Hi,

I new in database, and dont know how and when mysql allocate memory space.

In MySql Innodb how much storage memory allocation for empty field (no string inserted) vs not empty field?

Other form of my question:

When memory allocated space In MySql Innodb for varchar/text field in time of table creation or when data inserted inside field?

Thank you,

Yosef
