Netezza 将 csv 导入为空表

Question

I am importing a CSV file into Netezza using the INSERT INTO command:

INSERT INTO MY_TABLE
    SELECT
        *
    FROM EXTERNAL 'C:\\file.csv'
    USING (
        REMOTESOURCE 'ODBC'
        DELIMITER ','
        MAXERRORS 100000
        SKIPROWS 1
        ESCAPECHAR '\'
    )
;

Netezza "succesfully" finishes the task, ie no mistakes come up. However, the data is not imported at all. Out of 1000 rows, only 100 are imported and none of them contain anything.

I followed the code found in Netezza CSV load

I have also tried to import the data via the external table and it failed again in the same manner.

Am I missing something, for example some crucial parameter? This procedure has worked without problems before. I don't think there is anything wrong with the csv file I'm trying to import.

Answer 1

Based on the link you provided I see two parameters that may be required. Also a slight format change that may make a difference.

INSERT INTO MY_TABLE
SELECT * FROM 
EXTERNAL 'C:\\file.csv'
USING 
(
    DELIMITER ','
    MAXERRORS 100000
    SKIPROWS 1
    Y2BASE 2000
    ENCODING 'internal'
    REMOTESOURCE 'ODBC'
    ESCAPECHAR '\'
    QUOTEDVALUE 'DOUBLE'
)

IBM also has a Data Loading Guide that can be found here .

Answer 2

I finally found out the issue, it is explained in more detail in this thread:

loading files with dates into netezza

The problem was with importing Date formats. The following two lines needed to be specified in the code:

DATESTYLE 'DMY'

DATEDELIM '.'
