MYSQL :: Update / Insert Data Using CSV File

Insert Data Via A .sql File
I've just started using php and Mysql for the first time. I am following a couple of sample sites that are created in a book. I have created the database with the tables. I have a file called populate.sql which contains some sample data. The instructions in the book show that to use this file I can use Mysql with the following :

mysql -u root -p < populate.sql ;

Do I have to use root or can I use another user. I have tried it with another user but it doesnt work. I get a syntax error.In another example I have managed to use the LOAD DATA INFILE.... command. I would just like to get this method to work. I guess its something really daft but its doing my head in.

Insert File Data Into Text Field
I've built a database locally and have inputed some information. I
need to go back and update some records, specifically by taking long
pieces of text and putting them into text fields.

Cutting and pasting in the command prompt for windows isn't such a
good idea. Is there a way to update an existing record by importing a
text file into a text field?

All the info I'm seeing in the MySQL manual and in these groups is for
importing text-deliniated files.

INSERT Or UPDATE Depending On Row Data....
I have a form that submits to a php script which in turn sends the data to a table in a mysql database.

$sql = "INSERT INTO scores (scoreid, xuser, xscore)
VALUES ('', '$_POST[xuser]', ('$_POST[xscore]'))";
$result = @mysql_query($sql,$connection) or die(mysql_error());
?>

This is the main section of that specific script at the moment. As can be seen, there are three fields, scoreid, xuser and xscore.

What i want to do is Insert a new users score as it is currently done so, HOWEVER, if the user already exists in the database then instead of a new tuple being entered for them, how can i do it so that their old tuple is overwriten/updated instead?

Error On Update Or Insert Data But No Message
I have an application on asp and mysql 5.0, connecting with ODBC 3,51. When the application insert data or update data, MySql don't send error message, but the data don't update or insert. The transaction is ignored!!!!. Then, on my application I can't detect error. My code:

set Command1 = Server.CreateObject("ADODB.Command")
Command1.ActiveConnection = MM_base_STRING
Command1.CommandText = "UPDATE EXAM SET MaAnt='"&MaAnt&"',Mois='"&Mois&"',Annee='"&Annee&"',[...]WHERE Id_Exam='"&id&"'"
Command1.CommandType = 1
Command1.CommandTimeout = 0
Command1.Prepared = true
Command1.Execute()

Have anybody an idea?

Truncate Tabel And Insert Data How To Update Indexes?
Once every day our financesystem updates data that I uses for my database. Some tables I truncate and reinsert data to get the latest changes in our customer and prospect database. Others I delete from a certain date to obtain best economical data and finally one database with 14M records I add records that has been added since the day before.

What I find is a very slow system and the funny part (but I think understandable) is that if I do not update for lets say a week (because I test stuff) the queries are fast and smooth.

That tells me that the problem is indexing.

So if I truncate a table, how to update indexes or can I do that at all?

The Optimize tabel doesn't help me here :(

I use MyISam and not InnoDB would that make any changes?

What about indexes are they needed (those I create)? or can MySQL handle that better?

INSERT/UPDATE W/data Conversion To UTF8 (ex: JosÃ¨ Feliciano)
I have the following string of "JosÃ¨ Feliciano", when I insert/update into the mysql db I need the db to convert the [Ã¨] to the UTF-8 value of [è].

Is this possible via the db... I'm sure it is... if so, how?

I have also tried the following and do not see the expected result.

CONVERT(_latin1"JosÃ¨ Feliciano" USING utf8)

Also, when I do use CONVERT it chokes when there is a single-quote in the value that I am inserting... even with the value is surrounded by double-quotes. What is up with that.

CONVERT(_latin1"Ramblin'" USING utf8) ??

CONVERT(_latin1'Ramblin'' USING utf8) ??

Need To Insert Data From A Text File Into A Medium Text Field.
How can I go about inserting data into a MEDIUMTEXT field from an existing text file using Java.

Split Innodb Data File Into Smaller Data Files
we configured innodb configuration with default my.ini settings. now data file is increased more than 40 GB.After that we come to know that we need keep the settings like below

#innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend

so that it will keep on creating 2GB data files.
Now how we can change the settings and splitting the data file of 40 gb please.

UPDATE Or INSERT
Kind of worked myself into a weird place in my current application. Where I find myself at is with a single form that is supposed to handle both updates of existing rows and insertions of new rows. The way I want this to work is:
1) If the ID is specified and references a valid row, update that row
2) If the ID is specified but does not reference an existing row, insert a new row
3) If the ID is not specified, insert a new row

Now, (3) is easily done in my application - just test if the ID was specified by the user. Simple. Nothing to it.

What I'm wondering is if there is a way to do both (1) and (2) in a single MySQL query and receive feedback such that I can in my application inform the user whether an update or an insert took place. I could do this with two seperate queries (query for the ID; if I find the row update it, otherwise insert a new one), but I'd like to do it with a single one if possible (mostly because I want to expand my skills with complex SQL queries).

Update Or Insert Sql
I am using this query to update tableone based upon the values in tabletwo. I really like this query because it works very fast.

PHP

UPDATE tableone n, tabletwo c
   SET n.sec  = c.sec,
       n.cat = c.cat,
       n.published = 1
WHERE n.section = c.section
   AND n.category = c.category

This works great however I cant seem to get it to insert or append if the data already exists. It just overwrites the data.

My difficulty is that I need certain columns to be updated (overwriting the data) and other columns to be inserted or appeneded to (adding to the data).

Is a stored procedure the best way of doing this?

Or, is there a way of adapting my sql to cater for this?

Need To Use UPDATE Instead Of INSERT INTO
I need to UPDATE exisiting rows and populate
the fields using only the resources in this INSERT statement.

INSERT INTO cms.project_event (projectPhaseID,sortOrder) SELECT
cms.projectTemplate_eventTemplate.projectTemplatePhaseID,
cms.projectTemplate_eventTemplate.sortOrder
FROM cms.projectTemplate_eventTemplate WHERE
cms.projectTemplate_eventTemplate.projectTemplateID = '1'

Any clue pointing in the right direction will be of great help. Im not providing alot to go on just the to update the two fields from the other table instead of INSERTING new rows.

Last Update/insert
Can I know the time when the last UPDATE or INSERT occur in a table in a database?

UPDATE And INSERT In One Go?
Is it possible to create a query that will do an UPDATE or an INSERT depending on certain data already in the database?

Eg I'd like to record a user's vote. If this user hasn't voted already, an INSERT is called for, otherwise an UPDATE. Right now, I'm SELECTing first, checking whether the user's id is already in the votes table, and if yes, my query's an UPDATE, otherwise it's an INSERT.

This needs two hits on the DB however, and I'm someone who likes to limit the amount of DB hits as much as possible.

Update And/or Insert?
I'm using MySQL with PHP. I want to update a record if it already
exists. If it does not exist, I need to create a new record.

Is this done through a simple SQL command, or do I need to use PHP to
negotiate two separate UPDATE and INSERT statements?

After Insert, After Update
I am taking my first and last class in programming as I can't make sense of the textbook or teachers instruction (but I am determined to get at least an A or B in this class.) So if anyone could tell me in VERY simple terms how to write an after insert and after update trigger I would be very much grateful.

INSERT / UPDATE
I'm having trouble using the IF statement.
What I want is to do either a INSERT or a UPDATE depending on the SELECT statement.
No mather what i do, it gives me an error on the INSERT statement. Isn't allowed to have a INSERT/UPDATE statment inside a IF statement?

This is what i'm trying:

SET @param = (SELECT)

IF @param IS NULL THEN
INSERT...
ELSE
UPDATE...
END IF

INSERT Or UPDATE
I need using a SELECT statement, but is there a way to make this work on INSERT or UPDATE statements as well?

In other words, I can do:
SELECT MONTH(deadline) FROM projects ...

But can I do something like:
UPDATE projects SET MONTH(deadline)='11' ...
where the rest of the date stays the same, but only the month is updated?

Doesn't seem to work, and I don't see any examples in the manual comments, but it sure would be nifty.

Update Or Insert
I have to create a database with 8.000 entries.
It will be the top entries it will have. Now... what is faster ?
a) to create the table before with 8.000 rows and the id field from 1 to 8.000 (primary key...) and then do UPDATE's
b) to create the rows as they have to be created with INSERT's ?
In the middle of the process it will be SELECT's from other users.

Insert If I Can't Update
I check for the data to exist. If it does, I UPDATE, otherwise I INSERT. Is there a way to do it better, more efficiently?

UPDATE Or INSERT
I am looking for a solution to an update-type problem. Users enter name, address, etc etc. I have set the first_name & last_name fields to be jointly unique, so that no two records can exist with the same first and last names the same (e.g, no 2 records with 'Joe Bloggs' as first/last names.).
Now if users want to correct, say, their address, it will not allow them to since a record already exists with their first/last name.
Is there a SQL statement that will allow me to bypass the UNIQUEness constraints when other fields need to be updated?
(And related, if the UNIQUE fields are updated, it currently creates a new record but leaves the old one there. I need to overwrite the old record but keep the same ID number primary key.)

INSERT/UPDATE
I've got an array in PHP, which is identical to a row in mysql:

Code:

array
(
'key' => 'somekey',
'column1' => '...',
'column2' => '...',
'column3' => '...',
);

If 'somekey' does not exist in the table, I want to INSERT this array as a new row. Otherwise, I want to UPDATE the row which has the key 'somekey'.
Is it possible to do this in a single query? Cause now, I'm first INSERTing a row and if that fails, I try an UPDATE instead.

Insert/update
I have a table of x/y values and a set of 'new' x/y values.
For each of my new x values that already has a record in the table, I want to add the new y value to the corresponding existing y value.
If there is no x value in the table, I want to create a new record with the new x/y values.Is there a simple (atomic) way of doing this?

Using PHPMyAdmin To Insert A Text File
I want to upload a text file.  How do I do this?  Do I use the following statement (This is what I used to upload to a local MySQL database in the past.)

LOAD DATA INFILE 'C:WebInfoeva1-18-05.txt'  INTO TABLE egov
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '
'
(ID, LSIPN , ManPN, DESCRIPTION, SPSCCode, UnitPrice, UnitM, LeadTime, ManufacturerName, PaymentTerm, MinimumOrder, MaximumOrder, ServiceAreas, Image, Generic, Remanufcatured);

However when I use this I get an access denied error.  Do I need to move the text file local?  If so how do I give the file path name on a linux system?

Insert A File In A Blob Field
I have tried to use an assignment example....

I load the file in a ADODB.Stream object

stream.Type = adTypeBinary
strmFile.LoadFromFile (filename)
recordset.fields("blobfield").value = stream.Read

I cannot update a field..... (other field I use the "UPDATE....." SQL statement......)

Insert Or Update If Exist
what is the sql statement that can insert or update the record if it exist.

Update / Insert / Delete Log
I'm wondering if there is any way to get a lot of recent update/insert/delete statements performed on a db by a particular user?

Insert Then Update That Record
I'm using PHP to insert contact information in to a database. Confidentiality requirements have made the design change so that the private information be entered separately. I've modified Form 1 so that it contains the public information and added a button. The button does two things, it inserts the record in to the database then draws the private information form.

My question is, can mysql give me the last row inserted so I can pass that information on to the form and use it in my update query? I tried doing it by ID in that table but the id is not assigned until after the submit button is pressed. I can do another query but thought it would be slick to do it by row.

Insert On Duplicate Key Update
Is it possible so do something like this

"insert * from TempTabel on dublicate key update 'all fields'; "

So I don't have to write every column name. I need this, so I can use the same code on multible tabels. I could use replace, but then the foreign key in other tables are not updated.

If Exists Then Update, Otherwise Insert
provide a very simple if, then, else clause in MySQL?
If a customer named 'bob' is already in the database, I want to update his id. If he is not already in the database, I want to insert him.
What would be the best way to do this?
I get errors for the following:
IF EXISTS
(SELECT 1 FROM customers WHERE name = 'bob')
THEN
UPDATE customers
SET id = '007' WHERE name = 'bob';
ELSE
INSERT INTO customers(id, customer)
VALUES('007', 'bob');
END IF

Two Timestamps For Update And Insert
I need to record date updated which a timestamp does, but also the date inserted. Can I do this all from the mysql database, or do I need to have a variable date inserted in the php. The first option appeals to me more.

Simple Insert And Update
Im having a rather irritating problem..because its so simple and I just cant figure it out.In my database I have some company info and the primary key "companyID" is used to reference it in several other tables.
however in phpmyadmin I cannot figure out how to set it to automatically generate when I create a new company in the company table and then propogate to all the tables it links too.

Unable To Update And Insert
I have a weird problem which is i able to access to the DB, able to do a select but unable to update and insert.
This is the scenario.
The existing running db is called as 'abc'. I dump it out and the i restore it as 'abcv2' and add in few column and insert value in. Then my application able to access the db. Able to do a select but unable to perform insert and update. No error is show in my application. Application wise i not the problem as it able to do so with others db.
I suspect is the privileges problem therefore i create a user and grant all access to that user. But the same thing as unable to update and insert.
Any idea of my problem? I think if i change the database name from a dump file won't cause this problem right.
What i can do now is i get the dump file then i open it with notepad and do the necessary changes. This is working fine but i would like to know what is the cause for this problem.

Insert Or Update Records
What's the best way to achieve this?
To simplify the problem, lets say I have a table with two columns, 'id' and 'value'.
Now, I want to pass an object through remoting (amfphp, irrelevant really but anyway) to either update existing rows or insert new ones.
The object I'm passing has corresponding fields, and if there is a match on the 'id' field then update it, if not insert a new row.
So I guess I need to first pull out all of the id's and compare them to the ones in my object, then seperate them up to ones that need updating, and ones that need inserting.
I can't quite see what the best way of doing this is. Either in code e.g. PHP or is there a MySQL statement to do it the quick way?

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:

Select, Update, Insert. Efficiently?
First, I want to say that I didn't design the databases and I wish I could fix them, but I can't.

There is a table, s01_Baskets, that tracks the users basket throughout my store.
There is a table s01_StoreKeys, that holds the next ID for every field used in tables. In this case I'm interested in is the basket_id.

What I need to do is create a new "basket" for a customer. To do this I need to select the key for this basket_id:

SELECT
s01_StoreKeys.maxvalue
FROM
s01_StoreKeys
WHERE
s01_StoreKeys.type = 'Baskets'
Then I can "create" a basket by inserting a row:

INSERT INTO
s01_Baskets
(
s01_Baskets.session_id
, s01_Baskets.cust_id
, s01_Baskets.basket_id
, s01_Baskets.order_id
, s01_Baskets.order_proc
, s01_Baskets.last_update
, s01_Baskets.ship_id
) VALUES (
'".session_id()."'
, Ɔ'
, Ɔ'
, Ɔ'
, Ɔ'
, '".microtime()."'
, Ɔ'
)";
Then I have to update that field for next key for the next basket.

UPDATE
s01_StoreKeys
SET
s01_StoreKeys.maxvalue = '".$basket_id+1."'
WHERE
s01_StoreKeys.type = 'Baskets'
UGH. I'm not thrilled doing it like this (one bad query, or if another process jumps in at the wrong time, I've messed up the baskets....)

Is there a better query for this? I'm pretty sure I can do the insert and select as one, but I need the basket_id(+1) for the update also. I don't know of any way to do all three queries in one. Can anyone see a better way to do this queries (ignore the poor design)?

Auto-increment And Update/insert
I have the following problem with a MySQL update/insert.

my problem lies in the fact that I have to insert a new row between 2 existing rows. the table is sorted by ID and has ID as auto-increment so I cannot insert a new row between 2 rows as inserting will assign the insert a new ID number...

I figured now I have to do an update and then loop till the end of the table and then do an insert at the end..

INSERT And UPDATE Similar Statements?
At least as I know it, INSERT goes like:

INSERT INTO table (Col1, Col2) VALUES('Hello', 'Goodbye')
While UPDATE goes like:

UPDATE table SET Col1 = 'Hello', Col2 = 'Goodbye'
Is there any way I could make them the same format, such as:

UPDATE table (Col1, Col2) VALUES('Hello', 'Goodbye')
?

Insert On Duplicate Key Update Question?
I have UNIQUE comp keys with 3 columns. I want to insert new rows if the data doesn't match one of the 3 columns. If they match, don't do anything. I am trying to do it with one query without doing select first and bunch of comparsion then either insert or update depending on the comparsion.

I am think of using this:
INSERT INTO mytable ('col1', 'col2', 'col3') VALUES ('mydata1', 'mydata2', 'mydata3') ON DUPLICATE KEY UPDATE col1=col1, col2=col2, col3=col3

is it going to work? I think it first tries to insert my data as a new rows if it is not duplicated. If duplicated, it will update the data with its old data. But update will ignore the operation since it's the same data.

Convert UPDATE Query To INSERT
I have an SQL dump file of a sql database that was generated with the UPDATE export type. The file contains code for generating the various tables inside the database along with the UPDATE lines for the table data.

Is there a way to process the dump file such that all of the UPDATE instructions are converted to INSERT instructions? I have to restore the database from scratch so there are no existing table rows to update.

Insert And Update In The Same Query (mySQL-3.23.58)
I am using mySQL-3.23.58 at my school. Since triggers are not available is there a way to do an insert and an update in one query?

Update Record, Insert New If Doesn't Exist
I have a table that contains a list of parts used in a repair. The table contains foreign keys to the part and job concerned. it also contains data of time taken and status.

This data is read into a gui and the user can update the time taken and status. The user can also insert new parts in the gui.

is it possible to write an sql statement that will update the existing records and insert new ones if none already exist?

at the moment I'm having to try and update each record one, at a time and check the number of rows modified, if zero then insert a new record. all of which is done within the application. It works but doesn't seem very elogent...

INSERT / UPDATE A Row By Its Position In The Table?
Is there a way to insert or do an update of a row (aka record) by its position in the table, for example, the 5th row of the table? I know you can select data in such a manner, using the LIMIT 4,1 clause, for example. Does this work with insert/update as well, and if so, what's an example SQL syntax?

No Read Or Write Between INSERT And UPDATE
I am using mysql with the InnoDB engine. I wrote a perl script that
first selects something from a table, and then updates a second table
based on the select from the first table. I need to make sure that
there is no read or write to the tables while my script performs the
insert and update.

I looked at

http://dev.mysql.com/doc/refman/4.1/en/lock-tables.html

and it says this:

---------------------------------------------------------
If you are using a storage engine in MySQL that does not support
transactions, you must use LOCK TABLES if you want to ensure that no
other thread comes between a SELECT and an UPDATE. The example shown
here requires LOCK TABLES to execute safely:

LOCK TABLES trans READ, customer WRITE;
SELECT SUM(value) FROM trans WHERE customer_id=some_id;
UPDATE customer
SET total_value=sum_from_previous_statement
WHERE customer_id=some_id;
UNLOCK TABLES;

Without LOCK TABLES, it is possible that another thread might insert a
new row in the trans table between execution of the SELECT and UPDATE
statements.
---------------------------------------------------------

However, I am using InnoDB and it DOES support transaction. So, does
that mean that even if I don't lock my tables, it will still work? If
not, what do I need to do?

Restore Data By Copy The Data File
i have restored the data by copying the data file into c:mysqldataabc It works.

But, I have the problem as I want to copy another updated data files (*.frm, *.MYD, *.MYI) into the folder.

All data is lost! but, the size of the data file is not zero.

If I do the same action to replace the old data files, it works again.

Now, how would I can restore the updated data?

Dumping File With Using Update Syntax
I am trying to figure out a way to use mysqldump (table is too big for phpmyadmin) or another means to dump a file. Within the file, I don't want the insert syntax. What I would like to find out how to do is basically update each record (except for the field in the table that counts clicks) and then insert the records that are not in the database already.

I need this in a file format because I upload the file to my server after building the 1 million record DB locally.

INSERT Syntax For Text File To Load Into Tables?
I have successfully created a number of tables in my database and am looking for an efficient way to load data into the tables. I have the following (successful) command to find the text file and load it into the target table:

"load data local infile 'C:mySQL abledata.txt' into TABLE checks;"

It loads into the 'checks' table successfully, but the data is incorrect. What is the syntax of the INSERT command that I'm using in the text file itself-- assuming that I do use the INSERT command? Here is what I have in the NotePad text file I'm using, which only produces zeroes in the first and third columns:

insert into checks values
('1', 'Ma Bell', '150', 'Have sons next time',
'2', 'Reading R.R.', '245.34', 'Train to Chicago',
'3', 'Ma Bell', '200.32', 'Cellular phone',
'4', 'Local Utilities', '98', 'Gas',
'5', 'Joes Stale $ Dent', '150', 'Grocieries',
'6', 'Cash', '25', 'Wild Night Out',
'7', 'Joans Gas', '25.1', 'Gas');

Generate INSERT SCRIPT From Tab-Delimited Text File
Any recommendations on how to generate an INSERT SQL script for the
records in a tab-delimietd text file? The limitation is that, while I
do have command-line mySQL access locally, I do not at my remote host,
so I will need to come up with a solution that I can run via something
like phpmyadmin, mysqlcc, or TOAD for mySQL.

How To Insert And Update Multiple Values In One Record
How do I insert and update multiple values in one record. e.g.

1. How do I insert "dogs,cats, snakes" in one record
2. If I have "dogs, cats, snakes" in one record and I want to update it and add 'pigs' to make it "dogs, cats, snakes, pigs", how do I do that?
