MYSQL :: Update One Table Value With Values From Another Table

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 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 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), .....

INSERTing Into A Table, With Values From Another Table
I'm programming a shopping cart application, where the products are categorized into different lines. I have a table that defines the different product lines, and now want to populate the product table.

However, the text file with the products in it, which I will use to populate the products table, uses the line NAME for each product, when I wish to use the line ID instead. To get the line ID, I would need to get the value from the line table.

My question is: is it possible to populate the products table with data from the products text file, as well as a column from the lines table?

That is, the INSERT (or LOAD DATA) statement will insert column values from the text file, but the line id from the lines table instead of the line name found in the file (WHERE line name = line name in the lines table).

I'm still not sure whether to use an INSERT, and write PHP code to go through the text file, or to use LOAD DATA for this task, because I don't know which statement would support what I'm looking for.

Insert Table Values From Another Table
I have two tables: Users and metadata

Users:
id
userid
username

Metadata:
id
userid
value

I would like to extract a list of the userid's from the users table and enter them into the metadata table, with an additional value.

Example:
I want to take all of the userid's from the User table and insert them into the Metadata table, and make the value="one" for each entry into the Metadata table.

Inserting Values From 1 Table Into Another Table
I have 2 tables: A and B
Table A contains fields u, x and y
Table B contains fields u and z

Table A has all possible variations of u.
Table B has some of the varaiations of u in it.

My problem is that I'm trying to insert the z-values from Table B into Table A's y field and link them up based on the u-values.

I'm running into problems like truncating at row 0.

I've tried the following queries:

update TableA set y =(select TableB.z from TableB where TableA.u=TableB.u)

update TableA,TableB set TableA.y =(select TableB.z from TableB where TableA.u=TableB.u)

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 Table A For Every Instance In Table B
I have learned how to select records from two tables but now, I need to update every record in table A based on keys found in table B.

I have a KEY which I can match to records in table B and table B has a field which I can match to records in table A. I need to update table A and possibly table B.

How do I go about this?

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
...

Add Values To Table
I have a table tblMailingList. It has 3 columns; Name, EmailAdd, AutoID.

I am using
mysql> INSERT INTO pet
-> VALUES ('name1','u@me.com');

but I am unsure as to what to do for the AutoID field. If I use the example given, the error message says that the number of fields is different.
How do I get this info into my table?

INSERT Values From One Table To Another
In table A i have a.id and name and in table B, i have b.id, a.id(FK) and owns.

Table A
--------------
a.id | name |
--------------
12 | James |
13 | Paul |
14 | Tom |
15 | Andy |

Table B
--------------

b.id | a.id | owns |
--------------------
1 | 12 | Car |
2 | 12 | Bike |
3 | 13 | PC |

Now what i want is to add two new names to table A which will be Tom and Andy and have the same data in table B for Tom and Andy with just different b.id (PK).

How can i insert this new data in table B using insert?

Edit Values In Table Through GUI
I wonder which GUI tool I can use if I want to edit some values in a table? I can't find it in Query Browser. Do I really need to execute SQL to make a simple change to a field?

Returning Values That Are In One Table, But Not In Another
I'm looking for a query to return values which occur in one table, but not in the other.

Say we have two tables (table_1, table_2) each with a column titled "appointments".

I want a list of results for appointments which are in table_1, but not in table_2

I have tried the following, but all I get is a huge list of duplicate appointments which occur in both tables:

SELECT table_1.appointments
FROM table_1, table_2
WHERE table_1.appointments<>table_2.appointments;

I've also tried 'NOT IN' for this but the result was just the same.

Get The 3 Highest Values From A Table
My problem is to get the 3 highest values from a table

Editing Values In A Table
I just moved from SQL Server to MySQL and in the Enterprise Manager in SQL Server I could query the entire table and then modify the values with the table without writing an UPDATE statement.
I cannot do that in one of my tables because the EDIT at the bottom is greyed out. There are other tables where I can make a modification to any value I want within the table.

Ignoring Rows According To Values In Another Table
I have the following query:

Inserting Values Into A Mapping Table
I am using a mapping table with two primary keys (ID1, ID2). When I try to insert data into this table I get the following error:
Quote:

Violation of PRIMARY KEY constraint 'PK_myTable'. Cannot insert duplicate key in object 'dbo.myTable'. The statement has been terminated.

I am able however to insert values if I do it directly into my table.
Here is an excerpt of my

comm = New SqlCommand( _
"INSERT INTO myTable (ID1, ID2) " & _
"VALUES (@ID1, @ID2)", conn)
' Add command parameters
comm.Parameters.Add("@ID1", System.Data.SqlDbType.Int)
comm.Parameters("@ID1").Value = ID1List.SelectedItem.Value
comm.Parameters.Add("@ID2", System.Data.SqlDbType.Int)
comm.Parameters("@ID2").Value = ID2List.SelectedItem.Value

Generating A Table With Missing Values In SQL
I have the following table:

+------+------+------+-----------+
|ID |GROUP |CODE |ANSWER |
+------+------+------+-----------+
|1 |1 |001 |01-01-2003 |
|2 |1 |002 |Yes |
|3 |1 |003 |NA |
|4 |1 |004 |297797 |
|5 |1 |005 |0 |
|6 |2 |002 |Yes |
|7 |2 |004 |297852 |
|8 |2 |005 |1 |
+------+------+------+-----------+

This means that code 001 and 003 of group 2 are missing. Result of the
query should be:

+-------+-----------+-----------+-----------+-----------+--------+
|GROUP |ANSWER1 |ANSWER2 |ANSWER3 |ANSWER4 |ANSWER5 |
+-------+-----------+-----------+-----------+-----------+--------+
|1 |01-01-2003 |Yes |NA |297797 |0 |
|2 |NULL |Yes |NULL |297852 |1 |
+-------+-----------+-----------+-----------+-----------+--------+

The missing values should be replaced by a NULL value in my resultset.
Is this possible? I don't have any clue how my query should look like,
can anyone help me and show me a solution?

Eliminating Double Values From A Table
I need to consolidate data from many adress databases, which i allready sucessfully put into one table1. As Newbie i am reviing the Manuals and tutorials, but in 2 days i learned a lot about the powerfull command, but not how to solve the following question:

Is there a straight forward method to copy data from one table1 into the other table2, but not those rowse, which have same value in Fieldx.

All my Update and INSERT SELECT experiments somehow created more then less data in the target table.

Insert Values Only If They Do Not Already Exist In Table
I want to insert some values from one table (A) into another table (b). However there are some values in table A which exist two times in table A. I only want to insert values one time. So If a certain field value also exist in some other row (same fieldname) then I don't want to insert it twice. It doesn't matter which of the two rows will be inserted.

Can this be done with MySQL? Maybe with some Control Flow Functions?

Updating A Table To Increment Values
Question, if I want to update all values in a certain column to increment by one, what statement could I use? In quasi-MySQL, this is my pseudocode:

UPDATE table SET fields=[previous_val+1] where [previous_val]>[my_val]

Or do I HAVE to run a SELECT query, increment the value, and THEN Update it?

I was just thinking there'd be an easier way.

Accepting Values As NULL When Not In Another Table
Is it possible to perform a SELECT query on multiple tables and simply accept one of the values as NULL if not in another table rather than the whole query failing?

For instance, if "rec_id" exists in "table_1" for certain but it is uncertain if it exists in "table_2", is it possible to return the query with a variable assignment stating whether "rec_id" was or wasn't found in "table_2"?

I am hoping I can do this without a LEFT OUTER JOIN as the query is fairly complex and involves five different tables. Whenever results are fetched I simply need to know if rec_id is or isn't in table_2 if it is found in table_1.

As there are frequently over 10,000 result rows returned it wouldn't be sound to put this into a seperate loop that queries with each rec_id to see if it is in table_2.

I have tried "SELECT table_1.rec_id, table_2.rec_id FROM table_1, table_2 WHERE table_2.rec_id=table_1.rec_id OR table_2.rec_id IS NULL" but this returns no records.

An Enum Field Using Values From Another Table
The first table, called genus, contains several fields, the important one in genus is name, and there are others about the individual plant types.

The second table 'plants' needs one field for the genus name, so that I can link tables on this. If there a way to make a foreign key from the genus table into an enum field on the second? My idea is that then, with phpmyadmin or similar I can just select the genus name from a list when entering new plant data.

Renumber Mysql Table Values
There are 100000 rows in a table, I need to renumber them from
1,3,6,8,11,14,21,55,888,1000,9999...99999
to
1,2,3,4,5,6,7,8,9,10,11,12,13,14...
etc
I also need to update an associated table, so its going to need to lock the tables, find the lowest available index in table1, then update table1 index, and then update table2 to use the same index as well, then unlock tables

What would be the procedure to do that?

Returning All Unique Values From A Table Field
I wrote a select that works fine but I am looking at it and thinking that the query might require mysql to scan EVERY row before giving me my answer.

Lets pretend I have a table with fruits and want to return all the available colors of those fruits that I currently have in the database.

Is this an efficient or horribly inefficient statement?

"select color from fruits group by color"

It seems to return what I want:

fruits:
------
blue
green
yellow
...

I am just wondering if it goes through EVERY row and groups them?
If I have the table indexed by color am I allright?

Replace Some Username Values With The Users ID In A Different Table
I really can't figure this out. I want to replace some username values with the users ID in a different table.

The tables are

pictures
user (Example FRED)
picture (Example pic.gif)

users
id (Example 5233)
user (Example FRED)

What I want to do is replace the user column in pictures with the correct id from the users table

So in the pictures table, it would no longer be FRED it would be 5233

Is there a query I can run to do this?

I'd really appreciate some feedback

Query To Insert 2 Foreign Key Values In Table
I want to insert 2 foreign key values along with some other value into table ....

INSERT INTO Table (vars) VALUES(vals)
I am trying to use the following command:
INSERT INTO sr_main (originator,symreq) VALUES (A.Person,269);

Whenever I enter the command above I get the following error:
ERROR 1054 (42S22): Unknown column 'A.Person' in 'field list'

I am confused because the error refers to my _value_ 'A.Person' as a column!? Do string values need to be surrounded with quote marks of some type? I have already tried the obvious (to me) quote markers, e.g. ", '

The data is accepted if I use this command:
INSERT INTO sr_main (originator) VALUES (269);

I actually have a lot more fields and values than shown, and ideally would like to use the command type:

INSERT INTO tablename (field1,field2,field3) VALUES (1,2,3)

Code:

Counting Occurrences Of Values In Table Column.
I have two tables;

Table 1;

Agent_ID UserID First_Name Last_Name

1ShadShad Mortazavi
2Harry Harry Potter
Table 2;

Recording_IDAgent_ID Status GSM_File etc
11 000001.gsm
21 0 00002.gsm
32 100003.gsm
41 200004.gsm
51 100005.gsm
61 200006.gsm
72 100007.gsm

Status 0 = Red, 1 = Yellow and 2 = Green

I would like a query that returns the number of occurrences of Red, Yellow, Green against each agent

so the data returned would look something like this;

NameREDYellow Green
Shad Mortazavi 2 0 2
Harry Potter 0 2 0

I'm using MySQL version 3.23.58

I can do this programmatically in Perl with several query's; but this is CPU intensive. If I could get this in one query I it would save time.

Selecting Unique Values From A Table (NOT DISTINCT!)
Lets say we have a table that has the field photo_id and has values of it many times. For example 245 can exist any number of times (1, 5, 8, e.t.c.).

I want to select the values that exist in the table ONLY ONCE. Please note that i dont want to select each value once (using DISTINCT), that would return all the values that exist in the table.

For example lets say the table has the following values:

245
563
776
224
563
563
776
776
776
776

The query i want to make should return only the values 245 and 224 as 563 and 776 exist many times in that table.

Date/Time As A Default Values For A Table Column
I am new to mySQL, so this question might be simple.I want to add a default value to a column that is the current date/time. I am using the mySQL Administrator and will not allow me to use a function like CURRENT_TIMESTAMP() or NOW() as a default value. I used to do this with other databases (I always add a column to all of my tables called InsertDateTime and UpdateDateTime. It helps to track down data entry problems)

Updating Column With Sumned Values For Each Record In Table
I have most of the query formulated, but am stuck on the portion where I need to specify which records to update. I want to update all the records in the table. How can I specify the request_id to be the same in both the select and update statement?

Here's the query I'm working on:

Code:

update enhancementrequests2 set
hardBenefitEffortSavings = (SELECT hardBenefitEffortSavings + hardBenefitLaborSavings + hardBenefitHardwareSoftwareSavings
+ hardBenefitOtherSavings AS hbTotal
FROM enhancementrequests where request_id = 1), hardBenefitLaborSavings = NULL, hardBenefitHardwareSoftwareSavings = NULL,
hardBenefitOtherSavings = NULL
where request_id = 1

In my example I have specified that request_id = 1, but I want request_id to match each row of the table in turn. I hope that makes sense.

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...

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€¦?

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 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
