The main purpose of this work is to fix some known issues in scalar functions. First, the support for timestamp data type in mathematical scalar functions has been removed, considering that the data type of timestamp does not have practical significance in the use of scalar functions. This part has made modifications to all mathematical scalar functions and also to the related IT. Secondly, support for the || symbol has been added, as the || symbol is semantically consistent with the concat function, so in astbuilder, || is treated as a function call for concat. Finally, for the return value types of upper, lower, and trim, they have been modified to return string instand of consistently with the input type, which is a modification made according to the actual application requirements. -- This is an automated message from the Apache Git Service.
