<title>Purpose</title>
37
<p>The purpose of the Erlang ODBC application is to provide the
38
programmer with an ODBC interface that has a Erlang/OTP touch and
39
feel. So that the programmer may concentrate on solving his/her
40
actual problem instead of struggling with pointers and memory
41
allocation which is not very relevant for Erlang. This user guide
42
will give you some information about technical issues and provide
43
some examples of how to use the Erlang ODBC interface.</p>
47
<title>Prerequisites</title>
48
<p>It is assumed that the reader is familiar with the Erlang
49
programming language, concepts of OTP and has a basic
50
understanding of relational databases and SQL.</p>
54
<title>About ODBC</title>
55
<p>Open Database Connectivity (ODBC) is a Microsoft standard for
56
accessing relational databases that has become widely used. The
57
ODBC standard provides a c-level application programming
58
interface (API) for database access. It uses Structured Query
59
Language (SQL) as its database access language.</p>
63
<title>About the Erlang ODBC application</title>
64
<p>Provides an Erlang interface to communicate with relational
65
SQL-databases. It is built on top of Microsofts ODBC interface and
66
therefore requires that you have an ODBC driver to the database
67
that you want to connect to. The Erlang ODBC application is designed
68
using the version 3.0 of the ODBC-standard, however using the option
69
<c>{scrollable_cursors, off} </c> for a connection has been known
70
to make it work for at least some 2.X drivers.</p>
