Hi
I face problem when I deal with " table row to variable loop start ".
I connect a table with two columns (Start_Date, End_Date) and
about 32 rows, which are supposed to have date values.
everything seems OK , but when I connect the " table row to variable loop start " output
to Data Reader to deal with Start_Date , End_Date I don't know why the values changes.
for example 2015-01-01 changes to 2013
and 2015-01-31 changes to 1983.
I would be really appreciated if someone could help me.

Hi,
can you post me a workflow showing the problem. I just tried it and it is working for me.

Which KNIME Version are you currently using? I use 3.4.0 and it is working as expected.
Actually, the thing I have tried to do is I would like to pass the values from Source Tables
and put them in loop to RUN my SQL script which deal with the values in Start_Date, End_Date in
WHERE part condition.

Hi,
I am not sure I understand your problem, for me this looks as expected.
Can you make me a screenshot of the flow variables?
Therefore, execute the Table row to variable loop start once, open its outport and this is what I would like to see.
I get the following information:
START_DATE" |
2015-01-01 |
END_DATE" |
2015-01-31
|
Where are you seeing the 2013? which variable is it?
Thanks a lot for making time.
actually , when I wanted to use variable in the loop(body)
as $${SSTART_DATE}$$,$${SEND_DATE}$$ the values are considered as number :
2015-01-01 = 2013 (dash mark considered as Minus!) .
everything seems OK before Loop body though!
but the interesting thing is I have put the Value between ' '(Quotation mark ) in the source table :
'2015-01-01' , then everything works well !
do you think is that related to my fault or the KNIME version or ...?

I think we are getting closer to the problem :-)
So you are using the value in an SQL statement and yes, this needs to be surrounded by Quotation Marks.
