Hi,

It's an own UDF function:

//------------------------------------------------------------------------------
-----

int eMeL_DBKey2RowNum(char * str8bytes)
{
int * ipLow = (int *)(str8bytes + 4);
return *ipLow;
}
//------------------------------------------------------------------------------
-----

declare external function eMeL_DBKey2RowNum cstring(8)
returns integer by value
entry_point '_eMeL_DBKey2RowNum' module_name 'IB_eMeL.dll';

//------------------------------------------------------------------------------
-----

select eMeL_DBKey2RowNum(RDB$DB_KEY) as EMEL_ROWNUM from XXXTABLE;

//------------------------------------------------------------------------------
-----

Please read of limitations of RDB$DB_KEY (for example valid only in living
transaction).

eMeL
