Running a RDL/RDLC (SQL Report) in ASP. NET without SSRSSSRS and Report Builder (or the old BIDS from 2. ASP. NET project very nicely. You might be planning to write some new reports and you are trying to decide on which technology to use or you might have several SSRS reports that were already made, earlier, and you want to run them from your ASP. NET site. There are many good articles on Code. Project that show how to use an RDLC file to run a report, either from ASP. A database is an organized collection of data. It is the collection of schemas, tables, queries, reports, views, and other objects. The data are typically organized.
NET or Win. Forms, etc. After reading them, it would seem that your choices are: Put a report into SSRS and use the Report. Viewer control to call SSRS to run your report. Add the . RDL or . RDLC file into your project and create some objects to house the data so the report has an interface to the database. I wanted a third choice: Just run it like SSRS does, but without installing the SSRS server. I’m talking bare- minimum footprint. I just want to pass the name of the . RDL or . RDLC file to an ASPX page and have it run. That is how SSRS does it. I should be able to do that too. This is an implementation of the third choice. Prerequisites. To run this, you still need to install the reporting run- time. You can get it from MSDN here. I had some old reports, which were made with the old Business Intelligence Development Studio (2. ![]() Recent changes in DB2 for z/OS Logging Michigan DB2 Users Group May 21, 2014 Ken McDonald, BMC Software. SOAP codifies the existing practice of using XML and HTTP as a. I have been programming for 30 years(22 professionally). I mostly work with the Microsoft product stack (.NET, SQL Server, IIS, ASP.NET, Dynamics, TFS, etc) however. I also have some new reports which were made with Report. Builder (built- into SSRS web). This solution will work with either. Strategy. A . RDLC file is all XML. If you open it with Notepad and inspect the contents, you can see that the XML describes the display/design, but it also contains several other useful characteristics. One of them is the query (to get the data) for the report. My strategy is to extract the database query, set up any parameters, run the query, store the results in a Data. Table(s) and feed it into the report. My goal is to run my reports from a generic page and pass the report name and any query parameters via the URL Query. String, like this../View. Report=Example. rdlc& Start. Date=1/1/2. 01. 2& End. Date=1. 2/3. 1/2. For simplicity, I will just use the same DB connection string that is used by the rest of the app, but I will wrap it in a local factory method, for maintainability. Using the Code. Starting with the End in Mind. This is where I started. I borrowed from other articles on Code. Project (please see the credits, near the end of the article). The examples worked great, but didn’t have a means to use the query that was embedded in the report. In the code- block (below), you can see that I created a class called Report (namespace RDL) to encapsulate the RDLC’s content/structure. My RDL. Report class also contains a factory method to help with converting the XML into objects. Show. Report(). . Now, let’s look at the parts that get the data. Get the Query from the RDLC File. Inside the . RDLC file, the XML for the query looks like this (after you remove everything else): < Report> < Data. Sets> < Data. Set. Name=& rdquo; Irrelevant. To. This. Example& rdquo; > < Query> < Data. Source. Name> Data. Table. Name< /Data. Source. Name> < Command. Text> SELECT * FROM sys. Tables< /Command. Text> < /Query> < /Data. Set> < /Data. Sets> < /Report> On my first attempt, I used XPath to extract the query from the XML (inside of the RDLC file). It worked for simple queries. However, I realized that things got messy if the query had any parameters (or for Stored Procedures, etc.). On my second attempt, I took a different approach. I realized that the code would be much easier if I deserialized the XML into a stack of objects. It sounds complicated and scary, but once you see it, you will realize how incredibly simple XML Serialization/Deserialization can be. The (simplified) classes that match this XML look like this. It makes it simple to serialize or deserialize any object to XML or vice- versa. I had to add several more classes for deserialization. For brevity, I will include them in the downloaded code but save you the headache of reading the code here. They are very simple (boring) classes that match the structure of the XML, just like the serialization classes above. Refactored. The rest of this code started out in utility classes. After looking at them, I realized that it would be more OO pure if I encapsulated the utility code within the serialization classes as methods rather than as external helper utility functions. It makes the serialization classes seem more complicated. That is why, for this article, I started by describing the original classes (above) in their simplest form. Report Parameters/Query Parameters. Unfortunately, in the RDLC files, the query block defines its parameters, but doesn’t define types for them. The DB will choke on types that don’t cast easily, such as: Date. Time, Numeric, and Integer. Luckily, the parameter types are defined in a separate part of the RDLC’s XML. I just need to copy those into the query parameter definitions. Serialize / De- Serialize Java Object From Database. In recent days generalization have become popular in software development. You build a common platform and generate applications out of it to reduce the cost. In such applications an activity that will be frequently performed is serializing java objects to database. There are many fancy tools and framework available to do this. Before using all of those, you need to understand the low level details of serializing a java object to database. In older days before the advent of JDBC 3. Stream the object to a Byte. Array. Output. Stream via an Object. Output. Stream. Convert the Byte. Array. Output. Stream to a byte array. Call the set. Bytes method on the prepared statement. Now you can use Object type support from jdbc to store the object into database. There are some key factors before performing serialization. Datatype to be used to persist the object. Also know some fundamentals of serialization. I have given a sample java source code below to serialize and de- serialize java object to mysql database. In that, I have commented a line. Object object = rs. Object(1); Enable this line and comment the following 4 lines and execute and see the result. You will learn one more point. To de- serialize a java object from database: Read the byte array and put it into a Byte. Array. Input. Stream. Pass that to an Object. Input. Stream Then read the object. Sample Java Source Code – Serialize to DBBefore you run the following example, you need to create a database and a table in it. You may use the database of your choice with tweaks to the connection strings..
