Stored procedures used in callable and prepared statements Explore the execution of Stored Procedures using callable statement with the Informix JDBC driver Babita Sonavane and Javier Sagrera Published on September 06, Introduction In a relational database application, the main advantage of using stored procedures over single SQL statements is that the query plan or execution plan is generated when the stored procedure is created, and the same query plan is reused with every execution of the stored procedure, saving a considerable amount of resources in the database server.

When created once, they can be called by any database client, such as JDBC applications, as many times as it wants without the need for a new execution plan.

How to use stored procedures varies from one database server to another. This makes things difficult for application developers when they need to write code targeted to several DBMSes. Why use stored procedures?

Suppose we have a JDBC application that needs to efficiently repeat a sequence of tasks again and again. The database server will prepare and generate a query plan for every SQL statement sent by the application, which will consume some CPU time.

While taking performance into consideration, using simple Java methods with single SQL statements may be a bad idea. How about using a stored procedure, which is just a one-time task? Most of the business logic will reside on the stored procedure. This will help simplify the client code and will speed up the execution because the SQL statements included in the stored procedure were prepared and optimized when the stored procedure was created.

Which method you use depends on the characteristic of the stored procedure. The following table provides some guidelines for what method to use for which stored procedure type.

It acts as a placeholder for the values passed to the stored procedure. To specify a value for a parameter, you can use one of the setter methods of the IfxPreparedStatement class. The setter method you can use is determined by the data type of the IN parameter.

In addition to the value of the parameter, the setter method takes the position of the parameter in the SQL statement.5 different ways to load flat file into Oracle table.

A stored procedure is a prepared SQL code that you can save, so the code can be reused over and over again. So if you have an SQL query that you write over and over again, save it as a stored procedure, and then just call it to execute it. This "cheat sheet" covers most of the basic functionality that an Oracle DBA needs to run basic queries and perform basic tasks.

It also contains information that a PL/SQL programmer frequently uses to write stored procedures. Does anyone know of a way, or even if its possible, to call a stored procedure from within another? If so, how would you do it? Here is my test code.
