Note that Oracle is committed to continuing support and development of PL/SQL - there is no reason to convert PL/SQL into Java for future compatibility. Also, PL/SQL and Java are fully interoperable: you can call PL/SQL stored procedures from Java using JDBC or SQLJ and vice versa. There are third-party products (for example from Quintessence Systems http://www.in2j.com) that provide for an automated migration from PL/SQL to Java. See similar questions...

Space: The overhead of running Java in a database session is a couple of tens of kBytes per session in addition to any memory that is used directly by the Java program. Time: Every connection (database session) that you establish, requires a one-time startup time for the JavaVM (and for the SQLJ runtime, see also Performance of Java and SQLJ in Stored Procedures). See similar questions...

Yes. The DataDirect Connect Series Oracle drivers fully support returning result sets (including multiple result sets) generated from PL/SQL stored procedures against 7, 8, 8i, 9i, and 10g servers. This implementation is: Flexible-You can call any stored procedure without worrying about data integrity or the size of result sets. See similar questions...

Although SQL VARRAYs have been supported by SQLJ and JDBC, PL/SQL index tables are not supported by SQLJ or by JDBC at this time. You would have to use a PL/SQL stored procedure wrapper to convert a PL/SQL index table to of from a VARRAY or nested table to access the argument from Java. With Oracle 8i, new object types and new collection types (VARRAYs and nested tables) are available in JDBC. See similar questions...

Unfortunately, the official specifications are not freely available (ANSI makes them available for purchase). However, there are books - such as SQL-99 Complete, Really by Peter Gulutzan and Trudy Pelzer - which give a comprehensive overview of the standard, including coverage of stored procedures.

Yes, both the Oracle JDBC OCI Driver and the Thin JDBC Driver support execution of PL/SQL stored procedures and anonymous blocks. and anonymous blocks. They support both SQL92 escape syntax and Oracle escape syntax. The following PL/SQL calls are available from both of Oracle JDBC Drivers: SQL92 Syntax CallableStatement cs1 = conn.prepareCall ("{call proc (?,?)}"); CallableStatement cs2 = conn.prepareCall ("{? = call func (?,?)}"); Oracle Syntax CallableStatement cs1 = conn.

Both PL/SQL and Java can be used to create Oracle stored procedures and triggers. This often leads to questions like "Which of the two is the best?" and "Will Oracle ever desupport PL/SQL in favour of Java?". Many Oracle applications are based on PL/SQL and it would be difficult of Oracle to ever desupport PL/SQL. In fact, all indications are that PL/SQL still has a bright future ahead of it. Many enhancements are still being made to PL/SQL. See similar questions...

In the proc table of the mysql system database. However, you should not access the tables in the system database directly. Instead, use SHOW CREATE FUNCTION to obtain information about stored functions, and SHOW CREATE PROCEDURE to obtain information about stored procedures. See Section 13.5.4.8, "SHOW CREATE PROCEDURE and SHOW CREATE FUNCTION Syntax", for more information about these statements. You can also query the ROUTINES table in the INFORMATION_SCHEMA database - see Section 22. See similar questions...

PL/SQL lets you issue a query and return a result set using a cursor variable, also known as a REF CURSOR. See "Using Cursor Variables (REF CURSORs)". See similar questions...

We don't use stored procedures since they will result in a non-portable application. Our design allows, however, for stored procedures to be added elegantly--all you need to do is to provide an alternate Data Access Object that plugs into the application architecture and makes stored procedure calls. These are essentially a performance optimization that are particular to a specific application and its deployment environment. See similar questions...

Most likely you're trying to debug on a version of VS that doesn't support SQL debugging. You need Visual Studio Professional Edition or higher. Credentials used to run VS and to make connection to SQL Server must have SA role e.g. part of Administrators group on SQL Server box. Go to https://connect.microsoft.com/site/sitehome.aspx?SiteID=210&wa=wsignin1.0 and click on Submit Feedback and follow steps to file a bug/suggestion against VS debugger. See similar questions...

By default, you put an exception handler at the end of a subprogram to handle exceptions that are raised anywhere inside the subprogram. To continue executing from the spot where an exception happens, enclose the code that might raise an exception inside another BEGIN-END block with its own exception handler. For example, you might put separate BEGIN-END blocks around groups of SQL statements that might raise NO_DATA_FOUND, or around arithmetic operations that might raise DIVIDE_BY_ZERO.

The DriverManager class is a core part of the java.sql package for Java database connectivity, it provides a registry of JDBC drivers that are loaded and available for use, and methods to get database connections using those drivers. The JDBC specification requires implementations of the java.sql.Driver interface to register themselves with the DriverManager method registerDriver(Driver) when their class is loaded through the Class.forName(String) method.
