Error Code Reference
The error code reference is a collection that provides unique identifier code to identify and distinguish various types of errors that may arise during DolphinDB server runtime operations and appear in system logs. It aims to assist users in interpreting error messages, identifying probable triggers or causes of the errors, and suggesting solutions or recommended actions to resolve issues indicated by the codes. This guide with a range of error codes covered help you diagnose and troubleshoot problems in DolphinDB.
