The last format of FROM parameters handles joins As discussed in 6, joins allow you to easily match relational data between tables in the database The NATURAL keyword is used to join tables on common column names Alternatively, you can use the ON keyword to define a join condition, or the USING keyword to define specific matching column names in both tables

Encoding Bar Code In .NET
Using Barcode encoder for .NET framework Control to generate, create bar code image in .NET framework applications.
This example shows the use of two inner joins to obtain data from tables related to the Order table via defined foreign keys The Customer and Order tables are joined on the CustomerID column, while the Order and Product tables are joined on the ProductID column The Customer table matches the LastName and FirstName values related to the CustomerID value stored in the Order table The Product table matches the ProductName value related to the ProductID stored in the Order table

The elements of the WHERE clause were discussed in detail in 6 The WHERE clause specifies one or more conditions that filter data from the result set While the concept is simple, in reality the WHERE clause conditions can get somewhat complex, specifying multiple conditions joined using Boolean operators, such as AND, OR, or NOT

GROUP BY expression [,]
The GROUP BY clause specifies one or more columns of data to group together in the result set Unlike the DISTINCT clause, the GROUP BY clause allows you to aggregate values of the grouped records This is almost always used with a PostgreSQL function that aggregates values from similar records This example shows how to produce a report showing the total number of products currently ordered by customers:
7:
Using Advanced SQL
test=> select sum("Order""Quantity"), "Order""ProductID" from test-> store"Order" group by "ProductID"; sum | ProductID + 12 | LAP001 1 | DES001 (2 rows) test=>
The GROUP BY clause must declare which column is used to sort the records The sum() function adds the values of the Quantity column of each record (This will be discussed further in 8) Be careful with the GROUP BY and ORDER BY clauses It is important to remember that the GROUP BY clause groups similar records before the rest of the SELECT command is evaluated, while the ORDER BY clause orders records after the SELECT commands are processed The sum() function would not work properly using the ORDER BY clause, since the records would not be ordered until after the sum() function executes
The HAVING Clause
HAVING condition [,]
The HAVING clause is similar to the WHERE clause, in that it is used to define a filter condition to limit records used in the GROUP BY clause Records that do not satisfy the WHERE conditions are not processed by the GROUP BY clause The HAVING clause filters the records contained in the result set after the GROUP BY clause groups the records
The Set Operation Clauses
select1 [ (UNION | INTERSECT | EXCEPT ]) [ ALL ] select2
The Set Operation clauses use mathematical set theory to determine the result set of two separate SELECT commands The Set Operation clause types are: UNION Display all result set records in both select1 and select2 INTERSECT Display only result set records that are in both select1 and select2 EXCEPT Display only result set records that are in select1 but not in select2 By default, duplicate records in the output set are not displayed The ALL keyword is used to display all records from the output, including duplicate records The set operation is performed on the result sets of the SELECT commands The result sets must have the same number of columns, and the columns must have the same data types
