如何将 select 变体列与一个 csv 行作为雪花中的多个列？

Question

I got a table TABVAR in snowflake which has column Var_Col which is VARIANT type. I load there each row from some csv, so values are like 'val1;val2;val3'.

I know that i can query it as columns directly from csv, but i have to do it other way.

The question is how to query Var_Col to obtain something like:

select firstValFromVar_Col, secondValFromVar_Col, thirdValFromVar_Col
from  TABVAR

I mean the query like above and result be like:

Col1 Col2 Col3
val1 val2 val3

Output of Select * from TABVAR:

Var_Col
val1;val2;val3

Answer 1

It can be done with:

select   split_part("Var_Col", ';',  1)
, split_part("Var_Col", ';',  2)
, split_part("Var_Col", ';',  3)
from "TABVAR"
