function, while END marks the completion of the function in MYSQL.The function can then reference and use these modified values. IN OUT – You assign values to these parameters while calling the function, and you can modify or overwrite them inside the function.OUT – You can assign values to these parameters and override them within the function, but you cannot reference them.You cannot modify or overwrite them within the function. IN – You assign values to these parameters when you call the function, and the function can only reference and use these values.These parameters can belong to either of the three types – A process can contain none, one, or more than one parameter. parameter1, parameter2,… – We can pass the optional parameters to the functions that must be declared while creating it in the () brackets.name_of_ function – The function’s name needs to be created in MySQL.The following is the syntax of CREATE FUNCTION statement – DELIMITER $$ In this mysql tutorial we have discussed about mysql CURDATE() function with various examples.Hadoop, Data Science, Statistics & others Let’s take example-8, the below statement will return the month name from current date. Let’s take example-7, the below statement will return the day name of week from current date. Let’s take example-6, the below statement will return the week number from current date. Let’s take example-5, the below statement will return the month number from current date. ![]() ![]() SELECT YEAR(CURDATE()) Output-4 +-+Īggregate Functions MySQL |SUM, AVG, MAX, MIN, COUNT Example-5 Let’s take example-4, the below statement will return the year number from current date. Let’s take example-3, the below statement will return the Day number from current date. Let’s take example-2, the below statement will return the current date in ‘YYYYMMDD’ format. Let’s take example-1, the below statement will return the current date in ‘YYYY-MM-DD’ format. Let’s take various examples of MySQL CURDATE() function. Syntax of MySQL CURDATE Function CURDATE () Examples MySQL CURDATE() function CURRENT_DATE() is similar to CURDATE().īoth(CURRENT_DATE(), CURDATE()) functions return the current date as a value in YYYY-MM-DD or YYYYMMDD format, depending on whether the function is used in a string or numeric context. ![]() In MySQL, The CURDATE() function returns the present date in various formats, such as ‘YYYY-MM-DD’ or ‘YYYYMMDD’ format, depending on whether the numerical or string is used in the function. In our previous tutorial, we have shared a list of MySQL Date functions that are available to work with Date and time. MySQL CURDATE() function In this tutorial, we would love to share with you how to use CURDATE() MySQL function with the help of an example query.Īnd as well as, we will show you uses of mysql CURDATE() function with various MySQL functions such as YEAR(), MONTH(), WEEK(), DAYNAME(), MONTHNAME() etc.īasically CURDATE() function returns the present date in various formats, such as ‘YYYY-MM-DD’ or ‘YYYYMMDD’ format. ![]()
