In this tutorial, you have learned how to use the CAST() and TO_DATE() functions to convert a string to a date in SQL. Notice that the date format must be corresponding to the date string as specified in the statement DD MON YYYYĬheck it out the Oracle TO_DATE() and PostgreSQL TO_DATE() functions for the details. The following shows the TO_DATE() function syntax: TO_DATE(string, format)įor example, to convert the string '' to a date value, you use the following statement: SELECT TO_DATE( '', 'DD MON YYYY' ) Oracle and PostgreSQL provide the TO_DATE() function that converts a string to date based on a specified format. Here is the result: Code language: SQL (Structured Query Language) ( sql ) Convert string to date using TO_DATE() function Similarly, the following example also converts the string 180101 to January 1st, 2018: SELECT CAST( '180101' AS DATE) SQL Server converts the string 2018 to January 1st, 2018: The following example shows how to convert a string to a date: SELECT CAST( '2018' AS DATE) In case the function fails to convert, it issues an error, depending on the implementation of a specific database system. The CAST() function returns a DATE value if it successfully converts the string to date. In this syntax, the string can be any DATE value that is convertible to a date. The following illustrates the syntax of the CAST() function: CAST (string AS DATE)Ĭode language: SQL (Structured Query Language) ( sql ) Ive tried using the following but it did not work: CONVERT(DATETIME, Sales.SalesDate, 103) AS DTSALESDATE, CONVERT(TIMESTAMP, Sales. ![]() Ask Question Asked 11 years, 5 months ago. SQL provides a CAST() function that allows you to convert a string to a date. MySQL convert date string to Unix timestamp. If you want to use the AM/PM notation, you will need to use. Convert string to date using CAST() function UNIXTIMESTAMP () function only takes a standard MySQL formatted date. 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 various functions that convert a string to a date in SQL. 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.
