All this does is select some rows from my large table, and join to a reference table to translate a code into a description to eliminate data based on that description. This is typical of the way in which an end-user query would have to make use of the type table. (The SQL in the test case in the download does not use the literal values 'CURRENCY' and 'GBP', but I thought that a couple of meaningful code samples would help make the point of the example more clearly.) So what does the execution plan look like It depends on what you ve done with your reference tables. Here s one option for the reference table the currency data (or 'CLASS1' as it really was) is stored in a table all by itself: create table type1 as select rownum-1 'CLASS1' lpad(rownum-1,10,'0') from all_objects where rownum <= 20 ;

Based on this definition, an informal argument about the query would be that we are aiming for 1,000 rows from the base table, and the restriction to one description out of 20 (rownum <= 20) in the reference table will give us 50 rows in the final result set. Here s the execution plan: Execution Plan (9.2.0.6 autorace) ---------------------------------------------------------0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=287 Card=50 Bytes=1950) 1 0 HASH JOIN (Cost=287 Card=50 Bytes=1950) 2 1 TABLE ACCESS (FULL) OF 'TYPE1' (Cost=2 Card=1 Bytes=20) 3 1 TABLE ACCESS (FULL) OF 'T1' (Cost=284 Card=1001 Bytes=19019) Sure enough, the calculated cardinality for the join is 50 rows. We can check the formulae presented in their simplest form given we have no null values to worry about: Join Selectivity = 1 / greater(20, 20) = 1/20 Join Cardinality = 1/20 * (20/20 * (500,000 * 1001/500000)) = 50

CellPadding: 0 CellSpacing: 0 Rows: Add a new row, with its BackColor set to #D3E5FA.

The ImageButton control will redirect the user back to the upload page. Set its properties as follows: ID: btnBackImg AlternateText: Back to Upload ImageUrl: Images/back.gif ImageAlign: Middle 10. The bottom LinkButton control links to the upload page. Set its ID to btnBackLink and its Text to Back to Upload. The error panel and its controls will be already properly configured, as you use the same approach to handling errors as in the UploadList.aspx form. How It Works This form will show the statistics that you ll add in the code-behind page. The table at the top of the page will be populated with the results of some predefined queries, while the second table will execute a custom XPath query built from the value in the text boxes above it. It will allow the user to select the <Attendee> elements whose child elements <YearIn> and <YearOut> text values match the desired range. Before moving on to perform the queries, however, we need to introduce one last XMLrelated standard: the Document Object Model.

XmlReader-based objects provide forward-only access to the underlying XML data, which means that as soon as you move forward, you lose all information pertaining to the previous element. Clearly, such an approach is unsuited to querying a document, because you would end up reading the entire file for every query you perform. Even if the element you were looking for was the first one in the document, there would be no way to know that for sure, and you would need to read it in its entirety to be certain. To perform queries effectively, you really need the complete document in memory, so that you can perform all the queries without needing to reparse the file. The W3C again has an answer: the Document Object Model (or DOM). The DOM defines the way an XML document is stored in memory, and how its nodes are loaded, accessed, and changed using a collection approach: each node contains other nodes
