MYSQL :: UPDATE Statement To A Single Position

Choose The Position Of A New Column In The Following Statement
Is it possible to choose the position of a new column in the following statement or do I have to use another statement like the one that followsALTER TABLE nikos_pages ADD COLUMN PageID INT NOT NULL AUTO_INCREMENT PRIMARY KEY

LTER TABLE TableName MODIFY ColumnName ColumnType NULL/NOT NULL AFTER OtherColumnName

Position Of A Record In A Given SELECT Statement
I want to make an iteration (on www) through some dataset (let's say - address book). One record maight be:
- third out of 1200 from city MyCity
- 134th out of 102000 from district MyDistrict
- etc...

Any ideas how to get position in any of those subsets in some elegant way? Till now I was doing

SELECT someID FROM address WHERE myCondition(ie. city=MyCity) ORDER BY neededOrder

and then iterated one by one through result searching for my ID and therefore knew it was ie 10th out of 120. Everyone will certainly agree that it's not elegant and far from optimized.

INSERT / UPDATE A Row By Its Position In The Table?
Is there a way to insert or do an update of a row (aka record) by its position in the table, for example, the 5th row of the table? I know you can select data in such a manner, using the LIMIT 4,1 clause, for example. Does this work with insert/update as well, and if so, what's an example SQL syntax?

Calculate Percentage In A Single Sql Statement
i am trying to calculate percentage of student came to computer laboratory in a single sql statement but no luck.

SELECT f.facultyInitial, COUNT(*) AS TOTAL
FROM attendance att
INNER JOIN academic a
ON att.academicNo = a.academicNo
INNER JOIN program p
ON a.programId = p.programId
INNER JOIN faculty f
ON p.facultyId = f.facultyId
WHERE YEAR(att.attendanceDate) = 񟭆'
GROUP BY f.facultyInitial
ORDER BY f.facultyInitial
alright, sql statement above will produce an output like below:

facultyInitial | TOTAL
---------------------
Account | 2
Civil | 1
FITQS | 3

what i want to do is, to put a percentage at the right side of the TOTAL column.

facultyInitial | TOTAL | PERCENTAGE
-----------------------------------
Account | 2 |
Civil | 1 |
FITQS | 3 |

here is my example to produce a percentage but it does not work

SELECT f.facultyInitial, COUNT(*) AS TOTAL, ROUND(COUNT(att.attendanceId)/TEMP.TOTAL_ROWS * 100, 2))
FROM attendance att
INNER JOIN academic a
ON att.academicNo = a.academicNo
INNER JOIN program p
ON a.programId = p.programId
INNER JOIN faculty f
ON p.facultyId = f.facultyId,
(SELECT COUNT(*) AS TOTAL_ROWS
FROM attendance TEMP
WHERE YEAR(att.attendanceDate) = 񟭆')
WHERE YEAR(att.attendanceDate) = 񟭆'
GROUP BY f.facultyInitial
ORDER BY f.facultyInitial

Using A Single Sql Statement To Group And Count The Groups
I'm trying to count the total number of items in a table that are grouped e.g. my table is a shopping basket and is like this:

basketID||orderID||productID||quantity
1||1||2||1
2||1||3||1
3||1||4||1
4||2||2||1
5||2||4||1
6||3||4||1

so product 4 appears 3 times, product 2 appears twice and product 3 appears just once

how do use an sql statement (if it is possible) to group the products then list them in the order of which appears most

so i could say

SELECT * FROM basket GROUP BY productID;

and that would group them for me, but i want them listed like

productID
4
2
3

(as 4 has the most occurances, then 2, then 3)

Mysql Sql Access 2 Servers In Single Statement
Is it possble to access databases in 2 server simultaneously in sql using the mysql client?

I can use sql to access multiple dabases on the same host1 server when I run 'mysql -h host1' but I cannot find a syntax to access databases on another server, which is supported on other db software.

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.

Performance Between Multiple INSERT Statements Vs Single Statement With Lots Of Data
$sql1 = "INSERT INTO mytable VALUES ("zzz","xxx")";
$result = mysql_query ($sql1);
...
$sql1000 = "INSERT INTO mytable VALUES ("zzz1000","xxx1000")";
$result = mysql_query ($sql1000);
vs

$sql = "INSERT INTO mytable VALUES
("zzz","xxx"),
...
("zzz1000","xxx1000")";
$result = mysql_query ($sql);

is there any performance difference between the 2?

btw, there could 1000-5000 row inserts.

What Would This Update Statement Be?
I have an array of ids formatted like 1,2,3,4,5

I have a table where there is a field that selects maybe a few of those ids, and is formatted like this: 1,3,5

Update Statement
I am using excel to update an online mysql table. I am having an issue with my update statement and I don't understand why. When I run the statement, I am getting a run time error. In the description of the error, the statement is reading as I would expect it to - but it is not working.

usqlstring = "(UPDATE company set company = '" & ucompany & "' WHERE prospect_id='" & updateid & "')"

Update With If Statement
I'm trying a statement which I cannot figure out what I'm doing wrong on. I've tried every combination that I can think of and stared myself blue with no success.

update cdr set Cost=if(mod(BillSec,6)=0,int(BillSec/6),int(BillSec/6)+1)

The idea is to update Cost with a value depending on the result of a formula. It's an empty field which gets a computed value from other fields. cdr is the table.

Update Statement
here is a update statement I have...

UPDATE support_test
    SET cat_id=42
    WHERE cat_id = 4

It works fine, only thing is I need to update more numbers but I don't want to overwrite the updated numbers.  Example, I want to update 42 to 6 but want to update the original 6's to 12. I have about 30+ numbers that need to be changed, any way to go about this?

SQL-Update-Statement
I have to update all UA-fields in the table idrz_kennzahl with primary
key idrz, where the same idrz in the table per_verwaltung with the
field Amt=12 is.

I designed following statement but it doesn't work:

update idrz_kennzahl
set UA=1234
where
idrz_kennzahl.idrz =
(SELECT per_verwaltung.idrz from per_verwaltung where
per_verwaltung.Amt=12

Update Statement
I am currently updating a table and increasing a column value by 1, the problem is that he don't increase 1 but it does increase the double of the value specified.
Why does it performs the update like this? And how can i solve this problem?

SQL Statement Syntax used: UPDATE table_name SET column_name=column_name+1 WHERE id=1

Version of MySQL: 4.1.7 for Windows installed in Windows 2003 Server.

Update Statement
i have the following problem. in a table i have 3 columns. first a nvarchar field (6 characters) which is filled with point of sales (pos) numbers. the second one is an ip-adress like 10.192.17.30. the third column i want to create based on the second column, means i have to substract e.g. 3 of the ip-number. e.g. the ip-numer is 10.192.17.30 so in the third column should stand 10.192.17.27.

Update Statement
I have two tables, and I want to take data from one table, and overwrite it onto the second. Unfortunately, my SQL is pretty weak.

The first table has a mediumtext column and a id (primary key) column. The second has an id (the same as the first), a number, and a mediumtext column.

I want to take the contents of the mediumtext field with the highest number and replace the contents of the field in the first column with it with the same id.

My instinct is to do it this way:

update forum1post p
set p.pagetext = (select query1.message
from (select pe.message, max(pe.editnum)
from forum1post_edits pe
group by p.postid) query1)
where p.pagetext = 'Why did you all flame my topic. Screw your ****ing forums.'
and p.postid = pe.postid

However, that does not work, as pe is not recognized.

SQL-Update-Statement
I have a litte problem with my sql-database!
I have to update all UA-fields in the table idrz_kennzahl with primary
key idrz, where the same idrz in the table per_verwaltung with the
field Amt=12 is.

I designed following statement but it doesn't work:

update idrz_kennzahl
set UA=1234
where
idrz_kennzahl.idrz =
(SELECT per_verwaltung.idrz from per_verwaltung where
per_verwaltung.Amt=12).

Update Statement
UPDATE `zipLocations` SET `z_zipCode` = '06001' WHERE `z_zipCode` =6001 LIMIT 1 ;

Field Type Attributes Null Default Extra Action
z_zipCode int(5) No 0
z_cityName varchar(50) No
s_stateAbbr char(2) No
z_countyName varchar(50) No
z_areaCodes varchar(50) No

I even went through phpmyadmin found the row clicked on the edit button for that row and updated it. and it still doesn't update.. im' thinking it has to do with the data type being INT...

Why doesn't it update it ?.. It says it was successful.
Affected rows: 0 (Query took 0.0002 sec)

Update Statement
UPDATE products_to_categories SET products_to_categories.categories_id = 666
FROM products, products_to_categories

Update Statement
Can someone please let me know what is wrong with the following statement?

UPDATE user_attribute, user
SET user_attribute.value = user.login
WHERE user_attribute.userid = user.id;

I keep getting a syntax error but don't see the mistake made.

Update Statement

works fine on my machine her ebut on server i get error..

Lock Wait Timeout Exceeded; Try Restarting Transaction Even In Single Db Single User
I am updating few databases all which I keep as one transaction using .net connector. The best part is that I can still run into this error of "Lock wait timeout exceeded; try restarting transaction" even though I am the only single soul using my database at that time. Any idea how to over come this problem.

Conditional Update Statement
I have a table with a field of ID numbers. I want to update this field and replace the ID numbers. For example I want every record that currently has the ID number 2,5,6,or 9 to be replaced with a 1. Every record with 1 or 4 to be replaced with 2 ...

I can't seem to form the update statement to do this. I can do them one at a time but this won't work because if I change 2,5,6, and 9 to 1 then when I run then update for 1 and 4 it will change them all. Does this make any sense?

I want some way to be able to use a condition...if id=2 or 4 or 6 set it to 1 and if id= 1 or 4 set it to 2.

My failed attempt:

mysql> update client_software set software_id=1
WHERE (software_id=2 or software_id=5 or software_id=6 or software_id=9)
AND software_id=2 WHERE (software_id=3 or software_id=7 or software_id=8)
AND software_id=3 WHERE (software_id=1 or software_id=4);

DELETE,UPDATE Or Other Statement In WHERE
I would like to let my admins write WHERE statements. . In panel where you can see all users of my site, admin should have input where he can put some filters in WHERE statment. E.G. standard query is
SELECT login FROM USERS .
and admin would write age > 18 and male = 'f'
. php script would conact it and it would execute
SELECT login FROM users WHERE age > 18 and male = 'f'
I have question about security of this solution. Is possible to put in WHERE statement sobe dangeurous statemetns like DELETE of UPDATE?

Update Statement Problem? Plz Help.
I've a simple doubt of whether can or can't i update two tables by using joins as below. the below update statement matched 2 rows one each for two tables but didn't update.

mysql> update audio join pcr_info on audio.audio_sid=pcr_info.pcr_sid set audio.
audio_pid=4896,audio.audio_prgm_num=3,audio.audio_type="MPEGLayer1",audio.audio_

Very Slow Update Statement
I am having an issue with an UPDATE statement that takes a very long time. I am using
1 table in a schema to update another table in another schema. Below are the create statements and the update statment I am using. Table and column names have been changed to protect the innocent :) Code:

Special UPDATE Statement
UPDATE some_table st SET some_page_no=((select count(*) FROM some_table WHERE some_table_id<st.some_table_id and some_id=st.some_id and some_type='OK') div 10)+1 WHERE some_id=345 and some_type='OK'

I want to use the above to make a fast page index (10 on each page). I had something similar in mssql and it worked, but in myssql I get this error:

"You can't specify target table 'some_table' for update in FROM clause"

What have I done wrong or can the above simply not be done?

Select + Update In One Statement
I have these statements.

$selectdata = "SELECT * FROM imagetrack WHERE fimsid = ".$_GET["fimsid"]." AND name = '".$_GET["service"] . "'";

$query = mysql_query($selectdata) or die(mysql_error());
$update = "UPDATE imagetrack SET seen = seen+1 WHERE fimsid = ".$_GET["fimsid"]." AND name = '".$_GET["service"] . "'";

Basically i was wondering if there was a statement where i can select everything and update the seen in one statement.

Conditions In UPDATE Statement
i have some data to be updated in a specific row - WHERE id=1

data:
$min_time, $max_time, $time, $attempts

so, i would like to calculate new avg and replace min_time with new value, if new min_time is smaller then that one stored in the database.

"UPDATE mytable SET
avg=(avg*attempts+$time) DEV (attempts+1),
min_time=**here i could use help** ??IF(min_time>$min_time)$min_time ELSE min_time??
**and similar with max_time .

Select And Update Statement
Is it possible to combine a select and update statement in mysql? If
so, what is the syntax.

SQL Statement For A Selective Update
I have a table with a field called 'imagepath', in this table is data represented by the two following path types:
1. J:DIRDIRDIR
and
2. 172.21.2.7DIRDIRDIR
What I need to do is udpdate the data to represent the following:
172.21.10.1DIRetc.

In other words don't update the dir paths just update the mapped dirve and old unc to the new unc.

UPDATE Statement Doesn't Work
TABLE - abc

ID NAME
___________
1 hello
12 abc

UPDATE `abc` SET `ID`='5' AND `NAME`='hello' WHERE `ID`='1' AND `NAME`='hello'

wherenver I try to update this table using above sql statement, it doesn't work. I just get "Row match:1 Changed:0" message.

If Condition In Update Statement
I have a table with three fields - stockLevel, backOorder and allocated (there are other fields but these are the inportant ones here).

Is it possible to create a SQL update query that will deduct a qty from the stockLevel if there is sufficient stock and if not deduct as much as possible and put the this amount on allocated and the remainder on backOrder?

Long Old UPDATE Statement
I have the following SQL which gives me the row Im after

SELECT *
FROM staff, staffemails
WHERE staff.users_username='$user'
and staff.staff_id = staffemails.staff_id

thing is I now want to perform an update on the result of this query. Ive tried

UPDATE staffemails
SET is_registered ='0'
WHERE staff.users_username = '$user'
and staffemails.staff_id = staff.staff_id .

UPDATE / JOIN STATEMENT
i have problems after updating mysql from 4.x to 5.0.19. This statement should update about 3000 rows but it only does 15 but there are definitely another 2000 rows with an older date and matching nr!

UPDATE tab1,tab2
SET tab2.newdate = NOW()
WHERE tab1.nr=tab2.nr;

I tried the variation with inner joining tab1 as well. same result.
Does anyone has an idea solving this problem? Perhaps itÂ´s a bug?

Update Statement Not Working
Why does this simple update statement not work with a mysql version 3.23.49,
it does work when using 4.0.24..... ?

UPDATE listitem,vjbase,list SET listitem.showsec = 7 WHERE listitem.id_vjbase = vjbase.vjbase_id AND listitem.id_vjbase = 3 AND vjbase.id_viduser = 61000 AND listitem.id_list = list.list_id AND listitem.id_list = 1 AND list.id_viduser = 61000

MySQL/PHP - SQL UPDATE Statement
I am trying to update one field in my table in MySQL. I cannot get this field to update. Can someone possibly tell me what is wrong with my SQL statement?

$SQL="UPDATE umcritsurv SET IQ_Use_Q9='$IQ_Use_Q9' WHERE fldAuto='54'";

Help With Simple SQL Statement To Update Zipcodes
I have a varchar(5) field in a database called 'zip_code'. I imported some zipcodes from an Excel spreadsheet, but the spreadsheet had truncated any zipcode that started with a "0" and removed the zero, so the correct zipcode of "08993" was incorrectly placed into the record as "8993".

Would someone help me write a SQL statement to run on the field zip_code that would look at the data, if it was four characters long, add a "0" to the start and keep the remaining four characters in place?

QUERY One Table And Update Another In ONE Statement?
ZIP_CODE:
zip_code
latitude
longitude

customers:
customer_id
...
zip_code
latitude
longitude

The lat and long in the customers table is blank. I want to lookup customers' zip code in the ZIP_CODE, get the related lat & long and update the customers table with that information. The result being that after this query is run, the customers table now has lat & long data.

CASE Statement In Update Command
I'm trying to update one table (tbl_usage) based on information from another table (tbl_subscriptions) joined by the userID. The usage table tracks the number of times a user hits a page, and decrements the count each time. When the user has a zero count, they are redirected to a warning page.

Each week the count is reset depending on what type of license they have (licenseType) and how many of those licenses they've bought (numLicenses). A group license (G) gives them 100 hits, and an individual license (I) gives them 5 hits.

I'm trying to use a case statement to perform this count reset operation, but I can't seem to get it to work. The following case statement works just fine: Code:

Convert A Nested Update Statement
i have a nested update statement in my sql server as follows
UPDATE DIM_EVENT .

SET INVOICE_AMOUNT =
(SELECT SUM(INV.INVOICE_AMOUNT_TOTAL)
FROM INVOICE INV
WHERE INV.INVOICE_REFERENCE_NUMBER = DIM_EVENT.OBJECT_ID
AND INV.INVOICE_AMOUNT_TOTAL IS NOT NULL)
WHERE DIM_EVENT.EVENT_TYPE_CODE IN ('OFULN', 'OAUTH', 'CRDRL');
what is the equivalent in MySQL.

Nested Select In Update Statement
my nested Select-Update-Statement doesn't work. I think it's because the SELECT-Statement returns an empty set.. is there a posibillity to run this statement if there is no empty set and insert NULL if it is? Or is there another error at all?

CODEUPDATE proj_user_suche SET acronym = (SELECT name FROM acronym LEFT OUTER JOIN link_acronym ON acronym.id_acronym = link_acronym.id_acronym WHERE projekte_nr="23") WHERE id_proj_user_suche="17"

Convert SELECT Statement To UPDATE
How do I convert the following SELECT statement to UPDATE statement? If I'm not mistaken, UPDATE statement could not involve more than one table.

SELECT * FROM F0116 LEFT JOIN F0101 ON F0116.ALAN8=F0101.ABAN8 WHERE F0116.ALCTR='' AND F0101.ABMCU='1'

MySql Update Or Insert Statement To Modify A Word In All Caps
I have a field in my database called Subtopic. In this field I have a word LITERATURE in all caps. I need to change the word LITERATURE to LITERATURE followed by a colon then an empty space. Can someone give me the MySql statement I can paste into phpMyAdmin to make this change? Note: The Subtopic field contains the word "literature" but not in all caps because the Subtopic field is part the database that is an encyclopedia. Therefore, I want to change ONLY the word LITERATURE if the word LITERATURE is in all caps.

What Position A Certain Row Is
I have a table where i often grab and remove rows. How do I figure out which position a certain row is?

For example:

title description
---- --------
hello asdfadsf
test asdfas
me asdfasd

Say i do a select statement for and sort by title, ASC how do i find what position a certain row will be?

How To Specify Position
If I want to assign 'a' to the first row of varname1, and 'e' to the second row of varname1, ... Basically, I want a way for indicating position.

Get Position Of Row
maybe it's a simple question for MySQL gurus, but I couldn't find answer anywhere.
Has anyone an idea how to get POSITION of a specific record in a returned result set (in MySQL 4.1)?

For example, result set looks like

Peter
Sarah
Bron
Jack

How to persuade MySQL to give me position of Sarah (2) for example? Maybe it has something to do with subqueries or temporary tables with numbered rows, but I don't know exactly how to do that
