[erlang-questions] odbc DBMS

[Jan Jacobs]

Hi Rene,

Use the Erlang ODBC,  switching between DBs is easy, just change the 
connection string.
Look at  http://www.connectionstrings.com/ for the connection strings. 
See examples below:

SQL Server: ( MSSQL 2000, 2005 and 2008)
Str = "Driver={SQL 
Server};Server=JAN03;Database=TestDB;Uid=test;Pwd=testpassword;".
f(Ref), {ok,Ref} = (catch odbc:connect( Str, [{timeout, 75000}, 
{scrollable_cursors, off}] )).
{selected, ColList, ValueList} = (catch odbc:sql_query( Ref, "select * 
from tbl_system;", 45000 )).
odbc:disconnect( Ref ).

MySQL:
Str = "Driver={MySQL ODBC 3.51 
Driver};Server=JAN03;Port=3306;Database=TestDB;User=test;Password=testpassword;Option=3;".
f(Ref), {ok,Ref} = (catch odbc:connect( Str, [{timeout, 75000}, 
{scrollable_cursors, off}] )).
{selected, ColList, ValueList} = (catch odbc:sql_query( Ref, "select * 
from tbl_system;", 45000 )).
odbc:disconnect( Ref ).

Firebird:
Str = "Driver=Firebird/InterBase(r) 
driver;Uid=SYSDBA;Pwd=masterkey;DbName=C:\DeepBlue\TestDB.FDB".
f(Ref), {ok,Ref} = (catch odbc:connect( Str, [{timeout, 75000}, 
{scrollable_cursors, off}] )).
{selected, ColList, ValueList} = (catch odbc:sql_query( Ref, "select * 
from tbl_system;", 45000 )).
odbc:disconnect( Ref ).

Postgre:
Str = "Driver={PostgreSQL 
ANSI};Server=JAN03;Port=5432;Database=TestDB;Uid=test;Pwd=testpassword;".
f(Ref), {ok,Ref} = (catch odbc:connect( Str, [{timeout, 75000}, 
{scrollable_cursors, off}] )).
{selected, ColList, ValueList} = (catch odbc:sql_query( Ref, "select * 
from tbl_system;", 45000 )).
odbc:disconnect( Ref ).

I actively using SQL Server, MySQL,  Firebird.
I occasionally use Postgre  Oracle, Interbase, Access and Excel

Cheers
Jan
