edit large CSV file before reading it to a table
조회 수: 10 (최근 30일)
I have a very large (16Gb) CSV file that contains one column with data separated by semicolumn.
I only need 2 columns from this data, but I cannot read it first since the memory is running out (I have 16Gb ram).
Is it possible to somehow separate the semicolumn to a column and read only the data I need (which is 2/6 columns)?
