The IBM DB2 for i Load connector uses the Connect and Configure parameters to create a table of IBM DB2 for i data, which is then stored in your Snowflake cloud data warehouse. You do not need to use the Create Table component when using this connector, as the IBM DB2 for i Load component will create a new table or replace an existing table for you using the Destination parameters you define.
IBM DB2 for i Load supersedes any legacy IBM DB2 for i Query component you may have been using. If you are using IBM DB2 for i Query, Matillion recommends migrating to IBM DB2 for i Load for improved performance and functionality.
If the component requires access to a cloud provider (AWS, Azure, or GCP), it will use the cloud credentials associated with your environment to access resources. To stage data to Azure Blob Storage, the Azure credentials associated with your environment must be assigned the Storage Blob Data Contributor role. For more information, read User assigned with the Storage Blob Data Contributor role.

​

​
Connection URL
string

The URL for your chosen IBM DB2 for i database. The general pattern of the URL is jdbc:as400://<host>/<database>. Make appropriate substitutions for the <host> and <database> parameters in this URL.Although many parameters and options can be added to the end of the URL, it is generally easier to add them in the Connection Options property.
​
Connection Options
column editor
  • Parameter: A JDBC parameter supported by the database driver. The available parameters are explained in data model. Manual setup is not usually required, since sensible defaults are assumed.
  • Value: A value for the given parameter.
Click the Text Mode toggle at the bottom of the Connection Options dialog to open a multi-line editor that lets you add items in a single block. For more information, read Text mode.To use grid variables, select the Use Grid Variable checkbox at the bottom of the Connection Options dialog.
​
SSH Tunnel
drop-down
Select an SSH tunnel to use for connecting to your IBM DB2 for i database. Read SSH tunnels to learn how to create an SSH tunnel.
If selected, the Connection URL will be the data source that your secure tunnel connects to.

​
Configure

​
Load Type
drop-down
required
  • Full Load: Load all data from the data source on every pipeline run.
  • Incremental Load: Load only new or updated data since the last successful pipeline run using a high-water mark column.
​
Mode
drop-down
required
  • Basic: Configure data selection using the Data Source, Data Selection, Data Source Filter, Combine Filters, and Row Limit properties.
  • Advanced: Write your own SQL query using the SQL Query property.
  • Incremental: Use incremental data loading with a high-water mark column. Available when Load Type is set to Incremental Load.
​
SQL Query
code editor
Write an SQL query to retrieve your data. Only available for Snowflake destinations when Mode is set to Advanced.
​
Schema
drop-down
required
Select the schema to use when browsing available data sources.
​
Data Source
drop-down
required
Select the data source to query from. Available when Mode is set to Basic.
​
Data Selection
dual listbox
required
Select the columns to include from the data source. Available when Mode is set to Basic.
​
Data Source Filter
grid
Filter the rows returned from the data source. Available when Mode is set to Basic.
​
Combine Filters
drop-down
required
Choose how to combine multiple filters. Select AND to return rows matching all filters, or OR to return rows matching any filter. Available when Mode is set to Basic.
​
Row Limit
integer
The maximum number of rows to return from the data source. Leave blank to return all rows. Available when Mode is set to Basic.
​
High Water Mark Selection
drop-down
required
Select the column to use as the high-water mark for incremental loading. Available when Load Type is set to Incremental Load.

​
Destination

Select your cloud data warehouse.
​
Destination
drop-down
required
Select the destination for your data. This is either in Snowflake as a table or as files in cloud storage.
  • Snowflake: Load your data into a table in Snowflake. The data must first be staged via Snowflake or a cloud storage solution.
  • Cloud Storage: Load your data directly into files in your preferred cloud storage location. The format of these files can differ between source systems and will not have a file extension so we suggest inspecting the output to determine the format of the data.
​
Warehouse
drop-down
required
The Snowflake warehouse used to run the queries. The special value [Environment Default] uses the warehouse defined in the environment. Read Overview of Warehouses to learn more.
​
Database
drop-down
required
The Snowflake database to access. The special value [Environment Default] uses the database defined in the environment. Read Databases, Tables and Views - Overview to learn more.
​
Schema
drop-down
required
The Snowflake schema. The special value [Environment Default] uses the schema defined in the environment. Read Database, Schema, and Share DDL to learn more.
​
Table Name
string
required
The name of the table to be created in your Snowflake database. You can use a Table Input component in a transformation pipeline to access and transform this data after it has been loaded.
​
Load Strategy
drop-down
required
Define what happens if the table name already exists in the specified Snowflake database and schema.
  • Replace: If the specified table name already exists, that table will be destroyed and replaced by the table created during this pipeline run.
  • Truncate and Insert: If the specified table name already exists, all rows within the table will be removed and new rows will be inserted per the next run of this pipeline.
  • Fail if Exists: If the specified table name already exists, this pipeline will fail to run.
  • Append: If the specified table name already exists, then the data is inserted without altering or deleting the existing data in the table. It’s appended onto the end of the existing data in the table. If the specified table name doesn’t exist, then the table will be created, and your data will be inserted into the table.
​
Primary Keys
