Application writers may find them more convenient than calling **SQLSetDescField** or **SQLGetDescField**. These functions are called *concise* functions because they perform a number of functions, including setting or getting descriptor fields. Some concise functions let an application set or retrieve several related descriptor fields in a single function call. Concise functions can be called without first retrieving a descriptor handle for use as an argument. These functions work with the descriptor fields associated with the statement handle that they are called on. The concise functions **SQLBindCol** and **SQLBindParameter** bind a column or parameter by setting the descriptor fields that correspond to their arguments. Each of these functions performs more tasks than simply setting descriptors. **SQLBindCol** and **SQLBindParameter** provide a complete specification of the binding of a data column or dynamic parameter. An application can, however, change individual details of a binding by calling **SQLSetDescField** or **SQLSetDescRec** and can completely bind a column or parameter by making a series of suitable calls to these functions. The concise functions **SQLColAttribute**, **SQLDescribeCol**, **SQLDescribeParam**, **SQLNumParams**, and **SQLNumResultCols** retrieve values in descriptor fields. **SQLSetDescRec** and **SQLGetDescRec** are concise functions that, with one call, set or get multiple descriptor fields that affect the data type and storage of column or parameter data. **SQLSetDescRec** is an effective way to change the binding of column or parameter data in one step. **SQLSetStmtAttr** and **SQLGetStmtAttr** serve as concise functions in some cases.
