Is the row size too large in MySQL?
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 am using MySQL 5.5.31 on Linux mint. No indexes. I have tried DYNAMIC format; it behaves the same way.
How to reduce the size of row in InnoDB?
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. After reading up on this, I tried to change the table to use Barracuda format by specifying ROW_FORMAT=COMPRESSED.
How many nullable columns in MySQL 5.5.32?
In MySQL 5.5.32, I can create a table with an INT PK plus up to 186 nullable TEXT or BLOB columns, but if I try to define 187 or more TEXT or BLOB columns, I get the same error as OP.

Is there a limit to the number of columns in MySQL?
MySQL has hard limit of 4096 columns per table, but the effective maximum may be less for a given table. The exact column limit depends on several factors: The maximum row size for a table constrains the number (and possibly size) of columns because the total length of all columns cannot exceed this size.
