tParseRecordSet – Docs for ESB 7.x

tParseRecordSet

Parses a recordset rather than individual records from a table.

The tParseRecordSet parses a set of
records from a database table or DB query and possibly returns single records.

tParseRecordSet Standard properties

These properties are used to configure tParseRecordSet running in the Standard Job framework.

The Standard
tParseRecordSet component belongs to the Databases family.

The component in this framework is available in all Talend
products
.

Basic settings

Prev. Comp. Column list

Set the column from the database that holds the recordset.

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: The schema is created
and stored locally for this component only. Related topic: see

Talend Studio User
Guide
.

 

Repository: The schema already
exists and is stored in the Repository, hence can be reused. Related
topic: see
Talend Studio User
Guide
.

 

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.

Attribute table

Set the position value of each column for single records from the
recordset.

Advanced settings

tStatCatcher Statistics

Select this check box to collect log data at the component level.

Global Variables

Global Variables

NB_LINE: the number of rows processed. 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

Usage rule

This component is used as intermediary component. It can be used
as start component but only input parameters are thus allowed.

Limitation

This component is mainly designed for a use with the SP component
Recordset feature.
