Is there a simple MySQL command that will give a Row Count (# of records)

If it's a MyISAM table, just run a SELECT COUNT(*) FROM table_name.
It's really efficient. Try it. :-)

If your table is MyISAM, then
SELECT COUNT(*) FROM tablename
Will return a rowcount without a major performance hit as the rowcount
is stored and a table scan is not needed.

Here's a nice MySQL simple returning records query question!
I want to return a staement saying 'number of records shave been found'
for your
selection.
so presumably this is a simple row count based on the the returning
recordset?

Either with PHP or C you can use mysql_num_rows()

Hello all,
Does anybody have a SQL string to count the rows in two different
tables and
give you a total number of rows? I have been trying to find an
answer for a

Does it have to be in a single query. You could use a Union query and
then total the results in your program.
Select Count(Field1)
From Table1
Union Select Count(Field1)
From Table2;

if you count the (unqualified) join you'll end up with the product of
