For example, if a table in an Oracle database contains a field named "Field1" that is defined as char 3 , and you enter the value "a" into a row of that table, the following code does not return the row. This is because Oracle stores the column value as "a " padding "a", with trailing spaces, to the fixed field length of 3 , which Oracle does not treat as a match for the parameter value of "a" in the case of a LIKE comparison of fixed-length fields.
