Hello.
Usually only benchmarks will show a real picture
for you. Create foreign keys, perform some tests. Then
temporary disable FKs using SET FOREIGN_KEY_CHECKS=0 and
repeat the performance measurement. Super Smack is a good
tool for such kind of analysis. See:

hi ,
I am using the Load Infile utility to load data from file to MySQL DB.
When trying to load different amounts of data, I observed a notable
difference in the time taken by that.
Test 1
Amount of data - 5.5 million rows. Time Taken - 6+hrs Approximately.
Test2
Amount of data - 0.45
Are there indexes on the table? Could be that.

Yes, there are indexes on the table. Do you mean to say index is the
culprit.

Subject: Re: Major Difference in response times when using Load
Indexing can play a big role in the load time differential. When
loading .45 million rows, MySQL may be able to handle the sorting for
indexes in memory. With 5.5 million, it's more likely to have to go
to a temp file. You then could end up thrashing you disk, causing big
slow downs. If

OK, you confused me. How can 16 be bigger than 16? For character-based
fields, the number in the parentheses shows the length of the field,
does it not? The first part, the text or char or varchar or ...,
tells the engine what kind of data a field will contain.
How can TEXT(16) hold more
I can get this to work just fine:
?php
$number = 23999.39;
print $;
print number_format($number, 2);
?
Comes out $23,999.39
I'd like use the number_format() thingie on an array returned from a
mysql_query.
My current program snippet looks like:
$res =
I believe the (16) is the size of offset pointer used to locate the text
data elsewhere on the disk. They are all (16 bits)...Sybase does this as
well and is an odd (ok it's stupid) notation. This is one of those
things you need to adjust by hand when convert from one db to another.

Sometimes, after an upgrade it is necessary to rebuild indexes
in the tables (I'm not sure if it always produces an error if
you haven't done it). In general - usual recommendations for
