IfFunctionIdis SQL_API_ODBC3_ALL_FUNCTIONS,SupportedPtrpoints to a SQLSMALLINT array with a number of elements equal to SQL_API_ODBC3_ALL_FUNCTIONS_SIZE. This array is treated by the Driver Manager as a 4,000-bit bitmap that can be used to determine whether an ODBC 3*.x* or earlier...

SQL_DESC_TYPE_NAME (ODBC 1.0) CharacterAttributePtr Data source-dependent data type name; for example, "CHAR", "VARCHAR", "MONEY", "LONG VARBINARY", or "CHAR ( ) FOR BIT DATA". If the type is unknown, an empty string is returned. SQL_DESC_UNNAMED (ODBC 3.0) NumericAttributePtr SQL...
For example, if Attribute is SQL_ATTR_CONCURRENCY and ValuePtr is SQL_CONCUR_ROWVER, and if the data source does not support this, the driver substitutes SQL_CONCUR_VALUES and returns SQL_SUCCESS_WITH_INFO. To determine the substituted value, an application calls SQLGetStmtAttr. The format ...
