In the performance optimization analysis of Java, JProfiler can be used to analyze information such as CPU consumption, Memory usage, and Thread usage during JVM running. The stored procedures and functions of Oracle called in Java code can also output the call time, number of calls, and other information. However, JProfiler won't be able to cope with the internal performance of the process and function. In an optimization practice, I encountered the above situation. The storage process is a per

is a simple example! There is no practical value. Generally, databases involve adding, deleting, modifying, and querying data:Ultra-simple query:Create or replace procedure pro_lab (P_id s_emp.id % Type // p_id is the form parameter of pro_lab.) IsV_fname s_emp.first_name % type;BeginSelect first_nameInto v_fname// Into assigns the query result to the variable v_fname.From s_empWhere id = p_id;Dbms_output.put_line ('hello, '| v_fname );End; // Call p

I am not a dedicated developer, but the stored procedure is a very important knowledge, in order to be able to very good memory, the basic knowledge is now summed up. The stored procedure can realize the full sharing of the code and improve the system performance.A review of basic knowledgeIf you often use specific operations, which can be considered based on these operational processes, simplifying develop
