TIP: In 10, we will demonstrate another method for looping through a set of records using the While statement. Personally, I seldom use cursors; I prefer to use the method demonstrated in 10.

Define regular and delimited identifiers. Select the appropriate datatype. Declare a variable. Assign a value to the variable using a Select, Set, or Update statement. Display the value of the variable to a user. Use global variables. Use the @@identity variable to read the value of a key field. Read the value of the @@error variable to determine if a statement was successful.

Transact-SQL is not a feature-rich programming language, but its statements, if well harnessed, will arm the developer to code even the most complex algorithms. We have demonstrated how the developer can use comments to document code and make it more understandable. We have learned

The CASCADE rule presents a similar problem, as shown in Figure 11-7. This figure contains exactly the same data as in Figure 11-6, but all three delete rules have been changed to CASCADE. Suppose you try to delete Bob from the BOYS table. The delete rules force the DBMS to delete Rover (who likes Bob) from the PETS table, which forces you to delete Betty (who likes Rover) from the GIRLS table, which forces you to delete Sam (who likes Betty), and so on until all of the rows in all three tables have been deleted! For these small tables this might be practical, but for a production database with thousands of rows, it would quickly become impossible to keep track of the cascaded deletions and retain the integrity of the database. For this reason DB2 enforces a rule that prevents referential cycles of two or more tables where all of the delete rules are CASCADE. At least one relationship in the cycle must have a RESTRICT or SET NULL delete rule to break the cycle of cascaded deletions.

the rules that are of the utmost importance in the formulation of comments. We have seen how to implement conditional executions using an If statement and how to use the While statement to implement a loop. We have learned how to schedule executions using the WaitFor statement and the risks involved in overusing the GoTo statement. Cursors are a powerful feature designed to bridge the gap between the relational aspect of database systems and the navigational aspect of client applications. We have seen that the use of cursors creates some performance and structural problems in stored procedures, and we have concluded that they should be used with caution and only for problems that cannot be resolved with set operations.

1. Which datatypes can store strings and what are the differences among them 2. Is it better to use decimal or real variables to store monetary values 3. When variables are assigned with a Select statement that returns a recordset instead of a single record, which values will be assigned to the variables 4. What values will be assigned to the variable when a Select statement returns an empty recordset 5. Create two stored procedures prStoreOrder, which will insert an order and return an Order number, and prStoreOrderItem, which will insert the item of the order. 6. Create a stored procedure that creates a temporary table with just one integer field. The stored procedure should then insert numbers from 1 to 100 into the table and at the end, return those numbers as a resultset to the caller. 7. Stored procedure sp_spaceused can return information about the space used by a database object. Collect the names of all tables in the Asset database using:
