System Functions

GaussDB is compatible with most MySQL system functions, but there are some differences. If not listed, the function behavior is the native GaussDB behavior by default.

For most GaussDB system functions compatible with MySQL, the return value precision (the number of trailing zeros in the result) is inconsistent with that of MySQL. This is because the precision of some data types is lost in some scenarios and the precision cannot be correctly obtained. As a result, some functions are not fully adapted.
