Presents expert tips and best practices drawn from extensive experience in real customer environments. The authors offer up-to-the-minute coverage, best practices, and tips for building basic SQL procedures, writing flow-of-control statements, creating cursors, handling conditions, and much more. Along the way, they illuminate advanced features ranging from stored procedures and triggers to user-defined functions.

Coverage includes. The matching rules will first search for a public definition, and then an owner qualified procedure name. The following are special considerations for using the procedural feature with the gateway:. Both linkage conventions require that the parameters that are passed to and from the DB2 stored procedure cannot be null. By default, all stored procedures and functions do not return a result set to the user. The gateway returns the following information to Heterogeneous Services during procedure description:.

One out argument of type ref cursor corresponding to the first result set returned by the stored procedure. The last result set returned is the out argument from the procedure. Result sets returned by a remote stored procedure have to be retrieved in the order in which they were placed on the wire. On execution of a stored procedure, all result sets returned by a previously executed stored procedure will be closed, regardless of whether the data has been completely retrieved or not.

A connection to the gateway is established through a database link when it is first used in an Oracle database session. In this context, a connection refers to both the connection between the Oracle database and the gateway and to the DRDA network connection between the gateway and the target DRDA database.

The connection remains established until the Oracle database session ends. Another session or user can access the same database link and get a distinct connection to the gateway and DRDA database. One of the most important features of the Oracle Database Gateways products is providing SQL transparency to the user and to the application programmer. Foreign SQL constructs can be categorized into four areas:.

These SQL constructs are forwarded unmodified.

All of the compatible functions are column functions. Translated functions have the same meaning but different names between the Oracle database and the DRDA database. But all applications must use the Oracle function name. Oracle database changes the function name before sending it to the DRDA database, in a manner that is transparent to your application. Oracle database applies the function.

Oracle database can compensate for a missing or incompatible function by automatically excluding the incompatible SQL construct from the SQL request that is forwarded to the DRDA database.

Oracle database then retrieves the necessary data from the DRDA database and applies the function. This process is known as post-processing. However when a DRDA database does not support a function that is represented in the computation, the gateway changes that function. Because the database does not support many of the COS functions, the gateway changes the query to the following:. After the data is moved to the Oracle database, the COS function is performed.

If you are performing operations on large amounts of data that are stored in a DRDA database, then keep in mind that some functions require post-processing. Some SQL functions that are normally compensated may also be overridden, through the Native Semantics facility. Refer to "Native Semantics" for more information.

In this case, the Oracle database compensates for the missing or incompatible functionality by post-processing the DRDA database data with Oracle database functionality. This feature provides maximum transparency, but may impact performance. In addition, new versions of a particular DRDA database may implement previously unsupported functions or capabilities, or they may change the supported semantics as to make them more compatible with Oracle database functions.

Some of DRDA servers also provide support for user-defined functions. Native Semantics provides a method of enabling specific capabilities to be processed natively by the DRDA server. Various considerations must be taken into account when enabling the Native Semantic feature of a particular function because Native Semantics has advantages and disadvantages, which are typically a trade-off between transparency and performance.

One such consideration is the transparency of data coercions. Oracle database provides coercion implicit data conversion for many SQL functions. This means that if the supplied value for a particular function is not correct, then Oracle database will coerce the value change it to the correct value type before processing it. However, with the Native Semantic feature enabled, the value, exactly as provided, will be passed to the DRDA server for processing.

In many cases, the DRDA server will not be able to coerce the value to the correct type and will generate an error. Another consideration involves the compatibility of parameters to a particular SQL function. Another consideration is that the processing of a function at the DRDA server may not be desirable due to resource constraints in that environment.

They can be enabled turned ON as an option:. If you need to minimize the use of expensive resources, then you should choose the settings of these functions so that the processing is performed with cheaper resource.

The above listed functions can also be disabled. This means that these clauses are passed unchanged to the DRDA server for processing. To move data between applications and the database, the gateway binds data values from a host variable or literal of a specific data type to a data type understood by the database.
