Hopefully, now you can easily convert data in MySQL. mysql> select convert('wewewwbwbddwg',char) Here’s a sample to convert small blob into char. MySQL CONVERT does not support conversion to text data type. You can also use it to convert timestamp to date. Please note you can only cast to UNSIGNED or SIGNED integer data types. Here’s an example to MySQL convert string to signed integer. mysql> select convert('2.134',decimal(4,3)) īonus Read : How to Disable Foreign Key Check in MySQL SIGNED, Converts value to SIGNED type, which is a signed 64-bit integer. You will need to convert string to decimal. CHAR, Converts value to CHAR type, which is a fixed length string. mysql> select convert('2.134',decimal(4,3)) Īgain, MySQL does not support conversion to floating point data type. You will need to convert string to decimal. MySQL does not support conversion to double data type. Here’s how to convert string to decimal mysql> select convert('1.234',decimal(4,3)) Here’s how to convert string to date mysql> select convert('',date) As such, they often need to be converted into a more appropriate data type, such as a number, date, or what-have-you. Let us look at some examples of MySQL CONVERT function. | convert('test string' using 'latin1') | Here’s an example of how to cast as latin1 mysql> select convert('test string' using 'latin1') In the above function, you need to provide input_value as literal string or column name, and character_set to which you want to convert this data. 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. Here are some examples of DECIMAL.Sometimes you may need to convert data in MySQL or type cast data in MySQL. The square bracket describes- everything inside the brackets is optional. The basic syntax for it is: CONVERT(exp, DECIMAL)]) Code language: SQL (Structured Query Language) ( sql ) As the name suggests, DECIMAL produces a decimal value and has two optional parameters M and D, where M is the maximum number of digits, also known as precision, and D is a number of digits after decimal point known as scale. You can check MySQL official documentation for the implementation of every data type. We will see a few data types conversion here, which will help you understand the usage of the CONVERT() function. You can convert the data into one of the following data types: DATE, DATETIME, TIME, DECIMAL, CHAR, BINARY, DOUBLE, FLOAT, SIGNED, UNSIGNED, YEAR. Though the CONVERT() function allows you to convert the value into a specified data type, the number of data types is limited to convert the value into. Let’s see the syntax of the CONVERT() function with some examples. Note that you don’t need to use the MySQL CONVERT() function all the time to change the data type of values because generally, implicit conversion takes place for converting lower data types into higher data types. That’s where MySQL CONVERT() function comes into action! But, you should not always rely on implicit conversion of the data because, in some cases, you might face errors and will end up inserting false/wrong values. Have you ever tried inserting an int type data into the char type column in MySQL? If yes, you might have realized that MySQL implicitly converts the data type of value before inserting it into the database. In such a case, you can use CONVERT() function to get your work done! It’s that simple! Let’s suppose you have a float value in your program, which is generated somehow, and you want to store it in the database as an integer after rounding it. As the name suggests, MySQL CONVERT() function converts the value from one data type to another.
