Combine Table?

[seeusoon]

Dear all,

I have below two tables. Table1 and Table2. After I loaded the data, Qlikview auto joined the tables using the key.

Table1

Key	Column1
SN1	A
SN2	B
SN3	C
SN4	D

Table2

Key	Column2
SN1	A1
SN2	B1
SN3
SN4	D1

Qlikview joined the table using the key.

Key	Column1	Column2
SN1	A	A1
SN2	B	B1
SN3	C
SN4	D	D1

Question here - If I want the null field in Column2 replaced with the value "C" in Column1. How can I replace the value and achieve below result?

	Column1	Column2
SN1	A	A1
SN2	B	B1
SN3	C	C
SN4	D	D1

Thank you.

tmp:
Directory;
LOAD Key, 
     Column1
FROM
Book1.xlsx
(ooxml, embedded labels, table is Sheet1);


Left Join (tmp)
LOAD Key, 
     Column2
FROM
Book1.xlsx
(ooxml, embedded labels, table is Sheet2);


NoConcatenate
tmp2:
LOAD Key
	,Column1
	,If(Len(Trim(Column2)) = 0, Column1, Column2) as Column2
Resident tmp;

DROP Table tmp;

And the results:

Pay attention that you will be left with only one table.
