摘要：
Embodiments are provided to calculate and provide information based in part on a defined expression. In an embodiment, a database system can be configured to include a number of calculated columns as part of a database table structure. The database system can be configured to present a calculated result based in part on a determined result type. In one embodiment, a database system can be configured to enable calculated columns to be defined on a table of a database, wherein a component can be used to evaluate an expression associated with a column calculation to determine a proper result type. The proper result type can be stored and used when presenting a result of the calculation. Other embodiments are available.
