SELECT And Significant Digits
Using MySQL 4.0.12, is there a way to specify significant digits for a mathematical operation within a SELECT? In other words, the query "select 5/213" defaults to two significant digits (0.02) for the result. How can I specify the result attributes within a SELECT?
Select * Using Id List V.fast, Delete Using Id List Taking Hours.
I have a table of about 20 million rows, with about 20 columns. I want to delete 10 of these rows. I have the ids already, and id is the primary key so it should be simple - i thought. This query completed in 0.27 seconds - select * from users where id in (3811150, 4470160, 479422, 2491277, 9443643, 4594310, 2556165, 12075603, 2533320, 45737); This next query, however, has been running for several hours - how can there be such a discrepancy? Should i kill it and retry? delete from users where id in (3811150, 4470160, 479422, 2491277, 9443643, 4594310, 2556165, 12075603, 2533320, 45737);
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?
Selecting Item List And Count From Other Table
I have been failing at trying to get this query to work. Here is the query I can't get to work: SELECT cont.key_no, ( SELECT COUNT(1) FROM items itm WHERE itm.cont_key_no = cont.key_no ) AS item_count FROM containers cont WHERE cont.status = 'OPEN'; Here is a query I managed to get working, but it doesn't quite do what I want it to. It doesn't return a container and item count for containers that don't have items: SELECT cont.key_no, COUNT(itm.key_no) AS item_count FROM containers cont, items itm WHERE cont.status = 'OPEN' AND itm.cont_key_no = cont.key_no GROUP BY cont.key_no Here are what the tables look like: containers ---------- key_no status items --------- key_no cont_key_no If you can't tell from the examples above, I am trying to return a list of all 'OPEN' containers and how many items are in the container, even if no items are in the container.
Distinct List Of Parents With A Child Count Result
Parent (id, name) Child (id, parent_id, session_name) I'm trying to write a query that will have one output row per Parent. Each row will show: parent.id, parent.name, count of children for that parent AS children_count Some parents have no children. Those rows could return null or 0 for the children_count field. I know multiple methods external to SQL to solve the overall problem such as returning the join and counting where child.ids (for the same parent) is not null. ==>> but is there a way to do it in one SQL query that returns just the info I need?
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.
Order By All Digits
When i use Order by, it only uses the first digit then the second. I.E. It will give me 1,2,30,9 as the order when it should be 1,2,9,30. what query do i use to have it order for real?
Digits In Tinyint, Int
How large a number can be stored in a: tinyint int bigint are they the same as the C++ numbers Int8, Int16 and Int32? also what does the size refer to (tinyint 4) or (int 20) when I view the MySQL db in Dreamweaver?

List All Tables In Db Using SQL Select Command
I need to get a list of all tables in a MySQL database. (I'm running 4.0.1) atm. I need to get at the tablenames using a plain sql select statement. I can't use show table and i can't use api functions.It has to go through odbc and ado.net! Schema information ought to be available somewhere, right? (Of course I can't scan the directories for files either!) follow-up question: is there an ole_db driver for MySql?I could use its getSchemaTable function then.
Select A List Sorted By Date

No Digits Output/query > File ? > Spreadsheet?
Two questions: My query works fine but I need two things: a) How can I limit the number of digits outputed? I cannot find anything in my.cnf that seems to deal with this. I would like to limit the output to one digit past the decimal point ( a computation this field - that field). b) Getting the answer to my >select etc is just the first stage! I would like the answer to end up in a spreadsheet. mysql>select etc > /my/path/to/my file gives me an error message. I know in the command line output can be outputted to a file. Can the same thing be done in the mysql> command line? How? or what is the #command line command eg mysql select etc?
Select With Multiple Primary Keys Against List Of Values
I have created a method that automatically parses the metadata of a specified table and searches each field to effectively create a database search. The way it currently stands, it only supports tables with a single PK. Basically it returns a string that can be appended to the WHERE clause in a SELECT. i.e. "ID IN (1, 2, 3, 4)" Basically the PK field name and a list of matching PKs from the search. I realized though that this will break if I have a table with multiple primary keys. An elegant solution for this eludes me, and that is what I am asking for input on. Right now I can only think of returning something like : "(ID = 1 AND SSN = '123121234') OR (ID = 2 AND SSN = '432434321') OR ..." This obviously would become a monster if many results were returned. And if I did something like : "ID IN (1, 2) AND SSN IN ('123121234', '432434321')" This will either return false positives or nothing at all ... Is there a better way for me to create this conditional?
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
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.
Using A Field, Which Is A Comma Separated List, As The List In An IN Comparison Test.
The following query only reads the first character of a comma separated list stored in a field of the records being queried. The varchar field in table d named "display" holds 1,4 The query " select * from d where 4 IN (display) " tests false. If I change the field "display" to 4,1 Then the query tests true. It is either testing only the first character, or is stopping at the comma. I need this to test true if the value is anywhere in the list, what am I doing wrong here?
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.

SELECT COUNT (*) FROM Table
Newbie: SELECT COUNT (*) FROM table When I run the above query from the command line, it works fine. When I run it from my powerbasic program, I can't seem to get a reasonsible result. What type of result does count return? I get something that looks like this: [ CHR$(133) ][ CHR$(21) ][ CH... and the type is given as -5... 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 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

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...

I would obviously like to combine all 4 queries in to 1 so that I can get my 4 counts in a single,

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'?
Trying To Select Values From Column And Count Each Different One
say my column values are thus: 1 | 1 1 | 2 1 | 3 1 | 4 2 | 1 2 | 2 2 | 3 3 | 1 3 | 2 my select is like this: my $sth = $dbh->prepare("SELECT session_id, col2 From $table "); $sth->execute; while ( my @fields = $sth->fetchrow_array) { print qq( $fields[0] ); } I want to be able to show that there are three individual values (in col1) and that there are 9 values in col 2. I also need to show that (based on the number of values in col2 [relative to col 1]), that the average number is 3 Should I use select using UNIQUE (or some other value), or, should I select as shown but put it in a perl hash - or soemthing else?
