IMPORT with METHOD N

[Gregor =?UTF-8?B?S292YcSN?=]

Hi!

Let's say I have a table TABLE 1:
CREATE TABLE TABLE1
(
TAB1_ID BIGINT,
TAB1_NAME VARCHAR(100)
)

which has 10 columns in and from which I do an EXPORT like:
EXPORT TO TABLE1.IXF OF IXF SELECT * FROM TABLE1

Then I have a table TABLE2:
CREATE TABLE TABLE2
(
TAB2_NAME VARCHAR(100)
)

into which I'd like to import TABLE1.IXF, but only TAB1_NAME:
IMPORT FROM TABLE1.IXF OF IXF METHOD N(TAB1_ID, TAB1_NAME) INSERT INTO
TABLE2(TAB2_NAM E)

This commands does import all 10 rows, but the values are NULL and there are
no warnings or errors.
Is this supposed to work like this ?

Best regards,
Kovi

I'm a bit surprised that works at all given that you've specified two
columns in the source and one in the destination. I'd expect something
like this instead:

IMPORT FROM TABLE1.IXF OF IXF
METHOD N (TAB1_NAME)
INSERT INTO TABLE2 (TAB2_NAME)

In other words, the columns you specify as the argument to METHOD N map
to the columns you specify after the action parameter (INSERT /
INSERT_UPDATE / REPLACE / CREATE), hence the command above is simply
ignoring the TAB1_ID column in the source file.


Cheers,
