Abstract
A method and system for retrieving data from a database over a network includes: generating an executable statement at a gateway in accordance with a macro language file, where the executable statement comprises one or more a parameter markers; passing the executable statement from the gateway to database software; and passing a value for each parameter marker from the gateway to the database software. The present invention allows the Net.Data gateway to support parameter markers in place of Net.Data variables. This allows the Net.Data gateway to take advantage of the dynamic Structured Query Language (SQL) statement caching feature available with conventional database systems. With the use of this invention, the execution of the SQL statements occurs more rapidly, saving resources and improving performance. Additionally, the Net.Data variables may be automatically replaced with parameter markers, with the Net.Data variables and their values maintained. This provides transparent support for parameter markers.
