# tSnowflakeConnection Opens a connection to Snowflake that can then be reused by other Snowflake components. Information noteNote: This component is not shipped with your Talend Studio by default. You need to install it using the Feature Manager. For more information, see [Installing features using the Feature Manager](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/install-features-to-talend-studio). ## tSnowflakeConnection Standard properties These properties are used to configure tSnowflakeConnection running in the Standard Job framework. The Standard tSnowflakeConnection component belongs to the Cloud family. The component in this framework is available in all Talend products. Information noteNote: This component is a specific version of a dynamic database connector. The properties related to database settings vary depending on your database type selection. For more information about dynamic database connectors, see [DB Generic components](https://help.qlik.com/talend/r/en-US/8.0/components/db-generic/db-generic-component). ## Basic settings | Properties | Description | | --- | --- | | Database | Select the desired database type from the list and click
Apply. | | Property Type | Select the way the connection details
will be set.

| | Account | In the Account field, enter, in double
quotation marks, the account name that has been assigned to you by Snowflake. | | Authentication Type | Set the authentication type.



Information noteNote: Before selecting the Key
Pair option, make sure you have set the key pair authentication
data in the Basic settings view of the tSetKeystore
component as follows.

  1. Leave the TrustStore type field unchanged.
  2. Set TrustStore file to "".
  3. Clear the TrustStore password field.
  4. Select Need Client authentication.
  5. Enter the path to the key store file in double quotation marks in the KeyStore file field (or click the […] button to the right of the KeyStore file field and navigate to the key store file).
  6. Enter the key store file password in the KeyStore password field.
  7. Clear the Check server identity option.
| | OAuth token endpoint | Enter OAuth 2.0 token endpoint.

This option is available when
OAuth 2.0 is selected from the
Authentication Type dropdown list. | | Client ID | Enter the client ID of your application.

This option is available when
OAuth 2.0 is selected from the
Authentication Type dropdown list. | | Client Secret | Enter the client secret of your application.

This option is available when
OAuth 2.0 is selected from the
Authentication Type dropdown list. | | Grant type | Set the grant type for retrieving the access token. Two options are
provided: Client Credentials and
Password.

Click [Client Credentials](https://tools.ietf.org/html/rfc6749#section-1.3.4) and [Resource Owner Password Credentials](https://tools.ietf.org/html/rfc6749#section-1.3.3) for related
information.

This option is available when OAuth
2.0 is selected from the Authentication
Type dropdown list. | | OAuth username | Enter the OAuth username.

This option is available when
Password is selected from the Grant
type dropdown list. | | OAuth password | Enter the OAuth password.

To enter the password, click the [...] button
next to the password field, enter the password between double quotes in the
pop-up dialog box, and then click OK to save the
settings.

This option is available when Password
is selected from the Grant type dropdown
list.

Information noteNote: OAuth password does not support spaces. | | Scope | Enter the scope. See [Scopes](https://docs.snowflake.com/en/user-guide/oauth-ext-overview.html#scopes) for related information.

This option is
available when OAuth 2.0 is selected from the
Authentication Type dropdown list. | | User Id | Enter your login name in double quotation marks. | | Password | Click the [...] button next to the
Password field, enter the password in double quotation
marks in the pop-up dialog box, and click OK.

This field
is available if Basic is selected from the
Authentication Type dropdown list. | | Key Alias | Enter the key pair alias in double quotation marks.

This field is
available if Key Pair is selected from the
Authentication Type dropdown list. | | Warehouse | Enter, in double quotation marks, the name of the
Snowflake warehouse to be used. This name is case-sensitive and is normally upper
case in Snowflake. | | Schema | Enter,
within double quotation marks, the name of the database schema to be used. This name
is case-sensitive and is normally upper case in Snowflake. | | Database | Enter, in double quotation
marks, the name of the Snowflake database to be used. This name is case-sensitive
and is normally upper case in Snowflake. | | Use or register a shared DB Connection | Select this checkbox to share
your database connection or fetch a database connection shared by a parent or
child Job, and in the Shared DB connection name field
displayed, enter the name for the shared database connection. This allows you
to share one single database connection (except the database schema setting)
among several database connection components from different Job levels that can
be either parent or child.

This option is
incompatible with the Use dynamic Job and Use an
independent process to run subJob options of the
tRunJob component. Using a shared connection together with a
tRunJob component with either of these two options enabled
will cause your Job to fail.

This checkbox is not available when the Specify a data source
alias checkbox is selected. | ## Advanced settings | Properties | Description | | --- | --- | | Auto Commit | Select this option to automatically commit the changes made to the current
database when the connection to the database is terminated.

This option is
selected by default.

Information noteNote: This option has no effect on the tSnowflakeOutput
and tSnowflakeRow components. | | Additional JDBC Parameters | Specify additional JDBC parameters for the
database connection created. | | Login Timeout | Specify the timeout period (in minutes)
of Snowflake login attempts. An error will be generated if no response is received
in this period. | | Role | Enter, in
double quotation marks, the default access control role to use to initiate the
Snowflake session.

This role must already exist and
has been granted to the user ID you are using to connect to Snowflake. If this field
is left empty, the PUBLIC role is automatically granted. For information about
Snowflake access control model, see [Understanding the Access Control
Model](https://docs.snowflake.net/manuals/user-guide/security-access-control.html). | | URL suffix | Enter, in double quotation marks, the Snowflake custom domain URL of your
choice. For more information about Snowflake URL formats, see [Standard account URLs](https://docs.snowflake.com/en/user-guide/organizations-connect#standard-account-urls).

For Snowflake
components other than tSnowflakeConnection, this field is available when you
select Use This Component from the Connection
Component drop-down list in the Basic
settings view. | | tStatCatcher Statistics | Select this checkbox to gather the Job processing metadata at the Job level
as well as at each component level. | ## Global variables | Variables | Description | | --- | --- | | ERROR\_MESSAGE | The error message generated by the component when an error
occurs. This is an After variable and it returns a string. | ## Usage | Usage guidance | Description | | --- | --- | | **Usage rule** | This component is more commonly used with other Snowflake components. It
creates a Snowflake connection and works with other subJobs that reuse this
connection using a Trigger link. | | Tracing Snowflake JDBC logs | If you wish to merge the Snowflake JDBC driver logs with the logs of the current Job, add this JVM argument, -Dnet.snowflake.jdbc.loggerImpl=net.snowflake.client.log.JDK14Logger, in the Run > Advanced settings tab of the Job you are running. | **Related concepts** * [Aggregating Snowflake data using ELT components](https://help.qlik.com/talend/en-US/components/8.0/snowflake/teltinput-teltmap-tsnowflakeinput-tlogrow-aggregating-snowflake-data-using-context-variables-as-table-and-connection-names "This scenario shows you an example of aggregating Snowflake data from two source tables STUDENT and TEACHER to one target table FULLINFO using the ELT components.") * [Writing data into and reading data from a Snowflake table](https://help.qlik.com/talend/en-US/components/8.0/snowflake/tsnowflakeconnection-tsnowflakerow-tsalesforceconnection-writing-data-into-and-reading-data-from-snowflake-table-standard-component "Here is an example of using Talend Snowflake components to connect to Snowflake, create a Snowflake table, write data into the table, then read data from this table, finally close the connection to Snowflake.")
