Each time your program requires a new row from the result set, simply issue a FETCH command against the cursor. This is very much like reading the next record from a le in an older at le system. Remember that the cursor is merely a pointer into the result set. Every time a fetch is issued, the cursor is advanced one row, and the row currently pointed to is returned to the calling program (that is, the program that issued the FETCH). If there are no more rows in the result set (that is, if the cursor has been advanced past the last row in the result set), a code is returned to the calling program to indicate this. Another detail handled by the fetch is mapping the columns returned to programming language variables (called host language variables, or just host variables). This is done with the INTO clause, and naturally the syntax of the variable names will vary from one programming language to another. The general form of the FETCH statement is java upc-a Generate UPC-A barcode in Java class using Java UPC-A ...

The simplest SQL statements to embed in a program are those that are self-contained and do not produce any query results. For example, consider this interactive SQL statement: Delete all salespeople with sales under $150,000. java upc-a Java UPC-A Generator | Barcode UPCA Generation in Java Class ...

Integrate UPC-A barcode generation function to Java applications for drawing UPC-A in Java . Figures 17-4, 17-5, and 17-6 show three programs that perform the same task as this interactive SQL statement, using embedded SQL. The program in Figure 17-4 is written in C, 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: I 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. I 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 SQL2 standard specifies it as well. Some embedded SQL products still support other introducers, for backward compatibility with their earlier versions. 17: FETCH cursor_name [INTO variable_list]; java upc-a racca3141/UPC: Build a UPC-A label. - GitHub

I 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. I Every embedded SQL statement ends with a terminator that signals the end of the SQL statement. The terminator varies with the style of the host language. In COBOL, the terminator is the string END-EXEC., which ends in a period like other COBOL statements. For PL/I and C, the terminator is a semicolon (;), which is also the statement termination character in those languages. In FORTRAN, the embedded SQL statement ends when no more continuation lines are indicated. main() { exec sql include sqlca; exec sql declare salesreps (empl_num name age rep_office title hire_date manager quota sales than the internal room temperature, as a result, the room would warm up. In reality it appeared that most of the heat was simply dumped to the cold outside. A series of improvements were made to the design of the Trombe wall which significantly increased its performance. In the improved version of the Trombe wall, there are vents at the top and bottom of the wall, and also on the glazing. table integer not null, varchar(15) not null, integer integer, varchar(10), date not null, integer, money, money not null); /* Display a message for the user */ printf("Deleting salesreps with low quota.\n"); /*Execute the SQL statement */ exec sql delete from salesreps where sales < 150000.00; PROGRAMMING WITH SQL /* Display another message */ printf("Finished deleting.\n"); exit(); } Notice that the FETCH statement refers only to the cursor name and the host variables. The cursor declaration ties the cursor to the table(s) and column(s) being referenced. In most SQL implementations, host variables must be declared before they can be referenced in a FETCH statement. The syntax and rules for declaring host variables vary across SQL implementations, so you should consult your vendor s documentation for details. Here is an example that will run in most SQL implementations (the INTO clause has been intentionally left out). However, Oracle requires the INTO clause along with some other statements that start and end a PL/SQL statement block, so this example won t work in Oracle without some modi cations: Figure 17-4. java upc-a BE THE CODER > Barcodes > Barcode4j Examples > Barcode UPC-A
