MYSQL :: Update A Table With Data From Another Table

Update Whole Table With Unique Data Per Row
This is my first post and I am fairly new to MySQL and PHP. I need to update an entire column of data with a column of data from another table. Each row is a price attached to a specific product.

When I do an Update/Select, I get an error saying more than one row is being returned.

Is there a way to do this using MYSQL alone, or do I need to use PHP and and a loop with individual inserts per row?

Update Statement :: Data From One Table To Other
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.

UPDATE Query With Getting Data From Another Table?
is it possible to use UPDATE command with getting data from another table.

I have two tables:
base1.table1 with COUNTRY_NAME, ID_NUMBER
base2.table2 with COUNTRY_NAME, LINK

I need to get value of ID_NUMBER from base1.table1 (about 300 rows) and UPDATE base2.table2. So, I need to copy values of ID_NUMBER to LINK.

I wonder is it possible to do just with one query or I will need to write PHP parser to do this job?

Update One Table With Data From Another That Has Multiple Returns
I have a query that works but it takes extraordinary amounts of time to run and I'm sure there's got to be a better way. I haven't touched sql in many years and I just can't remember the proper way to do this.

Table 1 has a column that I need to fill from table 2. Table 2 has multiples of the requested data. There are about 303 records in table2 that meet the >0 criteria but only 44 distinct values that I need to retrieve. col1 in both tables is the matching index.

What I have so far is:

update table1 a set a.col2 = (select b.col2 from table2 b where a.col1=b.col1 and b.col2>0 group by b.col1)

I also tried limit 1 instead of group by but there was no difference in execution time (which is about 5 updates in 10 minutes!)

Update Column Data Based On Another Table
I've got 2 tables: 'city' that list over 2000000 rows and 'profile' where each row are associated to a city.

What I want to do is to update cities popularities based on profile without having to scan the hole 2000000 rows of 'city'.

So is it possible to make those 2 query in one so I do not need to do a php loop:

SELECT city, COUNT(city) FROM profile GROUP BY city;

then

UPDATE city SET popularity = COUNT(city) WHERE city.city_id = profile.city

Import Update Of Csv/excel Data Into MySQL Table

Data Insertion/Update Form Different Tables Into On Table
I have 3 tables say Employees, Benefits, Employee_Benefit_Mapping. These tables are something like this:

Employee:
========
Employee_Id
Name
Dept_Id
.
.

Benefits:
=========
Benefit_Id
Benefit Name
.
.

Employee_Benefit_Mapping:
=========================
Mapping_Id
Employee_Id
Benefit_Id

Its a many to many relation. Hence the mapping table.

Now the situation and question is:
====================================
Every employee "In a certain Dept" is eligible for some benefits by default. How can add these records with one (or minimum) insert statement(s) rather than going employee by employee?

Insert into Employee_Benefit_Mapping ((Select Employee_Id from Employee where Dept_Id = xx), (Select Benefits_Id from Benefits where Benefit_Id in(xx, yy)))

Will this work to insert all the data into the mapping table?

Select Count Of Data Appearing In One Table From Another Table
I have three tables:

t_Products (id, name)
t_Shop (id, location, name)
t_Carries (product, shop)

If Shop carries a product, there will be a value pair in t_Carries but otherwise no record is listed.

Is it therefore possible to return a list in MySQL showing something like this

shop.Id, product.Id, count(or something)
1 1 0
1 2 1
1 3 1
1 4 0

Or must I use two query and programmatically generate the list?

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

Extracting Data From Large SINGLE-table Database To MULT-table Relational Database
I have a very large single-table database of articles that I want to convert to a multi-table, relational database.

The existing single-table database contains fields for article author, article source, and article category, where several 'author', 'source', and 'category' IDs repeat dozens of times for hundreds of different articles.

I want to create seperate tables for author, source, and category and populate the new tables by extracting data from the original single-table database by unique ID field.

I figured out how to use INSERT and SELECT to pull data in new tables, but can't figure out how to pull only a single instance of a unique author, source, and category to create master reference tables for author/source/category.

Update Table From Another Table
I have 2 tables: country and ticket

country table contains countryId and countries

ticket table contains many fields, and a country field

the country table is new and consists of all countries to be used in a drop down on the ui, that is joined with the ticket table to display the correct country based on the id.

that being said.. the current ticket table also contains a country field which will be eliminated in the future. what I want to do is update the ticket table by finding the closest match to ticket.country in the countries.country table and then update the ticket.countryId to the countries.countryId.

This is what i have been doing country by country:

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 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!
