Hi,

I have never seen this error message before - and am struggling to find a solution!

CDbCommand failed to execute the SQL statement: SQLSTATE[42000]: Syntax error or access violation: 1118 Row size too large (> 8126).

The offending row in the table was varchar 500, so the first thing I did was change that to LONGTEXT in the vain hope this would help - but to no avail.

The error message goes on to say "Changing some columns to TEXT or BLOB or using ROW_FORMAT=DYNAMIC or ROW_FORMAT=COMPRESSED may help. In current row format, BLOB prefix of 768 bytes is stored inline."

There is unsual (at all) about the text being entered for this row and I've got other columns which are LONGTEXT with no problem at all !

Any help much appreciated !!!

How are you doing the insert?  What programming language?  And what version of MySQL are you using?

can you please show the full table description.
also, do you maybe have some trigger on the table that does something else behind?

Hi,

Many thanks for getting back to me. I'm using PHP. MySQL version is  5.5.35

Doesn't make any diffrence if I enter the data via the site admin or directly using PhpMyAdmin - get the same error emssage.

I've included the full table schema below - the offending columns are eg homeRightCol4 which as you can see I've now set to LONGTEXT (it was originally VARCHAR 500) ...

I have never come across this error before!!

Many thanks in advance!

the "error" is not in the table definition "per se", but in the total data volume per row.

to "fix" this, you will need to split the table into several tables.

my suggestion would be to move:
`homePageOnly` mediumtext NOT NULL,
  `homeVideo` mediumtext NOT NULL,
  `homeTopR1` mediumtext NOT NULL,
  `homeTopR2` mediumtext NOT NULL,
  `homeTopR3` mediumtext NOT NULL,
  `homeLeftCol1` mediumtext NOT NULL,
  `homeLeftCol2` mediumtext NOT NULL,
  `homeLeftCol3` mediumtext NOT NULL,
  `homeMidCol1` mediumtext NOT NULL,
  `homeMidCol2` mediumtext NOT NULL,
  `homeMidCol3` mediumtext NOT NULL,
  `homeMidCol4` mediumtext NOT NULL,
  `homeRightCol1` mediumtext NOT NULL,
  `homeRightCol2` mediumtext NOT NULL,
  `homeRightCol3` mediumtext NOT NULL,
  `homeRightCol4` longtext NOT NULL,

into 1 table that "translates all those columns into rows" with:
`site_page_id' (foreign key)
section_key varchar(50) not null
section_data longtext

and do like this;
id  , 'homePageOnly',  ...
id  , 'homeVideo',  ...
etc ....

this technique will then not only avoid the error, but also make it much simpler to add new "columns" to your code: just adding a new row without having to change the "schema"

Hi,

Many thanks for getting back with this solution - that would make sense as the problem only occurred after adding a bunch of new rows. I was not aware of this restriction!
