MYSQL :: Conditions In UPDATE Statement

Combining UPDATE Statements With Different Fields And Conditions
I'm slightly paranoid that I haven't unearthed an existing answer to this question, but the ones I have been able to find didn't have two different variables requiring two different conditions. Basically, I want to know if it's possible to combine the following UPDATE statements into a single query:

UPDATE table SET field1 = field1 - n WHERE field 1 > x
UPDATE table SET field2 = field2 - n WHERE field 2 > x

.......

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
WHERE products_to_categories.products_id = products.products_id
AND products.products_model = 'PAC-P6512'

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
this works on my machine but not where my site is hosted. They do use an older version of mysql could that be problem

update inv, newprice set inv.cost = newprice.price where inv.itemcode = newprice.itemcode

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

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_
sr=44.1,audio.audio_mode="1_0",audio.audio_bitrate=320,pcr_info.pcr_pid=49 where
pcr_info.pcr_prgm_num=3 and pcr_info.pcr_sid="2501" and audio.audio_pid=4896 an
d pcr_info.pcr_pid=49;
Query OK, 0 rows affected (0.00 sec)
Rows matched: 2 Changed: 0 Warnings: 0

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.

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.

UPDATE Statement To A Single Position
I am running into problems trying to write SQL to update a single position within a field for throusands of records.

Thousands of records on a table have an incorrect number in a field (UIDY) and I am looking for the most simple way to update them all.

If it were only a single record, I would execute the following:
Update MF_VEND_ADDR_DOC set UIDY = '&4027&7608&7607&1609&VC19&VC19000055&&0&999&M' where UIDY = '&4025&7608&7607&1609&VC19&VC19000055&&0&999&M'

The only difference in those two lines is that I want to change the &4025& to &4027&.

Does anyone know of a way to update thousands of similar records by updating the 5th position in the UIDY field, thus eliminating the need to list out each UIDY value?

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.

Where Conditions
I am using MySQL phpmyadmin on my server. I would like some examples of different conditional codes to retrieve info from my tables.

LIKE Conditions
Basically I have a table, with a column which holds a list of related tags separated by spaces. The user can search for a row using a key word that will search this column (and the column named header too) and return if the keyword appears in the tags (or heading)... I tried to achieve this by using the following SQL but it actually returns every entry in the database... I have never used "LIKE" before so if someone could give me a slap and say I am doing something stupid that would be awesome .

SELECT * FROM VIDEOS WHERE VIDEO_HEADER LIKE '%$seachText%' OR VIDEO_TAGS LIKE '%$searchText%'

WHERE Conditions
I'm trying to optimize a search and I'm wondering if anybody knew whether the order of the conditions in the WHERE clause actually matters. Is it parsed from left to right? If so, then should I put the conditions likely to eliminate the most records first, followed by those that will eliminate the least?
Also - I need to join several tables for this search (1 master table that contains user info and about 7 secondary tables that include additional information on users) and I am trying to decide whether I should do the joins one at a time and eliminate users in a series of steps (to prevent getting an overly large table), or if I should evaluate and combine everything in a single statement. The problem is I don't really know what the parsing order of the SELECT statement is.

2 Of 5 Conditions Match
I need my query to match at least 2 of 5 given conditions.

Example:
I have conditions
content REGEXP 'A'
content REGEXP 'B'
content REGEXP 'C'
content REGEXP 'D'
content REGEXP 'E'

I need database to return this entry only if at least 2 conditons are true.

Need Help With Multiple WHERE Conditions...
i'm wondering if anyone knows how to have multiple WHERE conditions...i'm using php/mysql as my programing languages...

example --> SELECT * FROM table WHERE rid=$ride && uid=$userid && accepted=Ɔ'

I need help selecting rows where all three of the conditions above are met...anyone knows how to do this?

MySQL 5.0 And OR Conditions
I have heard that version 5.0 of MySQL has performance gains for "OR" conditions. Can anyone confirm this? If so, how significant are the performance gains over 4.1?

For instance, I am referring to something like: SELECT * FROM some_table WHERE this_thing = 'something' OR that_thing = 'whatever';

Search On Several Conditions
I want to retreive data from a table on several conditions in order; for example;

All i am trying to do is select all records on the following condition;

User_id = variable AND (Profile = "variable" OR Profile = "Both") ORDER by hits in DESC

I came up with this statement but no matter what i do i cannot get it to produce the result above

"SELECT * FROM links WHERE user_id='$user_id' AND (profile='$mycurrentprofile' OR profile='Both') GROUP BY total_hits DESC"

Can anyone offer me any help please, would really appreciate this as its doing my head in.

BTW, the following statement seems to work so not sure whats going on ? Only thing i can think is that its screwing up if total_hits above is equal 0 ?

"SELECT * FROM links WHERE folder_id='$activefolder' AND (profile='$mycurrentprofile' OR profile='Both') GROUP BY title ASC"

Sums For Two Different Conditions
I want to combine the following 2 queries into 1 query where it would give me 2 results (proflad and proftot) but don't know how

select sum(return-inv)as proflad
from allbets where com="lad"

select sum(return-inv)as proftot
from allbets where com="tot"

Transactions And Race Conditions
In an application I'm developing, I'm at a point where there needs to be tight integration of application-level logic sprinkled in between several consecutive SQL statements. This negates the option to use stored procedures since subsequent SQL statements depend on application logic that cannot be transferred into the database. I need the ability to rollback on errors (i.e. I need to use a transaction), but I also need to avoid race conditions.

Reading the MySQL documentation, START TRANSACTION will implicitly issue an UNLOCK TABLES statement; conversely, LOCK TABLES will implicitly COMMIT any active transaction. At this point it appears that I have to choose between transactions and locks, but I need the functionality of both.

Two Alike Conditions In Query?
Example. I have a table with information about payments (id, amount, pay_date, customer_id). Can I select two sums for two different date ranges, grouped by 'customer_id' (for each customer) in one query?

Left Join Conditions
Two tables.

table1, table2

Table 1 contains all unique items.
Table 2 contains x references to table 1, unique by customerId

I want to do a join onto table2 where table1.id = table2.table1Id AND table2.customerId = the user's ID

I can't quite figure out how to work in the idea of an AND into my left join. Unless both those conditions are two, I don't want any data from table2.

Only solution I can think of so far is to just left join on the id's, but select the customerId from table2, and as I loop through, check to see if it's supplied and the right id, and keep track of duplicate items from multiple customers myself.

Suggestions?
