We are having database in MySQL 5.1, we have taken the DB backup from MySQL 5.1 and trying to restore in MySQL 5.6. We are getting below error:

ERROR 1118 (42000) at line 603: Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs.

Found the error while creating a table. The table details are below:

1) Table is of type MyISAM.

2) Table is having total of 140 columns.

3) Table is having around 105 columns with datatype varchar(255).

4) Table is having 5 columns with datatype longtext.

I have done few comparisons/changes, but still I am getting same error:

1) Both the MySQL servers 5.1 and 5.6 are using character set = latin1

2) I had converted the longtext to varchar(255).

3) I tried to create table with row_format=dynamic, but still getting same error.

4) Tried to create the table with ENGINE=INNODB, getting same error.

5) converted the longtext to varchar(255) using INNODB engine, getting same error.

6) Found in google to increase innodb_log_file_size, which I know it is not concerned to this, still increased to 10 GB and getting same error.

7) I am able to create the table only I create with 98 columns of type varchar(255).

Are there are any other parameters to be changed for creating this table in MyISAM ?

I am able to create this table in Linux Environment in MySQL 5.6 and 5.7. But not able to create same table in Windows with either 5.6 or 5.7. I am using Windows 64 bit. What is the difference between Linux and Windows for creating same table ?

  • Hi Ahmad, First I would like to create table in MyISAM. Even, I followed the steps as per the link and changed the innodb_log_file_size to 10GB, still it is not working. Mentioned in step 6. – Phanindra Feb 8 '16 at 10:24
