Error parsing SQL statement
Cause
This error occurs when the SQL parser encounters invalid syntax in a SQL statement. The error indicates that the parser expected specific SQL keywords or operators (like "=", "+", "*", ">", "%", "&&", etc.) or SQL clauses (like "AND", "EXCEPT", "GROUP", "HAVING", "INTO", "LIMIT", "OFFSET", "OR", "ORDER", "UNION", "WINDOW") but instead found an unexpected character at the specified position (Line 5, Col:44 to Line 5, Col:45).
Common causes include:
Missing or misplaced SQL operators
Incomplete WHERE clauses or JOIN conditions
Missing commas between column names or values
Unclosed parentheses or quotes
Extra or missing semicolons
Invalid character encoding or hidden characters
Resolution
1. Review the SQL statement at the specified location: Check Line 5, around column 44-45 for syntax issues
2. Validate SQL syntax: Ensure all clauses are properly formed and complete
3. Check for missing operators: Verify that comparison operators (=, >, <, etc.) are present where needed
4. Verify parentheses and quotes: Ensure all opening parentheses and quotes have corresponding closing ones
5. Remove hidden characters: Copy the SQL to a plain text editor to identify any non-visible characters
6. Use a SQL formatter: Run the query through a SQL formatter to identify structural issues
7. Test incrementally: Comment out parts of the query to isolate the problematic section
8. Check for reserved keywords: Ensure column/table names don't conflict with SQL reserved words
