I am trying to import a 15 MB mySQL DB in phpMyAdmin but I get an error. How can I fix this?

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
