Similarly, a role-name can be used in the FROM clause of a REVOKE statement as shown in Figure 15-7. Here are some examples: Create role OPUSER to organize the privileges required by users in the Order Processing department.

Any references to the target table in the subqueries are thus outer references to the row of the target table currently being tested by the UPDATE statement's WHERE clause The SQL2 standard again removed this restriction and specifies that a reference to the target table in a subquery is evaluated as if none of the target table had been updated..

CREATE ROLE OPUSER;

GRANT SELECT, INSERT, DELETE, UPDATE ON ORDERS TO OPUSER; GRANT SELECT ON CUSTOMERS TO OPUSER; GRANT UPDATE (COMPANY, CUST_REP) ON CUSTOMERS TO OPUSER; GRANT SELECT ON SALESREPS TO OPUSER;

QL is a dual-mode language. It is both an interactive database language used for ad hoc queries and updates and a programmatic database language used by application programs for database access. For the most part, the SQL language is identical in both modes. The dual-mode nature of SQL has several advantages:

Grant the role to Julio, Sumit, and Yolanda, the three current clerks in the Order Processing department.

I It is relatively easy for programmers to learn how to write programs that access the database. I Capabilities available through the interactive query language are also automatically available to application programs. I The SQL statements to be used in a program can be tried out first using interactive SQL and then coded into the program. I Programs can work with tables of data and query results instead of navigating their way through the database. This chapter summarizes the types of programmatic SQL offered by the leading SQL-based products and then describes the programmatic SQL used by the IBM SQL products, which is called embedded SQL.

Summary

SQL is a language and can be used programmatically, but it would be incorrect to call SQL a programming language. SQL lacks even the most primitive features of real programming languages. It has no provision for declaring variables, no GOTO statement, no IF statement for testing conditions, no FOR, DO, or WHILE statements to construct loops, no block structure, and so on. SQL is a database sublanguage that handles specialpurpose database management tasks. To write a program that accesses a database, you must start with a conventional programming language, such as COBOL, PL/I, FORTRAN, Pascal, or C and then add SQL to the program. The initial ANSI/ISO SQL standard was concerned exclusively with this programmatic use of SQL. In fact, the standard did not even include the interactive SELECT statement described in s 6 through 9. It only specified the programmatic SELECT statement described later in the section Data Retrieval in Embedded SQL. The SQL2 standard, published in 1992, expanded its focus to include interactive SQL (called direct invocation of SQL in the standard) and more advanced forms of programmatic SQL (the dynamic SQL capabilities described in 20). Commercial SQL database vendors offer two basic techniques for using SQL within an application program: I Embedded SQL. In this approach, SQL statements are embedded directly into the program s source code, intermixed with the other programming language statements. Special embedded SQL statements are used to retrieve data into the program. A special SQL precompiler accepts the combined source code and, along with other programming tools, converts it into an executable program.

Grant UPDATE on the SALESREPS table to role OPUSER. Note that all three users currently granted the role immediately acquire the new privilege.

GRANT UPDATE ON SALESREPS TO OPUSER;

with a primary key that was NULL (or partially NULL, if the primary key is composed of more than one column). Because of the NULL value, the DBMS cannot conclusively decide whether the primary key duplicates one that is already in the table. The answer must be maybe, depending on the real value of the missing (NULL) data. For this reason, the SQL standard requires that every column that is part of a primary key must be declared NOT NULL. The same restriction applies for every column that is named in a uniqueness constraint. Together, these restrictions ensure that columns that are supposed to contain unique data values in each row of a table actually do contain unique values.

A new employee, Francois, has joined the Order Processing department. Grant the OPUSER role to him. Note that he immediately acquires all the privileges in the role.
