------------------------------------
Hi Bryan,
No this while loop is not supposed to run more than once. Therefore it should
be if condition not a while loop. I will add the new patch with the tests.
All existing tests are clean.
This is the list of cases that I came up with. Do you have any suggesions to
include or exclude tests?
I think we should add these tests to ImportExportProcedureTest.java
For a table like this
A(petName varchar(50),3 varchar(50) , age int)
1.) pass cases
Columns by name and indexes
CALL SYSCS_UTIL.SYSCS_IMPORT_DATA(null, 'A', null ,'1,2,\"AGE\"', 'pet.dat',
null, null, null,0)
Columns by only names
CALL SYSCS_UTIL.SYSCS_IMPORT_DATA(null, 'A', null ,'\"PETNAME\",\"3\",\"AGE\"',
'pet.dat', null, null, null,0)
Columns by only names and changing the order of columns
CALL SYSCS_UTIL.SYSCS_IMPORT_DATA(null, 'A', null ,'\"AGE\",\"PETNAME\",\"3\"',
'pet.dat', null, null, null,0)
Only two columns out of four by name
CALL SYSCS_UTIL.SYSCS_IMPORT_DATA(null, 'A', null
,'\"PETNAME\",\"KINDOFANIMAL\"', 'pet.dat', null, null, null,0)
2.) Fail cases
not giving capital letters.
CALL SYSCS_UTIL.SYSCS_IMPORT_DATA(null, 'A', null ,'\"petname\",\"3\",\"AGE\"',
'pet.dat', null, null, null,0)
Give column name without '"' mark. Need to get the column named 3, but gets the
index 3 column.
CALL SYSCS_UTIL.SYSCS_IMPORT_DATA(null, 'A', null ,'3', 'pet.dat', null, null,
null,0)
Thanks

> To ease maintainability and legibility of client programs, it would be
> nice if callers of SYSCS_IMPORT_DATA_BULK (and possibly also
> SYSCS_IMPORT_DATA) could refer to columns in the COLUMNINDEXES
> argument by column *NAME*, as well as by index *NUMBER*.
> So, for example, a valid COLUMNINDEXES specification might be:
> '1,3,LastName,FirstName,7'
