IBPhoenix Open Source ODBC Driver (aka Firebird ODBC driver)

Type ODBC Driver
 Usage Driver=Firebird/InterBase(r) driver
 Manufacturer IBPhoenix
More info and driver downloads

Set example values

Local database

    
DRIVER=Firebird/InterBase(r) driver;UID=SYSDBA;PWD=masterkey;
DBNAME=C:\database\myData.fdb;
 
 

Remote connection

    
DRIVER=Firebird/InterBase(r) driver;UID=SYSDBA;PWD=masterkey;
DBNAME=MyServer:C:\database\myData.fdb;

The default TCP/IP port 3050 will be used.

 
 

Specifying TCP/IP port number

    
DRIVER=Firebird/InterBase(r) driver;UID=SYSDBA;PWD=masterkey;
DBNAME=MyServer/3051:C:\database\myData.fdb;
 
 

Using alias (aliases.conf)

    
DRIVER=Firebird/InterBase(r) driver;UID=SYSDBA;PWD=masterkey;DBNAME=aliasname;

Example record in aliases.conf, aliasname = C:\database\myData.fdb

 
 

Using alias (aliases.conf) for remote connections

    
DRIVER=Firebird/InterBase(r) driver;UID=SYSDBA;PWD=masterkey;
DBNAME=MyServer/3051:aliasname;
 
 

Specifying dialect

SQL dialects were introduced in InterBase 6.0, to support a number of new SQL features including delimited identifiers.

    
DRIVER=Firebird/InterBase(r) driver;UID=SYSDBA;PWD=masterkey;
DBNAME=C:\database\myData.fdb;DIALECT=3;

DIALECT=1 - Parser processes as it did in InterBase V5.

DIALECT=2 - Transitional flagger. InterBaseV6, and Firebird flags ambiguous SQL constructs and issues an error or warning message.

DIALECT=3 - Parser processes anything delimited by single quotes as string constants and any thing delimited by double quotes as SQL delimited identifiers.

 
 

Autoquote identifiers

The driver will quote (") your table names in SQL statements automatically.

    
DRIVER=Firebird/InterBase(r) driver;UID=SYSDBA;PWD=masterkey;
DBNAME=C:\database\myData.fdb;AUTOQUOTED=YES;

'SELECT A.Field FROM Table A' will be transformed into 'SELECT "A.Field" FROM "Table" A'

Be aware that upper case SQL keywords must be used, ie SELECT and FROM etc, not Select and From, else transformation will fail.

 
 

Read Only connection

    
DRIVER=Firebird/InterBase(r) driver;UID=SYSDBA;PWD=masterkey;
DBNAME=C:\database\myData.fdb;READONLY=YES;
 
 

Return with error on locking conflict

    
DRIVER=Firebird/InterBase(r) driver;UID=SYSDBA;PWD=masterkey;
DBNAME=C:\database\myData.fdb;NOWAIT=YES;

Normally the transaction will wait if it encounters a lock conflict. This connection string will cause an error instead.

 
 

.NET Framework Data Provider for ODBC

Type .NET Framework Wrapper Class Library
 Usage System.Data.Odbc.OdbcConnection
 Manufacturer Microsoft
More info and wrapper class library downloads

Set example values

Use an ODBC driver from .NET

    
Driver={any odbc driver's name};OdbcKey1=someValue;OdbcKey2=someValue;

See the respective ODBC driver's connection strings options. The .net OdbcConnection will just pass on the connection string to the specified ODBC driver. Read more here.
