    • Techniques to dynamically select data sources for users and to direct queries for the users to the proper data sources. Initially, user information (e.g., user name) for each user is received and used to determine a data source designated for the user. The designated data source may be determined via a look-up table or by running a query with the user information to obtain the identity (e.g., the logical name) of the data source. A data source variable for each user can then be set to the identity of the designated data source. Thereafter, queries for each user are directed to the user's designated data source by determining database connection information for the designated data source based on the data source variable and using this information to direct the queries.
    • 为用户动态选择数据源的技术,并将用户的查询引导到正确的数据源。 最初,接收每个用户的用户信息(例如,用户名),并用于确定为用户指定的数据源。 指定的数据源可以通过查找表来确定,或者通过运行具有用户信息的查询来获得数据源的身份(例如,逻辑名称)。 然后可以将每个用户的数据源变量设置为指定数据源的标识。 此后,通过基于数据源变量确定指定数据源的数据库连接信息并使用该信息来指导查询,将针对每个用户的查询定向到用户的指定数据源。
