Database Write Snaps output all records of a batch (as configured in your account settings) to the error view if the write fails during batch processing.



Settings

Label


Required. The name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.

Schema name 


Required. The database schema name. Selecting a schema filters the Table name list to show only those tables within the selected schema. The property is suggestible and retrieves available database schemas during suggest values.

Note

The values can be passed using the pipeline parameters but not the upstream parameter.

Example: public

Default value: [None]

Table name


Required. The table on which to execute the insert operation.

Note

The values can be passed using the pipeline parameters but not the upstream parameter.

Example: emp

Default value: [None]

Create table if not present


Whether the table should be automatically created if not already present.

Note
Using this option creates a table with all columns of type STRING


Default value:  Not selected

Truncate data


Truncate the existing data before performing the data load. With the Bulk Update Snap, instead of executing truncate and then update, using a Bulk Insert Snap would be faster.

Default value:  Not selected

Maximum error count


Required. The maximum number of rows that can fail before the bulk load operation is stopped.

Example: 10

Default value: 0

Truncate columns


Truncate column values that are larger than the maximum column length in the table.
Default value:  Selected

Additional options


Additional options to be passed to the COPY command. See Copy Parameters for the available options.

Default value: [None]

Note

Instead of building multiple Snaps with inter dependent DML queries, it is recommended to user the Multi Execute Snap.
In a scenario where the downstream Snap does depend on the data processed on an Upstream Database Bulk Load Snap, use the Script Snap to add delay for the data to be available.

For example, when performing a create, insert and a delete function sequencially on a pipeline, using a Script Snap helps in create a delay between the insert and delete function or otherwise it may so happen that the delete function is triggered even before inserting the records on the table.
