![]() SAFEARRAYs are mapped to fixed-size arrays on the host computer. NET environments, arrays are SAFEARRAYs that contain information about their bounds and contain the data for the array elements. ![]() UDTs are useful when you want to create a single variable that records several related pieces of information.Īrray. You can combine variables of several different types to create UDTs. A UDT can contain an ordinary (fixed-size) array. Unlike recordsets, which must contain all of the formatting necessary to expose them to ADO applications, a UDT is just raw data and can therefore be faster than recordsets. Recordsets cannot be nested or contain arrays. Each column in the row can contain only a single data element. Recordsets allow TI to support what is effectively an array of a structure (or table in COBOL terminology) it even can support the special case of a structure that is a recordset containing only one row. A recordset object represents a set of records in a table. ![]() A recordset is the primary object used for retrieving and modifying tabular data by using ADO. A recordset contains all of the ADO information to make it manageable by any ADO application. A recordset provides a means of presenting and manipulating tabular data in a Microsoft ActiveX® Data Objects (ADO) environment. TI allows you to define this type of data as one of the following formats: In many cases, the input or output data that Transaction Integrator (TI) handles might be in tabular or array format.
