You won't have to remember whether you named a particular table with an underscore, title case, etc.Sorry, you can't reply to this topic. Whichever you choose, you should try to maintain the same convention throughout your database.Įstablishing a naming convention will help enormously when you start to write queries against your database. If you choose customers, then you should also call a table that holds all products products and not product. Do you call a table that holds all customer records customer or customers. So a table could be called tblCustomers or tbl_customers etc. For example, prefixing tables with tbl or tbl_ and stored procedures with sp or sp_. Some people also like to prefix their database objects. You could call the database FruitShop (title case), FRUITSHOP (uppercase), fruitshop (lowercase), fruit_shop (with an underscore separator), etc. It's a good idea to keep a consistent naming convention. You could even combine both scripts into one if you wish. You could also write another script that populates the tables with the initial data required. You could write a long script that creates a database and many tables as well as other database objects. This is a simple example that creates a database and a table within that database. We'll look at creating tables next, but for now, here's a quick example:ĬREATE TABLE Fruit (FruitName VARCHAR(20), DateEntered DATETIME) It is simply a matter of combining SQL statements, one after the other, for each object you want to create. You would normally write a script that creates the database and all its tables and other objects all in one go.įortunately, doing this is quite straightforward. In reality, when you create a database, you don't just create an empty database and then think about what tables will go into it later. You need to think about what tables and other objects it will contain, as well as the data that will be stored in the database. Database Designīefore you create your database you need to think about its design. If you find that a command that you write doesn't run, check that you've included the semicolon after each statement. There are some exceptions but most commands follow this convention. MySQL commands usually consist of an SQL statement followed by a semicolon. The above example uses semicolons ( ) to mark the end of each statement. CREATE DATABASE FruitShop About Semicolons
