Why Is the Data Logged in Bad Records Different from the Original Input Data with Escape Characters?
Question
Why is the data logged in bad records different from the original input data with escaped characters?
Answer
An escape character is a backslash (\) followed by one or more characters. If the input records contain escape characters such as \t, \b, \n, \r, \f, \', \", \\ , java will process the escape character '\' and the following characters together to obtain the escaped meaning.
For example, if the CSV data type 2010\\10,test is inserted to String,int type, the value is treated as bad records, because test cannot be converted to int. The value logged in the bad records is 2010\10 because java processes \\ as \.
