Native SQL didn't return the correct data

[Former Member]

Hi all,

I have got an issue when using native SQL.

I want to do case-insensitive fetching, so I am using native SQL.

In DB table, the data is like:

col1 col2

001

002

col1 is key and col2 has intial value.

In coding:

lv_abc = 'ABC'.

select col1 from table into :gs_xxx where (upper)col2 = :lv_abc.

Normally, you should have got no data.

But the odd thing is, I did get these 2 entries.

I have tried open SQL as well and I get nothing which is correct.

So I am wondering why native SQL would return the wrong data set.

I suppose those are not "initial" values (space, zeroes) but "null" values, so fulfill any check, try to add a criteria IS NOT NULL.

col2 is initial value. I have also tried SE11, and enter 'ABC' as search criteria and get nothing.

So why the data can be fetched if the where clause is col2 = 'ABC' in native SQL.

It's really strange.
