MYSQL :: Copy Of An Existing Table

Table Joins On Existing/Non-Existing Data
I have a question that involves a joining tables on potentially non-existing data, but we will know the expected values whether they exist or not.

Say we're keeping statistics on any given number of sports for attendances over weekly time periods. There's two tables to hold data.

------------------------------
TABLE: StatisticTypes
id
name
------------------------------
TABLE: Statistics
id
statisticTypeId
value
date
------------------------------

Then, say, we have three entries in the StatisticTypes table for types of sports we're keeping data on...

Copying Column Names And Properties From An Existing Table To A New Table?
I've got a table with 42 columns, set to different types (string, datetime, date, integer). It has 8 million rows. I want to make a new table with the exact same columns, but with no data in it. Is there an easy way to do this without re-defining every column?

How To Add A New Row To An Existing Table?
I am able to create database, tables, inserting values, and so forth. My question is this:

Let's say I have a table on the list of items I owned, and some time later, I need to add a new item between after row 12 and before 13. How do I do that? I did look at MySQL 5.0 Manual and didn't find anything similar to what I wanted to do.

Foreign Key To Existing Table?
Is it possible to add a foreign key to a table that already exists? Or do I have to drop the table and recreate it?

Insert Row Into Existing Table
I have a table with rougly 70 threads, I now need to go back and insert a couple new entries into my table, but they cant go at the end, they need to go in the middle, say like ID 40,41,and 42. How do I do this?

Assigning Userids To Existing Table
I have a table of existing users in a database. I want to add a "userid" column to the database that automatically assigns an ID to each user when new accounts are added to the system. I know I would do something like this if I had the brains to have added the column at the time of creating the table:

ALTER TABLE writers ADD (
userid int PRIMARY KEY auto_increment
);

However, the table is now already active with users, and I want userids assigned to existing accounts on the system.

Import Data Via Ssh Into An Existing Table
I want to import data from several .sql files into an existing database, into one table.

I tried using the following command:
mysql -e [sqlfile] [db_name]

But the problem was when I imported the next file, it would overwrite the previous imported data.

Could anyone let me know how to do this correctly, please?

Add Multiple Rows To An Existing Table?
I have a table named manufacturers, it has one row in right now. I want to upload all of my manufacturers into the table. Is there a way to add multiple rows to the table at the same time? If not, what is a quick way to get about 1,000 manufacturers uploaded into a table?

Append Existing Data In A Table
I am working on an existing osCommerce store. There are over 200 products, each of which needs the associated image file name changed.

Rather than do this manually (any number of ways), I am unsure if there is a query I can run to save me lots of aggravation. What I would like to do is update whatever is in the field and change it to add the same 5 characters:

The Table is Products
The Field is products_image

Examples of existing data in this field are:

abcdef.jpg
ght.jpg
fire_777.jpg
oops.gif (the replacement image is a jpg)

The result I seek is:

abcdef_th.jpg
ght_th.jpg
fire_777_th.jpg
oops._th.jpg

Logic tells me to start at the end of the data, remove the last 4 characters (.jpg) and append 5, in this case: _th.jpg Could someone please give me a hand with this? I have spent many days redoing the image files and they are nearly ready to go into a live store.

How To Add A Auto_increment Field To An Existing Table
I want to add a field called "id" starting from 1 and auto increment, but it seems that mysql doesn't allow me to do the following.

alter table existing_table add id INT AUTO_increment;

Message: Incorrect table definition; there can be only one auto column and it must be defined as a key. But I don't have a key or auto column in the existing_table.

Adding A Foreign Key Into An Existing Table
May I know how should I do that?

The SQL statement should be:

CREATE TABLE USER_SYSTEM_SECURITY (
USERID VARCHAR(32),
HOSTID VARCHAR(32),
HOME_DIRECTORY VARCHAR(32) NOT NULL,
ACCESS_RIGHTS INT(3) NOT NULL,
PASSWORD_EXPIRY_DATE DATE,
ROLES VARCHAR(32) NOT NULL,
PRIMARY KEY (USERID, HOSTID),
FOREIGN KEY (USERID) REFERENCES MEMBER (USERID) ON DELETE CASCADE,
FOREIGN KEY (HOSTID) REFERENCES SYSTEM (HOSTID) ON DELETE CASCADE);

But I forgot to add in the last row during the table creation.

Search Table Column For Existing Value
I would like to search a table's column so that I can match an entered email address against the data in that column. I'm writing an aplication for an event and I don't want duplicate email addresses in the table. I'm using PHP4.

Auto Increment Existing Table
I have an existing table with many rows of data. I want to add auto increment to it so I do not have to manually asign each row a unique record number.

How To Import Data Into Existing Rows Of A Table?
I have moved 665 records off of Filemaker into mysql-4.0.18. I had a
great deal of trouble exporting a text field, possibly because it had
control characters that interferred with my field delimiter (also it
was from a Mac, and I'm new at this.)

So I have a table called invoices and another table called tasks, that
has only an invoice number and the work billed on that invoice number.
To see the work billed along with the other invoice data I have to do
a join, and this works but is clumsy for me. Since tasks.work is a
text field of 'infinite' variety I don't see the sense of keeping it
in a separate table like I would with clients' info; it belongs *in*
the invoice table, not just with it.

Is it possible to import this text data into a field in the invoice
table? I've messed around with this but it always appends the data as
new records. Perhaps I was doing an insert back then. Is the answer
something like 'load data infile 'workdone.csv' into invoices
(workdone);'

The invoices table was filled in a certain order (by invoice number)
and the workdone.csv was exported in the same order, so each invoice
row should get its correct text.

Is this a good thing, or am I thinking too 'flat-file-ish'?

Inserting 100 Rows Of Data Into An Existing Table
I want to import 100 rows of data from an Excel spreadsheet into an existing MySQL table. Both the spreadsheet table, and the MySQL table have the same exact format & headers.

In MySQl Query Browser, I can locate only the Edit function, which seems to only allow me to type in the data line by line. Can I import the data in MySQL Query Browser, or do I need another product? And if I can import, how do I do this?

Modifying Primary Key And Auto_increment In Pre-existing Table
Given the tables defined below, is there a sql statement that could make num_1 an auto_increment field without rebuilding the table (nevermind any potential numbering conflicts)? I don't see anything in the alter table documentation that will produce this effect.

Also, say I wanted to change the primary key of test_1 (e.g. primary key(num_1,num_2)). I think because num_1 is a foreign key for the table test_2 MySQL grumbles about changing the primary key, in addition to dissalowing the drop and redefinition of the primary key.

Could anyone tell me how to easily handle these situations? This is a simplified example of my actual situaion, but if it can be solved here then I think I would be OK. Code:

Import Additional Field Data To Existing Table
I've got my data all set-up in a mysql table and all functioning well.

We have decided that we need some additional bits of data for each record and we have that data in a csv file. We've created the fields in the mysql table.

In the csv file, I have the userid (to match that in the current sql table) and the additional data with the column names in the csv file matching exactly the new fields in the sql table.

The additional fields in the original sql table are empty, so we can just simply write-over these fields with the data from the csv file.

But...we are having problems with the import using the MySql administration tool on our server.

If I select a csv file upload, I get a number of fields is not same error
If I use csv load data upload, it just overwrites the first few lines of current data and doesn't put the new data in the correct fields.

Can anybody help, please? If csv load data is the correct format to use, what do I put in the import tool for these variables (given that I have a standard csv file that has been created using excel)

Replace table data with file (yes/no default is no)
Ignore duplicate rows (yes/no - default is no)
Fields terminated by(default is
Fields enclosed by(default is ")
Fields escaped by(default is )
Lines terminated by(default is auto)
Column names (default is blank)
Use LOCAL keyword (yes/no - default is yes)

How Do You Discern The Type Of An Existing Mysql Table Column?
I have a program that needs to be able to know whether a MySQL column is a number type or other. Is there a function that does this, or can anyone else suggest a way of discerning this reliably using SQL statements?

How To Copy Row(s) Into Same Table
Is there some easy way to copy row(s) from/to same Table?

MySQL HELP says (in 13.1.4.1 INSERT ... SELECT Syntax): "Currently, you cannot insert into a table and select from the same table in a subquery."

Copy Table
I have a table which I have added a column to, I want to copy the value of the first column to the last column for all rows. Is there an SQL query to do this or should I use perl DBI?

Copy Field To Another Table
I have 2 tables and would like to populate field2 in table 2 with the user field from table1. All i can find is examples of UPDATE for moving data within the same table. How do I UPDATE field2 with data from Table 1?

Copy/move Whole Table
I'm doing a conversion on a customer database and I'd like to take this chance to a lil learning

I have v4_customer:
v4_id | login | points

and v5_customer:
v5_id | login

I want to move it to customer_conversion:
v5_id | login | points

Is there a way to do a table wide join (or equivelant) on the field login and move all of the info to customer_conersion? The table is about 15,000 records. It will only be run once or twice on a development machine, but I figure if there's a better way to do it, why not learn. Is there a better way than to loop through each row?

How To Copy Records In One Table?
does anybody know how to copy a record within one
table? I am looking for some simple method similair to
INSERT INTO orders SELECT * FROM orders WHERE
Order_ID=256; Actually, this method does not work and
I can not believe that MySQL does not offer some
simple method how to do it. Keep in mind that I have a
60-field table. So, naming all fields is a pretty
tedius task.

Copy DATETIME From One Table To Another
I'm trying to copy a DATETIME field from one table to another using an INSERT statement like this:

INSERT INTO table2 (value1, date1)
SELECT (value1, date1)
FROM table2;

MySQL gives me this error:

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 ' date1) FROM table2'

Date1 is a DATETIME field in both tables. I'm not trying to insert the current date or a timestamp. Date1 needs to move unchanged.

Copy Table To Another Database
I have two tables and I'd like to copy some contents of table 1 to a specific field table 2. Their (the tables) purposes are the same, but the structure is different. There are some fields present only in table 1 and others only in table 2.

Is this possible?

Copy Table From One Database To Another
i have two databases in mysql server, How i can copy one table from one database to the other one?

Copy Large Table?
I want to copy just part of a very large table from one database to another database. The table contains several million of rows.

So far the only thing I can think of is using MySql dump. However, that will give me all the rows in that table, right? But I just want to grab 1000 rows to do testing.

Copy Data From One Table To Another
I want to retrieve all records from one table and insert them into another table. Can this be done in one statement?

Copy Record From One Table To Another?
I've successfully installed and created a database for my company's web portal, which contains a Staff Directory. The thing is, I need a second data base with for the former staff. Is there a way to write a SQL statement that will delete the record from the current employee table, and add it to the former employee table?

Copy And Rename Table
I have a table that I'm using as the 'default' table to be used in a game creation

When a new game is created, I'd like to be able to copy the table and rename it, something like game_map_29. The 29 will be the variable generated for the next game. The new game_map table will than be modified as the game progresses.

Can someone maybe give an example on copying and renaming table?

SQL-Statement To Copy A Table Into A New One
i want to copy many records from one table into a new one. I found only the statement to export to an file and reimport them, but i don't like this version.

Example:

select * from abc where Status = "C" into outfile "abc-c";
truncate table abc-c;
load data infile "abc-c" into abc-c;

Copy Table With Autoincrement
I have tried a lot to copy a table with php, but I can't:

I tried first:
CREATE TABLE copy SELECT * FROM table

but it doesn't copy autoincrement or primary key. Deleting the autoincrement column, and then assigning it, does however makes an auto_increment column, but the values doesn't correspond with the original, because some posts where deleted there, and then the auto_increment values are higher.

Then I tried to assign those two values later, by first truncating.
CREATE TABLE copy SELECT * FROM table";
$sql2="TRUNCATE TABLE copy";
$sql3="INSERT INTO copy SELECT * FROM table";
$sql4="ALTER TABLE copy ADD PRIMARY KEY (id)";
$sql5="ALTER TABLE copy CHANGE `id` `id` INT( 11 ) NOT NULL PRIMARY KEY AUTO_INCREMENT";
$sql6="ALTER TABLE copy AUTO_INCREMENT=$maxid

but that doesn't work either. Isn't there a simple way to copy a table including the primary key and the autoincrement with php?

Copy Column From One Table To Another
I have managed to get:

update table_A , table_B set table_B.col_1 = table_A.col_1 where table_B.col_# = table_A.col_#

to work on PHPMyAdmin 2.6.1-pl3 with MYSQL 4.0.16

but it will not work on PHPMyAdmin 2.6.0-pl3 with MYSQL 3.23.58;

Copy A Really Huge Table
I have a really huge table that I need to copy however using the Export function in MySqlAdmin does not work because it "times out". All I really need to do is generate an SQL script that will, drop the table if it exists, create the table and its structure, and then insert the data line by line.

Usually when you perform a command in MySqlAdmin through Internet Explorer the MySQL command line is displayed with the results. However, this does not happen when you export.

Anyone know how to do this from the MySQL command line?

In a nutshell: I need to backup a table to an SQL script file.

Searching A Copy Of A Table
Code:

CREATE TABLE `submitted_answers` (
`id` int(11) unsigned NOT NULL auto_increment,
`survey_id` int(11) unsigned NOT NULL default '0',
`question_id` int(11) unsigned NOT NULL default '0',
`answer_id` int(11) unsigned NOT NULL default '0',
`other_value` text,
`user_id` int(11) unsigned NOT NULL default '0',
PRIMARY KEY (`id`),
KEY `user_id` (`user_id`)
) TYPE=MyISAM

One of the questions in a survey asked about the users age. I have now been asked to pull the other answers out by how the users answered the age question. I've tried a few different ways of searching a copy of the table but the numbers being returned aren't what I'm expecting. I'm not sure what I'm doing wrong. Here's my latest try that's giving me a number that's much too large.
Code:

SELECT count( tbl1.id ) AS count, answers.answer_text
FROM `submitted_answers` AS tbl1, `submitted_answers` AS tbl2, answers
WHERE tbl2.question_id =2
AND tbl2.answer_id =7
AND tbl2.user_id = tbl1.user_id
AND tbl1.answer_id =1
AND tbl1.question_id =1
AND tbl1.answer_id = answers.id
GROUP BY answers.id

The ids I have listed for tbl2 are selecting (or at least I think they are) how the user answered the question about age. The example shown (tbl2.question_id = 2 AND tbl2.answer_id = 7) would be the users that said they were 50+. I'm then (once again, I think I am) relating the 2 table copies by user_id to match up the rows and getting how the users in tbl2 answered the question in tbl2. As I said, this query is giving me much bigger numbers than could be true and I'm not sure why.

Copy Row Data In Same Table
I am trying to make a script that will copy data from around seven tables to another row in the table. This works fine for the first table using the insert

INSERT INTO customers (list, of, fields) SELECT list, of, fields FROM customers where customer_id = customer_number

but in the rest of the fields I dont see how it can work customer_id is the key and I want to make sure they all have the same key. Do I have to do a select first to get all the data where the id = cusomer_number then an insert a new record into the table with the new customer_id generated from the first insert?

Copy Line Of A Table
Is it possible to copy 1 or more lines out of a table into another table?
I am trying to create a kind of a mini backup sys. Every time a user erases/changes a table, I would like to document this change in another table. What I had in mind was simply to copy the line that was changed into another table and keep it for a certain period of time.

Copy Automatically A Table

Copy Records From One Table To Another Table
What is the sql query in mysql which copies all records from one table to another table within a database...? and query that copies records from one table to another that belongs to a different database...

Copy Rows From One Table To Another Table
One is the "main" machine and all the others will synch data up with it it once in a while. Is there a command to insert rows into one table on a different machine using the table on the current machine? Like....

Main Table 1 on main machine e.x. 192.168.1.1
name|email|listdate
------------------------
tom|a@b.com|1-1-2005
dick|c@d.com|1-1-2005
harry|e@f.com|1-1-2005
etc.

Temp Table 1 on field machine e.x. 192.168.1.2
name|email|listdate
-----------------------
larry|g@j.com|6-1-2005
mike|h@k.com|3-1-2005
fred|i@l.com|5-1-2005

i know you can do something like the following if they are both located on the same machine but i don't know how to structure the command for different machines:

insert into real_table (col1, col2) select x, y from temp_table;

Copy The Result Of A Query Into Another Table.
I am trying to make a select with a sum in it and group by account and copy the results in another table.

As the site has the 4.0.25 MySQL version i guess i cant make subconsults. I thought of storying the results in vectors, but up to now it didnt work ...

Copy Changed Records Into Same Table
Is there any way to select several records from one Table, and copy them back to same Table but with changed values of one field (for instance: values of Foreign key field)?
((records with original values needs to remain in Table))

I Need To Copy A Table To Another In The Same Database But With Filters?
I need to copy a table to another in the same database but with filters?

SELECT * FROM table1
WHERE table1.field1 LIKE '%.gif%'
Insert into table1.field2;

Update table1.field2
Select * from table1.field1
WHERE `table1.field1` LIKE '%.gif%';

Insert into table1.field2
SELECT * FROM table1.field1
WHERE table1.field1 LIKE '%.gif%';

I hope that makes sense, any ideas?
