tCombinedSQLOutput properties

Component family

ELT/CombinedSQL

 

Function

tCombinedSQLOutput inserts records to an existing database table.

Purpose

tCombinedSQLOutput inserts records from the incoming flow to an existing database table.

Basic settings

Database Type

Select the database type.

 

Component list

Select the relevant DB connection component in the list if more than one connection is used for the current Job.

 

Table

Name of the target database table.

 

Schema

Name of the target database table's schema. This field has to be filled if the database is Oracle.

 

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. The schema is either Built-In or stored remotely in the Repository.

Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions.

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.

 

 

Built-in: You create and store the schema locally for this component only. Related topic: see Talend Studio User Guide.

 

 

Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Jobs. Related topic: see Talend Studio User Guide.

 

Action on data

Select INSERT from the list to insert the records from the incoming flow to the target database table.

Advanced settings

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at a 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 a Flow variable and it returns an integer.

QUERY: the SQL query statement being processed. This is a Flow variable and it returns a string.

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

This component is an intermediary component. The use of the corresponding connection and commit components is recommended when using this component to allow a unique connection to be open and then closed during the Job execution.
