Description

If a table's row format is DYNAMIC or COMPRESSED and if the table's row can be too big to fit entirely on a clustered index page, then I believe that InnoDB is supposed to store variable-length columns (such as columns using VARCHAR, VARBINARY, and BLOB and TEXT types) in overflow pages. Then the clustered index only contains a 20 byte pointer to the overflow page.

https://dev.mysql.com/doc/refman/5.7/en/innodb-row-format.html

https://mariadb.com/kb/en/library/innodb-storage-formats/

However, this does not seem to work properly if you set innodb_strict_mode to ON, and if you try to create a table with a large number of small varchar columns.

For example, if you create a table that has varchar(40) columns, and if the table uses the utf8 character set, then each column requires the following storage:

40 characters/VARCHAR * 3 bytes/character (for utf8) + 1 byte/VARCHAR (for length)
= 121 bytes/VARCHAR

If we create a table with 198 of these columns, then the row size is:

198 VARCHARs * 121 bytes/VARCHAR
= 23,958 bytes

This is too large to fit in the 8126 bytes that InnoDB allocates for a row with the default innodb_page_size. However, with the DYNAMIC or COMPRESSED row formats, InnoDB should store values on overflow pages, and the clustered index should only contain a 20 byte pointer to the overflow page.

If only the primary key column is stored in the clustered index, and the rest are stored on overflow pages, then that should make the row size:

121 bytes/PK + (197 pointers * 20 byte/pointer)
= 121 bytes/PK + 3940 bytes/pointers
= 4061 bytes

This is less than the 8126 bytes that InnoDB allocates for a row with the default innodb_page_size. However, if innodb_strict_mode is ON, then InnoDB throws a "Row size too large" error if you try to create a table like this. to reproduce, run the following:

SET SESSION innodb_strict_mode=ON;

You'll see this error:

ERROR 1118 (42000): 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.

If there are only 197 columns instead of 198, then there is no error with DYNAMIC, but the error is still present with COMPRESSED.

If there are only 187 columns instead of 198, then there is also no error with COMPRESSED.

If you convert the 197 non-PK varchar(40) columns to TEXT, then you *still* get the error:
