This prohibition exists for the same reason that the NULL keyword is not allowed in the search condition it makes no sense to test whether QUOTA and NULL are equal, because the answer will always be NULL (unknown). Instead of using the indicator variable, you must use an explicit IS NULL test. This pair of embedded SQL statements accomplishes the intended task of the preceding illegal statement:

if (amount_ind < 0) { exec sql delete from salesreps where quota is null; } else { exec sql delete from salesreps where quota = :amount; }

Before you explore second normal form, you must understand the concept of functional dependence For this de nition, I ll use two arbitrary attributes, cleverly named A and B Attribute B is functionally dependent on attribute A if at any moment in time there is no more than one value of attribute B associated with a given value of attribute A Lest you wonder what planet the author lived on before this one, let s try to make the de nition more understandable First, saying that attribute B is functionally dependent on attribute A also means that attribute A determines attribute B, or that A is a determinant (unique identi er) of attribute B Second, let s have another look at relations in Figure 1-5.

Java Barcode Reader Tutorial to scan, read linear, 2d barcodes in ...
Java Barcode Reader is a Java barcode scanning library which scan and read 1D (linear) and 2D (matrix) barcodes from image files. Besides Java Barcode Reader library, OnBarcode also provides Java Barcode Generator for generating linear and 2D barcodes in the Java program.

Using the embedded SQL features described thus far, you can embed any interactive SQL statement except the SELECT statement in an application program. Retrieving data with an embedded SQL program requires some special extensions to the SELECT statement. The reason for these extensions is that there is a fundamental mismatch between the SQL language and programming languages such as C and COBOL: a SQL query produces an entire table of query results, but most programming languages can manipulate only individual data items or individual records (rows) of data. Embedded SQL must build a bridge between the table-level logic of the SQL SELECT statement and the row-by-row processing of C, COBOL, and other host programming languages. For this reason, embedded SQL divides SQL queries into two groups: I Single-row queries. You expect the query results to contain a single row of data. Looking up a customer s credit limit or retrieving the sales and quota for a particular salesperson are examples of this type of query. I Multirow queries. You expect that the query results may contain zero, one, or many rows of data. Listing the orders with amounts over $20,000 or retrieving the names of all salespeople who are over quota are examples of this type of query. Interactive SQL does not distinguish between these two types of queries; the same interactive SELECT statement handles them both. In embedded SQL, however, the two types of queries are handled very differently. Single-row queries are simpler to handle and are discussed in the next section. Multirow queries are discussed shortly.

Many useful SQL queries return a single row of query results. Single-row queries are especially common in transaction-processing programs, where a user enters a customer number or an order number and the program retrieves relevant data about the customer or order. In embedded SQL, single-row queries are handled by the singleton SELECT statement, shown in Figure 17-19. The singleton SELECT statement has a syntax much like that of the interactive SELECT statement. It has a SELECT clause, a FROM clause, and an optional WHERE clause. Because the singleton SELECT statement returns a single row of data, there is no need for a GROUP BY, HAVING, or ORDER BY clause. The INTO clause specifies the host variables that are to receive the data retrieved by the statement. Figure 17-20 shows a simple program with a singleton SELECT statement. The program prompts the user for an employee number and then retrieves the name, quota, and sales of the corresponding salesperson. The DBMS places the three retrieved data items into the host variables repname, repquota, and repsales, respectively.
