What is the statement that varbinary type is converted into numeric type and string type in MySQL?

Javascript comes with parseInt(str) function.

Parameters:

Str, a string containing numbers.

Return value:

If the first few characters in str are numbers, the number is returned.

If the first character of str is not a number, NaN is returned.

For example:

parse int(" 1234 ")； //Return 1234

parse int(" 1234 a ")； //Return 1234

parse int(" 1234 a5 ")； //Return 1234

parse int(" a 1234 ")； //return NaN

parse int(" ABCD ")； //return NaN
