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

The Standard tSQLTemplateFilterRows component belongs to the ELT family.

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

Basic settings

Database Type

Select the type of database you want to work on from the drop down list.

Component List

Select the relevant DB connection component in the list if you are using more than one connection in the current Job.

Database name

Name of the database.

Source table name

Name of the table holding the data you want to filter.

Target table name

Name of the table you want to write the filtered data in.

Schema and Edit schema

A schema is a row description, it defines the number of fields that will be processed and passed on to the next component. The schema is either built-in or remote in the Repository.

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.

 

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 Job flowcharts. Related topic: see Talend Studio User Guide.

Where condition

Use a WHERE clause to set the criteria that you want the rows to meet.

You can use the WHERE clause to select specific rows from the table that match specified criteria or conditions.

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

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.

QUERY: the 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.
