Peter,

Here is a message I recently received from Bill Wemple
at Mapinfo about this exact topic.

 The limitation to the size of a table in MapInfo is
 2 billion rows and a
 4096 byte record length in each row.

Re: MI Importing a File

2000-08-30 Thread Kurt Ackermann

If your entire text file is set up the same way as your example, a quick 
and dirty solution could be to open the text file in Excel, a dialog box 
will open and you can set the column divisions and cell settings for the 
columns in there (I tried it with your example and it was very 
straightforward with no need to adjust the column width, only giving the 
cells character settings).

That makes a standard excel file which you can copy and paste into a 
Mapinfo browser after you create and give settings to a new TAB file. 
Ie, you set up a new empty TABle in Mapinfo with the three* (four if you 
want some kind of 'id' field) fields you require, then open the browser 
which will, of course, be empty; make sure it's active and paste your 
copied excel records directly into it.

I don't know Mapinfo's limit for records in one TABle offhand, but it 
would just entail creating enough TABles to handle your data if you're 
over the limit I assume.

*I'm not sure whether the example you gave was 3 or 4 fields (columns), 
but if it is 4 you could avoid the 3rd and 4th overlapping by doing a 
global replace, for example of 5 spaces with 10. Again, it's a very 
quick and dirty solution and anybody with even a smidgeon of Perl 
experience will laugh at it, but it works if you're only semi-computer 
literate, like me!

Re: MI Importing a File

Hi Kurt and Gregory

 I have a "txt" file with over 300,000 records (One Record per line) in

I do not think Excel can accept that many records.
We use Access to import huge TXT files instead of Excel.
Then it can be re-imported into MapInfo.

 If your entire text file is set up the same way as your example, a quick
 and dirty solution could be to open the text file in Excel, a dialog box
 will open and you can set the column divisions and cell settings for the
 columns in there (I tried it with your example and it was very
 straightforward with no need to adjust the column width, only giving the
 cells character settings).
