MDAC 2.5 SDK - ODBC Programmer's Reference
Chapter 20: Function Summary
The following table lists ODBC functions, grouped by type of task, and includes the conformance designation and a brief description of the purpose of each function. For more information about conformance designations, see "ODBC and the Standard CLI" in Chapter 1, "Introduction to ODBC." For more information about the syntax and semantics for each function, see Chapter 21, "ODBC API Reference."
An application can call the SQLGetInfo function to obtain conformance information about a driver. To obtain information about support for a specific function in a driver, an application can call SQLGetFunctions.

| SQLPutData | ISO 92 | Sends part or all of a data value for a parameter. (Useful for long data values.) | |
| Retrieving results and information about results | SQLRowCount | ISO 92
|
Returns the number of rows affected by an insert, update, or delete request.
Returns the number of columns in the result set. |
| SQLDescribeCol | ISO 92 | Describes a column in the result set. | |
| SQLColAttribute | ISO 92 | Describes attributes of a column in the result set. | |
| SQLBindCol | ISO 92 | Assigns storage for a result column and specifies the data type. | |
| SQLFetch | ISO 92 | Returns multiple result rows. | |
| SQLFetchScroll | ISO 92 | Returns scrollable result rows. | |
| SQLGetData | ISO 92 | Returns part or all of one column of one row of a result set. (Useful for long data values.) | |
| SQLSetPos | ODBC | Positions a cursor within a fetched block of data and allows an application to refresh data in the rowset or to update or delete data in the result set. | |
| SQLBulkOperations | ODBC | Performs bulk insertions and bulk bookmark operations, including update, delete, and fetch by bookmark. | |
| SQLMoreResults | ODBC | Determines whether there are more result sets available and, if so, initializes processing for the next result set. | |
| SQLGetDiagField | ISO 92 | Returns additional diagnostic information (a single field of the diagnostic data structure). | |
