  2. mysql - What is a table prefix? - Stack Overflow

    stackoverflow.com/questions/4508590

    It may help to distinguish between tables and views depending on what your naming convention is. The disadvantage is that you may be limited as far as the name of a table is concerned. Oracle has a limit of 30 characters for this. If you use "Tbl_" as the prefix, you automatically lose 4 characters.

  3. Prefixing database table names - Stack Overflow

    1. In SQL Server 2005 and above the schema feature eliminates the need for any kind of prefix. A good example of their usage can be found by reading about the Schemas in AdventureWorks. In some older versions of SQL server, having a prefix to create a pseudo namespace might of been useful with DBs with lots of tables.

  4. string - KMP prefix table - Stack Overflow

    stackoverflow.com/questions/13792118

    We do not count whole string as suffix or prefix here, it is called self-suffix and self-prefix (at least in Russian, not sure about English terms). So we have string "ababaca". Let's look at it. KMP computes Prefix Function for every non-empty prefix. Let's define s[i] as the string, p[i] as the Prefix function. prefix and suffix may overlap.

Prefixing application names adds no value. 1. 3rd party components should not be going under the same schema/owner as your app tables to cause naming conflicts in the first place. 2. Limited to single database does not mean limited to a single schema. – Amit Naidu. Jul 29, 2011 at 3:30.

  6. 0. Table prefix is not the only solution , but you are right when saying that column names should be unique in your database! Our standard slightly differs than yours, where we use the table name as a suffix (see infra), but the result is the same: each column holds a unique name.

  7. No, there is not. Second, you want to know with regard to a specific dbms product. Then you need to identify it. But I imagine the most likely answer is that you'll get back something like "a.id, b.id" since that's how you'd need to identify the columns in your SQL expression.

  8. and then find the table name I need (assuming I have no idea about exact table name). This is one-step work. Of course, we can always find out the table name through additional steps, but I'd say that with 'tbl' prefix, this is the ONE step work, and that's why I always prefer a prefix (not necessarily 'tbl') in my own homework project.

  9. mysql> drop database if exists prefixdb; Query OK, 4 rows affected (0.01 sec) mysql> create database prefixdb; Query OK, 1 row affected (0.00 sec) mysql> use prefixdb. Database changed. mysql> create table tab1 (num int) ENGINE=MyISAM; Query OK, 0 rows affected (0.05 sec) mysql> create table tab2 like tab1;

  10. I wouldn't rely on Microsoft for any standard - if you look at their northwind database you'll see they use Plural Tables, Singular Column Names, Schema Prefixes for Tables, Table Prefixes for Primary Key Columns, Hungarian-esque Constraint Prefixes and worst of all SPACES " " for multi-word table names.

  11. The prefix variant just takes longer to write and makes it harder to read sql statements with many fields. Even when you are selecting from several tables, this gives you only the benefit of not having to prefix ambiguous fields with the table name. But. SELECT user.name, image.name FROM user, image is not very different from
