问题
I am new to SAP HANA and was recently migrating some of our databases to it and found it very good in performance.
The problem I am facing is that I am unable to upload an array column in HANA. But I found there is a way to INSERT an ARRAY in HANA using the method
INSERT INTO T1 VALUES ( 1, ARRAY ( 1, 2, 3, 4 ) )
Since I have a .CSV file where the first two columns are integers and the third one is a bigint array from postgres and the it looks like:
input.csv
1,2,"{1545645,2652656,3545645}"
3,4,"{155535,244564654,346456456,448484,5456456465,664654564}"
9,12,"{14645646,24564564,3478484,447984894,5464646,644458648,745464,849494,9494848}"
How is it possible to upload an array column in HANA(SPS 12)? Any help is appreciated.

This has been discussed here on SO before. Using the ARRAY() function is the only way to insert an ARRAY into an array-typed column.
If you want to load array data from a file you will have to use a custom loading program that constructs the ARRAY(....) function call for each record.
Depending on your use case, you might reconsider using other storage options for your data.
