Hi,
If you let a tabulation, you will have 0 for numbers.
supposing this is the file tab.txt :
a 1 c
a c
mysql load data infile c:/tab.txt into table tab fields terminated by \t
enclosed by \ lines terminated by \r\n;
Query OK, 2 rows affected, 1 warning (0.00 sec)
Records: 2 Deleted: 0 Skipped: 0 Warnings: 1
mysql select * from tab;
+--+--+--+
| a| b| c|
+--+--+--+
| a|1 | c|
| a|0 | c|
+--+--+--+
2 rows in set (0.00 sec)
IF you want to handle NULL values, you must change empty values to \N :
*** new tab.txt
a 1 c
a \N c
mysql load data infile c:/tab.txt into table tab fields terminated by \t
enclosed by \ lines terminated by \r\n;
Query OK, 2 rows affected (0.00 sec)
Records: 2 Deleted: 0 Skipped: 0 Warnings: 0
mysql select * from tab;
+--+--+--+
| a| b| c|
+--+--+--+
| a|1 | c|
| a| NULL | c|
+--+--+--+
2 rows in set (0.00 sec)

Selon Pete Lancashire [EMAIL PROTECTED]:
I've been surfing the list / google but can't find what to do
I have a tab sep file, where there are empty fields i.e.
tabtab
the fields are associated with a mysql table integer type.
how do I get the empty fields to become NULL instead of
0 (zero) with a warning ?
Thanks,
-pete
