This patch adds support for associative arrays in stored procedures
for sql_mode=ORACLE.
The syntax follows Oracle's PL/SQL syntax for associative arrays -
TYPE assoc_array_t IS TABLE OF VARCHAR2(100) INDEX BY INTEGER;
or
TYPE assoc_array_t IS TABLE OF record_t INDEX BY VARCHAR2(100);
where record_t is a record type.
The following functions were added for associative arrays:
- COUNT - Retrieve the number of elements within the arra
- EXISTS - Check whether given key exists in the array
- FIRST - Retrieve the first key in the array
- LAST - Retrieve the last key in the array
- PRIOR - Retrieve the key before the given key
- NEXT - Retrieve the key after the given key
- DELETE - Remove the element with the given key or remove all elements
if no key is given
The arrays/elements can be initialized with the following methods:
- Constructor
i.e. array:= assoc_array_t('key1'=>1, 'key2'=>2, 'key3'=>3)
- Assignment
i.e. array(key):= record_t(1, 2)
- SELECT INTO
i.e. SELECT x INTO array(key)
TODOs:
- Nested tables are not supported yet.
i.e. TYPE assoc_array_t IS TABLE OF other_assoc_array_t INDEX BY INTEGER;
- Associative arrays comparisons are not supported yet.
