### Is your feature request related to a problem or challenge? The place parses literal to `ScalarValue` doesn't care about the target data type. This may require somebody to cast the parsed `ScalarValue` to expected data type https://github.com/apache/arrow-datafusion/blob/c2b260620718f1f6e67fdb32af87c3b3551bc0f0/datafusion/sql/src/expr/value.rs#L30 ### Describe the solution you'd like Add a method to `ScalarValue` like: ```rust fn cast(&self, data_type: &DataType, force: bool) -> Option<ScalarValue>; ``` The third parameter `force` is a switch to whether perform force cast like cast integer to float or string to number. Without `force` this method only perform lossless cast (i.e., only cast to bigger type) ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
