MYSQL :: Query Total Records In 1 DB With 5 Tables:

Total Like Records Query
Ime probably missing the boat here so please be patient. I am trying to create a query to display the total number of records with the same parent name.
Eg
Total records for author Eddings = 10

So in effect i want to count all the entries and display only the numeric figure of books for that author. I think its supposed to look something like:

Select
sum(Eddings) $total
From books

LIMIT (total Records)
If I have a query with LIMIT what will the best way to find out the total number of records returned by the same query but without any LIMIT? Will it be different solutions for different versions of MySQL?

Is that possible to get this number in the same one query with LIMIT?

Counting Records In 2 Tables Using 1 Query
I have these 2 queries.

SELECT count(*) gifts
FROM gift g
WHERE g.this and g.that

SELECT count(*) events
FROM events e
WHERE e.this and e.the other thing

is there a way to put these into one query.....

SELECT count(g.*) gifts, count(e.*)
FROM gift g, event e
WHERE . . . .

so far nothing seems to be working .....

1 Line Query To Delete Specific Records From Multiple Tables
On clients machine, currently to delete on trainee record it runs 10 queries to delete records from 10 tables. At the time of running all queries, server shows (104) Connection reset by peer. An error condition occurred while reading data from the network.

I think it because of running 10 queries at a same time. Is there any possibility that through one line of query we can delete record from 10 tables.

I've tried following query

DELETE FROM table1, table2, table3, table4, table5, table6, table7, table8, table9, table10 WHERE empID = 11;

But it gives ' error in query.

How To: Get Total Numbers Of Tables In A Database
I know how to get names tables from a database, using SHOW TABLES.
but I want to get how many tables are in a database.
I'm working in C# and I would like to get tables name over a string array variable, so before I get names I need to dimension this variable base on database's tables quantity.

Query Pages Printed By Percentage Of Total?
I'm very new to MySQL and have a query I'm trying to achieve, if anyone can point me in the right direction, I would greatly appreciate it. I have a table created to store print job logs from a print server:

Table = printLogs

logNum mediumint(8)
logDateTime datetime
docNum tinyint(3)
docName varchar(200)
owner varchar(25)
printerName varchar(25)
printerPort varchar(50)
sizeInBytes varchar(50)
pagesPrinted smallint(10)

What I'm trying to do is find a query that, based on a 'printerName', will display 'owner' and percentage derived from the total number of pages printed to that 'printerName' for a given date range.

Something like this:

+--------+--------------------------+
| owner | Percentage of total jobs |
+--------+--------------------------+
| Mary | 50% |
| John | 30% |
| Kim | 10% |
| Sue | 10% |
+--------+--------------------------+

Each row of the table is a different print job and can be one of about 20 different owners who have printed any number of pages to any of 10 printers. The main reason for the query is to be to determine which group/owner uses each printer the most.

How To Get The Total Number Of Rows With A Query "limit" ?
I would like to paginate the results of a query on several pages. So I
use a query with a limit X offset Y to display X results on a page,
ok.

But for the first page, I need to run the same query with a count(*)
to know how many pages I will get (number total of rows/ X).

The problem is my query is very slow (maybe 5s) because there is much
worch to do, and on the first page, I need to run this query twice
(not exactly, but ...) so the page is very very slow to load.

My question is : is there a function to get the total number of rows
even on a query with "limit" ? Or what could I do else?

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?

Transfering Records Between Tables
I have two tables 'gamestats' and 'gamestats_archive', i want to move x records from gamestats to gamestats_archive and then delete the records that have been moved from gamestats.

Here is the queries that I am using:

first this runs:

INSERT INTO gamestats_archive SELECT * FROM gamestats WHERE date='$selecteddate' ORDER BY entry_id ASC LIMIT $maxstats

then this one:

DELETE FROM gamestats WHERE date='$selecteddate' ORDER BY entry_id ASC LIMIT $maxstats

the problem is that the delete query is not deleting the records that have been moved, its deleting different ones. does anyone know why this might be happening?

Records From Linked Tables
can anyone help me with an sql statement that will work for mysql to take data from two tables where the two tables are linked with a common field.

Deleting Records From Multiple Tables
I'm trying to delete an article and the corresponding comments to this article

articles
+------------+
| article_id |
+------------+
| 13 |
+------------+
| 16 |
+------------+

comments
+------------+--------------------+
| comment_id | comment_article_id |
+------------+--------------------+
| 1 | 13 |
+------------+--------------------+

mysql_query("DELETE articles, comments
FROM articles, comments
WHERE articles.article_id = 16
AND comments.comment_article_id = 16");

Because article 16 has no comments, the article doesn't get deleted. If I try to delete article 13, this will work.

So how can I delete article 16 even if there are not any comments at all?

Join 2 Tables And Limit Records From One
i've got 2 tables:

Gallery
Gallery_Id,Gallery_Name

Images
Images_Id,Gallery_Id,Images_Filename,Images_Width,Images_Height

I'd like to select all galeries from Gallery and join Images to each gallery but i'd like to limit 3 images per gallery this code list all images from all galleries, i suppose that i must try with subqueries, am i wrong ?

SELECT a.Gallery_Id,a.Gallery_Name,b.Images_Id,b.Images_Filename
FROM Gallery AS a INNER JOIN Images AS b ON b.Gallery_Id=a.Gallery_Id

Time Difference Between Records From Two Tables
I have two tables with data from two separate data loggers. The timestamps of the records are not perfectly synchronised (eg. 2005-07-11 22:50:00 and 2005-07-11 22:49:58). All data must be joined to one table and all records that are out of sync by more then 30 seconds must be rejected. I tried somethig like this: Code:

Can't Update Records When Using Linked Tables In Access
I have a linked table to MySQL 5.0 through MS Access 2003 that utilizes a timestamp field in order to prevent the #Deleted signature happening everytime I create a new record. However, when I attempt to update a previous record I receive the error message: "Reserved error (-7776)" and am subsequently prevented from updating any records. Please note, there are no errors when creating new records, only when I attempt to update an existing one. However, if I remove the timestamp field, updates occur without error. Has anyone else encountered this issue? How might I rectify it?

Would MySQL Handle Millions Of Records Tables
I already found on the MySQL web site that some users did have good
results with tables of some millions records.

But, what I want to do is store some hundreds millions records in a
table. 190 millions to start and maybe a lot more after. Does someone
already use MySQL with such a quantity of data ?

I was also asking myself how a simple SELECt query like this one below
would perform on such a table.

SELECT * FROM MyTable WHERE MyPrimaryKeyField = Value;

I think that with indexes this shoudl be fast despite the fact that
the table is huge.

An other kind of query i'd like to do is :

SELECT Count(*) FROM MyTable WHERE ABooleanField = True;

I expect this one to take several minutes, maybe hours. Is my guess
right or could it be lot faster/slower ?

Join 2 Tables And Select Only Most Recent Records
I have been wrestling with a way to select only the most recent records for a group of clients without using a subselect. I have two tables: cdp_clients and cdp_level_records related by 'admitid'. For each cdp_client there are multiple cdp_level_records, each with a different 'level_date'. I want to select only the most recent cdp_level_record for each client in cdp_clients.

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:

Get List Of Tables Containg Specific Records
I have a database with 20+ tables that contain data from various instruments. Samples can be measured on any combinaiton of instruments and I would like to be able to query the database to find which tables have data for a specific sample, with the table names being returned to build a dynamic web form for selecting and viewing data.

I can build sort of brut force queries via php to do this to mitigate re-writing webpages when additional tables are added, but it seems to me there should be an elegant solution (or at least brut elegant) to this.

Copy Records From Tables To Remote Database
there ara two mysql server server1 and server2. server1 ip adress is 192.168.1.2 and
server2 ip adress is 192.168.1.3. both servers have same database. i want to copy records server1 to server2 have can i do this?

Deleting Records Upon Query... (!?!)
Sorry for the confusing thread title. Here's what I am trying to do...

Read the last six added records for a particular criteria, and delete the rest. Now consider I have around 1000 unique "criteria" and this query is executed a few times a day for each unique... should I delete it on each read or put it in a cron job and schedule it for every night.

Here's a sample MySQL syntax for my selectquery:

SELECT * FROM table1
WHERE field1 = sometext
ORDER BY some_time_field ASC
LIMIT 0,6
So the questions, again, are:Can I join this SELECT query with a DELETE, and delete all field1s with "sometext" which were not selected by the query?If I can't, how would I do it with a seperate DELETE query? i.e. Leave the last six records for field1 = sometext and delete the rest?Do I really need to order by some_time_field? Or does MySQL have an internal schema to sort records by their "internal" creation date?

Query Help Looping Through Records
The below Query loops through two tables in mysql and outputs all records where a match_date in a reports table (re) is equal to a match_date in a fixtures table (f).

Now this works well, but what I want to do is say to my query is find all of these dates BUT

- As soon as the FIRST f.date is found that does not have a re.date matching it output that information and limit it to 1 .....

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?

Query Cannot Retrieves All The Records
I've got this problem, this query is used to create a combo wich display all months where at least a news is been submited (a kind of hostory menÃ¹), the fact is that it can display max the months wich correspond to the 107 record submited.

The query:

select date_format(data,"%b/%Y")as textMonth, month(data)as month,dayofmonth(data)as day,year(data)as year from archivio where category = "Rassegna Stampa" group by month

Just to be shure I've also tried the query above on mysql browser, and the result is the same. Can you tell me if there's a kind of limit?

Query And Non Existent Records
I have a mysql table texts which keeps textlines in different languages.

columns: textId, languageCode, textline

The application adds records for specific languages as:

textId 1
languageCode: EN
textline: "Username"

another record could be:
textId 1
languageCode: DE
textline "Anwendername"

Now at a certain pojnt in the app I have to check whether for a specific textId there are textline filled in for specific languageCode. For example: Is there a textline for records with textIds 120, 124 and 134. And are these records present for EN and FR (French). I can query as:

Select count(*) from texts where textline != '' and textId in (120,124,134);

But what when the records are there in ENglish and German but not in French?

Any ideas how to solve this?

Update A Set Of Records In One Single Query
My records contain a position, from 1 to n. This position is not the primary key.
In normal conditions, the position of this records should be as follows:
1, 2, 3, 4, 5, 6, 7, 8, 9 . etc...

One of my utitities is meant to check the consistency of the table -
one of the things it has to do is scan the table as follows:

SELECT position FROM employe_records WHERE employe_id = ? ORDER BY position

From the result of this query I verify each entry (JDBC) one by one, looking for inconsistancies. In a for() loop I look at the value of position and check that they start from 1 and are incremented by one for each record.

At the first inconsistency I come accross I want to run a query to update the records so it is consistant again - it is something like this:

UPDATE employe_records SET position = updatedValue FROM
employe_records WHERE employe_id = ? ORDER BY position

This is not valid query of course - my question is what should my query look like?! How can I make 'updatedValue' incremented by one automatically so each of the records are updated from 1 to n.

Select Last N Records Matching A Query.
I am trying to select the last n records in a database which conform to criteria selected by a user. I gather that there is no "BOTTOM" equivalent to the "SELECT TOP" command. I've tried "SELECT...

Flag Records Not To Be Reused After Query
I'm a MySQL novice, and I don't even know if there is a way to do this.

I have a simple table containing just 2 fields and about 15,000 entries...one contains an ID (which is just an incremental number) and the other a phrase.

I will be doing queries selecting 50 random entries from the table. Somehow, once those 50 are selected and returned, I would like to flag them so that they cannot be selected again UNTIL I exhaust the entire list. So, I'd like to get 50 random at a time, until all 15,000 are gone, and then start over.

If that isn't possible, I suppose I can just select the first 50 every time and delete the first 50 when I am done.

Duplicate Records Delete Query
