Select Count Syntax


im just a begginer in mysql. I have a problem on how can i place a result of a select statement query in a variable.
Here my select statement:
Select count(employee) from employee where empmonth =
1 and empyear = 2005;
This syntax is ok, it return a result of 123894 records. But what I want is to place the result in one variable that i can access inside the program so that i will run this select statement only once. I have tried this one syntax:
Select count(employee) into ll_count from employee
where empmonth = 1 and empyear = 2005;
but it return a result of zero record.

SELECT COUNT Syntax Error
Have a syntax error with the following query ...
SELECT number COUNT(*) AS vessels FROM process_fleet WHERE uid=1
No idea what is wrong with the sytax... can only one see what I'm missing?
Count(*) In A Select Returns "1". It Should Behave Like Select Count(*)
i'm trying to make a query work properly but I got lost:

SELECT *,count(*)
FROM cancons c, musics m, discos d, r_discos_cancons rdc
WHERE c.c_id_music = m.m_id
AND rdc.rdc_id_disc = d.d_id
AND d.d_id_music = m.m_id
AND m.m_id = 24
GROUP BY c_id

note:
cancons (ca) = songs (en)
discos (ca) = cd's (en)
music (ca) = musician (en)

don't worry for the WHERE part. i need it because of the foreign keys.
this query returns a table with the title of the song and some more data. on the right side, I get another column called "count(c_id)" with the number "1" in it for each row. That's supposed to be due to the "group by" clause, I think.

I'd like to get the table with the songs, as usual, and, with the same query, I'd like to get the total number of rows selected.
SELECT COUNT(*) Or SELECT .. LIMIT 1?
If the purpose of a query is to see if atleast 1 record exists which would be faster?

SELECT COUNT(*) or SELECT .. LIMIT 1?

Both would use a WHERE clause.
SELECT Syntax
I am trying to check a variable against a specific column in my database. I know that i have sucessfully connected to the database and chosen the correct table, and as far as I can see, the syntax for this code is correct:

$usernamesQuery="SELECT 'username' FROM 'login' WHERE 'username' = '".$username."';";
$currentUsernames=mysql_query($usernamesQuery) or die ('ERROR 7: unable to connect to database: '.mysql_error());
if($username==$currentUsernames) {
echo "<script language='javascript'>alert('ERROR 8: Please choose another username')</script>";
exit();

However the when trying to carry out the script, the server returns: "ERROR 7: unable to connect to database: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near ''login' WHERE 'username' = 'yonni'' at line 1"
SUM In SELECT Syntax

I've a table with a column that its name is number.
in this column I've some numbers that some of them are repeated.
How can I select all numbers with no repeat.
I wana select all numbers but if a number repeated I don't wana have it twice or more.
CASE WHEN In SELECT Syntax
I have a table (2 columns):

Col1(string), Col2(decimal)
ABC1,10
ABC2,20
ABC3,50
ABC1,5
ABC4,10
XYZ2,5

I want to get result to sum all ABC* and subtract all XYZ*. Example (ABC*-XYZ*) and get result 80. So:(10+20+50+5+10)-(5+10)
SELECT Syntax With EXISTS NOT()
2 tables are concerned: user_games and games_details. i want all games in my result which do not yet exist for the specific user (respectively have no games_id in the user_games table) games_details.id is autoincrement and user_games.games_id is set to this correctly.

But i still get no result and no error with the following code:

$sql = "SELECT id, name

WHERE NOT EXISTS(
SELECTgames_id

How To Select Count(*) And Something Else?
How do you select a count and another field without having to do two queries?

here's the query I'm using:-

SELECT
count(*) as totals, user

FROM user_posts
WHERE post='$md5'
SELECT COUNT
I'm counting rows from a mysql database able and trying to display the count. I have the following.

$count = "SELECT COUNT(*) AS newcount FROM stores";
$cr = mysql_query($count);
if (!$cr)
die(mysql_error());
if($cr){
//Make site ID now ...
$var1 = $newcount;
$var2 = P00;
$var3 = $var2.$var1;
}

The problem I have is thet $newcount seems to be empty. I have used count and not put "AS newcount" in the query but that made no difference. I have tried to echo the $newcount but again it is empty. Now, in PHP is there something else I must do to return the value of $newcount that I have missed?
SELECT Count
how to use SELECT Count.
Select *, Count
I want to perform a select query, but it doesnt return the data i have in mind. The result should be all info in 1 row with the highest date plus a total of game_id
This is what works best sofar.

SELECT * , COUNT( game_id )
FROM `battle`
WHERE game_id =4
GROUP BY game_id
ORDER BY b_date DESC
LIMIT 1

Yet this doesnt return the last date but the first. Everything else i tried the count function returned 1 even though it should be 20 for example.
How can i solve this?
SELECT COUNT(*)
I heard SELECT COUNT(*) can take a lot of resources if your counting a table with lots and lots of rows (hundred thousands, millions).
What if you add A WHERE clause to it? So something like:
SELECT COUNT(*) FROM table WHERE pid = ?
(pid is a index too btw)
IF adding a where clause, does it still scan the entire million plus rows, or only scans what is returned from the WHERE clause?


SELECT COUNT Or SUM()
Is there a difference between these two functions when your trying to gather how much a item appears in a database?
For example, which one will be better for a database w/ ~150,000 rows.

SELECT COUNT(category_id) FROM Threads WHERE category_id = '2'

Will return ~50,000 rows matching category 2

OR

SELECT SUM(category_id = '2') AS total FROM Threads
total will be ~50,000 rows also.
Select Count
I need to do the follow SQL..PHP Code:

 SELECT COUNT(t.id), COUNT(p.id) FROM threads t, posts p 

and add the two counts together... within the SQL query can i do this?
or do i just have to return the arrays and added the results seperatly.
Syntax Error With Nested SELECT
Working with MySQL 4.0.27-standard via phpMyAdmin (and Perl)

I've been getting error #1064 for certain SQL statments, and have traced the problem down to nested SELECTs.

This works fine:

SELECT `CITY` FROM `pa_geotags` WHERE `PLACE_ID` = 1303 ;

Whereas this (just a trivial example to show the point):

SELECT `CITY` FROM `pa_geotags` WHERE `PLACE_ID` = (SELECT 1303) ;

gives rise to:

#1064 - You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT 1303 ) LIMIT 0, 30' at line 1

I've tried several other (more complex) nested SELECTs, all give exactly the same type of error. phpMyAdmin seems to be non-optionally adding 'LIMIT 0, 30' to the end of my SQL before submitting it, but I don't think that's the problem; I sent the same SQL to the same database via a PERL script and also got a syntax error reported.
Select Syntax Using Variables / Functions
I'm in the process of converting various stored procs in SQLServer over to MySQL. In doing this, I ran into the following problem:

(using the getdate() and CURRENT_TIMESTAMP functions for illustration purposes)

In SQLServer, I can do the following:

select getdate() where getdate() <> getdate()

In MySQL, the following statement is not valid. why?

SELECT CURRENT_TIMESTAMP WHERE CURRENT_TIMESTAMP <> CURRENT_TIMESTAMP;
Multi Table SELECT Syntax.
Here's what I'm trying to do without all the extra columns for the project. I have 2 tables. A user table with columns (int) id, (varchar) username and a another table called related with columns (int) user1, (int) user2 which are id values from the user table.

I need a select query which returns rows with the id and username for both people. I know i could store the username in both tables and make it easy but that cant be a good practice.
Syntax For Using Variables In A Select Statement
I haven't figured out how to use the Query Browser yet and all docs I've found so far only talk about stored procedures so I'm at a loss.

I'm running MySQL 5.0 using DRIVER={MySQL ODBC 3.51 Driver} in my vb application.

I have 2 tables, Users and Transactions.

In the Users I have a User Pin Number and in Transactions I have a Transcation Pin Number.

I do this...
rsUsr.Open "SELECT * FROM users", conn, adOpenDynamic, adLockOptimistic ... ok.

Then I want to do this...

strUPN = rsUsr("usr_pin") ... ok

rsTran.Open "SELECT * FROM transactions WHERE trans_pin = strUPN, conn, adOpenDynamic, adLockOptimistic" ... not ok

How do I get the variable strUPN into the SELECT statement.
Syntax Error In Select Statement
I use MySQL 4.0.18 in Linux environment, and I'm new to MySQL. I can get the returned records if I run the following SQL statement in Oracle. But I got syntax error when I run the following SQL statement in MySQL. Can someone tell me what the wrong is with the following SQL statement? Thanks a lot!

select hostname, vendor from serverinfo where vendor IN (select v_name from vendor);.
Select Count Where Entries Are < 4
I want to count how many users have 4 or less entries in the table, so, so far i have
SQL
SELECT COUNT (*) AS fourLOCS FROM
(SELECT DISTINCT locsLog.locStudentID FROM locsLog)
which counts all the entries in the locsLog table and groups them by studentID so tells me how many users have made entries.
How do I limit this so it only gives me a total number of users who have made 4 or less entries. I think I'd need WHERE after the nested SELECT statement, but I don't know what I'd put in it. I tried
SQL
SELECT COUNT (*) AS fourLOCS FROM
(SELECT DISTINCT locsLog.locStudentID FROM locsLog)
WHERE fourLOCS <= 4
but had an error message (I'm doing it with an Access database with ASP and the message was 'Too few parameters. Expected 1').
Select Count(*) Timing Out
I'm doing a "select count(*) from table1" and it takes forever, more then 3 minutes, for the result to come back. I'm running MySQL 5.0.19 on RedHat, I know my table has 51M records. When I run a "show table status where name='table1';" it returns the results in a few ms and gives me a record count. My table is defined below, I've tried forcing use of each index individually and forcing no indexes and all combinations and always the same result. Server is an intel based 64bit cpu with 16GB ram with pretty much nothing else going on......
Select Count(*) Issue
I have what I think is a simple SQL command getting unexpected results.

PHP code:

$query = "select count(*) as total_rows from part_master where mfg_id = '933' and part_no = '3601' order by part_no";

$result = mysql_query($query);

The result is total_rows = 0.

I run the same SQL from the DOS command window and get:

mysql> select count(*) as total_rows from part_master where mfg_id >= '933' and
part_no = '3601' order by part_no;
+------------+
| total_rows |
+------------+
| 1 |
+------------+
1 row in set (0.01 sec)

I'm running the latest versions of Apache, MySQL and PHP on a WinXP box.

Php, Mysql And Select Count
I use as the base an existing system, called PHPNuke. My programming work before are only on Assembler, C, C++, Perl and other Databases than MySQL. In PHPNuke and/or the MySQL Queries contained in it there are sequences for simple counting rows (without further processing). The following sequence is permanently used (as example):

$result = $db->sql_query("select * from "$prefix."_sometable where someting='$foo'");
$numrows = $db->sql_numrows($result);

I would make it rather in such a way:

$result = $db->sql_query("select count(*) as count1 from "$prefix."_sometable where someting='$foo'");
$numrows = intval($db->sql_fetchrow($result['count1']));

Now my hopefully not too stupid question. Is there a reason, why e.g. in MySQL large genuine result quantities must be formed, only in order number of lines to determine? I worked so far actually only with other databases. But it is quite possible that that makes any sense here - who knows? Knows here someone the mystery solution?
SQL - Select Where Count Equals Zero
I have a table of products and a table of ratings so people can rate the products. I would like to select all the products the user has not rated. My thoughts are to join and count returning rows where count equals zero. But I am just not sure how to do it.

I have this that does the exact opposite of what I need, this returns just the row that I rated, I need all but the rows I rated, Make sense?

SELECT products.*, COUNT(ratings.id) AS count FROM products
LEFT JOIN ratings ON ratings.rateable_id=products.id
WHERE ratings.user_id = 10
GROUP BY products.id

(10 is the hard coded user id)

How can return ALL except the rows I rated?
Select Count(*) > @foobar
i have a query as follows and is unsure whether it is mysql or php:

$result = mysqli_query("SELECT COUNT(*) > @foobar AS status ....") where
it's suppose to get a one row value of either '0' or '1' (false or true)

if i were to do a SELECT COUNT(*) FROM...
i can use the php $row["COUNT(*)"] to refer to the index.

if i were to do a SELECT COUNT(*) AS status FROM...
i can use the php $row["status"] to refer to the index.

but in this case SELECT count > @foobar AS status,
refering to $row["status"] gives a empty value. however, running the
same query in mysql command prompt produces

+------+
|status|
+------+
| 1 |
+------+

php doesn't support such select statement? even array_keys($row) returns
empty.
Select COUNT(Name) Into PCount

Select COUNT(Name) into pcount from agent where Name = 'goh';

it return me the correct result....

may i know what is the problem and how can i solve it ??

Select Statement With Count
I want to know how many different etries there are in one column. My table: pics{id, pic_name,category} There are many pics inside, but only a few different categories, e.g. (outside, inside, garden). Now I need a Select count on this column, and for the example above the result shoud be "3" - 3 different categories

"SELECT DISTINCT COUNT(category) FROM pics"
delivers a much higher number, it counts all rows of the table.

Slow Select Count(*)
I have a table with 75,000 rows.

An Explain tablename shows this

'TourPartsID', 'int(10) unsigned', 'NO', 'PRI', '', 'auto_increment'
'TourPartID', 'int(10) unsigned', 'NO', 'MUL', '', ''
'TourPartTypeID', 'int(10) unsigned', 'NO', 'MUL', '0', ''
'Language', 'int(10) unsigned', 'NO', '', '0', ''
'XML', 'mediumblob', 'NO', '', '', ''

When I do a Select count(*) from table, it takes about 12secs to return my number. This is occuring in the QueryBrowser and from the .NET library when it calls the Stored Procedure that does the Select count(*)....

My only quess that is my last column is a MEDBLOB but since I am NOT indexing that, I would figure MySQL ignores it.

Question About Select Count(*) With Group By
suppose a hypothetical table called 'table' with one field called 'field' of
an arbitrary type.

select count(*) from table where field='value' group by field

produces no rows when run under the latest mysql. without "group by" it
produces 1 row.

is this according to the SQL standard or is this just a coincidence? in
other words, can i rely on this behaviour to deduce that there are no fields
with value 'value' in 'table'?

Non-Numeric Result From SELECT COUNT(*)
I'm using MySQL 4.1.11 and MyODBC 3.51.11.
I've a problem with SELECT COUNT(*) query.

I'm using mysql in ASP. I'm executing this query for example:

Select Count(*) as TotalMembers From Members; //with recordset("Totalmembers")
-- or --
Select Count(*) From Members; // with recordset(0)

but both of these queries aren't giving Numeric (Integer) results...
I'm cotrolling them with IsNumeric function by ASP. But it gives False result.

Also i cannot using mathematical operators such like +-*/ . Because result isn't numeric. And an error occurs.

If you know asp, could you try to use math operators with select count(*) result?

Select Count From Multiple Tables
I want to select persons from a person table, and count from an "events", "trainings", and "leads" table, but I'm not able to figure out how to select distinct so that I get one person each and a count for how many times that person appears in each other table.

Is it even possible to do what I want?
