MYSQL :: Update Table A For Every Instance In Table B

Temporary Table Accessable Only In Instance Of Procedure
If I have a procedure that will be run simultaneously by several people
which requires the use of a temporary table is there a way for the table
to be accessible only in the instance in which the procedure is being
run so that multiple tables can have the same name but not have
collisions?

I would normally think to name the table with a random
string but apparently SQL rules do not allow dynamically generated table
names. The other thing I would try is to have a permanent memory table
with the structure I need, with an additional column that would be
populated with a random number that indicates which batch is being
processed, with the contents being deleted right before the procedure
ends.

I don't know what kind of impact that would have on the server,
and am hesitant to try as my test environment has nowhere near the
capacity of the production environment, in just about every way possible.

Update Column In Table A With The Count Of Another Table
Having my SQL-background in Oracle I'm looking for the MySQL equivalent for:

update tableA
set column1=(select count(*) from tableB where tableA.key= tableB.key)

cannot find anything similar in the manual, but probably overlooking
something.

Update One Table Value With Values From Another Table
I am trying to update one table value with values from another table, and I cannot get it to work. What am I doing wrong?

This is my SQL-command:
UPDATE tabel1 SET tabel1.name=tabel2.name WHERE tabel1.ID=tabel2.ID

Update Table With Info In Other Table
i have a case like this:

table table1 (key, accumulator)

table table2 (key, counter)

i want to, for each table1.key = table2.key, update accumulator with the info in counter, something like this:

update table1 set accumulator=accumulator+table2.counter where (? counter is the value related with the same key as the one in table1)

how do you write a sentence like this one?

Update Table From Temporary Table
I have an import process that creates a temporary table and then dumps a large amount of records into it. I need to update an existing table against this temporary table. So where the record exists I either want to update or replace (probably based on parameter but can be a separate query for each) it in the live table, and if it does not exist i want to add it.

The temporary table can contain a large number of records (100000-200000). How can I create a fast and efficient process for doing this? Is there a query I could write to do this or would I have to do this through through code (i'm working in a java environment). I think a query would be faster than processing that many records via jdbc.

Table Design Question? House Table, Owner Table, Code Violations Table - Best Way?
Given the tables:

HOUSE
house_ID
address

OWNER
owner_ID
name
telephone...

HOUSE_OWNER_JOIN
?

CODE_VIOLATION_HISTORY
house_ID
violation_ID
violationStatement
...

My goal is to be able to track code violations of the house PER owner.

For example, I need to display a page that shows the current house with it's coe violations and a link to show the HOUSE's history of violation regardless of owner, Like:

House 1009283
Address
Past history (link to the following)

House History
2001-01-04 Owner: John Smith Code Violation: Gutter issue
1999-06-01 Owner: John Smith Code Violation: Faulty Steps
1998-03-02 Owner: Sam Spade Code Violation: Driveway carcks
1990-01-12 Owner: Keith Sledge Code Violation: Grass untidy

For the design of the HOUSE_OWNER_JOIN table, I thought of two ways I could go on this and this is where I need your help.

Option 1:
Have the HOUSE_OWNER_JOIN table keep dates so I can track the ownership changes that way:

HOUSE_OWNER_JOIN
houseID
ownerID
dateOwnershipBegan
dateOwnershipEnded

then I could look up all code violations by date and associate them with their rightful owner.

==================================================
Option 2:
Have the HOUSE_OWNER_JOIN table be the primary keeper of identity data by adding a new primary key and changing the CODE_VIOLATION_HISTORY table to reference that table by chaning the referencing key from house_ID to house_owner_ID:

HOUSE_OWNER_JOIN
house_owner_ID
houseID
ownerID
dateOwnershipBegan
dateOwnershipEnded

CODE_VIOLATION_HISTORY
house_owner_ID
violationStatement
...

Update Table With API
I'm trying to develope a getway between matlab and mysql. I would like to
write the result of matlab routine into mysql table without "UPDATE
.....SET..." statement, because I've have to write a different value for each
row and I have to write a lot of row. I would like to write table row by row
sequentially.

UPDATE Table SET
Does anyone know how to implement this into a php form CORRECTLY? I have all the proper syntax but then the server gives me a message that says the mysql version may not go along with the syntax. How do I work around this then? I need to update query strings and such and nothing will work.

Update From One Table To Another ????
I have two tables with linked fields, a one to many relationship. It is a item sold table to work order table where there are many items sold linked to a single workorder. I want to add up all the item taxes for the particluar workorder and instert it into the appropriate workorder. I have tried something like this:

update set workorder.tax (sum)woitem.tax where workorder.id=woitem.linkid

Can someone show me where I am going wrong?

Table Update
How do I relate such a way that I update a column of the main table, another secondary table's column related to the main table gets updated automatically?

UPDATE From One Table To Another
This should be so simple but I'm getting a very strange error??

I'm using MySQL version: 4.1.12-log

I've got an outdated country table that I'd like to update info from an ISO table. Pretty straight forward if you ask me.

Here's the query:
UPDATE country, isocountry SET country.un_numcode=isocountry.numcode
WHERE country.country_code=isocountry.iso;

I created a column called un_numcode and then I'd like to put the iso numcode info in my table where the country_code = iso code (same data, different field names in different tables).

It goes along really well for 38 rows out of 239 rows?? And then I start getting 127 in ALL the un_numcode fields even though that value does NOT exist in the country.numcode table!

Update Table
Im trying to update a table, but Im getting the following error...
Syntax error or access violation: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 5

Here's my code...

<cfquery>
UPDATE printers SET name= 
<cfif IsDefined("FORM.name") AND #FORM.name# NEQ "">
'#FORM.name#'
<cfelse>
NULL
</cfif>
WHERE printerid=#FORM.printerid#
</cfquery>

Update Table
What is the right syntax of UPDATE command, I want to use multiple (more than 5) WHERE clauses and update more than 2 fields.
UPDATE table SET UPDATE1 =â€™xyzâ€™ UPDATE2 = â€˜abcâ€™ WHERE 1=â€˜zxcâ€™ 2=â€™werâ€™ â€¦â€¦â€¦â€¦?

Update Table
I want to update a number in a column adding a 1 to the current number, however I don't want to select the table first.

Update Table
everytime it tried to update row in any table, it takes very longtime, it locks the table, then i run out of connections and mysql crashes.

2-table UPDATE
I am running the following query through PHP's mysql_query:

UPDATE hotel, hotel_brand
SET hotel.hotel_brand_id=0, hotel_brand.hotel_brand_parent_id=0
WHERE hotel.hotel_brand_id=6 AND hotel_brand.hotel_brand_parent_id=6

In actuality, it's two queries combined into 1. I am deleting a value that rows in these 2 tables reference, and want to set the values to 0.
Of course, the problem is the values aren't changing to 0.

Is splitting these up the best solution?

Update One Table
I have 2 tables one for the team standings one for the scores, this select statement will calculate win loss :

SELECT
SUM((homescore>awayscore and home=teamid)
OR (awayscore>homescore and away=teamid)
) as wins,
SUM((homescore>awayscore and away=teamid)
OR (awayscore>homescore and home=teamid)
) as losses
FROM scores, teams
order by teamID

UPDATE Table
Code:

UPDATE table SET field='select concat(field1,field2) from table'

This gives me a zero in my field
I can select concat separately without any problem

Using Import To Update Table
I'm working on a business directory site that I created using phpmydirectory. All of my data was imported into mysql from the admin area of my site.

My category table has ID, Title, Description, and Keywords fields. At the time that I imported my business listings, I left the Description and Keywords fields blank. I am now wanting to go in and add descriptions and keywords to each category. I would like to setup a simple spreadsheet and fill in the description and keywords for each category, and then use Import in PhpMyAdmin. Is this possible? If so, how would I set it up? Am I making sense? I really have no idea on how to use PhpMyAdmin. I can browse around and export when I need to, but I'm scared I'll screw something up if I try to update a table.

Update A Table Being Selected?
Is there a relatively easy way to fix this bad decision I made long ago? I created a table thusly:

CREATE TABLE `blah` (
`mod_date` date NOT NULL default &#55612;&#57200;-00-00',
`mod_time` time NOT NULL default ༼:00:00',
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
I added a new field to the table that looks like:

`modified` datetime NOT NULL default &#55612;&#57200;-00-00 00:00:00'
I thought I could update it with:

UPDATE blah
SET modified=(SELECT CONCAT(mod_date, ' ', mod_time) FROM contacts);
But a search in this forum showed that one can't UPDATE a table that is being SELECTed from. There was mention of a temp table (and perhaps JOIN(?)), but further searching has left me wanting.

UPDATE Based On Value In Another Table
How do I update a table to remove orphaned references to a second
table? I've deleted rows in the second table, which has a unique
auto_increment key. The first table now has references to keys that no
longer exist. I need to update the first table, setting the value to
NULL where the referenced key no longer exists. Something like:

UPDATE table1 SET table2ID = NULL WHERE table1.table2ID NOT FOUND IN
table2.ID;

The NOT FOUND IN isn't SQL, of course, but I'm not sure what should go
there.

Update Based On Other Table
I know this is how this query would be written in SQL but I think something isn't working correctly since this is mySQL.

SQL query:
UPDATE watches SET watches.totalhits = ( SELECT COUNT( id ) AS totalhits
FROM watchtracker
WHERE watches.id = watchtracker.watchid )

MySQL said:
#1064 - You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT COUNT(id) as totalhits
FROM watchtracker
WHERE watches

Update A Table With Values In Another
I have the following table

tableA
column_a
column_x
column_y
column_z

tableB
column_x
column_y
column_z

How do I update the rows of tableA that match rows of tableB (all rows
of tableB are unique)

What I want to acheive is a check against tableA.column_x with
tableB.column_x, if they match, then update the row in tableA.column_y
with the value of tableB.column_y and tableA.column_z with
tableB.column_z

Update Table Problems
I'm trying to update a table where specific values are in another table. Here is the update statement I am using:

UPDATE Route_Detail,Routes SET Route_Detail.Trip_Calc='S'
WHERE Routes.Route_ID = Route_Detail.Route_ID
AND Routes.Project_Code = 'OSUT'
AND DATE_FORMAT( Route_Detail.R_Date, '%m%Y' ) = 072006

This statement runs but does not update any rows.

This select statement returns 11 rows:
SELECT RDetail_ID
FROM Route_Detail
INNER JOIN Routes ON Routes.Route_ID = Route_Detail.Route_ID
WHERE Routes.Project_Code = 'OSUT'
AND DATE_FORMAT( Route_Detail.R_Date, '%m%Y' ) = 072006

How do I get the UPDATE statement to update those 11 rows.

I'm using MySQL 4.1.21-standard version.

Very Slow Table Update
I have two tables. One is really a subset of the other. However, they came in different data files and I would like to pull data from one and put it into the other. However, it is VERY slow!

Once the tables are setup I will only read from them and perform operations. I will never update or insert. However, I can't get things setup to that point. Code:

Update Table By ID Ranges
How do i use the UPDATE statement to update a range of Primary Key id
numbers. (let say 100 through 1000).

Example,

UPDATE testTable set testField='9999' WHERE
test_id in (100:1000);

Fields In Table Will Not Always Update,
I'm using C#, ASP.NET and MySQL, The language is no problem (not to much) but the rest well I wonder. I have a DB table that has 5 seperate fields. A main one that
is Integer and the rest are VarChar(50). each of the 4 others are identical in setup. I can change some records and others I can't.

ID int(10),
std varchr(50),
atd varchr(50),
dtd varchr(50),
ctd varchr(50)

I update say 'atd' with new data, Date, Time and a code of 15 letters/numbers.This one takes, I change to another record and try to update ctd and it shows like it takes but when I use the Command Line it shows no updates on ctd. this is random on this also.
If I change to another record it may all work or not. Any Ideas at all?

Update Fields In Table
I am trying to update multiple records,rows,fields in a table. Below is what I am placing in the sql field in phpmyadmin. It works with one update line but not more. What am I missing here?

UPDATE Products SET TitleTag='U.S. Air Force Retired Shop On-Line for Flags of the world - US, International Flags ' Where Product_ID=28;

UPDATE Products SET TitleTag='Vietnam Veterans of America Shop On-Line for Flags of the world - US, International Flags ' Where Product_ID=29;

Update Table Values
I have a csv.txt file with contacts and their information in it. Then I also have a table in mysql with the same contacts and their various information. I need to merge these to so that if a field value in the database is NULL the value that is in the csv.txt file is inserted into the database field.

I have been looking at the mySQL site on how to do this but have not been able to produce a working solution. Below is a more detailed example of what I am looking for. Code:

UPDATE Based On Value In Another Table

auto_increment key.

The first table now has references to keys that no
longer exist. I need to update the first table, setting the value to
NULL where the referenced key no longer exists. Something like:

UPDATE From A Linked Table
I wanna update the table COMPANY from a linked field. The following is not
accepted. Could anybody help me with what the command should be?
Thanks a lot.

UPDATE `COMPANY`
SET `COMPANY`.Region_ID =
(
SELECT `Area`.Region_ID
FROM `AREA`
WHERE `COMPANY`.Area_ID = `Area`.Area_ID
)

Multiple-table Update With Sum()
I have the quantities from different warehouses for each product in products_quantities, and the aggregate quantity for each product in products. I want to update products with the total from products_quantities. Why does this not work?

UPDATE products p, products_quantities pq
SET p.products_quantity = SUM(pq.quantity)
GROUP BY pq.products_id

I've tried every variation I can think of, but always get a syntax error near 'GROUP BY pq.products_id'. Can I not update one table with the sum of values from another table, in one query? I'm using 4.0.26.

Update Same Table With More Than One Record
I have a forum table which I need to perform the following update

1) I have an original message which I need to change its online status into DISABLE 'D' in my "status" field as follow single command:

UPDATE forum SET status = 'D' where message_id = 1 and parent_id is NULL;

*the parent_id field is NULL because it is a parent thread...

However, it has some child threads to this message...therefore I must force the all the child thread to change the status into 'D' also. So I did a second sql query as follow:

UPDATE forum SET status = 'D' where parent_id = 1;

*parent_id = 1 means it points to the parent message_id = 1

My question is

DOES anyone know a good sql query that will combine these two queries into ONE single query?

Update Linked Table
ODBC --update on a linked table 'tblname' failed.
[Microsoft][ODBC Driver Manager] SQL data type out of range (#0)
I get this message whenever I try and update or change anything. I can't even open a table, delete a number 4, replace it with 4, and it still fails.

What causes this? I have a primary in every table (though they aren't called primary) and a timestamp in each table.

Update Table With Java
im trying to update my table bunt

int test=5;
String update="Update bunt SET buntnr='test' Where bunt_ID ='ver.bunt_ID'";

wich results in this error

Data truncation: Out of range value adjusted for column 'buntnr' at row 1

If i use this, changing variables to Ãnt it works fine!
String update="Update bunt SET buntnr=5 Where bunt_ID =1";

Update Records In Table
i have installed a mysql server, and i have a problem with import record in database.
the origine is a file txt or csv, the destination database contain also other records, and i must update the records into database

Multiple-table UPDATE.
I'm trying to update multiple-tables at the same time but I read somewhere that you could do it if you had mysql version 4.0.4. But currently, I have version 4.0.0 and I want to know how to do it with this version

Insert And Update Entire Table
My website will modify records on my products table. But I need to occasionally update their qty and their prices without losing any changes already made by other users online (like qty sold).

I'm able to do that now. It works really well:

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.

You Can't Specify Target Table '' For Update In FROM Clause
I have problem deleting rows from table with subquery referring to the same table. I store tree structure in the table (there is ParentID field for each row that specifies primary key of the parent row). I'm trying to delete all children of the given row which doesn't have their own children. I can't do this from the script by iterating through all rows because there could be thousands of such records.

I thought that the following query will do that:

DELETE P FROM `tree` AS P WHERE P.`ParentID` = @parent AND NOT EXISTS (SELECT * FROM `tree` AS C WHERE C.`ParentID` = P.`ID`)

But this doesn't work, throwing error:

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

How can I make this work?

Update Comment In Field In Table?
Create table images (
UserID Int UNSIGNED NOT NULL,
ImageID Int UNSIGNED NOT NULL AUTO_INCREMENT,
Name Char(50),
Description Text,
DateModified Datetime,
Active Bool,
Private Bool COMMENT 'This field is used to denote an image that should not be available in the global search engine for photogap',
Type Smallint COMMENT '0 = jpg 1 = gif 2 = bmp 3 = ico 4 = png 5 = psd 6 = flash Others can be added if needed.',
Primary Key (UserID,ImageID)) ENGINE = MyISAM
ROW_FORMAT = Default;

And say I wanted to update the COMMENT on the field 'Type' how would I do it?

Right now that field says COMMENT '0 = jpg 1 = gif 2 = bmp 3 = ico 4 = png 5 = psd 6 = flash Others can be added if needed.'

But I need to change this as things have been reworked and added and these numbers do not match up anymore.

Update One Field With More Fields From Another Table
I have a select count() that seams be ignoring one clause. Data:

Table:
ID CA-Char CB-Int
1 dsfsd 6
2 dsfsd 0
3 dsfsd 1
4 sdrtt 1

SQL is:
"SELECT count(id) FROM Table WHERE CA-Char = 'dsfsd' AND CB-Int > 0"
Returns 3 - Should be 2

Update One Table Based On Count From Another
I heve two tables Publishers and Books.

Publishers has:
PublisherID
PublisherName
BookCount

Books has:
BookID
PublisherID
BookName.

I want a query that will update the BookCount field for every Publisher taking the number of books each one of them has in the Books table.

What would be the mySQL Update query for this?

Hope I have given enough information. I will gladly provide more.

Update Query Where Values Will Come From Other Table
I'm creating an update query which the value will come from another table.

I have here my current query which unfortunately makes the system hangs. Probably because of the query itself is not properly coded.

update boxes b inner join messages m
on b.ctnnumber = m.ctnno
set b.consigneerecv = m.CName,
b.consigneerecvdate = m.DateRcv,
b.phrecventered = "Y",
b.PhilStatus = "delivered",
b.prevreleasestatus = b.releasestatus,
b.releasestatus = "delivered",
b.PhilStatusDate = m.smsrecvdate,
b.phdelprice = "0.00",
b.phdelamt = "0.00",
b.recvrelation = m.Relation,
b.APRecventered = m.smsRecvDate
where b.consigneerecv = ''
or b.consigneerecv = 'NA'
or b.consigneerecv is null;

I'm thinking revising it so that it will not cause the system to hang but I don't know how. Guys please help me with this one. I also have this another idea which probably will not work. My idea was something like this:

Update table1 set table1.column1 = (select table2.column1 where table2.column1 = table1.column1),
table1.column2 = (select table2.column2 where table2.column1 = table1.column1), .....

MySQL 4.1 Script Update Table
We have a MySQL 4.1 Database running on a RedHat Linux box. Every so often (nightly?), I want to run a job against the tables to select the records from "X" Days ago and update a flag in that table. First, can this be accomplished? And second, can anyone point me in the right direction?

Update A Table In A Timestamp Field
I would like to update "field A" in a table in which "field B" is a timestamp. I would like to update all fields whose date is less than a given date. This is the command I was using to no avail:

UPDATE my_table SET
Field_A=50,
WHERE filed_B <= '2005-05-12 15:08:44';

MySQL is returning the following error:

#1064 - You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE filed_B <= '2005-05-12 15:08:44'' at line 3

My Host is using MySQL 4.0.25. Can anyone point me in the right direction? What am I doing wrong?
