tOracleInvalidRows Standard properties

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

The Standard tOracleInvalidRows component belongs to the Data Quality and the Databases families.

This component is available in Talend Data Management Platform, Talend Big Data Platform, Talend Real Time Big Data Platform, Talend Data Services Platform, Talend MDM Platform and Talend Data Fabric.

Information noteNote: This component is a specific version of a dynamic database connector. The properties related to database settings vary depending on your database type selection. For more information about dynamic database connectors, see Dynamic database components.

Basic settings

Database

Select a type of database from the list and click Apply.

Validation type

Either Regex pattern validation or DQ rule validation.

 

Regex pattern validation: Validate data in the database against regex patterns.

 

DQ rule validation: Validate data in the database against DQ rules.

Property type

Either Built-in or Repository.

 

Built-in: No property data stored centrally.

 

Repository: Select the repository file where Properties are stored. The fields that come after are pre-filled in using the fetched data.

Use an existing connection

Select this check box and in the Component List drop-down list, select the desired connection component to reuse the connection details you already defined.

Note that connections that are of WALLET type are for the tCreateTable component, the tOracleInput component, and the tOracleOutput component only. Make sure that the connection selected is not of the WALLET type to prevent possible errors.

Information noteNote: When a Job contains the parent Job and the child Job, if you need to share an existing connection between the two levels, for example, to share the connection created by the parent Job with the child Job, you have to:
  1. In the parent level, register the database connection to be shared in the Basic settings view of the connection component which creates that very database connection.

  2. In the child level, use a dedicated connection component to read that registered database connection.

For an example about how to share a database connection across Job levels, see Talend Studio User Guide.

Connection Type

Drop-down list of available drivers.

DB Version

Select the Oracle version you are using.

Host

Database server IP address.

Port

Listening port number of DB server.

Database

Username and Password

DB user authentication data.

To enter the password, click the [...] button next to the password field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

Schema and Edit schema

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

 

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 and thus reuse it when needed. Related topic: see Talend Studio User Guide.

Table Name

Enter the name of the table to be read.

Where clause

Enter a WHERE clause to define a row filter on the table.

You can use the WHERE clause to filter the rows you want to analyze in the table. This WHERE clause enables you then to retrieve valid and invalid data that match certain specified criteria or conditions.

Advanced settings

Additional JDBC Parameters

Specify additional connection properties for the DB connection you are creating. This option is not available if you have selected the Use an existing connection check box in the Basic settings.

Information noteNote:

You can press Ctrl+Space to access a list of predefined global variables.

Convert XML type to Java Type

Select this check box and then use the table to convert the types of the defined columns to Java types.

tStatCatcher Statistics

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.
