ORA-01861: literal does not match format string

Question

When I try to execute this snippet:

cmd.CommandText = \"SELECT alarm_id,definition_description,element_id,
    TO_CHAR (alarm_datetime, \'YYYY-MM-DD HH24:MI:         


        

Answer 1

The error means that you tried to enter a literal with a format string, but the length of the format string was not the same length as the literal.

One of these formats is incorrect:

TO_CHAR(t.alarm_datetime, 'YYYY-MM-DD HH24:MI:SS')
TO_DATE(alarm_datetime, 'DD.MM.YYYY HH24:MI:SS')
