One of the possible ways to pass a collection of values to a stored procedure is to use Associative Array (also known as Index-By Tables). Since all parameters should be arrays of equal length, it may not be the right choice if not all parameters are arrays. The ability of using SQL to operate on Associative Arrays or PL/SQL tables as they were known when I started working as a Database Developer is … ASSOCIATIVE ARRAYS can only exist in PL/SQL memory structures. Of course, they behave nothing like a table because they are essentially an array structure, certainly in terms of how we interact with them. In 18c Oracle has introduced qualified expressions that can also be used to initialize an associative array. Its a nice feature unless you are trying to use the data contained within that associative array in a sql query.

Using the information derived from above questions we can define Associative Arrays as one-dimensional, homogenous collection which stores data into key-value pair. Associative arrays are used to store key value pairs. In earlier versions of Oracle, PL/SQL tables could only be indexed by BINARY INTEGERs, in Oracle 9i Release 2 and above they can be indexed (associated) with BINARY INTEGER or VARCHAR2 constants or variables. PL/SQL Associative Array support BINARY_INTEGER, PLS_INTEGER, POSITIVE, NATURAL, SIGNTYPE or VARCHAR2 as index datatype. You simply use the array variable. Associative arrays or index by tables are set of key value pairs. In terms of structure, both the index-by table and nested tables are similar and have subscript to access the elements. While a cell is identified by an index of number or string type, it can hold a value of a scalar data type or user-defined composite type. These are a few core questions which you can expect in your exam or interview. Unlike Nested Tables and VARRAYs, indexing in Associative array is Explicit. This explicit indication is known as a typemark. A relatively small search table that can be built in memory every time you call a subroutine or initialize a package that announces it. When you reference an element of Associative Arrays that uses a key based on VARCHAR2, you can use other types such as DATE or TIMESTAMP if they can be converted to VARCHAR2 using the TO_CHAR function.
