RequiredDate BETWEEN '' AND '' Code language: SQL (Structured Query Language) ( sql )īecause the data type of the requireDate column is DATE, MySQL has to convert the literal strings: '' and '' into TIMESTAMP values before evaluating the WHERE condition. The following query retrieves the orders whose required dates are in January 2003: SELECT Let’s take a look at the orders table in the sample database: +-+ġ row in set ( 0.00 sec) Code language: PHP ( php ) 2) Using MySQL CAST function with table data examples | CONCAT( 'MySQL CAST example #',CAST( 2 AS CHAR)) | The following statement explicitly converts an integer into a string and concatenates the string with another string: SELECT CONCAT( 'MySQL CAST example #', CAST( 2 AS CHAR)) Code language: SQL (Structured Query Language) ( sql ) To explicitly convert a string into an integer, you use the CAST() function as the following statement: SELECT ( 1 + CAST( '1' AS UNSIGNED))/ 2 Code language: SQL (Structured Query Language) ( sql ) In the following example, MySQL converts a string into an integer implicitly before doing a calculation: SELECT ( 1 + '1')/ 2 Code language: SQL (Structured Query Language) ( sql )ġ row in set (0.01 sec) Code language: JavaScript ( javascript ) Let’s take a look at some examples of using the CAST() function. In practice, you often use the CAST() function to return a value with a specified type for comparison in the WHERE, JOIN, and HAVING clauses. The target type can be any one of the following types: BINARY, CHAR, DATE, DATETIME, TIME, DECIMAL, SIGNED, or UNSIGNED. The syntax of the MySQL CAST() function is as follows: CAST(expression AS TYPE) Code language: SQL (Structured Query Language) ( sql ) The CAST() function allows you to convert a value of one type into another type. Depending on the requirements and the format of the input strings, you can choose the most suitable method.Summary: in this tutorial, you will learn how to use MySQL CAST function to convert a value of a type into another type. The STR_TO_DATE(), DATE_FORMAT(), DATE(), CAST(), and CONVERT() functions are powerful tools for handling date conversions efficiently. In this blog, we explored multiple methods to convert strings to dates in MySQL. SELECT CONVERT('', DATE) AS converted_date īoth CAST() and CONVERT() functions convert the input string ' ' to a date data type. SELECT CAST('' AS DATE) AS converted_date MySQL allows explicit casting of strings to dates using either the CAST() or CONVERT() functions. Method 4: Using CAST() or CONVERT() Function The DATE() function implicitly converts the string '' to a date data type, extracting the date part and discarding the time portion (if any). MySQL can perform implicit conversions between date formats and strings using the DATE() function. Here, we first use STR_TO_DATE() to convert the string ' 08-01-2023' to a date, assuming the format is ' MM-DD-YYYY.' Then, DATE_FORMAT() is used to convert the date back to the desired format ' YYYY-MM-DD.' Method 3: Using DATE() Function with Implicit Conversion We can combine this with the STR_TO_DATE() function to achieve the desired conversion. The DATE_FORMAT() function allows us to convert a date or a string into a specific format. In this example, the format string ' %Y-%m-%d' is used to indicate that the input string should be interpreted as a date in the format " YYYY-MM-DD." The function successfully converts the string ' ' to a date data type. SELECT STR_TO_DATE('', '%Y-%m-%d') AS converted_date The function takes two arguments: the input string and the format string. MySQL provides the STR_TO_DATE() function to convert a string to a date format based on a specified format string. ![]() In this blog, we will explore multiple methods to convert strings to dates in MySQL. ![]() Converting strings to dates is crucial when dealing with date data stored as strings or importing data from external sources. Working with dates is a common task in database management, and MySQL provides powerful functions to handle date conversions.
