Add Additional Data To Existing Data In A Blob Field
I have a Blob field called "category" that we use to store different categories of job types that our users set up so they receive emails based off of the ones that they have picked. What I need to do is to add 4 new values to the beginning of each users "category" field. I am not really sure how to do this except that I might need to use UPDATE to get it done. This is where it will get tricky, I need to check for the 4 values to see if they already have them and just add the oines that they don't have. Here are the 4 values that I need to check for and add. Allied Health Care, Nursing, Rehab/Therapy, and Other/Pharmacy/Physicians. Here is what a current list of values would look like in the users table and the category column: Code:
Retrieving Empty Data From A Text Or Blob Field Error 80020009
I'm using an ASP script that retrieves information from a TEXT field in my database. But if there are no information in that field it give me the error : "Microsoft OLE DB Provider fro ODBC Drivers (0x8002009) Multiple-step OLE DB operation generated an erros. " ect.. I have two system one that use the old version, which doesn't give me an error MYSQL 3.23.55 and the other version ie: 3.23.58 or 4.1.8 do give me this error. I've seen a couple of comment on various forum about this problem, but I can't seem to find a real solution.
Does Mysql Store Max Size For Data Type Each Time, Or Only What Is Needed For Specific Data?
If I use MEDIUMTEXT, which (if I understand correctly) has a max size of 65k, does mysql use the entire size each time data is written to that column? I have a text field on my site that users fill in, but more often that not, they don't. However, when they do, it can be 1000 bytes or more. Am I wasting space using MEDIUMTEXT or does mysql only set aside 1000 bytes for that column if the data is only 1000 bytes?

Use Mysql Command Line To Unload Blob Data
I have been investigating mysql for a project to store and extract images from a blob field. I have searched on "blob" in the mysql forums and have read the pro and con arguments for storing images in a blob filed vs just storing the link to image file on-disk so we don't have to re-hash them here. I am trying to use mysql and suitable tools as a intermediate storage for inventory items extracted from QuickBooks Point of Sale system to allow the association of expanded text product descriptions and product image files with the exported POS inventory. I have found SQLYog to be a useful tool to allow me to create an inventory table with fields for existing values in the CSV delimited POS inventory unload file and to add blob fields to store text input for expanded product descriptions and product images. I can use any editor to create the expanded product descriptions and paste it into the SQLYog blob field viewer. I can use the blob field viewer to load an image from the disk. When all the inventory items are updated with expanded description and product images, I can use SQLYog to export the inventory table as a CSV file for upload to web site inventory engine. However, I need to upload the product images in mass accumulated in a zip file. SQLYog allows me to select the fields to be included in the CSV file and I select all fields and deselect the image blob field. To assemble the image zip file, I could visit each product's image blob field with the SQLYog blob field viewer and select "save to file" and specify the name for the image. Not too bad for a few products but very time consuming for a 2000+ inventory. Code:
Is It Good To Store Html-formatted Data In Mysql Tables?
I always thought it is best to keep as much html as you can out of your stored data, in order to have flexible data. I am working now on a user friendly news-editor where the user can add news and format the text as wished (put links, bold/underline/italic etc..). I am however a bit struggling with how I should proceed with this data. Do I just store it in the appropriate Mysql table and let it come out on the appropriate front-end news page? And not bother about the html in it? What if a user messes with the html? Should I strip all tags before storing it in the database and add them again while retrieving it on the news-page? If so, I know how to convert a few things, but not everything (like links, bold/underline..). Or are there other solutions? Thanks!
Blob Field Retrieval Via ASP
I have used asp to insert a blob field into mysql db. I have used middleblob for it and somehow when i used response.binarywrite to get the pdf out. The file seems to be corrupted. There seems to be an incorrect file size as the one i retrieve was only 788btyes while the one stored in mysql db is 475kb.
Blob Field Copy
I'm trying to copy blob data (zip files) from one table to another, and am running into problems. The data does not copy over exactly, and then the corresponding zip files will not open. Looking at the files in a text editor it appears there is very little difference, except some 00 00 00's at the end of the "good" file that aren't present in the "bad" file. I've attached examples to this posting. The copy problem occurs if I use sql to move over the data or if I use the upload routine with phpMyAdmin
Defining A BLOB Field
I guess my title covers my entire subject matter I am, for the first time, using BLOB field. When I use TEXT I normally set it to 10 (think to remember this from MS-SQL). What should I use as length when using BLOB? Does it matter?
Changing Encoding Of A Blob Field
I have a database full of binary fields (containing strings) of type cp1257_bin, now, I need to convert it to utf8 (utf8_bin type?). Here's what I've done so far - got the dump, ran it through iconv and converted all strings to the needed encoding, but I'm sure that didn't touch 0xXXX pars of the dump (that's pretty much how binnary data looks in a flat sql dump). Any suggestions on converting that? Thanks.
Can't Insert BLOB Field Into Table.
I'm working with MySQL 3.23.34a, Windows 2000 and try to execute the following: create table if not exists t1 (g longtext,h longtext) INSERT t1(g,h) values (null, null) UPDATE t1 SET g=LOAD_FILE('c:/f1.bin') UPDATE t1 SET h=LOAD_FILE('c:/f2.bin') After the 2-nd UPDATE I have got an error : "Got error 139 from table handler" Size(f1.bin)= Size(f2.bin)= 12Mb. If Size(f1.bin)+ Size(f2.bin) <= 16Mb script is executed successfully. The variable max_allowed_packet= 64 Mb. Is there the way to manage this problem ?

Store More Chars In A Field
Is there a way to store say 2000 charecters in a field? I thought varchar is limited to 255, but I would like to store about 2000-3000. What field type would accomidate that, if any? Or do I need to write text files?
Store AM/PM In Time Field.
I have field type time. I do PHP Code: insert into mytable(mytime) values('06:30:00 PM') . PHP Code: Select * from mytable shows 06:30:00 (without PM). Is there a way to store AM/PM ?
Can't Store More That 45 Characters In A 255 Varchar Field
I have this table: TermName | CREATE TABLE `TermName` ( `id` varchar(45) character set utf8 NOT NULL, `term_name` varchar(255) character set utf8 default NULL, `prefix` varchar(20) character set utf8 default NULL, PRIMARY KEY (`id`), FULLTEXT KEY `TermName` (`term_name`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 on my server and a java app which updates this and other tables weekly. The first time i created this table i created with term_name varchar(45) which afterwards i changed it to 255. The problem is that the field "term_name" won't hold more than 45 characters while it should. I have tested the java pplication and thats works fine. my mysql server/client is 5.0.32 running on debian sarge. I'm using PrepareStatement on the java side to send the String and even at that time it the complete string while when it gets stored in the DB its shorter.
Field Type To Store Text With Commas
I need to change my field type to allow for commas in the field name. So I tried to change my text from "varchar" to "text". However, I am getting this error: #1170 - BLOB/TEXT column 'title' used in key specification without a key length Can anybody tell me if text is the right type to use? If so why isn't my database allowing me to make this change?
Blob And Data
I create table where I stored image (using medium blob data type) and description about image. While retrieving fields, I can see only images not the data. I want to display image with description in one page. Below is the code: -------------------- $id = $_GET['id']; $query = "SELECT * FROM upload WHERE id = '$id'"; $result = mysql_db_query('DATABASE',$query) or die(mysql_error()); if(mysql_error()) echo mysql_error(); $desc = mysql_result($result,0,'desc'); $name = mysql_result($result,0,'name'); $type = mysql_result($result,0,'type'); $size = mysql_result($result,0,'size'); $content = mysql_result($result,0,'content'); header("Content-length: $size"); header("Content-type: $type"); echo $content; echo $desc;
BLOB For Storing Data
I'm implementig a java web application using MySQL as database. The main function of the application is basically to redistribuite documents. Those documents (PDF, DOC with an average size around 2Mb) are stored in BLOB column. The amount of documents for the first year should not exceed 5/6 Giga, but I cannot make prevision for the next years. Those documents are mainly just accessed (update and delete are not so common operation) I would like to know if someone else is using a similiar approach. If so, it is scalable?
Corrupt BLOB Data
I'm using mySQL to store data in a blob field. This seems to work on some machines, and not on others. What usually end up happening is that the data ends up getting corrupted either while uploading or downloading it. I am not sure what's wrong. Using Perl to upload and download the data. I am using the latest DBI package. binary file size = 4168 bytes Possible errors: *these errors depend on what machine the code is run on 4168 bytes retrieved, but contains incorrect data <4168 bytes retrieved <4168 bytes retrieved <4168 bytes uploaded >4168 bytes uploaded The Perl code works on my unix machine, but not on my win machine The Perl code works on my co-workers win machine, but not our unix server.
LOAD_FILE Into BLOB Corrupts Data
I am trying to load jpg's, pdf's, etc into a BLOB field. (Please no discussion on the Pro's And Con's and why am I doing this...) I am not using PHP. I try to load the file from the FS with LOAD_FILE(). Then I display these from the DB with a browser. Some of these work perfectly. No problems at all. Others seem to have corrupt data. I am trying to figure out if anyone else has had this issue. I know that people do this with PHP and use addslashes() to escape characters. My whole system is works in UTF8. I even tried with a PHP script to see if that was it and still no luck. Does anyway have any ideas? The DB is 4.1.8. I have tried 4.0.23 and 4.0.18 (which on my old RH AS 2.1 seemed to work). The OS is RH9.
Best Way To Store This Data
I'm doing a bit of a site where users can upload replays of games. The table (called 'replays') will have fields like id, name, date_uploaded .... which take up about 10 feilds. But there also has to be a way to store data on each player. There can be up to 8 players in a game and the database must somehow record: a) the name for each player b) a rating for each player c) and a second rating for each player. Any tips on how to do this? I cant imagine having a database with 40+ feilds called player1rating1, player1rating2, player2rating1

Best Way To Store Team Data?
I'm working on a sports project, and I'm trying to figure out the best way to store the names of players on a team in a database. For example, I might have an entry for "Los Angeles Lakers" which needs to have information containing the players "Kobe Bryant", "Lamar Odom", "Derek Fisher", etc. Currently I just have 3 columns: Unique Team ID (integer), Team Name (varchar), and Players (varchar). I'll enter the Lakers as: "001", "Los Angeles Lakers", "Kobe Bryant, Lamar Odom, Derek Fisher" and then if I need to get out individual players, I just "explode" the array in PHP along the commas for the Players field.
Store Data For Menus
I wish to use MySQL to populate the names for several HTML menus using PHP. Some of the names are used in all three menus, however, others are only used in one or two of the menus. To eliminate duplicating the names, I only want one table to store all the names. I have two ways of doing this, and would like an opinion of which one is best. One would be to store the names along with three columns to indicate which menu uses a given name, and then a querry could only return the applicable names. ID Menu_Name Menu1? Menu2? Menu3? 1 Menuname1 Y Y Y 2 Menuname2 N Y N 3 Menuname3 Y N N 4 Menuname4 N N Y The other way would be to only include the names in the first table, but then create a separate table for each of the menus, and use a subquerry to return only the appropriate names. ID Menu_Name 1 Menuname1 1 Menuname2 1 Menuname3 1 Menuname4 Menu1Table ID Name 1 1 2 3 Menu2Table ID Name 1 1 2 2 Menu3Table ID Name 1 1 2 4 Any suggestions on the best approach?
#1101 - BLOB/TEXT Column 'data' Can't Have A Default Value
Im using phpmyadmin for working with mySQL. (its my local version, im just trying to use it). When i want to add BLOB type column in table - that mistake appears: #1101 - BLOB/TEXT column 'data' can't have a default value I turned off strict mode (from my.ini, or by config wizard), but it did not help. I've found alot about that problem in that site, but i dont uderstand anything, because im just Newbie. So what should i do to make BLOB/TEXT column have a default value? Is it possible without using hard way, just by changing something, or download any new version?
BLOB - Error 22001 Data Too Long For Column
I'm using .net connector and attempting to store a c# byte[1200] array into a BLOB field in my InnoDB table. I'm getting the error: {"#22001Data too long for column '_ch1RawData' at row 1"} If I change the array to have a length of 120, it seems to work OK. This makes no sense to me, 1200 isn't too big? From what I have read, a BLOB's max size is 2^16 + 1 which puts me safely in the valid size range for this array.Here is a snip of code that I'm using to save the blob: <code> MySqlCommand command = new MySqlCommand( Settings.Default.AddTestResultSprocName, connection); command.CommandType = CommandType.StoredProcedure; //.. code that opens the connection, etc command.Parameters.Add( new MySqlParameter("_ch1RawData", ch1Raw)); command.ExecuteNonQuery(); </code> Does anyone see a problem with this?
No Line Breaks In BLOB Or TEXT Data Types
I have set up a database that is going to accept fiction and poetry submissions. I need to find out the best way to read these submissions back to a web page that will display line breaks correctly. Right now I just left them as BLOB data types, and line breaks are not displayed when sent back to the web page.

Inserting Blob Into MySQL Database
I'm facing a strange problem when I try to insert a blob in my SQL database. I'm implementing a web application using Struts and hibernate and My SQL for the database. The application runs fine when I insert the blob (which is an image in my case). However, I'm unable to see the row in the table when I go to MySQL and do a "select" statement. All I get are a bunch of dashed lines that go on forever. I simply followed instructions given in a struts and hibernate tutorial to insert blob data and I don't get any errors when I run the application. Following are the details: Code:
MySQL 4.0, Max_allowed_packet And Blob Insert
I'm running MySQL 4.0.24 on Debian Linux and have a problem with a very large blob insert query - it always fails with "#2020: Got packet bigger than 'max_allowed_packet'". I searched the docs and found some references that this value can not be greater than 1 GB with MySQL 4.x - indeed, when I change it to some value greater than 1 GB, it has no effect, the value just stays at 1 GB (1073740800 Bytes). The query is from an application (mnoGoSearch), so I can't just go and split the query into smaller ones. The tables in question are all in MyISAM format.
Returning MySQL Blob To Page.
I have a blob field in a database and a type field. The blob will either contain a zip file or a gp3 or gp4 file. I need to return this blob so that the user can download the file. I can download a zip simply be setting header type to application/zip and returning the blob but how do I return the others, can I just put application/$type?
Extracting Text From MySQL Blob
I'm working on reports for a third-party application that uses MySQL. There are a few fields that store text in a blob field. I'm using ASP (classic) and I know I can use Response.BinaryWrite to simply display the text from a blob. However, now I want to generate an xml document using the same data, and need to replace some instances of "&##38;" with "&". Somehow, using "substring(blobfield,1,2000)" in my request works for one blob field, giving me normal text I can work with. However, I can only go as high as "substring(blobfield2,1,255)" with the other blob field. 256 or higher yields a bunch of question marks "?????????" instead of normal text. While using 255 is okay, it does truncate the field for a few records.I've tried using CONVERT and CAST on the blob fields, but that wasn't working (I might have had the wrong syntax).
