For each parent/child relationship created by a foreign key in a database, the SQL2 standard allows you to specify an associated delete rule and an associated update rule. The delete rule tells the DBMS what to do when a user tries to delete a row of the parent table. These four delete rules can be specified: The RESTRICT delete rule prevents you from deleting a row from the parent table if the row has any children. A DELETE statement that attempts to delete such a parent row is rejected with an error message. Deletions from the parent table are thus restricted to rows without any children. Applied to Figure 11-1, this rule can be summarized as "You can't delete an office if any salespeople are assigned to it." The CASCADE delete rule tells the DBMS that when a parent row is deleted, all of its child rows should also automatically be deleted from the child table. For Figure 11-1, this rule can be summarized as "Deleting an office automatically deletes all the salespeople assigned to that office." The SET NULL delete rule tells the DBMS that when a parent row is deleted, the foreign key values in all of its child rows should automatically be set to NULL. Deletions from the parent table thus cause a "set to NULL" update on selected columns of the child table. For the tables in Figure 11-1, this rule can be summarized as "If an office is deleted, indicate that the current office assignment of its salespeople is unknown." how to use code 39 barcode font in crystal reports Create Code 39 Barcodes in Crystal Reports - BarCodeWiz

The way your program handles its cursors can have a major impact on database performance Recall from 12 that the SQL transaction model guarantees the consistency of data during a transaction In cursor terms, this means that your program can declare a cursor, open it, fetch the query results, close it, reopen it, and fetch the query results again and be guaranteed that the query results will be identical both times The program can also fetch the same row through two different cursors and be guaranteed that the results will be identical In fact, the data is guaranteed to remain consistent until your program issues a COMMIT or ROLLBACK to end the transaction Because the consistency is not guaranteed across transactions, both the COMMIT and ROLLBACK statements automatically close all open cursors.

Behind the scenes, the DBMS provides this consistency guarantee by locking all of the rows of query results, preventing other users from modifying them If the query produces many rows of data, a major portion of a table may be locked by the cursor Furthermore, if your program waits for user input after fetching each row (for example, to let the user verify data displayed on the screen), parts of the database may be locked for a very long time In an extreme case, the user might leave for lunch in mid-transaction, locking out other users for an hour or more! To minimize the amount of locking required, you should follow these guidelines when writing interactive query programs: I Keep transactions as short as possible I Issue a COMMIT statement immediately after every query and as soon as possible after your program has completed an update. how to use code 39 barcode font in crystal reports Code 39 barcode Crystal Reports custom functions from Azalea ...

A positive SQLCODE value indicates a warning condition. For example, truncation or rounding of a data item retrieved by the program would produce a warning. A separate positive value is assigned to each runtime warning that can occur. The most common warning, with a value of +100 in most implementations and in the SQL standard, is the out-of-data warning returned when a program tries to retrieve the next row of query results and no more rows are left to retrieve. Because every executable embedded SQL statement can potentially generate an error, a well-written program will check the SQLCODE value after every executable embedded SQL statement. Figure 17-10 shows a C program excerpt that checks the SQLCODE value. Figure 17-11 shows a similar excerpt from a COBOL program. I Avoid programs that require a great deal of user interaction or that browse through many rows of data I If you know that the program will not try to refetch a row of data after the cursor has moved past it, use one of the less restrictive isolation modes described in 12 This allows the DBMS to unlock a row as soon as the next FETCH statement is issued I Avoid the use of scroll cursors unless you have taken other actions to eliminate or minimize the extra database locking they will cause I Explicitly specify a READ ONLY cursor, if possible.. By the time the SQL2 standard was being written, virtually all commercial SQL products were using the SQLCODE variable to report error conditions in an embedded SQL program. However, the different products used different error numbers to report the same or similar 17: 17: - 219 - Summary . . . exec sql delete from salesreps where quota < 150000; if (sqlca.sqlcode < 0) goto error_routine; . . . error_routine: printf("SQL error: %ld\n, sqlca.sqlcode); exit(); . . . code 39 font crystal reports Code 39 barcode Crystal Reports custom functions from Azalea ...
