tOracleValidRows Standard properties

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

The Standard tOracleValidRows 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 in 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 DB Generic components.

Basic settings


Select the desired database type 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.

Regex pattern validation

  • Analyzed column: select from the schema list the column to analyze.

  • Custom pattern: select this check box to define manually your own customized regular expression against which you want to check the DB rows.
  • Patterns list: select from the pattern list the pattern against which you want to check the DB rows.

DQ rule validation

  • DQ rule list: select from the list the rule against which you want to check the DB rows.

  • Query type: Either Built-in or Repository.
    1. Built-in: fill in manually the query statement or build it graphically using SQLBuilder.
    2. Repository: select the relevant query stored in the Repository. The Query field is filled in accordingly.
  • Guess query: click the Guess Querry button to generate the query which corresponds to your table schema in the Query field.

  • Guess schema: click the Guess Schema button to retrieve the schema from the table.

  • Query: enter your DB query paying particular attention to properly sequence the fields in order to match the schema definition.

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 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, do the following if you want to share an existing connection between the parent Job and the child Job (for example, to share the connection created by the parent Job with the child Job).
  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 Sharing a database connection.

Connection Type

Drop-down list of available drivers.

DB Version

Select the Oracle version you are using.


Database server IP address.


Listening port number of DB server.


Name of the database.

Oracle schema

Name of the Oracle schema.

Username and Password

DB user authentication data.

To enter the password, click the [...] button next to the password field, enter the password in double quotes in the pop-up dialog box, 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. For more information about a component schema in its Basic settings tab, see Basic settings tab.


Repository: You have already created the schema and stored it in the Repository and thus reuse it when needed. For more information about a component schema in its Basic settings tab, see Basic settings tab.

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

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

Use cursor

Select this check box to specify the number of rows you want to work with at at a given time. This option optimises performance.

Trim all the String/Char columns

Select this check box to remove leading and trailing whitespace from all the String/Char columns.

Trim column

Remove leading and trailing whitespace from the defined columns.

Information noteNote:

Clear the Trim all the String/Char columns to enable Trim column.

No null values

Select this check box to improve the performance if there are no null values.

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 more information about variables, see Using contexts and variables.


Usage rule

This component can be used as a start or intermediary step. It requires an output flow.
