In this case, the WHERE clause selects two rows of the ORDERS table, and SQL removes both of them from the table. Conceptually, SQL applies the WHERE clause to each row of the ORDERS table, deleting those where the search condition yields a TRUE result and retaining those where the search condition yields a FALSE or NULL result. Because this type of DELETE statement searches through a table for the rows to be deleted, it is sometimes called a searched DELETE statement. This term is used to contrast it with

Like all declarations, the DECLARE CURSOR statement must physically appear in the program before any statements that reference the cursor that it declares Most SQL implementations treat the cursor name as a global name that can be referenced inside any procedures, functions, or subroutines that appear after the DECLARE CURSOR statement It s worth noting that not all SQL implementations treat the DECLARE CURSOR statement strictly as a declarative statement, and this can lead to subtle problems Some SQL precompilers actually generate code for the DECLARE CURSOR statement (either host language declarations or calls to the DBMS, or both), giving it some of the qualities of an executable statement.

For these precompilers, the DECLARE CURSOR statement must not only physically precede the OPEN, FETCH, and CLOSE statements that reference its cursor, but it must sometimes precede these statements in the flow of execution or be placed in the same block as the other statements In general, you can avoid problems with the DECLARE CURSOR statement by following these guidelines: I Place the DECLARE CURSOR statement right before the OPEN statement for the cursor This placement ensures the correct physical statement sequence, it puts the DECLARE CURSOR and the OPEN statements in the same block, and it ensures that the flow of control passes through the DECLARE CURSOR statement, if necessary It also helps to document just what query is being requested by the OPEN statement.

another form of the DELETE statement, called the positioned DELETE statement, which always deletes a single row. The positioned DELETE statement applies only to programmatic SQL and is described in 17. Here are some additional examples of searched DELETE statements: Delete all orders placed before November 15, 2007.

I Make sure that the FETCH and CLOSE statements for the cursor follow the OPEN statement physically as well as in the flow of control..

Delete all rows for customers served by Bill Adams, Mary Jones, or Dan Roberts (employee numbers 105, 109, and 101).

The OPEN statement, shown in Figure 17-25, conceptually opens the table of query results for access by the application program. In practice, the OPEN statement actually causes the DBMS to process the query, or at least to begin processing it. The OPEN statement thus causes the DBMS to perform the same work as an interactive SELECT statement, stopping just short of the point where it produces the first row of query results.

The WHERE clause in a DELETE statement is optional, but it is almost always present. If the WHERE clause is omitted from a DELETE statement, all rows of the target table are deleted, as in this example: Delete all orders.

Figure 17-25.

Although this DELETE statement produces an empty table, it does not erase the ORDERS table from the database. The definition of the ORDERS table and its columns is still stored in the database. The table still exists, and new rows can still be inserted into the ORDERS table with the INSERT statement. To erase the definition of the table from the database, the DROP TABLE statement (described in 13) must be used. Because of the potential damage from such a DELETE statement, be careful to always specify a search condition, and be sure that it actually selects the rows you want. When using interactive SQL, it s a good idea first to use the WHERE clause in a SELECT statement to display the selected rows. Make sure they are the ones you want to delete, and only then use the WHERE clause in a DELETE statement.
