This is the error I get:
#1118 - Row size too large (> 8126). Changing some columns to TEXT or BLOB may help. In current row format, BLOB prefix of 0 bytes is stored inline.
I searched the error and found some people talking about adding this to /etc/mysql/my.cnf
innodb_log_file_size = 512M
I did that and restarted Apache but I still get the error. I’ve also updated my php.ini file with:
memory_limit = 600M
I’m running a 1GB / 30GB Disk Ubuntu droplet. Is there something I am missing?

I believe that the error is trying to say that when you add up the sizes of your 163 fields, they are larger than the 8126 that your current configuration is allowed.
You are actually attempting to create a row definition or place holder for the data which will have 163 different columns/fields whose total data width is larger than 8126.
Since you are maxing out at 8126, you might look at changing your innodb page size which is usually about double the row max. It’s currently at 16K. I have heard that it can be changed to 32 or even 64K. Or alternately, you can vertically split the table by putting the most important used data in table A and the least used important data in table A1 then linking them in reports and elsewhere via a primary->foreign key. If you just copy paste the create table statement here, it may be obvious to others here as to why the estimated width is larger than the allowed 8K.

I see this example which might visually prove to be helpful to you: mysql> CREATE TABLE t (a VARCHAR(8000), b VARCHAR(10000), -> c VARCHAR(10000), d VARCHAR(10000), e VARCHAR(10000), -> f VARCHAR(10000), g VARCHAR(10000)) ENGINE=InnoDB; ERROR 1118 (42000): Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. You have to change some columns to TEXT or BLOBs
I tried adding this to my.cnf:
I also altered the table to use
ROW_FORMAT = COMPRESSED
.Unfortunately this did not work. I exported a copy of my DB without any content (just the structure) and tried importing that. When I tried that, I got the same error regarding row size. I only have a single table but it has 163 columns. I don’t understand why the error is regarding row size when I’m not even importing any rows!
I’ve set most of them to be
TINYTEXT
, thinking that would use less memory thanVARCHAR
, but that doesn’t seem to matter.The specific error you ran into isn’t one I’ve encountered before myself but doing some searching led me to this Stackoverflow thread which included an answer that worked for another user who encountered the “Row size too large” error you’re seeing.
@ryanpq Ok, I found out what groups are and added this to my.cnf:
This allowed me to restart mySQL successfully, however, I am still getting the error.
@ryanpq That’s probably my issue but when I run the restart I get this:
Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
When I run
systemctl status mysql.service
I see this:What is the
preceding group
that is being referred to?When changing your my.cnf you’ll need to restart the MySQL service, restarting apache will have no effect:
That doesn’t sound like a problem with phpMyAdmin. If you created database in advance before importing, make sure that it’s the same engine (InnoDB, MyISAM) as original one.
