Installing and Configuring the ODBC Driver for Mac OS¶
Similar to Windows, Mac OS utilizes named data sources (DSNs) for connecting ODBC-based client applications to Snowflake.
In this Topic:
The Snowflake ODBC driver for Mac requires iODBC, which is available for download from:
To install iODBC:
- After downloading iODBC, double-click on the downloaded .dmg file.
- Double-click on the installer file,
iODBC-SDK.pkg, and follow the prompts.
iODBC provides a GUI administrator tool for configuring drivers and DSNs; however, this tool has not been tested for use with Snowflake and, therefore, should not be used to create or manage DSNs. Use ODBC Manager instead.
ODBC Manager — Optional/Recommended¶
ODBC Manager is a GUI tool for configuring drivers and creating/managing DSNs. The tool is optional because you can also create DSNs manually by editing the appropriate
odbc.ini file. ODBC Manager is available from:
To install ODBC Manager:
- After downloading ODBC Manager, double-click on the downloaded .dmg file.
- Double-click on the installer file,
ODBC Manager.pkg, and follow the prompts.
The installer installs ODBC Manager in the
Step 1: Install the ODBC Driver¶
To install the Snowflake ODBC driver for Mac OS:
If you haven’t already downloaded the driver, download it now. For details, see Downloading the ODBC Driver.
Double-click on the downloaded .dmg file,
Double-click on the installer file,
snowflakeODBC_<version>.pkg, and follow the prompts.
You will likely be prompted for the administrator/sudo password for the machine on which you are installing the driver.
If you chose the default directory, the installer installs the ODBC driver files in the following directories:
Step 2: Configure the ODBC Driver¶
To configure the ODBC driver for Mac OS, create one or more data source (DSNs), which are stored in the following files, depending on the type of DSN you create:
- User DSNs:
- System DSNs:
To create a DSN, either use ODBC Manager or edit the appropriate
Creating a DSN Using ODBC Manager¶
To create a DSN in ODBC Manager:
Start ODBC Manager.
Click on User DSN or System DSN.
Click the Add button.
Select the driver to use (Snowflake) and click OK.
Enter the name of the DSN and optionally a description.
Create a Keyword/Value pair for each DSN parameter:
- Click Add to create a Keyword/Value pair.
- Select Keyword and replace it with the parameter name.
- Select Value and replace it with the value for the parameter.
Repeat this process for each parameter. For details about the parameters that can be set for each DSN, see ODBC Configuration and Connection Parameters.
Click OK to create the DSN.
If you are creating the first user or system DSN for the ODBC driver, ODBC Manager creates the
odbc.ini file in the corresponding directory for the type of DSN you are creating. If you are creating additional DSNs, ODBC Manager
adds entries for each DSN to the existing
Creating a DSN by Adding an Entry in the
If a user or system DSN has already been created for the driver, add the new entry to the
odbc.ini file that already exists in the corresponding directory for the type of DSN you are creating. If you are creating the first DSN
for the driver, you must manually create the
odbc.ini file and add the entry to the file.
For each DSN, specify:
- DSN name and driver name (Snowflake), in the form of
<dsn_name> = <driver_name>.
- Directory path and name of the driver file, in the form of
Driver = /opt/snowflake/snowflakeodbc/lib/universal/libSnowflake.dylib.
- Connection parameters, such as
uid(user login name). Any connection parameters you add to the DSN do not need to be specified in the ODBC connect string.
- Any additional parameters, such as default
Parameters are specified in the form of
<parameter_name> = <value>. For details about the parameters that can be set for each DSN, see ODBC Configuration and Connection Parameters.
The following example illustrates an
odbc.ini file containing two drivers,
[ODBC Data Sources] testodbc1 = Snowflake testodbc2 = Snowflake [testodbc1] Driver = /opt/snowflake/snowflakeodbc/lib/universal/libSnowflake.dylib Description = uid = peter server = abc123.snowflakecomputing.com role = sysadmin [testodbc2] Driver = /opt/snowflake/snowflakeodbc/lib/universal/libSnowflake.dylib Description = uid = mary server = abc123.snowflakecomputing.com role = analyst database = sales warehouse = analysis
Note the following:
- Both drivers in the example have a user login name and default roles.
testodbc2also has a default database and warehouse.
Step 3: Test the ODBC Driver¶
You can use the
iodbctest command line utility provided with iODBC to test the DSNs you create.
When prompted for the ODBC connect string, enter the required connection parameters (DSN name, server, user login name, and password), as well as any other parameters that you would like to enter as part of the connect string. The
connect string takes parameters in the form of
dsn=testodbc2, with each parameter separated by a semi-colon (
;) and no blank spaces. For the list of supported parameters, see
ODBC Configuration and Connection Parameters.
If you set the server and user login name in the DSN, the only required parameters in the connect string are the DSN name and user password.
