Reading specific rows from a large sas7bdat file #317
Description
Activity
Is there a way to add functionality to read specific rows from a large
sas7bdatfile? The issue I'm facing is that I have large SAS files (around 10GB) along with text files (an exact, flat copy of the SAS file). Based on the text file, I can specify the subset of rows that I'm interested in (around 10% of the file).@BERENZ Are
readstat_error_t readstat_set_row_offset(readstat_parser_t *parser, long row_offset)andreadstat_error_t readstat_set_row_limit(readstat_parser_t *parser, long row_limit)an option here?Another option is to specify a filter while reading, for example, reading rows based on a column. However, I understand that this may be more challenging to implement.
I do not see how to implement this using the current version of ReadStat.
