After Nested Table and VARRAYs, Associative Array is the third type of collection which is widely used by developers. As said above Associative array is non-persistent type of collection thus it cannot be created as standalone database object hence cannot be reused like the rest of the other collections. aa_var('two') := 2; Prior to 12.1, this was only possible with schema-level nested table and varray types.

The keys are unique and are used to get the values from the array. n PLS_INTEGER := 5; -- number of multiples to sum for display Original answer upto 12c. As a non-persistent collection, it cannot be stored in the database, but they are available within a PL/SQL block only. ASSOCIATIVE ARRAYS can only exist in PL/SQL memory structures. If the structure is heterogeneous, where each element might be a different data type, and if the keys of your array are all text analogous to attribute names, then a SQL tuple/row is the most direct analogy, so use some ROW type with one attribute per associative array element. Thanks & have a great day!

PLSQL tables are composite datatypes. Unlike Nested Tables and VARRAYs, indexing in Associative array is Explicit. As you can see in order to insert the data into the associative array you first have to write the name of array variable followed by the array’s subscript and then the data for your array. Again you don’t need to write the UPDATE DML for updating the values. The population of RaiCenter is equal to 750000 inhabitants.
