Example text

For the record, I have never used PERL and had to Google an overview before I went; it is a very different creature from SQL. One of my students asked if you could write an SQL statement to generate the prime numbers less than 1000 (or any other limit) that scales well. He was bothered by the lack of loops in SQL, and a Prime Number sieve is a common PERL programming exercise. node_id=276103. There are two useful facts from Number Theory: 1. The prime factors of a given number (n) cannot be greater than ceiling (n).

The syntax is: ::= CREATE ASSERTION [] ::= CHECK () As you would expect, there is a DROP ASSERTION statement, but no ALTER ASSERTION statement. An assertion can do things that a CHECK() clause attached to a table cannot do, because it is outside of the tables involved. A CHECK() constraint is always TRUE if the table is empty. For example, it is very hard to make a rule that the total number of employees in the company must be equal to the total number of employees in all the health plan tables.

Here are two anomalies arising from constraint violation. • A5A Read Skew: Suppose transaction T1 reads x, and then a second transaction 2 updates x and y to new values and 20 Chapter 2 TRANSACTIONS AND CONCURRENCY CONTROL COMMITs. If now T1 reads y, it may see an inconsistent state, and therefore produce an inconsistent state as output. • A5B Write Skew: Suppose T1 reads x and y, which are consistent with constraint C, and then a T2 reads x and y, writes x, and COMMITs. Then T1 writes y. If there were a constraint between x and y, it might be violated.
