Awesome, yeah I have a space between the file size (700k) and filename (data_sample1_test) on purpose and hoped that each field was infact each string/delimited by spaces.
Also the reason I used BEGIN was because when I was playing with a Hello World script I came across on wikipedia I took out the BEGIN and somehow created an infinite loop where whenever I typed anything, it would be followed by Hello, World! until I forced a stop.

I understand what I did to create this infinite loop thing, as I just tried what you said and it happened again.
Was just a silly mistake on my part, and technically I suppose it's not an infinite loop at all, I'm just outputting the result straight to linux (i think)
So it was literally the difference between giving it a file to access from or not giving it a file
Accessing from data_SAMPLE1_test
Not accessing a file
I know that must seem extremely stupid and/or simple, but I guess I'm so new to this language it didn't occur to me straight away
Just written a great little script that analyses a flat ASCII CSV file and reports for any discrepancies with field counts per record etc.
Works fine on all the flat files except one, which has 113 fields per line. AWK can only seemingly cope with up to 99 fields.
Is there any way around... (2 Replies)

the $NF will get me the value in the last column, but if there is more than one word in the... (2 Replies)

DROP FOREIGN TABLE(7) PostgreSQL 9.2.7 Documentation DROP FOREIGN TABLE(7)NAME
DROP_FOREIGN_TABLE - remove a foreign table
SYNOPSIS
DROP FOREIGN TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DESCRIPTION
DROP FOREIGN TABLE removes a foreign table. Only the owner of a foreign table can remove it.
PARAMETERS
IF EXISTS
Do not throw an error if the foreign table does not exist. A notice is issued in this case.
name
The name (optionally schema-qualified) of the foreign table to drop.
CASCADE
Automatically drop objects that depend on the foreign table (such as views).
RESTRICT
Refuse to drop the foreign table if any objects depend on it. This is the default.
EXAMPLES
To destroy two foreign tables, films and distributors:
DROP FOREIGN TABLE films, distributors;
COMPATIBILITY
This command conforms to the ISO/IEC 9075-9 (SQL/MED), except that the standard only allows one foreign table to be dropped per command,
and apart from the IF EXISTS option, which is a PostgreSQL extension.
