Question

I just setup debian 8.3 on a VM and installed xampp after this Tutorial. Everything is working, until I tried to create a new table:

create table testtable
(         


        

Answer 1

For a permanent solution, pls add following in your mariadb My.INI file-

## Innodb settings to bypass error of max size 737
innodb-file-format=barracuda
innodb-file-per-table=ON
innodb-large-prefix=ON
## Above 3 didnot work so i added below
innodb_default_row_format = 'DYNAMIC'

I was using 10.1.38

Answer 2

Between 5.6.3 and 5.7.7 (that is if you are running MySQL 5.6 or MariaDB 10.0), there are 4 steps:

• SET GLOBAL innodb_file_format=Barracuda;
• SET GLOBAL innodb_file_per_table=ON;
• ROW_FORMAT=DYNAMIC; -- or COMPRESSED (goes on end of CREATE)
• innodb_large_prefix=1

Note

SELECT * FROM information_schema.INNODB_SYS_TABLESPACES;

will provide the file_format and row_format. Some other I_S tables provide clues of file_per_table.

Answer 3

I'm using Mysql 5.6.17 with WAMP Server I solved the problem by editing the my.ini file Find the category [mysqld] there add the following instructions

[mysqld]
innodb_file_format = Barracuda
innodb_large_prefix = 1
innodb_file_per_table = ON

Don't forget to save the changes and restart all services.

Answer 4

Go to your xampp and add this query:

`mysql>` set global innodb_file_format = `BARRACUDA`;
`mysql>` set global innodb_large_prefix = `ON`;

Answer 5

mysql> set global innodb_file_format = `BARRACUDA`;
mysql> set global innodb_large_prefix = `ON`;
