{{about|tables as column data|nested queries|Correlated subquery}}
In relational databases, a '''nested table''' is a table that is embedded within another table.
Individual elements can be inserted, updated, and deleted in a nested table. Since individual elements can be modified in a nested table, they are more flexible than an array because elements in an array can only be modified as a whole, not individually.
A nested table doesn't have a maximum size, and an arbitrary number of elements can be stored in it.
