Functions for setting and retrieving environment attributes

To specify a new value for an environment attribute, call SQLSetEnvAttr(). To obtain the current value of an environment attribute, call SQLGetEnvAttr().

Attributes on an environment handle affect the behavior of all Db2 ODBC functions within that environment. You must set environment attributes before you allocate a connection handle. Because Db2 ODBC allows you to allocate only one environment handle, environment attributes affect all Db2 ODBC functions that your application calls.
