I'm guessing this is because I have too many custom fields.

It also forces you to read/write more data at once, while one of the interesting things about overflow blob storage is that if the columns aren't requested as part of a You may just have a table with 50 variable length columns, but if their max length is, say 50 bytes, you still have plenty of room for local storage. Is there a role with more responsibility? LimeSurvey 1.87+ (build 8518) MySQL 5.0.45 using InnoDB Thanks in advance.
The first thing to highlight here is the need for proper testing. Innodb_file_format=barracuda If you're putting so much data into one row you probably don't need all of it for every query and could probably improve performance by moving some of it to another Perhaps your purpose would be more effectively served by creating a table where each TEXT-N field is it's own row in the database and related rows are indicated by a shared https://ellislab.com/forums/viewthread/154842/ Why does argv include the program name?
Definitely one of the things I was happiest about when reading up on Barracuda. This is a rather simple problem, but due to it's nature, it may only affect you after you already have a system running in production for a while. The administrator has disabled public write access.

Die korrektere, ausführlichere Erklärung erspare ich mir hier, da es im verlinkten Blogeintrag gut genug erläutert wird. useful reference Combine all your variable length fields into a single BLOB and do the splitting at the application level. I even changed the type of all fields from text to mediumtext, but nothing working... Limit the size of variable length columns This is a quite obvious approach, and if your data allows it, it's also one of the simplest to implement.
SitePoint Sponsor User Tag List Results 1 to 23 of 23 Thread: Got error 139 from storage engine Thread Tools Show Printable Version Subscribe to this Thread… Display Linear Mode Switch Reading the MySQL documentation, it appears that InnoDB can only handle 8000 bytes per row including the first 768 bytes of each blob (text, in this case) in the row. If your row has variable length columns and the complete row size exceeds this limit, InnoDB chooses variable length columns for off-page storage. my review here Is there an easy way to convert the table from InnoDB to MyISAM (crosses fingers…) J.

Failing that, could the survey admin be warned about this when $databasetabletype='InnoDB' is set? Any time a user fills all of them with 768 or more characters, the UPDATE will fail. That is, the maximum row length is about 8000 bytes. LONGBLOB and LONGTEXTcolumns must be less than 4GB, and the total row length, including BLOB and TEXT columns, must be less than 4GB. get redirected here Security Patch SUPEE-8788 - Possible Problems?
Since LimeSurvey knows which database engine is being used (it's even defined by the user in $databasetabletype), it would be nice if it checked surveys before they run into this limitation. No idea why. Having 13 long columns in one row is not very common… Splitting the table into smaller ones is the way to solve this. If you have a modular data access API, you shouldn't have to change code in a lot of places.
Execute the survey and enter at least 768 characters in each text field. Solved my problem. Also, since MySQL 5.03 , varchar can have length up to 65,535 bytes so be aware of your variable-length columns. You can find more information about this functions here.

This means it is possible that you hit this error after converting from a native language character set to utf8, as it can increase the size dramatically.

And is your database running in MyISAM or InnoDB?
