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. This does not make sense when you want to access the same table by two different languages that have different naming conventions. Stack Overflow for Teams is a private, secure spot for you and Still Confused About Identifying vs. Non-Identifying Relationships, Table and column naming conventions when plural and singular forms are odd or the same. If you intend to ever only use one language in your services and applications, use the conventions of that language at all layers. 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. Why is my table not fully recognized by the Query pane in SSMS? 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. SELECT EmpNo, Name FROM Employee; are labeled EmpNo and Name by default. Also, in most dialects, people prefer snake_case for identifiers, although in SQL Server, people seem to prefer PascalCase or camelCase. Progress ABL/4GL allows table and field names to be created with with hyphens and start with underscore characters. Case insensitive nature of SQL supports Underscores_Scheme.

Under SQL-92 table and field names should not: Contain SQL special characters like the hyphen/dash/minus character. For example: If someone does not adhere to these conventions, the resulting code quickly looks non-idiomatic. One of Java's big strengths, in my opinion, is the fact that most naming conventions have been established by the creators of the language. But if we don't re-use the same aliases in every query, the queries start to be a bit confusing to read. @ismriv that's only a problem if you're inconsistent, if you're, I totally agree that consistency is key, but this is an old question and for people using newer database platforms like Redshift and Snowflake that default to either all upper case or lower case identifiers, I'd add that it. I tend to agree with the people who say it depends on the conventions of language you're using (e.g. I came here to see why people seem to be using camel case for SQL when it has been mostly case-insensitive historically. Auto-rename all Query columns e.g. In DB2® for z/OS®, this default name begins with COL and is followed by a number so that each column name is unique.You can change these default names on the FORM.COLUMNS panel.

I have heard it called "camel case" the most and "Pascal case" has more recently been taken up. The LIKE operator is used in a WHERE clause to search for a specified pattern in a column. See the original article here. Special characters other than underscore (_) are not supported. Pascal/camel case for table names might lead to some issues. So, once this practice is embraced, it should be applied everywhere. 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. Re: SQL: Selecting from "column names" with spaces in? Yes...yes I do. /[a-z_][a-z0-9_]*/ is really the only pattern of names that seamlessly translates between different platforms.

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. Applications of equivariant homotopy theory in chromatic homotopy theory. With the help of SQL or Structured Query Language, the Database Administrators store, update, manipulate and retrieve data in relational databases.
