microstrategy data sources

When you do a project, you need to display the first few data from different groups in the same GridViewSeveral technical points:1, data grouping, this method does not use GROUP by2. Several query merge bindings with the same result format3, take the query results before or after a number of datapublic int Bindliftdata (){int count = 0;using (mysqlconnection conn = new Mysqlconnection (dbserver)){Frddata db

compensation mechanismFor those with high performance requirements, but not high consistency requirements of the system, often not demanding system real-time consistency, as long as the final consistency within an allowable time period, which makes the transaction compensation mechanism a feasible solution. The transaction compensation mechanism is initially proposed in the process of "long transaction", but it is very useful for the distributed system to ensure the consistency. In general, unl

Data Import from oracle to mysql (applicable to the mutual import between any data sources), oraclemysql To release some resources in the production database, you need to migrate the API module to mysql and export data. When I tried the oracle to mysql tool, the Migration reports an error. Such a large amount of

Using Java to dynamically create ODBC data sources to access DBF files requires the use of registry to modify the registry. In fact, the main is the dynamic creation of ODBC data sources, the beginning is very simple, you can set up a data source manually, of course, can be

contents and settings of all XML document data sources are placed in the params parameter. It defines 3 parameters that need to be passed to the report template: 1. In jasperreports, parameters are organized through a map collection, and in the example program (3), a variable named title is passed to the report template with the value "data source from XML

Damn bad controls. Bind it to a data source, such as list When you add or delete data from such data sources, The ListBox control will not synchronize with the data source. The grid control is automatically synchronized. At this time, if you call ListBox. Items. Add

Talking about multi-data sources, generally to solve those problems, master-slave mode or business complex need to connect different sub-Libraries to support the business. Our project is the latter model, the Internet to find a lot, mostly based on JPA to do a long data source solution, or is the old spring Multi-data

Project needs to get data from other sites, because it is a temporary addition to the requirements, at the beginning of the project did not expect to need multiple data sources So Baidu a bit, found that only need to change the spring applicationcontext.xml files and write three tool classes can be a perfect implementation Applicationcontext.xml Dataso

TESTMETHOD1 nodes, one for each of the TESTMETHOD2,TESTMETHOD3,TESTMETHOD4 nodes, and in the Testdataprovider.java file, define the TESTMETHOD1,TESTMETHOD2,TESTMETHOD3,TESTMETHOD4 four test functions, and TESTMETHOD4 does not use Dataprovider, So the running result should be testmethod1 run two times, testmethod2,testmethod3,testmethod4 each run again, the results are as follows:Method1 received:1method1 received:3method2 received:3method3 received:3method4 received:4 Passed:testmethod1 ({input

Sometimes you need to connect to multiple databases, data sources are inconsistent and need to be configured.1, configuration XML.

This article illustrates how PHP connects to ODBC data sources and saves and queries data. Share to everyone for your reference. The specific implementation code is as follows: Copy Code code as follows: $CONNSTR = "Driver=microsoft Access Driver (*.mdb);d bq=". Realpath ("Db.mdb"); $connid = Odbc_connect ($connstr, "", "", SQL_CUR_USE_ODBC); $odb

spring2.0 later added abstractroutingdatasource this thing provides a dynamic switching data source. Abstractroutingdatasource inherits the Abstractdatasource,abstractdatasource is a subclass of Javax.sql.DataSource. Here is an example of a dynamically switching data source: 1. configuration file configuration in Spring.xml 2. Creating an implementation class for dynamically switching

service, injecting the Servie into the controller, interacting with the server In actual projects, the service also needs to interact with the server. var app = Angular.module ("App", []); App.service ("Todoservice", Function ($q, $timeout) { This.gettodos = function () { var d = $q. Defer (); Simulates a request $timeout (function () { d.resolve ([ {item: ", Done:false}, ... ]) },3000); return d.promise; } This.addtodo = function (item) { This.todos.push ({item:item, done:false}); } )

JBoss is a very powerful Java EE application Server, but this powerful feature also brings complexity. The author of this article, Marcus Zarra, analyzes how to configure multiple databases and data sources in JBoss. Configure a data source The default setup process for JBoss is a total of three configuration options: all, default, and minimum (minimal). If you

The default is FalseNBSP; N test-after-use If set to True connection will be tested with the House-keeping-test-sql set before closing (putting back the connection pool) if the test does not pass connection will be discarded. The default value is FalseNBSP; ? Unlike other connection pooling features, Proxool does not provide a set method. All features have to be info.setproperty ("Proxool.jmx", "false"), NBSP; ?
