MySQL Error 1342: Incomplete Comment Block Parsing
Description
MySQL Error 1342 occurs when the parser encounters the end of a file or input string while it is still expecting the closing characters for a multi-line comment block. This typically indicates that an SQL comment, specifically one started with `/*`, was not properly terminated with `*/` or the script was truncated.
Error Message
Unexpected end of file while parsing comment '%s'
Known Causes
3 known causesUnterminated Multi-Line Comment
An SQL statement contains a multi-line comment that was started with `/*` but was never properly closed with `*/`.

Malformed Comment Syntax
While less common, an incorrectly structured comment (e.g., nesting comments improperly) might confuse the parser and lead to an 'unexpected end of file' error.
