In the second part of Phil's series of articles on finding stuff such as objects, scripts, entities, metadata in SQL Server, he offers some scripts that should be handy for the developer faced with tracking down problem areas and potential weaknesses in a database.

Pretty quickly, if you are doing any serious database development, you will want to know more about a database than SSMS can tell you; there are just more things you might need to know than any one GUI can provide efficiently. Fortunately, SQL Server provides any number of ways to get at the metadata you need.

The far-more-expansive Catalog views offer just about every piece of metadata that SQL Server currently exposes to the user. This article provides various scripts for interrogating these views to get all sorts of useful information about your database that you would otherwise have to obtain slowly, click-by-wretched-click, from the sluggish SSMS Object browser.

The Catalog Views, introduced in SQL Serverprovide a more efficient and concise way of doing this, even if one loses a bit of the feel for the underlying structure. There are many more views than actual system tables and Microsoft has been assiduous in providing simple ways of getting the metadata that you want.

It is impossible to keep all the information in your head. I have a range of snippets, recipes and templates of SQL calls to get the information I want, many of which I present in this article.

Probably my most-used snippet is one of the simplest, and it gets the actual definition of all the views, procedures and functions. This is something I keep as a template. Sadly, it is impossible to get the build script for tables, along with all its associated objects, columns and indexes. If you want to get it via code, it has to be generated via SMO.

However, once you get started, there is a whole variety of things you will want to get information about what objects are associated with a given database, how many of them, who owns which objects, and so on. Details of all schema-scoped objects are stored in the sys. These additional views have added information that is specific to the particular type of object.

There are database entities that are not classed as objects. The following code, using a Catalog view, should give the same result as the previous code, but much more easily.

You can, of course use almost the same query to explore many other characteristics of the tables. We can pull of this together in a single query against the sys. By a slightly different route, we can also find out which of our tables have the most indexes on them.

Are any of them duplications? Here is a query you might use to see where the indexes might have gathered in undue numbers. I find triggers particularly troublesome as it is not always obvious that they are there. Yes, there it is. The following code should winkle out these lurking problems, and much more besides. Catalog queries are a powerful way of querying the documentation in order to find out more about the business rules governing the database structure.

There are several useful queries that you can use if you have been sensible enough to structure your documentation, such as listing out your procedures and functions, along with a brief synopsis of how they are used and why. There are a whole variety of things you will need information about as well as the details of the database objects; lists of permissions on each object and the type of permissions they represent, for example.Schemas can be useful because they allow us to take shortcuts in interpreting the vast amount of information that is available in our environment.

However, these mental frameworks also cause us to exclude pertinent information to focus instead only on things that confirm our pre-existing beliefs and ideas. Schemas can contribute to stereotypes and make it difficult to retain new information that does not conform to our established ideas about the world. The use of schemas as a basic concept was first used by a British psychologist named Frederic Bartlett as part of his learning theory. Bartlett's theory suggested that our understanding of the world is formed by a network of abstract mental structures.

According to his theory of cognitive development, children go through a series of stages of intellectual growth. He believed that people are constantly adapting to the environment as they take in new information and learn new things. As experiences happen and new information is presented, new schemas are developed and old schemas are changed or modified.

For example, a young child may first develop a schema for a horse. She knows that a horse is large, has hair, four legs, and a tail. When the little girl encounters a cow for the first time, she might initially call it a horse.

After all, it fits in with her schema for the characteristics of a horse; it is a large animal that has hair, four legs, and a tail. Once she is told that this is a different animal called a cow, she will modify her existing schema for a horse and create a new schema for a cow.

Now, let's imagine that this girl encounters a miniature horse for the first time and mistakenly identifies it as a dog. Her parents explain to her that the animal is actually a very small type of horse, so the little girl must at this time modify her existing schema for horses.

She now realizes that while some horses are very large animals, others can be very small. Through her new experiences, her existing schemas are modified and new information is learned.

While Piaget focused on childhood development, schemas are something that all people possess and continue to form and change throughout life.

Object schemas are just one type of schema that focuses on what an inanimate object is and how it works. For example, most people in industrialized nations have a schema for what a car is. Your overall schema for a car might include subcategories for different types of automobiles such as a compact car, sedan, or sports car. The processes through which schemas are adjusted or changed are known as assimilation and accommodation. Schemas tend to be easier to change during childhood but can become increasingly rigid and difficult to modify as people grow older.A list view includes a query that returns the data that is displayed in the view.

For the list of query elements, see Query schema. For the top-level elements that are used to organize a view, see List schema. In SharePoint Foundation XsltListViewWebPart object. Views can be created or modified programmatically through either the server-side or client-side object model for example, members of SPView or SPViewCollection and their related types in the Microsoft. Specialized rendering elements are used within a view to define the logic for constructing HTML.

These elements can contain numerous standard rendering elements. The following standard rendering elements are used to render HTML within the various sections of the previously listed structural or specialized rendering elements. You may also leave feedback directly on GitHub.

Email Required, but never shown.When writing queries for a database you might be new to, or one that changes often, you might want to run a quick check to find all the tables in a specific database, or the columns in the database, or to search if table or column exists. Understanding the schema and what tables are in it help to write efficient SQL and helps avoid running queries multiple times just to see if the schema name or column name is correct.

Microsoft SQL Server provides an information schema view as one of several methods for obtaining this metadata. Information schema views enable applications to work correctly although significant changes have been made to the underlying system tables.

Database Schema

We will be using a couple of the views in the information schema in order to run queries that help determine the makeup of tables in the data source. The second query will return a list of all the columns and tables in the database you are querying. With this next query you can find out whether or not there is a TABLE in the data source that matches some kind of search parameters. Now to take it a littler further, you can use this query to find out whether or not there is a COLUMN in the data source that matches some kind of search parameters.

After launching and connecting to SQL Server Management Studio, create a new login and select the database that is connected to Chartio. Learn how to check a database table for duplicate values using a simple query. SQL may be the language of data, but not everyone can understand it.

Learn about Visual SQL.Object is the default. All permissions associated with the securable will be dropped when the securable is moved to the new schema. If the owner of the securable has been explicitly set, the owner will remain unchanged.

Moving a stored procedure, function, view, or trigger will not change the schema name, if present, of the corresponding object either in the definition column of the sys. Instead, drop and re-create the object in its new schema. Moving an object such as a table or synonym will not automatically update references to that object. You must modify any objects that reference the transferred object manually. For example, if you move a table and that table is referenced in a trigger, you must modify the trigger to reflect the new schema name.

Use sys. Press F4 to open the Properties window. In the Schema box, select a new schema. Beginning with SQL Serverthe behavior of schemas changed. As a result, code that assumes that schemas are equivalent to database users may no longer return correct results. In such databases you must instead use the new catalog views. The new catalog views take into account the separation of principals and schemas that was introduced in SQL Server All permissions associated with the securable that is being transferred are dropped when it is moved.

The following example creates a type in the Production schema, and then transfers the type to the Person schema. The following example creates a table Region in the dbo schema, creates a Sales schema, and then moves the Region table from the dbo schema to the Sales schema.

The graphical interface enables you to build schemas quickly and accurately using typical GUI features. Schema View has two panes: i an upper pane for designing the structural relationships between schema components; and ii a lower pane for definitions related to the component selected in the upper pane.

There are also three entry helpers that greatly facilitate the creation of valid schemas: the Components, Details, and Facets entry helpers. By clicking the icon of a global component you can switch to the Content Model View of that global component. Note that not all global components can have a content model for example, simple types. To return to Schema Overview, click the Show Globals icon at the top left of the upper pane.

Switch to Content Model View: Available for global components that have a content model. Opens the global component's content model in Content Model View. Switches to Schema Overview.

The lower pane of Schema View see screenshot contains tabs for the definitions of Attributes, Assertions, and Identity Constraints of the component selected in the design upper pane.

To do this, toggle the respective Schema Design toolbar buttons on: i Display attributes in diagramii Display assertions in diagramand iii Display identity constraints in diagram. These settings are the attributes of the xs:schema element. From XMLSpy you can also connect to SchemaAgent in order to display components from other schemas in the GUI and to use these components in the schema being currently edited.

The Find in Schemas features enables intelligent searches in schemas, i. For example, searches may be restricted to certain component types, thus making the search more efficient.
