Here’s MySQL CONVERT syntax to convert character sets CONVERT(input_value USING character_set) Like MySQL CAST, you can cast data into BINARY, CHAR, DATE, DATETIME, TIME, DECIMAL, SIGNED, UNSIGNED data types.įor example, here’s how to convert literal value to another data type CONVERT(1, char)Īnd here’s how to convert a column (e.g id) to another data type CONVERT(id, char) In the above function, you need to provide input_value as literal string or column name, and data_type to which you want to convert this data. ![]() Here’s the syntax of MySQL CONVERT function CONVERT(input_value, data_type) Here are the steps to convert data in MySQL using MySQL CONVERT function. It can also be used to convert data from one character set to another. Here’s how to convert data from one data type to another using MySQL CONVERT function. In this tutorial, you have learned how to use the MySQL CAST() function to convert a value with any type into a value with a specified type.Sometimes you may need to convert data in MySQL or type cast data in MySQL. The following statement converts DOUBLE values into CHAR values and uses the results as the arguments of the CONCAT function: SELECT productName,įROM products Code language: SQL (Structured Query Language) ( sql ) Try It Out +-+-+ģ rows in set (0.03 sec) Code language: JavaScript ( javascript ) RequiredDate BETWEEN CAST( '' AS DATETIME)ĪND CAST( '' AS DATETIME) Code language: SQL (Structured Query Language) ( sql ) To ensure safety, you can use the CAST() function to explicitly convert a string into a TIMESTAMP value, as follows: SELECT 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. Summary: in this tutorial, you will learn how to use MySQL CAST function to convert a value of a type into another type.
