> In odb, user can write a map to determine an empty string should be treated
> as null or empty. However, this feature not work as expected.
> For example, I have a table, a map file and a data file as below(you can also
> refer to attached file):
> >>>table:
> create table testemp(id int, c1 char(20) not null, c2 char(20));
> >>>map:
> ID:1
> C1:2:emptyasempty
> C2:3
> >>>data
> 1,,abc
> 2,,def
> Then run odb cmd to load the data, the expected result is all data should be
> loaded, the atcual result is as below:
> odb.exe -d 14d4 -u trafodion -p traf123 -l
> src=testdata.txt:tgt=testemp:map=testmap.txt
> odb [2019-04-18 16:15:17]: starting ODBC connection(s)... 0

> [0] odb [Oloadbuff(10212)] - Error loading row 1 (State: 23000, Native 0)
> [TRAF][Trafodion ODBC Driver] General error. Null Value in a non nullable
> column. Row: 1 Column: 2
> the emptyasempty option does not work as expected:
