# SQLAllocEnv Function
**Conformance**  
 Version Introduced: ODBC 1.0 Standards Compliance: Deprecated  
  
 **Summary**  
 In ODBC 3.*x*, the ODBC 2.*x* function **SQLAllocEnv** has been replaced by **SQLAllocHandle**. For more information, see [SQLAllocHandle Function](../../../odbc/reference/syntax/sqlallochandle-function.md).  
  
> [!NOTE]  
>  For more information about what the Driver Manager maps this function to when an ODBC 2.*x* application is working with an ODBC 3.*x* driver, see [Mapping Deprecated Functions](../../../odbc/reference/appendixes/mapping-deprecated-functions.md) in Appendix G: Driver Guidelines for Backward Compatibility.
