the program in Figure 17-5 is written in COBOL; and the program in Figure 17-6 is written in FORTRAN. Although the programs are extremely simple, they illustrate the most basic features of embedded SQL: The embedded SQL statements appear in the midst of host programming language statements. It usually doesn t matter whether the SQL statement is written in uppercase or lowercase; the most common practice is to follow the style of the host language. Every embedded SQL statement begins with an introducer that flags it as a SQL statement. The IBM SQL products use the introducer EXEC SQL for most host languages, and the ANSI/ISO SQL standard specifies it as well. Some embedded SQL products still support other introducers, for backward compatibility with their earlier versions. If an embedded SQL statement extends over multiple lines, the host language strategy for statement continuation is used. For COBOL, PL/I, and C programs, no special continuation character is required. For FORTRAN programs, the second and subsequent lines of the statement must have a continuation character in column 6.

Application programs often use cursors to allow the user to browse through a table of data row by row. For example, the user may ask to see all of the orders placed by a particular customer. The program declares a cursor for a query of the ORDERS table and displays each order on the screen, possibly in a computer-generated form, waiting for a signal from the user to advance to the next row. Browsing continues in this fashion until the user reaches the end of the query results. The cursor serves as a

pointer to the current row of query results If the query draws its data from a single table and it is not a summary query, as in this example, the cursor implicitly points to a row of a database table, because each row of query results is drawn from a single row of the table While browsing the data, the user may spot data that should be changed For example, the order quantity in one of the orders may be incorrect, or the customer may want to delete one of the orders In this situation, the user wants to update or delete this order The row is not identified by the usual SQL search condition; rather, the program uses the cursor as a pointer to indicate which particular row is to be updated or deleted.

TABLE INTEGER NOT NULL, VARCHAR(15) NOT NULL, INTEGER, INTEGER, VARCHAR(10), DATE NOT NULL, INTEGER, DECIMAL(9,2), DECIMAL(9,2) NOT NULL)

Embedded SQL supports this capability through special versions of the DELETE and UPDATE statements, called the positioned DELETE and positioned UPDATE statements, respectively The positioned DELETE statement, shown in Figure 17-30, deletes a single row from a table The deleted row is the current row of a cursor that references the table To process the statement, the DBMS locates the row of the base table that corresponds to the current row of the cursor and deletes that row from the base table After the row is deleted, the cursor has no current row Instead, the cursor is effectively positioned in the empty space left by the deleted row, waiting to be advanced to the next row by a subsequent FETCH statement The positioned UPDATE statement, shown in Figure 17-31, updates a single row of a table The updated row is the current row of a cursor that references the table.

DISPLAY A MESSAGE FOR THE USER WRITE (6,100) 'Deleting salesreps with low quota.' EXECUTE THE SQL STATEMENT EXEC SQL DELETE FROM REPS C WHERE QUOTA < 150000 EXEC SQL COMMIT DISPLAY ANOTHER MESSAGE WRITE (6,100) 'Finished deleting.' RETURN END

To process the statement, the DBMS locates the row of the base table that corresponds to the current row of the cursor and updates that row as specified in the SET clause After the row is updated, it remains the current row of the cursor Figure 17-32 shows an order-browsing program that uses the positioned UPDATE and DELETE statements:.
