Hi Arshad , Thanks for writing so helpfull article. Hello everyone, I have a little problem with the code. Thanks a lot! Life Saver! Thanks again! All of these definitions collectively are called the database schema. Once a schema is defined, the database can be populated with data, the data can be retrieved or modified, and so forth. No, it is in the definition of the schema that I dislike SQL.
To begin with, I generally feel that data is best described in a declarative way. The schema of a database is unarguably data; indeed it is stored in 'system tables' in the database. But SQL is relatively hard to parse. To treat it like data, you generally have to load it into an actual SQL Server instance, then use a programming interface e.
GetSchema to query it. This seems wrong to me, and I decided to try and fix it. Those who regularly use databases will be protesting at this point that there is more to DDL than just creating the schema. Once a database is full of structure and data, it is generally not possible to throw it all away and start from scratch!
Instead it becomes necessary to manage change. SQL is a full procedural language, so it can be used to make changes based on certain conditions as well as to massage data, temporarily relax constraints, and so forth. However, the context of this project is that where I work, we have a toolchain for updating live databases from the snapshot of an empty DB, created using simple DDL. I do believe that changes in the database schema can be better represented in a declarative way, and it is a longer term goal for this project.
For the time being though, the scope of this project only goes as far as creating a new empty database from scratch. One answer is for code generation. There are several existing technologies for mapping the schema of a database into auto-generated classes, a technique known as Object Relational Mapping ORM.
It is a perfectly reasonable approach, but it does assume that the database already has the correct schema, and this is not always the case in a team environment. When working in a team, it is desirable that everybody can make changes to the database schema simultaneously, then merge their changes later.
It is also desirable to have a history of changes and who made them. In other words, I'm talking about source control. Now it is perfectly possible to have a database schema defined in SQL under source control. However, whenever one developer gets another's changes, they must remember to update their own local database instance before they update the generated code using the ORM tool.
This manual update of the database instance is only required because the ORM tool depends on it. Otherwise, it might be possible to update the database schema automatically from within the application code. As it happens, there is a project called NHibernate that is not tied to a database instance in this way. In NHibernate, the code classes are the starting point, and the database schema is generated via an XML file that describes how the classes map onto it.
The outcome is a Unicode string containing components and qualities controlled by the different modes determined in the provision with FOR XML. For example, the query result has been produced with a single XML document for the above sample data.
The query result had 5 rows in a result set, which is changed over to a solitary cell result-set. This methodology is utilized in a single-valued function to return multiple rows in a single return variable.
