Example of PLSQL procedure Let us learn the implementation of the PL/ SQL stored procedures with the help of some examples – Let us look at the example that demonstrates how the cursor can be used in PL/ SQL to retrieve the information about a particular entry in the table. Consider that...
PL/SQL stored procedure with at least one OUT SYS_REFCURSOR said procedure accommodates inputs to shape the SQL behind the cursor paging logic ability to pass values to specify where we want to start and how many rows to grab provide link(s) to move about the pages ...
For example, a CREATE TABLE statement causes many updates to various data dictionary tables to record the new table and columns. Recursive calls are made for those recursive cursors; one cursor can run several recursive calls. These recursive cursors also use shared SQL areas....
