MySQL Error 2052: Missing Prepared Statement Metadata
Description
MySQL Error 2052 indicates that a prepared statement, intended for efficient and secure query execution, was used without its essential metadata. This metadata includes details about the statement's columns, parameters, and types. This error typically occurs when the prepared statement was not successfully prepared on the server or its metadata was lost.
Error Message

Known Causes
3 known causesIncomplete Statement Preparation
The prepared statement object was created on the client, but the actual preparation on the MySQL server failed or was not completed, resulting in no metadata being generated.
Statement Already Closed or Deallocated
The client attempted to execute a prepared statement that had already been explicitly or implicitly closed or deallocated, leading to the loss of its associated metadata.
Client-Server State Mismatch
A communication issue or an unexpected server reset caused the client's cached understanding of the prepared statement's state to differ from the server's actual state.
