MYSQL :: Count Number Of Rows Returned?

Counting Number Of Rows Returned
I want to count the number of rows returned when I execute an SQL query. At the moment I am selecting them all and cycling through them:

$count=0;
$query = "SELECT * FROM swe_picgal WHERE cat="".$cat.""";
if ($mysql_result = mysql_query($query, $linkdb)) {
if (ExecuteQuery($linkdb, $result, $query)) {
while ($row = NextRow($result)) {
$count++;
}}}
print('Number of rows: '.$count.'');

Surely there is an easier way? I assumer mySQL will have a built in counting function?

Unions -- Number Of Rows Returned
I have this query:

SELECTcount(*)
FROMpa_album
WHEREcreator_id = 1001
UNION
SELECTcount(*)
FROMmb_post_tbl
WHEREauthor_id = 1001
UNION
SELECTcount(*)
FROMmb_post_tbl
WHEREupdated_person_id = 1001
UNION
SELECTcount(*)
FROMmb_thread_tbl
WHEREauthor_id = 1001
UNION
SELECTcount(*)
FROMevent_tbl
WHEREcreator_id = 1001

Which checks for a specific value in the foreign keys of a few tables. I would expect to see 5 rows in the results of this query, but I do not get 5-- I get a row for each SELECT that has a count > 0, but then I get only one row returned for all tables that have a count = 0. So if there is only one table that has a count > 0, then I get two rows-- value 0, and value 1.

How To Get Count Of Rows Returned While Using Group & Having?

but I am not sure if this syntax allows me to do what I am trying to do .

Limit Number Of Rows Or Characters Returned In A Text Field
I understand you can limit the rows of a recordset, but can you somehow tell a query to limit the rows (or characters) returned within just a text field?

I have a page that returns abstracts of many articles and I want to truncate the description for each to just 200 characters. Is there a way to accomplish this with MySQL?

Trying To Count The Number Of Rows In A Result Set After Query
The user fills out this form to sign up to the website, the form checks the database to see if the username has already been taken with the code:

Return A Count Of Number Of Rows Before Desired Row.
Anyone know how? find_in_set doesn't seem to be able to do what I want since I am not searching through an array but am actually running a query.

What I really want is to be able to select all until something = something. I've searched the realm of google but cannot come up with anything useful, and so I am wondering if maybe I don't know the right words to be looking for.

Zero Rows Or One Rows Returned, Same Data And Same Query
I have a query that produces a single row (as I expect) when I run it from the mysql client (mysql 4.0.18-Max/linux, also 5.0.19-standard/OSX-intel), or from sqlgrinder (osx, uses jdbc).

When I run it inside my application (a Java app connecting via jdbc), I get zero rows from this query.

I tried it under phpmyadmin, and once again I get zero rows.

Why do I get inconsistent results? Here's the query:

Limiting The Number Of Letters Returned

Restricting Number Of Characters Returned
is there a way to restrict the number of characters that are returned for a column. if I have a column and there are 400 characters for a particular record, and all I want to return is 50.

Rows Returned
EDIT:I resolved the problem...I was pushing these into an array...and whichever order I wanted, I just had to initialize it in that order.
How does mysql determine the order in which rows are returned when no order is given...for ex "select * from table where (id = '5' OR id = '6')?
I am extremely frustrated on why the same query on 2 different scripts returns rows in a diff order.

Limiting Amount Of Returned Rows?
How do I limit the amount of returned rows?

Lets say, that I want only the latest 400 rows (of e.g. 4034634 rows) -
is there a parameter for that like rownum in Oracle?

e.g. select * from someplace where rownum < 400 order by sometimefield?

MySQL Browser - Rows Returned In
Can anybody tell me what the "rows returned in" numbers at the bottom left of the results window signify, especially the one in ()? I have searched the docs to no avail!

Limiting # Of Rows Returned Per Page...
I'm building a db in MySQL using PHP, and I need to limit the number of results per page returned in a query. Note, I don't want to limit the query, just the number of results shown per page. So, if 100 rows are returned, I want to show 20 per page, and have the others linked at the bottom, like:

Page: 1 2 3 4 5 etc.

I did a search of the forum, but only found references to the LIMIT clause. This doesn't seem to be what I need, as I don't want to limit the number of rows returned in a query, just how the results are display. So I'm not sure if this would be done with SQL, or PHP.

Multiple Rows Returned Instead Of One (was "why This Is Happening?")

I have this select statement

PHP

$select="select video.id, title, description from video, category,

maincategory where maincategory.mainid='$selectcategory' AND

maincategory.mainid=category.mainid and

video.categoryid=category.categoryid and video.title like '%$searchterm%'

or video.description like '%$searchterm%' order by dateadded DESC";

if i put car in the searchterm which is the name of a video.title everything works fine and the result is shown only once... whereas if i put blabla in the searchterm which is included in the description of video.description two rows r returned for the same result instead of one.... why???

Count Number Of Columns
I have a table in which all columns except the primary key are type boolean (tinyint(1) in mysql). I want to be able to compare two specific rows, referenced by their primary key, and count the number of columns in which they both have a "1". As a second search, returning the names of these columns would be helpful too.

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:

I know I can do SELECT * FROM table but I don't really care about the data, I just want to know how many entries there are.

PHP - Can't Add Rows Past A Certain Id Number (127)
I've got a table which has about 70 rows in. The rows' ids start at 1, have a large gap in the middle, then range up to 127. If I try to add a new row with an autoindexed new id, I get the following MySQL error: duplicate entry '127' for key 1.

If I add a new row with a lower id, e.g. 6, there are no issues - it works fine. If I delete row 127, or give it a lower number, I can then add a new row as normal, but then the error happens again for all subsequent rows.

Everything was working fine with the page that adds new rows until it got to 127. Is this some kind of magic number I don't know about?

Retrieve Number Of Rows
I've got a large table with a lot of entries. only two fields, one's the key (which auto incs) and the other's a text field...if I want to just retrieve the number of rows in the table, what's the best way to do this?I know I could tell mysql to sort the table by the key row and then take the first one, but wouldn't this make it analyze the entire table (which would waste resources, especially considering that this table will have thousands and thousands of entries)? what's a better way to do it?

Number Of Table Rows
I have tried to answer this question by using Google but my search didn't bear any fruits, so to speak.

I am in the middle of designing my db and i have just thought that in some of my tables i think i will have 1000s of entries [rows] and if my web application with a db backend is successful it can turn into millions of rows [wishful] - so i wanted to know is there a limit in the number of rows for a table? I think not, but how will performance be effected?I am using a MySQL database, I am using a linux server not sure if this matters but microsft and i dont get along.

Counting Number Of Rows
Can anyone come up with a novel way of counting the number of rows in a table that contain no NULL values in the columns that each row contains?
Each row contains 200+ columns, so doing a "count" on each column, and then selecting the smallest value is not very practical.

Retrive A Limit Number Of Rows
How can I make the following query :

Limiting Number Of Rows In A Table
I'm trying to implement a basic log in a table. Instead of writing to a text
file on the server, I want to insert entries into a 'log' table. However, I
want to limit this table to only have the last 500 rows or so. How do I do
this?

Here's my pseudocode, but it seems as if there would be a better way:

logEntry($message){
insert message into table
get number of rows in table
if (numrows > 500){
delete from table where ((numrows - id) > 500)
}
}

Is that right?

Counting Number Of Valid Rows
We have many kinds of advertisers in our web service:
1.private
2. companies, of which some are members of local enterpreneur community
3. non-profitable communities

Company advertisers can select also a "line of business" while for others
its unavailable. We have a menu where we want to put all the lines of
business in alphabetical order WITH the information, how many companies
(that are ALSO members of local enterpreneur community) are in that line of
business. I made the query following some model. It looked like working,
but now I noticed it doesn't right results always:

SELECT business_lines.*,
IF(seller_id <> 'NULL' AND seller_type='company' AND
seller_membership="LocalEnt", count( * ), 0) as nr_of sellers_in_this_line
FROM business_lines
LEFT OUTER JOIN sellers ON line_id=seller_line_id
GROUP BY line_id
ORDER BY line_name asc

So I suspect that if not ALL companies int certain line are members, that
line results to enpty line. Is that true and how to fix this?

Count The Rows
I've built quite a few large join statements, which cross-reference 6 or 7 tables each. I'm using LIMIT to allow for pagination, which works fine.
However, I need to find out how many rows were returned in total, and don't fancy throwing in another join to count() the results with some where statements.
Anyway I can quickly find out what would've been returned without the LIMIT?

Getting Number Of Rows From Left Join Table
PHP

SELECT bulletin.id AS bid, bulletin.bulletinname AS bname, bulletin.bulletindesc AS bdesc, bulletin_post.id AS postid, DATE_FORMAT(bulletin_post.postingtime,'%M %d, %Y %l:%i%p') AS postdate, bulletin_post.bulletintitle AS ptitle, member.screenname AS mname, member.id AS posterid FROM bulletin LEFT OUTER JOIN bulletin_post ON bulletin.id = bulletin_post.bulletinid AND bulletin_post.postingtime = (SELECT MAX(postingtime) FROM bulletin_post WHERE bulletinid = bid) LEFT JOIN member ON member.id = bulletin_post.memberid WHERE bulletin.active = 1 ORDER BY bulletin.bulletinname ASC

My question is how would I get the count of rows if any from the bulletin_post table?
