MYSQL :: Select / Count Not Showing Records ... Permissions?

Select Count(*) Showing -1 Rows.
In one of my preliminary tests with mysql, the below statement is showing the following way. What does -1 rows signify in the table with the select count(*) query. Is this (-1 rows in the query result) an error condition to be taken care ?.

Slow Select Using Count(distinct) In A Table Bigger Than 100000 Records
Recently I started using MYSQL in my enterprise. I made a table which has around 100000 records. The problems is that it is really slow.. Im trying to do a query in which I get the number of distinct users per day.

This is my query:

select date(startedDate) as mydate, count(distinct(Users)) as users from Mytable
group by mydate

It is really simple and it does it correctly but it takes one minute.. One minute is not too much time but i need to insert around 10 000 000 records and thats what worries me.....

Showing All The Records With The Same Name
I was wondering how to write an sql that'll say

"show me all the records that have the same name"

I have about 500 records, and i would like to know which of them have the same name (which is a column in my table).

IN Query Showing All Records If Used With Same Field Twice
I have 2 tables programs and programType. programs has 5 records and programType has no records. When I run a query like "SELECT * FROM programs where id in (select programid from programType) and id in (select programid from programType)" I get all records But When I try to run "SELECT * FROM programs where id in (select programid from programType)" Then I get no records.

DISTINCT Still Showing Duplicate Records
Why won't distinct work? The sql IS selecting correctly but its showling records with the same f.preplyid

CODE

SELECT DISTINCT (f.preplyid), f.pid, f.ptid, f.ptid2, f.puid, f.psubject, f.ptype, f.ptime, t1.tid, t1.tname tname1, t2.tid, t2.tname tname2 FROM forumpost as f, thread as t1, thread as t2 WHERE t1.tid = f.ptid AND t2.tid = f.ptid2 AND f.puid =2 AND f.ptype=1 AND f.puid NOT IN (SELECT fp.puid FROM forumpost as fp WHERE fp.ptype=0 AND fp.pid=f.preplyid) ORDER by f.ptime desc LIMIT 7

Only Showing Records That Do Not Exist In Another Table
How do I show a listing of all records within one table that do not exist within a second table?

For example:

Table A
----------
apple
orange
pineapple
banana

Table B
----------
orange
cherry
lime
banana

I want all records in A that do not exist within B to show. thus I should have the results of:

apple
pineapple

What would my sql statement be if my column name was "fruit"?

Count Related Records, But Show Records With NO Related Records Also
cl_items
========
it_id (pk)
it_ownerid
it_name

cl_offers
========
off_id (pk)
off_itid (fk) -> to it_id
off_whoid

My query needs to output ALL of the records in cl_items AND still show how many offers are on each item (from cl_offers)

I can't get what I want through the GROUP BY because I want to show the records in cl_items which DO NOT have any offers on them yet also.

Is there any way to do this with mysql only?

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.

Count Records Per Day And Show Max
I've been using basic sql for a while and always used PHP to get round
complicated queries but now I need to see if I can create a query that
will show me the busiest day in our helpdesk and return the date and
the number of calls.

We have a database with a table called tracking which has date fields.
I want to count all teh records for each day, and return date with the
highest count and the count itself...

I'm sure its possible but I'm stuck as to what to google for...

Count Records Within Query
I have the following information in table 'Test1':

field1  field 2
000001  000000
000002  000001
000003  000000
000004  000000

I want to write a query that will only display the unique field 2 records and as well provide a count of how many records have that id.

output should look like

field2  recno
000000    3
000001    1

can some one help with the trick to make this work?

Count Records In 2nd Table
Create a result set with all records from table A and counted related records in table ....

Count Records From Two Tables
I have two tables and I want to count the number of records where field1 = 1.

tbl1    field1
           1
           2
           1
           0

tbl2    field1
           0
           0
           1

Result should be 3

Can someone help with the right coding?

How Do I Do A Count Of How Many Records Are Tagged Under One Tag?
How do i do a count of how many records are tagged under one tag?

SELECT DISTINCT ut.uxtagid, ut.uuserid, ut.uprivate, tt.tid, tt.ttag, tt.trated FROM usertags ut, thetags tt WHERE ut.uuserid=1 AND ut.uxtagid=tt.tid ORDER by tt.ttag

"thetags" contains the actual tag name like this:

tid, ttag

"usertags" when a user tags a record its stored here, and the records here are linked to the tag name

uuserid = the user who tagged it
uxtagid = is joining the "thetag" table to identify the name of the tag
uxforumpostid = the record that is being tagged

Count And Arranging Records
I need counting the number of records each user has and arranging their outputs.

This is my sample table:
uname | uid
-------------
"bob""1"
"bob""1"
"bob""1"
"james""7"
"james""7"
"lars""11"

I'm trying to select the uname and uid from this table based on which users have the most records in there.

So in this case the output would be

"bob""1" "3"
"james""7" "2"
"lars""11" "1"

Bob will be top since he has 3, james will be next and so on. The 3 2 1 you see is the number of records each has.

Count Deleted Records
Is there a way I can count/display the number of records affected by a delete statement on my webpage.
I currently have a delete statement:
DELETE FROM applications WHERE Date < whenever

can I combine this with a COUNT ??

Get List (count) Of Records
I want to get a list of records with duplicate (or triplicate, etc.) fields.
I tried:

SELECT *, count(*) as q FROM test WHERE q > 1 GROUP BY field1;

This didn't work because "q" is regarded as a missing column. Is there a
way to do this in a single SQL statement?

Compare Count Records
I need some help with some SQL I need to write.
Here is what I'm trying to do:
I have 2 tables in the same format. Table B is a subset of Table A.
For each key value I need to count how many records I have in table A and in table B and output the entries that are missing from table B.

E.g. for key 100 table A has 5 records and table B has only 2.
I need to output the missing 3 records.

Get Count Of Matching Records
I have two tables, that I am trying to match up rows and count the number of times first_name AND last_name in table A match first_name AND last_name in table B. What is the best way to do this without creating a mess of queries and code?

Getting A Count Of Records Based On Inner Relationships
I am making a PHP-MySQL forum. I have a table "forum" that holds all the posts.

Fields in forum: ID, user, title, body, threadID, datePosted.

All top level posts (ie, original posts for a thread) have a threadID=0. All other posts are comments, hence their threadID is set equal to the 'ID' of the original thread post.

I can get a list of the last 10 top level thread posts:
select * from forum where threadID=0 order by ID desc limit 0,10;

Also, I can get the # of comments for an individual thread (for instance, thread # 37):
select count(*) as Expr1 from forum where threadID=37;

How in the heck do I form those two statements into one statement? In my main forum view where I list the last 10 threads, I want returned in each result set the ID, title, user, and the # of comments posted in that thread.

Sql Query For Count Records Of Current Week
I have a registration form that saves the registration date on a datetime column. I would like make a query to know how many records are in the table that where for the current week. For example, I'm on week 25 and I want to know how many records I have for this week without the need of specifying the from and to dates. Is there a way to do this?

Join Tables To Count Number Of Records?
I've two tables:

responses
==========
response_id
schema_id
timestamp

answers
==========
answer_id
response_id
answer

(that's a cut down version, but will do for this question)

I need to get all the responses where there is at least one answer in the answers table. But I do not want the answer data. It's literally a quick check for an export to say "get me all the responses where there's at least one question answered". I have this: Code:

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.

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.

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.

What is this type?

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
i wanna count the total number of records by using this sql query...
Select COUNT(Name) into pcount from agent where agentcode = 'abc123';

this return me the total number of all records...

but when use this query:

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 Count Problem
I have two queries that I want to combine.

select Count(flag) as Good
from table
where
flag = 'G'
Group by Fruit

select Count(flag) as Bad
from table
where
flag = 'B'
Group by Fruit

COUNT (*) Inside Select
I am doing something wrong i would like to do a count inside this select for example:

SELECT th.tid, th.tname, th.tmain
(SELECT COUNT(*) as postnumber FROM forumpost AS post WHERE post.ptid=th.tid)
FROM thread as th WHERE tmain=1

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.

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.

Two Table COUNT/select
I need to count the total (using SUM) from one column in one table, where the a condition is set from another table.
so far I've been striking out with this:
Code:

SELECT maxbid SUM(maxbid) FROM `probid_auctions` WHERE probid_categories.parent = 1853

Select From Table And Count Results In Another
I have to tables table one containing airports and table two containg bookings. What I need to be able to do is count how many rows are returned form the booking table that matches each airport in the airport table.

So I might have in my airport table
Newcastle
Heathrow
Standstead
etc etc

and in my bookings table I have

Newcastle
Newcastle
Standstead
Heathrow
Heathrow

And what I want returned is
Newcastle(2)
Standstead(1)
Heathrow(3)

How can I go about doing this.

Select Query With Character Count
can you help me with creating a select query where the character count in a specific column is more than, say, 20 characters?

Doing A Select Statement With An Array To Get A Count
I posted this in the php forum and it was suggested I try it in the MySQL area instead. Sorry if this gets posted more than once.

So here is my problem. I have a series of mysql queries to allow users to set filters for the data that is returned. They are searching for clients (Site_ID) with projects (Request_ID). A single client can have multiple projects. I want to be able to count the number of projects that are returned from a query. Here is the tail end of that code...
