Stack Overflow for Teams is a private, secure spot for you and But I'd add another consideration: you may find that there are other factors when you move from a class in your app to a table in your database: the database object has views, triggers, stored procs, indexes, constraints, etc - that also need names.

What's the best practice for primary keys in tables? I came to conclusion that if DBs from different vendors are used for one project there are two best ways: The reason is that some database will convert all characters to uppercase and some to lowercase. I had one more question, how to handle the below scenario: Informatica target instance has a different column name wrt the SQL target table column name. What's the most efficient way to safely convert from Datetime2 back to Datetime.

The standard approach to aliasing things I've found very useful is to use this simple algorithm that produces four-letter aliases for every table. But if we don't re-use the same aliases in every query, the queries start to be a bit confusing to read. As part of the product installation guide, this allows you to document all such tables as installation tables that should not be touched."

Most SQL databases support only a 3-4 layered set of namespaces: In any case, there is no such concept as package ("schema") hierarchies as there is in languages like Java, which makes namespacing in SQL quite tricky. Progress ABL/4GL allows table and field names to be created with with hyphens and start with underscore characters. Start with non-alphabetic characters like the underscore. Then you can easily translate (even automatically) names between environments. This is easy to work around, but a tedious problem to think of all the time. Why is my table not fully recognized by the Query pane in SSMS? Queries with mixedCase column names, such as profileURI, or upper case column names do not work. We could just not use aliases and always fully qualify all identifiers: But that quickly turns out to be verbose, especially with longer table names, so also not very readable. Easy to understand, to prevent confusions. Nine of the Most Common Mistakes in Database Design.

This Frequently asked Questions explains how to find the list of Column names in a Table using sys.columns. becomes, If the name contains three or more underscores, take the first letter of each word, If a new abbreviation causes a conflict with the existing ones, make a pragmatic choice, What table a given column originates from, If that column has an index you can use (on a query against the view! Is there a way to separate geometry that shares verts/edges? @SinthiaV I don't know about others but in our case since we're using a JS ORM (regrettably) the options were 1) break convention by using camelCase in the db 2) break convention by using snake_case in JS 3) map camelCase in JS to snake_case in db. A problem that can easily happen when writing stored procedures: As can be seen above, both the CUSTOMER.ID column as well as the GET_NAME.ID parameter could be resolved by the unqualified ID expression. If your DB engine can't support the SQL standard, that's its problem. So, if you have myTable it will become MYTABLE or mytable when you will work with DB. I typically use PascalCase and the entities are singular: It mimics the naming conventions for classes in my application keeping everything pretty neat, clean, consistent, and easy to understand for everybody. A few weeks ago, I posted an article titled \"Lightning-Fast Access Control Lists in C#\", in which I described a solution for storing and querying permissions in a way that is database-schema agnostic. In SQL, this is a bit different. Making statements based on opinion; back them up with references or personal experience. Why does HTTPS not support non-repudiation? Java), they are less easy to qualify properly. SQL is different. In MySQL for example, I don't suggest using CamelCase since not all platforms are case sensitive.

In other words, yes, well done, you've identified some consistent schemes. If you want readability (which is of huge importance) you better use the naming conventions for each language. Lowercase alpha-numeric+underscore will always work consistently. 0. Unlike with hungarian notation itself, where the data type is encoded in the name, in this case, we might encode some other piece of information in the name. why does this happen? To learn more, see our tips on writing great answers. What's more, you can use these abbreviations everywhere, not just when writing joins: But also when aliasing columns in views or derived tables: This becomes invaluable when your queries become more complex (say, 20-30 joins) and you start projecting tons of columns in a library of views that select from other views that select from other views. I have a query that returns over a hundred columns. -- Query to Get Column Names From Table in SQL Server USE [SQL Tutorial] GO SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = N'NewCustomers' OUTPUT.

So, in this article let us understand how to rename a column name in SQL. Underscore as a table name in MySQL is possible? Get on with it! These are my five cents.

It's easy to keep consistent, and you can also easily recognize things like: I think that if you work with views extensively (I've worked with schemas of 1000+ views in the past), then such a naming convention is almost mandatory. Being consistent is far more important than what particular scheme you use. Just grab your columns names from: select column_name from information_schema.columns Sure, as someone else in the thread, AS will allow you to alias/change output on a select/query, but that doesn’t really do a whole lot to change existing structures (sp_rename comes in for that).

A schema should exist completely independently from a user), it may be useful to encode a schema in the object name: Besides, when using views for security and access control, one might have additional prefixes or suffixes to denote the style of view: This list is obviously incomplete. When you're using a code generator like jOOQ's, the generated column names on views will already include the table name as a prefix, so you can easily "see" what you're querying. The purpose for such a simple abstraction layer is that it can be expanded when necessary to allow changes in one environment to avoid impacting the other.

I'm a little foggy this morning. These may be identified as the table name with just a suffix of '_v' or you could put them in a different schema. July/August 2013. Also, on a side note to the current naming scheme PascalCase is better, specially if you don't use Aliases for the SQL Queries. But given the limitations of some SQL dialects, or the fact that after joining, two names may easily conflict, I've found the above two tools very useful in the past: 1) Prefixing identifiers with a hint about their object types, 2) Establishing a standard for aliasing tables, and always alias column names accordingly. With the help of SQL or Structured Query Language, the Database Administrators store, update, manipulate and retrieve data in relational databases. The rules for naming database objects (such as tables, columns, views, and database procedures) are as follows: •Names can contain only alphanumeric characters and must begin with an alphabetic character or an underscore (_). Published at DZone with permission of Lukas Eder, DZone MVB.
