Ask TOM "Indexing array" I mean -- what should the "index" in the array be? With an index by binary_integer -- it is logical that row 1 goes into index 1, row 2 into index 2 and so on. With an index by varchar2 -- when you fetch organization name -- what INDEX should be used????? Look at your example and tell me what would/should be returned by t_org_arr( 'Baker Rost' ) PLS INTEGER - Oracle FAQ PLS_INTEGER is a PL/SQL data type used for storing signed integers. PLS_INTEGER is defined in the STANDARD package as a subtype (or rather a synonym) of BINARY_INTEGER. Variables declared as PLS_INTEGER can be assigned values between -2**31 to 2**31-1 (-2,147,483,648 to 2,147,483,647)..

Another difference between pls_integer and binary_integer is that when calculations involving a pls_integer overflow the PL/SQL engine will raise a run time exception. But, calculations involving a binary_integer will not raise an exception even if there is an overflow. Oracle Associative Array and Array by BINARY_INTEGER
An associative array must be declared in a package separately and not in the same PL/SQL unit for it to use the TABLE function. In the below example, the package PKG_AA is created with an associative array having a record as its element’s data type and PLS_INTEGER as its index’s data type.

Prior to Oracle9i Database Release 2, BINARY_INTEGER was the only indexing datatype allowed for associative arrays (aka, index-by tables), General. Array Syntax, TYPE type_name IS TABLE OF element_type [NOT NULL] INDEX BY [BINARY_INTEGER | PLS_INTEGER | VARCHAR2(size_limit)]; INDEX BY: Specifies that the associative array is to be indexed by one of the data types introduced by this clause. BINARY INTEGER: Integer numeric data. Syntax "index => values", separated by commas, define index and values. index may be of type string or integer. When index is omitted, an integer index is Unadorned integer literals (including hex, octal and binary numbers) yield integers. index of the first occurrence of x in s (at or after index i and before index j).
