Retrieving Data
FIGURE 5-2
A sample syntax diagram
Variable items in a SQL statement (such as the table name and search condition in Figure 5-2) are shown in lowercase italics. It s up to you to specify the appropriate item value(s) each time the statement is used. Optional clauses and keywords, such as the WHERE clause in Figure 5-2, are indicated by alternate paths through the syntax diagram. When a choice of optional keywords is offered, the default choice (that is, the behavior of the statement if no keyword is specified) is UNDERLINED.
Names
The objects in a SQL-based database are identified by assigning them unique names. Names are used in SQL statements to identify the database object on which the statement should act. The most fundamental named objects in a relational database are table names (which identify tables), column names (which identify columns), and user names (which identify users of the database); the original SQL1 standard specified conventions for naming these objects. Subsequent versions of the SQL standard significantly expanded the list of named entities to include schemas (collections of tables), constraints (restrictions on the contents of tables and their relationships), domains (sets of legal values that may be assigned to a column), and several other types of objects. Many SQL implementations support additional named objects such as stored procedures, primary key/foreign key relationships, data entry forms, and data replication schemes. The original ANSI/ISO standard specified that SQL names must contain 1 to 18 characters, must begin with a letter, and may not contain any spaces or special punctuation characters. The SQL2 standard increased the maximum to 127 characters (the standard actually specifies less than 128 ), and this remains unchanged through SQL:2006. In practice, the names supported by SQL-based DBMS products vary significantly. It s common to see tighter restrictions on names that are connected to other software outside of the database (such as user names, which may correspond to login names used by an operating system), and looser restrictions on names that are private (internal) to the database. The various products also differ in the special characters they permit in table names. For portability, it s best to keep names relatively short and to avoid the use of special characters, except of course the underscore character (_), which is used to separate words in SQL names.
Table Names
When you specify a table name in a SQL statement, SQL assumes that you are referring to one of your own tables (that is, a table that you created). Usually, you will want to choose table names that are short but descriptive.

SQL Basics
The table names in the sample database (ORDERS, CUSTOMERS, OFFICES, SALESREPS) are good examples. In a personal or departmental database, the choice of table names is usually up to the database developer or designer. A larger, shared-use corporate database, may have corporate standards for naming tables, to ensure that table names are consistent and do not conflict. In addition, most DBMS brands allow different users to create tables with the same name (that is, both Joe and Sam can create a table named BIRTHDAYS). The DBMS uses the appropriate table, depending on which user is requesting data. With the proper permission, you can also refer to tables owned by other users, by using a qualified table name. A qualified table name specifies both the name of the table s owner and the name of the table, separated by a period (.). For example, Joe could access the BIRTHDAYS table owned by Sam by using the qualified table name:
