ORA-01861 literal does not match format string
Cause: Literals in the input must be the same length as literals in the format
string (with the exception of leading white space). If the "FX" modifier has been
toggled on, the literal must match exactly, with no extra white space.
Action: Correct the format string to match the literal.
