Data Source Management for ColdFusion

Last update:

May 18, 2026

A data source is a complete database configuration that uses a JDBC driver to communicate with a specific database. In Adobe ColdFusion, you configure a data source for each database that you want to use. After you configure a data source, ColdFusion can then communicate with that data source through JDBC.

For basic information on data sources and connecting to databases, click Resources in the ColdFusion Administrator, and then select Getting Started Experience.

About JDBC

The following table describes the four types of JDBC drivers:

Type	Name	Description
1	JDBC-ODBC bridge	Translates JDBC calls to ODBC calls, and sends them to the ODBC driver. Advantages: Allows access to many different databases.Disadvantages: The ODBC driver, and possibly the client database libraries, must reside on the ColdFusion server computer. Performance is slower than other JDBC driver types.Adobe does not recommend this driver type unless your application requires DBMS-specific features.
2	Native-API/partly Java driver	Converts JDBC calls to database-specific calls.Advantages: Better performance than Type 1 driver.Disadvantages: The client database libraries of the vendor must reside on the same computer as ColdFusion. ColdFusion includes a Type 2 driver for use with Microsoft Access Unicode databases.
3	JDBC-Net pure Java driver	Translates JDBC calls to the middle-tier server, which then translates the request to the database-specific native-connectivity interface.Advantages: The database libraries of vendors are not required client computer. Can be tailored for small size (faster loading).Disadvantages: Database-specific code must be executed in the middle tier. ColdFusion includes an ODBC socket Type 3 driver for use with Microsoft Access databases and ODBC data sources.
4	Native-protocol/all-Java driver	Converts JDBC calls to the network protocol used directly by the database.Advantages: Fast performance. No special software needed on the computer on which you run ColdFusion.Disadvantages: Many of these protocols are proprietary, requiring a different driver for each database. ColdFusion includes Type 4 drivers for many DBMSs; however, not all DBMSs are supported in ColdFusion Standard Edition.

JDBC drivers are stored in JAR files. For example, the JDBC drivers that are supplied with ColdFusion are in the drivers.jar file. If you are using another JDBC driver, you must store it in the ColdFusion classpath. For example, _cf_root/cfusion/lib (server configuration) or cf_webapp_root/WEB-INF/cfusion/lib (JEE configuration).

Supplied drivers

The following table lists the database drivers supplied with ColdFusion and where you can find more information about them:

To see a list of database versions that ColdFusion supports, go to https://helpx.adobe.com/pdf/coldfusion2018-support-matrix.pdf

When running in the JEE configuration, the ColdFusion Administrator also lets you configure a data source that connects to a JNDI data source. A Java Naming and Directory Interface (JNDI) data source is equivalent to a ColdFusion data source, except you define it by using your J2EE application server. After it's defined, ColdFusion applications use it as they would any data source. For information on defining a JNDI data source, see Connecting to JNDI data sources .

Adding data sources

The ColdFusion Administrator organizes information about all ColdFusion server database connections in a single location. In addition to adding data sources, you can use the Administrator to specify changes to your database configuration, such as relocation, renaming, or changes in security permissions.

Adding data sources in the Administrator

You use the ColdFusion Administrator to quickly add a data source for use in your ColdFusion applications. When you add a data source, you assign it a data source name (DSN) and set all information required to establish a connection.

ColdFusion includes data sources that are configured by default. You do not need the following procedure to work with these data sources.

In the ColdFusion Administrator, select Data & Services > Data Sources.
Under Add New Data Source, enter a data source name; for example, MyTestDSN. The following names are reserved; you cannot use them for data source names:
- service
- jms_provider
- comp
- jms
Select a driver from the drop-down list; for example, Microsoft SQL Server.
Click Add.A form for additional DSN information appears. The available fields in this form depend on the driver that you selected.
In the Database field, enter the name of the database.
In the Server field, enter the network name or IP address of the server that hosts the database, and enter any required Port value. For example, the bullwinkle server on the default port.
If your database requires login information, enter your user name and password.
The omission of required user name and password information is a common reason why a data source fails to verify.
(Optional) Enter a Description.
(Optional) Click Show Advanced Settings to specify any ColdFusion specific settings; for example, to configure which SQL commands can interact with this data source.
Click Submit to create the data source. ColdFusion automatically verifies that it can connect to the data source.
(Optional) To verify this data source later, click the verify icon in the Actions column.
To check the status of all data sources available to ColdFusion, click Verify All Connections.

Specifying connection string arguments

The ColdFusion Administrator lets you specify connection-string arguments for data sources. In the Advanced Settings page, use the Connection String field to enter name-value pairs separated by a semicolon. For more information, see the documentation for your database driver.

The cfquery connectstring attribute is no longer supported.

Guidelines for data sources

When you add data sources to ColdFusion, keep in mind the following guidelines:

Data source names must be all one word.
Data source names can contain only letters, numbers, hyphens, and the underscore character (_).
Data source names must not contain special characters or spaces.
Although data source names are not case sensitive, use a consistent capitalization scheme.
Depending on the JDBC driver, connection strings and JDBC URLs might be case sensitive.
Use the Administrator to verify that ColdFusion can connect to the data source.
A data source must exist in the ColdFusion Administrator before you use it on an application page to retrieve data.

Connection Issues

Provide validationQuery (to validate the connection) before executing the query in the Advanced Settings page.

validationQuery has to be used with caution as it can result in performance issues.

Click OK.

Troubleshooting SQL Server connections

If you are having trouble establishing a connection to SQL Server, review the following considerations:

If you installed SQL Server using a server name other than the default, use your chosen domain\servername wherever there is reference to (local). The following situations can cause a Connection Refused error:
- If you specified authentication information in SQL Server, ensure that you have not defined a user name and password in the ColdFusion data source.
- You are running a connection-limited version of SQL Server and the request exceeds the limit for TCP/IP connections. You can prevent this exception by setting the Limit Connections and Restrict Connections To options in ColdFusion Administrator on the Advanced Settings page for the data sources, and specifying a number less than the SQL Server maximum.
SQL Server does not enable the TCP/IP protocol. This problem can happen when SQL Server is on the same computer as ColdFusion. To fix this problem, perform the following steps:
1. In SQL Server Enterprise Manager, right-click on the name of your SQL Server and click Properties.
2. Click Network Configuration and the General Tab.
3. Move TCP/IP from the Disabled Protocols section to the Enabled Protocols section.
4. Click OK.
5. Restart the SQL Server services.
6. Verify your data source.
If you have are having trouble connecting, consider using mixed-mode authentication for SQL Server (Windows and SQL) and removing the user name and password from the ColdFusion data source.

Connecting to MySQL

To see a list of MySQL versions that ColdFusion supports, go to https://helpx.adobe.com/pdf/coldfusion2018-support-matrix.pdf

Support for MySQL (Enterprise and Commercial), Oracle11g, DB2v9.5, Informix 11, SQL Server 2008

For Oracle databases, if you want to filter the retrieval of column names or indexes for a particular schema, then the schema name must be provided along with the table name in the table attribute. In this case, the format of the table attribute value is: schemaname.tablename.

Improved performance
IPv6 Address Support
Querytimeout connection option to set default query timeout value. For details, see New querytimeout connection option.

Note: Timestamp Milliseconds are rounded off during insert on SQL Server 2008 and using Connect for JDBC driver version 4.2. This is a known issue. Read this article. As a workaround, specify the parameter DateTimeInputParameterType=dateTime in the connection string.

Creating a data source in MySQL

To create a MySQL Enterprise ColdFusion data source, select the driver type as MySQL(Datadirect) from the drivers pop up menu in ColdFusion Administrator.

The MySQL5 Enterprise database sometimes requires access permission for all users who try to connect to it, if the access permission is not specified during configuration.

To grant the required permission, you can use the command: grant all on . to 'root'@'%' identified by 'admin';. Replace root and admin by MYSQL username and MYSQL password, respectively. A new admin API method, setMySQL_DD has been added, which lets you create a MySQL DataDirect data source.

New querytimeout connection option

Following is the description of querytimeout and pagetimeout from the DataDirect documentation: "When the page time-out is much higher and the query times out, an exception is thrown to indicate that the query has timed out. Similarly, if the query timeout is much higher and page times out, an exception is thrown to indicate the page has timed out. However, when a page times out while a query is executing, the page times out only after the query's execution is complete." A new argument qtimeout has been added to the following methods in the Administrator API:

setDB2()
setMySQL_DD()
setOracle()
setInformix()
setMSSQL()
The qtimeout option is not supported by all databases.
