Select a type of database from the list and click
Apply.

Property Type

Select the way the connection details
will be set.

• Built-In: The connection details will be set
  locally for this component. You need to specify the values for all
  related connection properties manually.

• Repository: The connection details stored
  centrally in Repository > Metadata will be reused by this component. You need to click
  the […] button next to it and in the pop-up
  Repository Content dialog box, select the
  connection details to be reused, and all related connection
  properties will be automatically filled in.

This property is not available when other connection component is selected
from the Connection Component drop-down list.

Connection Component

Select the component that opens the database connection to be reused by this
component.

Account

In the Account field, enter, in double quotation marks, the account name
that has been assigned to you by Snowflake.

Select an AWS region or an Azure region from
the Snowflake Region drop-down list.

User Id and Password

Enter, in double quotation marks, your authentication

Table

Click the […] button and in the displayed wizard, select the Snowflake
table to be used.

Schema and Edit Schema

A schema is a row description. It defines the number of fields
(columns) to be processed and passed on to the next component. When you create a Spark
Job, avoid the reserved word line when naming the
fields.

Built-In: You create and store the schema locally for this component
only.

Repository: You have already created the schema and stored it in the
Repository. You can reuse it in various projects and Job designs.

If the Snowflake data type to
be handled is VARIANT, OBJECT or ARRAY, while defining the schema in the
component, select String for the
corresponding data in the Type
column of the schema editor wizard.

Click Edit
schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

• View schema: choose this
  option to view the schema only.

• Change to built-in property:
  choose this option to change the schema to Built-in for local changes.

• Update repository connection:
  choose this option to change the schema stored in the repository and decide whether
  to propagate the changes to all the Jobs upon completion. If you just want to
  propagate the changes to the current Job, you can select No upon completion and choose this schema metadata
  again in the Repository Content
  window.

Note that if the input value of any non-nullable primitive
field is null, the row of data including that field will be rejected.This component is end component of a data flow in your Job. It receives data from
other components via a

This
component offers the advantage of the dynamic schema feature. This allows you to
retrieve unknown columns from source files or to copy batches of columns from a source
without mapping each column individually. For further information about dynamic schemas,
see
Talend Studio

User Guide.

This
dynamic schema feature is designed for the purpose of retrieving unknown columns of a
table and is recommended to be used for this purpose only; it is not recommended for the
use of creating tables.

Output Action

Select the operation to insert, delete, update or merge
data in Snowflake tables.

The Upsert operation allows you to merge data in a Snowflake table
based on the data that is passed to tSnowflakeOutput. After selecting Upsert, select the column to be used as the join key
of this operation.

Additional JDBC Parameters

Specify additional JDBC parameters for the
database connection created.

Specify the timeout period (in minutes)
of Snowflake login attempts. An error will be generated if no response is received
in this period.

Tracing

Select the log level for the Snowflake JDBC driver. If
enabled, a standard Java log is generated.

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.

Select this check box to convert lowercase in the defined
table name and schema column names to uppercase. Note that unquoted
identifiers should match the Snowflake Identifier Syntax.

automatically quoted.

This property is not available when you select the
Manual Query check box.

For more information on the Snowflake Identifier Syntax,
see Identifier Syntax.

Select this check box to gather the Job processing metadata at the Job level
as well as at each component level.

The number of rows successfully processed. This is an After variable and it returns an
integer.
