How to convert double to varchar in MySQL?

In MySQL, you can use the CAST function to convert a value of type DOUBLE to type VARCHAR. Here is an example:

SELECT CAST(your_double_column AS VARCHAR(10)) FROM your_table;

In the example above, your_double_column is the name of the DOUBLE type column you want to convert, and your_table is the name of the table you want to query. VARCHAR(10) specifies that the converted VARCHAR type has a length of 10. You can adjust this length according to your needs.

Please note that using the CAST function for type conversion may lead to data truncation or rounding. Ensure that the converted data type can accommodate your data and does not lose precision.
