Abstract: A set of processing core resources of a database system is operable to obtain the query statement regarding a set of data values of a dataset. The set is further operable to obtain source data type information regarding source data type of the set of data values and target data type information regarding target data type regarding resulting data of the query statement. When the source data type does not match the target data type, the set is operable to access a data type conversion path list to identify a set of entries. The set is operable to determine, for the set of entries, whether an entry of the set of entries includes a source data type that corresponds to the source data type information. When the entry includes the source data type, the set is operable to output a representation of data conversion path information of the entry.
