tSalesforceOutputBulk Standard properties - 6.5

Schema and Edit schema

A schema is a row description. It defines the number of fields (columns) to Repository. When you create a Spark Job, avoid the reserved word line when naming the fields.

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.

Click Sync columns to retrieve the schema from the previous component connected in the Job.

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.

Bulk File Path

Specify the path to the file to be generated.

Append

Select this check box to append new data at the end of the file if it already exists, instead of overwriting the existing data.

Ignore Null

Select this check box to ignore NULL values.

Click the [+] button to add lines as needed and specify the external ID fields in the input flow, the lookup relationship fields in the upsert module, the lookup module as well as the external ID fields in the lookup module.

• Column name of Talend Schema: the name of the external ID field in the input flow. It refers to the fields in the schema of the preceding component. Such columns are intended to match against the external ID fields specified in the External id name column, which are the fields of the lookup module specified in the Module name column.

• Lookup relationship field name: the name of the lookup relationship field. It refers to the lookup relationship fields of the module specified in the Module Name field in the Basic settings view of the tSalesforceBulkExec component and is intended to establish relationship with the lookup module specified in the Module name column in this table. For how to define the lookup relationship fields and how to provide their correct names in the Lookup relationship field name field, go to the Salesforce website and launch the Salesforce Data Loader application for proper actions and information.

• Module name: the name of the lookup module.

• Polymorphic: select this check box when and only when polymorphic fields are used for relationship mapping. You will get an error if you keep this check box cleared for a polymorphic field or select it for a field that is not polymorphic. For more information about the polymorphic fields, search polymorphic at http://www.salesforce.com/us/developer/docs/api_asynch/.

• External id name: the name of the external ID field in the lookup module specified in the Module name column.

tStatCatcher Statistics

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

Global Variables

NB_LINE: the number of rows read by an input component or transferred to an output component. This is an After variable and it returns an integer.

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio User Guide.

Usage rule

This component is more commonly used with the tSalesforceBulkExec component. Used together, they gain performance while feeding or modifying information in Salesforce.com.
