new ( :NOOP, arg ) when TrueClass, FalseClass SQL :: BooleanExpression. Here, we will discussing all the different ways through which we can convert bytes to string: 1. new ( :NOOP, arg ) when String SQL :: StringExpression. The second string is prefixed with the ‘b,’ which says that it produces byte data type instead of the string data type. This operating will automatically convert any binary data type in the table into BASE64 String. The basic logic of this action based on: We select the value as table We convert the data in the table into JSON using the built-in hint 'FOR JSON AUTO'. new ( arg ) end when Numeric SQL :: NumericExpression. Option 1: Convert binary to Base64 using JSON.
