Data connections

The result of initialization is a data connection corresponding to one of the three AE data connection types: function, aggregate, and shaper or sizer. Each language reference guide contains sections corresponding to these three data connection APIs.

The data connection APIs are used to receive and return data with the database. The AE function API is used with SQL Table and Scalar Functions, the AE Aggregation API is used with SQL Aggregate Functions, and the AE Shaper or Sizer API is used with SQL Table-Function-Shapers and SQL Scalar-Function-Sizers.

The examples in Scalar functions examples, Simple table function examples, and Table function (simulated row function) examples all demonstrate the AE Function API. The Shapers and sizers examples demonstrate the AE Shaper or Sizer API. The Aggregate AE examples demonstrate the AE Aggregate API.
