ODBC


Standard:


"driver={IBM DB2 ODBC DRIVER};Database=myDbName;hostname=myServerName;port=myPortNum;protocol=TCPIP; uid=myUserName; pwd=myPwd"


Sybase
ODBC


Standard Sybase System 12  or 12.5) Enterprise Open Client:


"Driver={SYBASE ASE ODBC Driver};Srvr=Aron1;Uid=username;Pwd=password"


Standard Sybase System 11:


"Driver={SYBASE SYSTEM 11};Srvr=Aron1;Uid=username;Pwd=password;"
Do you know a userguide for Sybase System 11, 12, 12.5? E-mail the URL to connectionstrings.com now!! >>
Intersolv 3.10:


"Driver={INTERSOLV 3.10 32-BIT Sybase};Srvr=Aron1;Uid=username;Pwd=password;"


Sybase SQL Anywhere  former Watcom SQL ODBC driver):


"ODBC; Driver=Sybase SQL Anywhere 5.0; DefaultDir=c:\dbfolder\;Dbf=c:\mydatabase.db;Uid=username;Pwd=password;Dsn="""""
Note! The two double quota following the DSN parameter at the end are escaped quotas  VB syntax), you may have to change this to your language specific escape syntax. The empty DSN parameter is indeed critical as not including it will result in error 7778.


Read more in the Sybase SQL Anywhere User Guide >>
OLE DB


Adaptive Server Anywhere  ASA):


"Provider=ASAProv;Data source=myASA"
Read more in the ASA User Guide >>
Adaptive Server Enterprise  ASE) with Data Source .IDS file:


"Provider=Sybase ASE OLE DB Provider; Data source=myASE"
Note that you must create a Data Source .IDS file using the Sybase Data Administrator. These .IDS files resemble ODBC DSNs.
Adaptive Server Enterprise  ASE):


"Provider=Sybase.ASEOLEDBProvider;Srvr=myASEserver,5000;Catalog=myDBname;User Id=username;Password=password"
- some reports on problem using the above one, try the following as an alternative -


"Provider=Sybase.ASEOLEDBProvider;Server Name=myASEserver,5000;Initial Catalog=myDBname;User Id=username;Password=password"
This one works only from Open Client 12.5 where the server port number feature works,燼llowing fully qualified connection strings to be used without defining燼ny .IDS Data Source files.
AseConnection  .NET)


Standard:


"Data Source=’myASEserver’;Port=5000;Database=’myDBname’;UID=’username’;PWD=’password’;"


Declare the AseConnection:


C#:
using Sybase.Data.AseClient;
AseConnection oCon = new AseConnection );
oCon.ConnectionString="my connection string";
oCon.Open );


VB.NET:
Imports System.Data.AseClient
Dim oCon As AseConnection = New AseConnection )
oCon.ConnectionString="my connection string"
oCon.Open )


Informix
ODBC


Informix 3.30:


"Dsn=’’;Driver={INFORMIX 3.30 32 BIT};Host=hostname;Server=myserver;Service=service-name;Protocol=olsoctcp;Database=mydb;UID=username;PWD=myPwd


Informix-CLI 2.5:


"Driver={Informix-CLI 2.5  32 Bit)};Server=myserver;Database=mydb;Uid=username;Pwd=myPwd"


OLE DB


IBM Informix OLE DB Provider:


"Provider=Ifxoledbc.2;password=myPw;User ID=myUser;Data Source=dbName@serverName;Persist Security Info=true"


Ingres
ODBC


DSN-less


"Provider=MSDASQL.1;DRIVER=Ingres;SRVR=xxxxx;DB=xxxxx;Persist Security Info=False;uid=xxxx;pwd=xxxxx;SELECTLOOPS=N;Extended Properties="""SERVER=xxxxx;DATABASE=xxxxx;SERVERTYPE=INGRES""


Mimer SQL
ODBC


Standard Security:


"Driver={MIMER};Database=mydb;Uid=myuser;Pwd=mypw;"


Prompt for username and password:


"Driver={MIMER};Database=mydb;"


Lightbase
Standard


Standard:


"user=USERLOGIN;password=PASSWORD;UDB=USERBASE;server=SERVERNAME"


PostgreSQL
Core Labs PostgreSQLDirect  .NET)


Standard:


"User ID=root; Password=pwd; Host=localhost; Port=5432; Database=testdb;Pooling=true; Min Pool Size=0; Max Pool Size=100; Connection Lifetime=0"

DSN
ODBC


DSN:


"DSN=myDsn;Uid=username;Pwd=;"


File DSN:


"FILEDSN=c:\myData.dsn;Uid=username;Pwd=;"


Firebird
ODBC - IBPhoenix Open Source


Standard:


"DRIVER=Firebird/InterBase r) driver;UID=SYSDBA;PWD=masterkey;DBNAME=D:\FIREBIRD\examples\TEST.FDB"
IBPhoenix ODBC; More info, download etc >>
.NET - Firebird .Net Data Provider


Standard:


"User=SYSDBA;Password=masterkey;Database=SampleDatabase.fdb;DataSource=localhost;Port=3050;Dialect=3;Charset=NONE;Role=;Connection lifetime=15;Pooling=true;MinPoolSize=0;MaxPoolSize=50;Packet Size=8192;ServerType=0"
Firebird ADO.NET project >>

Excel
ODBC


Standard:


"Driver={Microsoft Excel Driver  *.xls)};DriverId=790;Dbq=C:\MyExcel.xls;DefaultDir=c:\mypath;"
TIP! SQL syntax: "SELECT * FROM [sheet1$]" - i.e. worksheet name followed by a "$" and wrapped in "[" "]" brackets.
OLE DB


Standard:


"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\MyExcel.xls;Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1"""
"HDR=Yes;" indicates that the first row contains columnnames, not data
"IMEX=1;" tells the driver to always read "intermixed" data columns as text
TIP! SQL syntax: "SELECT * FROM [sheet1$]" - i.e. worksheet name followed by a "$" and wrapped in "[" "]" brackets.
Text
ODBC


Standard:


"Driver={Microsoft Text Driver  *.txt; *.csv)};Dbq=c:\txtFilesFolder\;Extensions=asc,csv,tab,txt;"


OLE DB


Standard:


"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\txtFilesFolder\;Extended Properties=""text;HDR=Yes;FMT=Delimited"""
"HDR=Yes;" indicates that the first row contains columnnames, not data
DBF / FoxPro
ODBC


standard:


"Driver={Microsoft dBASE Driver  *.dbf)};DriverID=277;Dbq=c:\mydbpath;"


OLE DB, OleDbConnection  .NET)

AS/400
OLE DB


IBM Client Access OLE DB provider:


"PROVIDER=IBMDA400; DATA SOURCE=MY_SYSTEM_NAME;Uid=myUserName;Pwd=myPwd"
Where MY_SYSTEM_NAME is the name given to the system connection in OperationsNavigator
ODBC


IBM Client Access ODBC driver:


"Driver={Client Access ODBC Driver  32-bit)};System=my_system_name;Uid=myUserName;Pwd=myPwd"
Exchange
OLE DB


Exchange OLE DB provider:


"ExOLEDB.DataSource"
Specify store in the connection open command like this: conn.open "http://servername/mypublicstore"

Visual FoxPro
OLE DB, OleDbConnection  .NET)


Database container  .DBC):


"Provider=vfpoledb.1;Data Source=C:\MyDbFolder\MyDbContainer.dbc;Collating Sequence=machine"


Free table directory:


"Provider=vfpoledb.1;Data Source=C:\MyDataDirectory\;Collating Sequence=general"
