Online statistics are often required on the website. In the past, the common practice is to combine login and exit functions, that is, when the user entered the user name password to log in when the Counter plus 1, and then when the user clicks the Exit button to exit the system when the counter minus 1. There are some drawbacks to this approach, for example: After the user log in normally, may forget to click the Exit button, but closes the browser directly, causes the counter to reduce 1 the o

To parse a single Value in the SQL Server XML data type column, you can use XQuery in the Value () method inherent in the XML data type. Name the parsed data packet DIM_CUSTOMER.dtsx.It is optional to develop SSIS data packets for the date dimension. Since this dimension typically does not have source data, the easiest way to load it is t
