Depends. If this is a correlation table and the combined columns are a
primary key,
SELECT ObjId,
COUNT(ElemId)
FROMElems
GROUP BY ElemId;
if the combination is not unique, then:
SELECT ObjId,
COUNT(DISTINCT ElemId)
FROMElems
GROUP BY ElemId;

Have you looked at cron on LINUX?

I have a question about MyODBC and the results of SQLGetTypeInfo from a
table with a column of type TEXT. The results show that the column is of
type VARCHAR with a length of 255. Is there a way to show the true
datatype? The MySQL that I'm running is 3.23.36.
SQL question..
So what is the best way to store information in a MySQL database through
MyODBC that is of a character type that is greater that 255 chars? BLOB?

If you only want it ascending, take out the DESC as in:
$query = SELECT * FROM gigs WHERE date '$today' ORDER BY date ASC LIMIT
3;

Well I was able to fix the problem by doing a Select into Outfile and
specifying in my select list and using IF...

Is there a way to tell MySQL to put a blank space instead of \N in the
tab-delimited files when it does a dump? I'm working on a MySQL to SQL
Server migration and having problems with the output files. I'm doing this
all in batch fellas so I'm not finding a good search and replace utility.
ok, more specific:
here is a table:
CREATE TABLE FOO (foo1 int NOT NULL, foo2 int NOT NULL Default 1)
If I do an insert into the FOO table with the following:
INSERT INTO FOO (foo1,foo2) VALUES (1,1)
Everything works as planned.
If I do an insert into the FOO table with the following:
Beings as I haven't gotten an answer to this, is there a better place to
find information on this?

Is there a way for me
Is there a way for me to NOT have a default value for a column in a table
that I define as NOT NULL?
EXAMPLE SQL:
mysql CREATE TABLE FOO (foo1 int NOT NULL);
Query OK, 0 rows affected (0.05 sec)
mysql DESCRIBE FOO;
+---+-+--+-+-+---+
| Field | Type| Null |
is there a max row length for MyISAM tables? I'm having a hard time finding
it.

Don't forget to ensure that the account that the mysqld is running under has
the proper permissions to the new directory. I ran into that one before..
