Append to the statement the keyword DES to specify descending orderings. SELECT * FROM table LIMIT first, count returns count rows starting from first.

Calculating EAN-8 / EAN - 13 check digits with VB . NET . The following two code snippets show how to calculate an EAN8 / EAN13 check digit with Visual Basic . php' ); } > Dealing with a returning user s submitted password is a bit simpler, because you don t need to check whether it meets our specified criteria (you did that when it was first submitted as the password for a new user, as shown in the preceding fragment) You once again store the submitted password in a variable, and query the database for a record, using the sanitized version of the submitted username This allows us to retrieve both the salt that was used to hash the original password, and the stored value of that hash You then (as with the new user) construct a hash of the submitted password by concatenating it with the retrieved salt and using the sha1() function on the result Finally, you simply compare the hashed result to the hash that you have previously stored. However, this will not work, because if there is no error message, the UI Messages component will not generate any HTML code at all. It means subsequent Ajax operations will be unable to find the HTML element to update. To solve this problem, put that UI Messages component into a panel and update the panel instead (see Listing 7 11). Sometimes you need to obtain some global information on your data and are not interested in the details. This is where the second format of SELECT comes to the rescue. Listing E-10 shows how you use SELECT to apply a function. Listing E-10. SELECT to Apply a Function SELECT [ALL | DISTINCT ] [<select_list>] {COUNT (*) | <function>} [FROM <table_references> [GROUP BY col_name [ASC | DESC], ... [WITH ROLLUP] [HAVING <where_condition>] ] ] ; <select_list> = col_name [, <select_list>] <table_references> = one or more table and/or view names separated by commas <function> = {AVG | MAX | MIN | SUM | COUNT} ([{ALL | DISTINCT}] <val>) Here are some examples of how you apply a function with SELECT: SELECT COUNT (*) FROM employee_tbl counts the number of rows in the employee table. SELECT department, citizenship, gender COUNT(employee_id) FROM employee_tbl GROUP BY department, citizenship, gender provides counts of employees for each possible department, citizenship, and gender combination. If you append WITH ROLLUP to the statement, you ll also obtain partial totals, as shown in Table E-5. SELECT last_name COUNT(first_name) FROM employee_tbl GROUP BY first_name HAVING COUNT(first_name) > 1 counts the number of first names for each family name but only reports the family names that appear with more than one first name. HAVING has the same function for the aggregated values produced by GROUP BY that WHERE had for data selection. vb.net ean 13 Visual Basic . Net Programming How to Create EAN - 13 Barcode ...
