Known Causes

A parameter value does not conform to the expected data type or format (e.g., passing a non-numeric string to a function expecting an integer).
Missing or Extra Delimiters

Invalid Special Characters
The parameter value contains characters that are not allowed or are incorrectly escaped within the specific context of the SQL statement or function call.
