PLSQL functions enable us to modularise and encapsulate our business logic, following generalised programming best practices. General SQL Scripts. Sample SQL matrix report Lookup Oracle error messages Display Database version, installed options and port string Who am I script. Dynamic SQL and PLSQL has been supported in Oracle for many versions. Before Oracle 8i, we used the low level DBMSSQL package and more recently we have used Native Dynamic SQL to parse, bind and execute dynamic statements. Method 4 dynamic SQL, however, has never been truly possible natively in Oracle i. PLSQL. For example, consider the following pseudo statements. FROM somepackage. How do we deal with any dynamic query you likeSome Common Unicode Problems and Solutions using Perl DBDODBC and MS SQL Server Introduction. In this article, I have tried to collect some useful information to. Pl Sql Developer 8 Full Version' title='Pl Sql Developer 8 Full Version' />What is it What does it look like How do we fetch it How do we display it We will answer these questions in this article and demonstrate how to fetch data dynamically using the following SQL statement. Pl Sql Developer 8 Full Version' title='Pl Sql Developer 8 Full Version' />FROM TABLE dlapkg. SELECT statement. A Method 4 scenario is one in which any dynamic statement can be programmatically understood, executed and fetched without knowing any of the structures involved at the time of compilation. Imagine the various IDEs and middle tier applications we use to query data from Oracle. Whether they be sqlplus, TOAD, SQL Developer or home grown applications in Java, PHP, C etc, one thing that these tools and languages have in common is the ability to take a cursor or ref cursor and fully display its associated resultset, regardless of the structure of the SQL statement we execute. These tools and languages are able to understand the record structures that are being returned. This is possible due to the various protocols used to access Oracle OCI, OCCI, JDBC, ODBC etc. Now consider how we might handle Method 4 dynamic SQL in PLSQL. We can easily prepare and parse a dynamic statement. We can also programmatically handle bind variables without knowing how many we are going to bind if we use DBMSSQL. We can execute this statement without needing to know its form and structure. But what do we fetch the returning data into In PLSQL we regularly fetch into variables, records and collections of records, but regardless of which variable type we use, we need to know its structure at compile time. For this reason, true Method 4 dynamic SQL is not possible in native, static PLSQL. My coworkers are asking me to keep a full history of all SQL queries run against our production database Oracle. Tuning PLSQL Applications for Performance. This chapter explains how to write efficient new PLSQL code and speed up existing PLSQL code. Topics. There are ways of achieving this however, but they are complicated and involve DBMSSQL describe APIs and PLSQL to build and execute a dynamic anonymous PLSQL block. For an example of this, see this oracle developer. With the Oracle Data Cartridge framework, we have an alternative method of achieving Method 4 scenarios for dynamic statements that return datasets. One of the lesser known features of Oracle is the Data Cartridge framework which, according to the documentation, provides the mechanism for extending the capabilities of the Oracle server. What this actually means is that we can create a set of processing rules inside one or more object types and plug them into the Oracle server to use in various scenarios. One of these scenarios comprises pipelined functions that return instances of ANYDATASET a generic type introduced in Oracle 9i. For this, Oracle provides the development framework for us to create a pipelined function, implemented as a Data Cartridge, that will return any record structure we request of it. In other words, we can exploit the Data Cartridge framework and combine it with pipelined functions to create a true Method 4 engine inside the database, as we will see in this article. For readers who wish to familiarise themselves with the Oracle Data Cartridge framework, this oracle developer. Lego Batman 2 Dc Superheroes Pc Dlc Ps3'>Lego Batman 2 Dc Superheroes Pc Dlc Ps3. Many readers will be familiar with Tom Kytes STRAGG function which is built on the same principles and framework. Note that the techniques we will use below will be more complicated than aggregate function implementations, so a solid grounding in the principles of building Data Cartridges is advised. We are going to use an existing oracle developer. Data Cartridge and pipelined ANYDATASET functions to demonstrate native Method 4 capabilities. This application is named not particularly creatively the Dictionary Long Application. It is built as a Data Cartridge with a single purpose to query any dictionary view with LONG columns and return CLOBs instead. Examples are DBAVIEWS and DBATABPARTITIONS, where we often wish to search inside the LONG columns but cannot due to their inflexibility. As CLOBs, these columns are as SQL friendly as a regular VARCHAR2 column since Oracle 9i of course. The Dictionary Long Application we will call it DLA from now on will accept any dynamic SQL statement and return the relevant dataset, as though we were querying statically in sqlplus. As an aside, the DLA should technically work from all versions of 1. However, due to a bug in Oracles CLOB handling, the version of the DLA we will see in this article will only work from 1. Release 2 1. 0. 2 onwards. For 9i and 1. 0g Release 1 1. Pl Sql Developer 8 Full Version' title='Pl Sql Developer 8 Full Version' />DLA available in the download at the end of this article. A native Data Cartridge of the type we require is built of two components an object type that implements the rules of the application using well defined APIs contained in Oracles Data Cartridge development framework anda PLSQL function that declares itself as implemented by the object type. The well defined APIs referenced above are built in static and member methods, prefixed with ODCI. Some of these methods are mandatory and some are optional based on functionality we may or may not wish to implement. There are several types of Data Cartridge and each varies in the built in methods they need to include, but we will be using the ODCITablestatic and member functions. In addition to an object type based on ODCITablefunctions, we will also create a pipelined function. Unlike a regular pipelined function, this function will be fully implemented by the object type and not created in PLSQL. We will see the details later in this article. With reference to the DLA, we will demonstrate how to build a Data Cartridge for a Method 4 dynamic SQL application. The implementing type for the DLA is quite complicated, but remember that in any Method 4 application we are trying to develop a program that can parse, describe, bind and fetch data for any SQL statement. The added twist with the DLA is that it converts LONGs to CLOBs, but this doesnt detract from its Method 4 capability. Swf Catcher Crack. We will build the implementing type for the DLA in small stages, breaking to describe certain elements of the syntax and logic. We will begin with the type specification, which provides a good overview of the methods we will need to implement. The implementing type is named DLAOT and is defined as follows. SQL CREATE TYPE dlaot AS OBJECT. ANYTYPE lt transient record type. STATIC FUNCTION ODCITable. Describe. 6 rtype OUT ANYTYPE. IN VARCHAR2. 8 RETURN NUMBER. STATIC FUNCTION ODCITable. Prepare. 1. 1 sctx OUT dlaot. IN sys. ODCITab. Func. Info. 1. 3 stmt IN VARCHAR2. RETURN NUMBER. 1. STATIC FUNCTION ODCITable. Start. 1. 7 sctx IN OUT dlaot. IN VARCHAR2. 1. RETURN NUMBER. MEMBER FUNCTION ODCITable. Fetch. 2. 2 SELF IN OUT dlaot. IN NUMBER. 2. 4 rws OUT ANYDATASET. Can I Buy A Uk Driving License there. RETURN NUMBER. 2. MEMBER FUNCTION ODCITable. Close. 2. 8 SELF IN dlaot. RETURN NUMBER. The names of the static and member functions provide a good summary of Method 4 requirements. The most interesting method is the ODCITable. Fetch function because this is the area where PLSQL traditionally breaks down in Method 4 scenarios. Note how this function is passing out an instance of ANYDATASET i.
