MYSQL :: Count And Arranging Records

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 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?

           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 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?

Select / Count Not Showing Records ... Permissions?
I imported 600,000 records from SQL Server 2005 to mySQL.

I know they are in there -- I just can't see them!

When I do a SELECT, it processes for a while, and then returns nothing.

Same with a count, it sits there processing, and then returns a '0'

However when I do the same on a table I know has no rows, it definitely
comes back right away.

I'm logged in as root. Do I need to assign myself some permissions to
see these records? And the count numbers?

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:

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.....

#1136 - Column Count Doesn't Match Value Count At Row 1
I'm getting the above error with the following SQL Statement. I cannot seem to find the error in the code. The select statement does pull multiple rows.

I'm using my SQL version: 4.1.19

Any clue on why this isn't working?

INSERT INTO `Grants` ( `Project_Code` , `Grant_Code` , `Fiscal_Year` , `Capital` )

Column Count Doesn't Match Value Count At Row 1
I am getting the following error when I run my query.
Column count doesn't match value count at row 1

I have looked up this error and have checked and I appear to have the right number and names in my query. In the DB table I have 34 columns, and that is what I have in the query.

The last 4 in the query are for the names of the images being uploaded, but am not sure how this all works, so I don't know if I need them, but have them there until I know for sure. Comment, Purchase and Remarks are not used in this form, but I have added them so everything is being shown in the query. Code:

Count(*) As Count And TotalCount Of Count
data in myTable1

(n) country_id
(1) 3
(2) 1
(41) 1
(5) 2
(6) 3
(7) 4

data in myTable4

(time) param
(10 : 10) c=4
(10 : 12) c=2
(10 : 30) n=41&k=5
(10 : 35) c=1
(10 : 37) n=5
(10 : 50) c=2
(10 : 54) c=2
(10 : 55) n=1&cate=6
(11 : 12) c=2
(11 : 15) n=7
(11 : 20) c=1
I have data in myTables like the above.

I have the following code.

code

(select left(time,2) as hour, count(*) as count
from myTable4
where

left(param,1)='c'
and
substring(param,3,1)=2

group by left(time,2)
)
UNION all
(select left(time,2) as hour, count(*) as count
from myTable4,myTable1

where
left(param,1)='n'
and
substring(substring_index(param, '&', 1) ,3)=myTable1.n
and
myTable1.country_id=2
group by left(time,2)
)

order by hour
And the code above produces the following result.

result

(day) count
(10) 3
(10) 1
(11) 1
The following would-be code doesn't work correctly, but it will show what I want.

would-be code

and
substring(substring_index(param, '&', 1) ,3)=myTable1.n
and

All Records From Table A - All Records From Table B - Join Alike Records
I am by no means a SQl Jedi as will be apparent by my question, but I
can usually figure out a select statement on my own. I have one today
though that really has me stumped. I am working in MySQlL 5.

In My first select statement I get all my records from Table B
SELECT
`table_A`.`ITEM`,
`table_A`.`DECSCRIPTION`,
`table_A`.`UM`,
`table_A`.`PHASE`,
`table_B`.`Qty`,
`table_B`.`Calc` as calculated
FROM
`table_A`
Inner Join `table_B` ON `req_itemlist`.`ITEM` = `table_B`.`ItemID`

In my second statement I get my records that match in this case phase
401 in Table B and all my Table A records for phase 401.

SELECT
`table_A`.`ITEM`,
`table_A`.`DECSCRIPTION`,
`table_A`.`UM`,
`table_A`.`PHASE`,
`table_B`.`Qty`,
`table_B`.`Calc` as calculated
FROM
`table_A`

Left Outer Join `table_B` ON `req_itemlist`.`ITEM` = `table_B`.`ItemID`
Where
table_A.PHASE In ('401' )

Now I need to combine the Data of both recordsets. I need EVERYTHING in
Table B, but I also need All Table A records that match the phase
selection....

Can I write this one query or do I need to use a Temp table?

Delete Records Without Matching Records

Difference Of Count(*) From Count(1)
Is it true that count(1) is more efficient than count(*)? They say that count(*) still goes through all the records without needing to.

How To Fix "Column Count Doesn't Match Value Count At Row 1" ?
I've been trying to install a portal to my installation of Invision Power Board, and I keep coming up with this problem. I post here for two reasons: firstly is that no one is responding over at the portal creator's thread and I need help, second is that this error looks like a mySQL error that could be solved without the need of the creator if possible.

Here is the error returned:

mySQL query error: INSERT INTO `ibf_portal_box` VALUES (1, 'lang.last_topics', '<box><menu>10,20,30,50</menu>
<topics_show>10</topics_show>

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()?
Im trying to count the # of records with the same field (Name) is this the way to do it?

PHP

$Count = mysql_query(" SELECT count(ID), Name FROM REVIEW WHERE Name = '".$Name."'") or die(mysql_error());

Then to display the count all i need to do ia

PHP

echo $Count;

Count()
In my database I have Racing Events and Racing Results.

In the result database each racer that entered the race is giving a place.

I am trying to pull the each total number of races racer with id 1 was in.

Say the Count was 20. I also want to get the total number of people that raced in the same events as him. Say each race had 10 people that count would be 200.

In additional to that I want to count the number of time the racer with id 1 won money.

So say that field was called winnings - Winnings > 0

Using LIKE Within COUNT?
I am having problems with this query. I have it looking at a table of products sold data - specifically shoes. With shoes there is always the problem of fishing out the data for different sizes.

With the query below I am not sure whether I am able to use LIKE within the COUNT function.

I basically want the query to return a table showing the headings Product which contains all the products (grouped) and COUNTs the number of times each product size comes up.

Here is an example:

+-------------+-----------+-----------+------+-----+-------+
| Product | UK Kids 12 | UK Kids 13 | UK 1 | UK 2 | UK ... |
+-------------+-----------+-----------+------+-----+-------+
| Product 1 | 34 | 52 | 39 | 22 | .... |
+-------------+-----------+-----------+------+-----+-------+

And so on...

Here is the query I have currently however at the moment all it seems to do is return the same number (which happens to be the total of all the sizes - i.e. the total for that shoe model) for each product accross the whole row.

SELECT
SUBSTRING_INDEX(Product,',',1) AS 'Product',
COUNT(SUBSTRING_INDEX(Product,',',-1) LIKE '%Kids 12%') AS 'UK Kids 12',
COUNT(SUBSTRING_INDEX(Product,',',-1) LIKE '%Kids 13%') AS 'UK Kids 13',
COUNT(SUBSTRING_INDEX(Product,',',-1) LIKE '%1%(') AS 'UK 1',
COUNT(SUBSTRING_INDEX(Product,',',-1) LIKE '%2%(') AS 'UK 2',
COUNT(SUBSTRING_INDEX(Product,',',-1) LIKE '%3%(') AS 'UK 3',
COUNT(SUBSTRING_INDEX(Product,',',-1) LIKE '%4%(') AS 'UK 4',
COUNT(SUBSTRING_INDEX(Product,',',-1) LIKE '%5%(') AS 'UK 5',
COUNT(SUBSTRING_INDEX(Product,',',-1) LIKE '%6%(') AS 'UK 6',
COUNT(SUBSTRING_INDEX(Product,',',-1) LIKE '%7%(') AS 'UK 7',
COUNT(SUBSTRING_INDEX(Product,',',-1) LIKE '%8%(') AS 'UK 8',
COUNT(SUBSTRING_INDEX(Product,',',-1) LIKE '%9%(') AS 'UK 9',
COUNT(SUBSTRING_INDEX(Product,',',-1) LIKE '%10%(') AS 'UK 10',
COUNT(SUBSTRING_INDEX(Product,',',-1) LIKE '%11%(') AS 'UK 11'
FROM items_ordered,orders WHERE (Product LIKE 'Heelys%Shoes%') AND

(items_ordered.ShopperID = orders.ShopperID) AND (Date >= &#55614;&#57158;-1-30') AND (Date <= &#55614;&#57158;-8-31') GROUP BY Product;

COUNT()
I need to write a SELECT statement that will display the most popular
categories.

This means I need a 'category count' for each of the messages in the
messages table, and I don't know how to do this.

Here is the structure of the 2 tables:

messages table
id, title, message, category, thread, status, date_posted

categories table
id, title, sub_cat

I've tried the following:
select categories.id, categories.title, count(messages.category) as
count from messages, categories group by categories.title;

but 'count' only returns the total count of messages with a category
entry, and I need the number of times each category id is entered in
the messages table.

Any help is greatly appreciated. Also, does anyone have any online
references for learning more complex SQL statements?

Help With Count
I have 2 tables.

TableA
---------
int tableAPrimaryKey

TableB
---------
int tableBPrimaryKey
int tableAForeignKey

For each row in Table A, I am trying to get a count from Table B

select a.tableAPrimaryKey, count(*) as myCount
from TableA a, TableB b
where a.tableAPrimaryKey = b.tableAForeignKey
group by a.tableAPrimaryKey

This query returns the correct results, but only if the count is >= 1. I want a count for every row in TableA, even if the count is zero (or null...which I would count as zero)

The following query accounts for nulls, but the count ends up being 'one' instead of 'zero'.

select a.tableAPrimaryKey, count(*) as myCount
from TableA a
left outer join TableB b on a.tableAPrimaryKey = b.tableAForeignKey
group by a.tableAPrimaryKey.

Getting A 0 Count
I have a query, which essentially is this.

select count(visible) as cVis, Visible
from products

Visible can have a value of 0 or 1.. and I'm trying to figure out how to always get a count on both (Invisible 0 and Visible 1).

Right now if there's no count for one of them, it doesn't return it.

Count
I have a column that has about 50 possible values that can be put into it. I am trying to generate a query that can tell me how many times each of these values has been used.
Right now it's slow and painful going through and running 50 scripts like this:

SELECT count('col3') FROM tblStuff WHERE col3='widget1'
What would be nice would be to run a script that returned something like:

widget1 = 105
widget2 = 309
widget3 = 92
...
widget50 = 110

Count()
Is it possible to use count() twice in a query if I'm joining tables to count records in each table?

COUNT Is 0
I have the following query:

SELECT u.id,u.username, COUNT(p.id) FROM '.$db->prefix.'users AS u, '.$db->prefix.'posts AS p WHERE u.referred_by = '.$id.' AND p.poster_id = u.id GROUP BY u.id

The gist of the query is to list all members that were referred by a specific member and count the number of posts those referred members have made (this is for a forum). The problem is, this query will not show results if the referred member has made 0 posts.

Count(*)
I'd like to get a row count for a large table, but I've recently been considering if count(*) is too resource intensive? Is there a better way? A factor here might be that an exact count is not necessary, so if it's off by a few, I'm not concerned. Now, you might say "not an exact count?!?!?" You see, I was looking at SHOW TABLE STATUS, but I don't want to have to cycle through the rows to get to the table I'm interested in...

Count(*)
select count(*) from syslog.SystemEvents where message like
'%postfix/smtp[%' and (message like '%@carcass.us>%' or message like
'%@deadghost.com>%' or message like '%@phatho.com>%');
Above query returns error. Have no idea how to count something like this and
the manual is not helping. I'm thinking select it into a temp table and then
count? I have had no luck with temp tables either. They just don't seem to
work for me.
