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 Number Of Records?
If I have a sql statement like this: Code: SELECT id FROM `asset` WHERE field = 'value' LIMIT 20 , 40 Is it possible to know how many results there would've been if I hadn't used the LIMIT? Or will I need to do the above query and just count the results first, then apply the LIMIT and run the query again to get my limited set of results?

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.

Is There A Relation Between Number/size Of Total Tables & Table Operations In The Same Db
Does the number of tables and their total size in one DB influence the time needed by MySQL to perform a SELECT/UPDATE/DELETE operation on a certain table? I'm wondering about how I should backup information, which become obsolete on a monthly basis and therefore should cease to exist in the table. Just keeping the records in the table and append the new information would certainly slow down all of my queries. Now the question is: is there any disadvantage of creating new tables for each set of data(monthly) in the same database compared to simply creating an external file backup?

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. 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 ?

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 ?

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?

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?

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?

Lock Tables To Update And Delete, But Insert New Records
I'm trying to "lock" mysql tables - to prevent rows being updated/deleted - I still want to be able to insert new rows (legal reasons). I have toyed with the idea of changing the user permissions - can I simply change it so that no-one can perform an update on that table, even root?

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.

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.

Administrator Records Different In Query Browser
I'm using Innodb on windows server 2003. I noticed today that some of my tables are reported by MySql Administrator to have a far greater number of rows than what is return in a query for all rows. For example, one table shows 51,600 rows in Administrator but when I do a SELECT * on the same table from Query Browser I get a mere 5,293 (this is the correct or "real" number of rows) So, what's up? Why is administrator showing so many more rows? I've also noticed that each time I press the refresh button in Administrator the number of rows changes. one time it might be 50k+ then 30k then 43k, etc, etc. being a newb I'm a bit freaked out by all of this. I've heard that innodb can do some funny things, but this seems REALLY strange. I'm sure it's nothing, I just need to hear it from an experienced user
