pl sql programs examples

and Testing This problem is more intuitive and confusing, but there are still conceptual barriers after careful analysis. This is the compile time and run time of the program. When we compile a PL/SQL program, both procedure and package have a compile action. After the compile operation is successful, we can execute the program exec. In compile, the work is similar to that in any language compiler. Most of

Abstract: In the PLSQL development process, the use of SQL and PLSQL can meet most of the requirements, but in some special circumstances, using standard SQL statements or DML statements in PLSQL cannot meet your needs. for example, dynamic table creation or an uncertain operation must be performed dynamically. This requires dynamic SQL. This article describes PL

Using these tools, you can recompile all illegal objects, search for texts in the database, import or export tables, generate test data, export text files, monitor dbms_alert and dbms_pipe events, and view session information.Authorization-in most development environments, you do not want all databases to have all the functions of PL/SQL developer.

In fact, this view shows the size of the original, parsed, and compiled code. Despite being diligently used by compilers and runtime, you can also find large programs in the environment.[USER_OBJECTS]: contains information about all objects in one mode.
