Informally, we shouldn t be surprised that the cost of visiting the table was 20. We were expecting about 20 rows and knew that those rows were scattered all around the table. So we can accept that the incremental cost of 20 in the table line relates to the 20 different blocks that we will have to visit to acquire those 20 different rows. Similarly, when we see the cost of using the index was 5, we might allocate two units to walking down the branch levels (the blevel of the index was 2). But that leaves three more units to account for perhaps the optimizer has estimated that we will walk three leaf blocks to get the 20 rowids we need. An informal argument is fine as a starting point, but if we want to investigate the formula and understand the optimizer s use of indexes a little better, we now need to know the significance of the two selectivities and the clustering_factor. vb.net code 39 reader VB .

Source report templates, created either by using the API or by parsing JRXML files, are subject to the report compilation process before they are filled with data. This is necessary to make various consistency validations and to incorporate into these report templates data used to evaluate all report expressions at runtime. The compilation process transforms net.sf.jasperreports.engine.design.JasperDesign objects into net.sf.jasperreports.engine.JasperReport objects. Both classes are implementations of the same basic net.sf.jasperreports.engine.JRReport interface. However, JasperReport objects cannot be modified once they are produced, while JasperDesign objects can. This is because some modifications made on the report template would probably require revalidation, or if a report expression is modified, the compiler-associated data stored inside the report template would have to be updated. JasperDesign objects are produced when parsing JRXML files using the net.sf. jasperreports.engine.xml.JRXmlLoader or created directly by the parent application if dynamic report templates are required. The GUI tools for editing JasperReports templates also work with this class to make in-memory modifications to the report templates before storing them on disk. A JasperDesign object must be subject to the report compilation process to produce a JasperReport object. birt barcode free, word aflame upci, birt code 39, birt pdf 417, code 128 word barcode add in, birt upc-a vb.net code 39 reader read code 39 barcode with vb . net - Stack Overflow

One item to notice in the web site s Properties dialog box is the Logging facility. IIS will keep a log of all requests to the web server, unless you configure it not to. Click the Properties button in the Logging section to open a dialog box that allows you to customize the type of information logged and the frequency of generation of log files, as shown in Figure B-2. The IIS logs are stored in the specified folder, with the file name shown in the label below the field. The content of such a log file might look something like this: #Software: Microsoft Internet Information Services 5.0 #Version: 1.0 #Date: 2004-07-31 12:31:54 #Fields: time c-ip cs-method cs-uri-stem sc-status 12:31:54 127.0.0.1 GET /FriendsReunion/default.aspx 200 12:32:05 127.0.0.1 POST / FriendsReunion /default.aspx 200 12:33:01 192.168.202.185 GET / FriendsReunion /default.aspx 200 12:33:08 192.168.202.185 POST / FriendsReunion /default.aspx 200 12:34:50 192.168.0.121 GET / FriendsReunion /default.aspx 200 12:35:00 192.168.0.121 POST / FriendsReunion /default.aspx 200 vb.net code 39 reader C# .

In 3, I described the selectivity as the fraction of the rows that the optimizer expected to find based on the predicates supplied. But now I have raised the stakes to two selectivities, the effective index selectivity and the effective table selectivity. The principle is exactly the same, though. Forget about the table for a moment; what fraction of the row entries in the index will we return if we use the three predicates from the query All three predicates are on columns in the index, so we investigate all three of them, starting with their density or num_distinct: Figure B-2. IIS Logging settings This sample log shows a request for the main page of the Friends Reunion application, Default.aspx, originating from the local machine (the request was made by the 127.0.0.1 loopback IP address). It also shows a couple of other requests for the same page from other machines on the local network. The IP addresses of all requesting machines are listed, along with the name of the resource requested from the client, either by using the HTTP GET verb or the HTTP POST verb. The number 200 at the end of each entry is an HTTP response code, which indicates that the operation was successful. Logging hits to the web server is a great way to watch for malicious activity and to track general usage of your site, so usually you should leave it turned on. n1 = {constant} ind_pad = {constant} n2 = {constant} (Target: 1 row in 25, or 4% of the rows, or 0.04 * number of rows) (Target: 100% of the rows) (Target: 1 row in 20, or 5% of the rows, or 0.05 * number of rows) vb.net code 39 reader Visual Studio .
