Post by d***@hotmail.comI am new to Informix and I see ESQL/C is referred to a lot in documentation as a means to accesss an Informix database from an external application. Why should I use ESQL/C when I can just use ODBC or OLE to do the same?
Hi,
OLE and ODBC do not have a fame to have fast access, ESQL/C has a native access to Informix, therefore the most direct connection possible.
ESQL/C is C embedded, meaning this is a very fast language, consuming low level of hardware resource. If raw performance is critical for you, use ESQL/C, but the other hand of this is that programming in C is way more costly than any present time language.
