Delete first row of csv file
I have a csv file, which is > 2 Gigs. I need to BCP that file to Sybase db , but I cant upload that b'caz first row of the file is failing. ( having some errors probably.) I can manually insert the first line into db & then I can upload the rest of the data in file, if i can delete the first row.
I have a wiered solution for this.I will ftp the file on unix, & want to delete only the first row.
then I willl ftp back the file to my local & again try to upload it on sybase db.
How do i delete the first row of csv file in Unix? ( no editor is able to open that file, other wise i wouldn't need to go for such starnge way ...)
Thanks in ad !

LEARN ABOUT PHP
sybase_result
SYBASE_RESULT(3) SYBASE_RESULT(3)
sybase_result - Get result data
SYNOPSIS
string sybase_result (resource $result, int $row, mixed $field)
DESCRIPTION
Returns the contents of the cell at the row and offset in the specified Sybase result set.
When working on large result sets, you should consider using one of the functions that fetch an entire row (specified below). As these
functions return the contents of multiple cells in one function call, they're MUCH quicker than sybase_result(). Also, note that specifying
a numeric offset for the field argument is much quicker than specifying a fieldname or tablename.fieldname argument.
Recommended high-performance alternatives: sybase_fetch_row(3), sybase_fetch_array(3) and sybase_fetch_object(3).
PARAMETERS
o $result
-
o $row
-
o $field
- The field argument can be the field's offset, or the field's name, or the field's table dot field's name (tablename.fieldname).
If the column name has been aliased ('select foo as bar from...'), use the alias instead of the column name.
RETURN VALUES
sybase_result(3) returns the contents of one cell from a Sybase result set.
