Component family

Data Quality

 

Basic settings

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.

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

 

 

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 click the relevant connection component to reuse the connection details you already defined.

Note

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

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, 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.

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

 

 

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.

Note

Available only for Regex pattern validation.

Analyzed column

Select from the schema list the column to analyze.

Note

Available only for Regex pattern validation.

Custom pattern

Select this check box to define manually your own customized regular expression against which you want to check the DB rows.

Note

Available only for Regex pattern validation.

Patterns list

Select from the pattern list the pattern against which you want to check the DB rows.

Note

Available only for DQ rule validation.

DQ rule list

Select from the list the rule against which you want to check the DB rows.

Note

Available only for DQ rule validation.

Query type

Either Built-in or Repository:

  

Built-in: Fill in manually the query statement or build it graphically using SQLBuilder.

  

Repository: Select the relevant query stored in the Repository. The Query field are filled in accordingly.

Note

Available only for DQ rule validation.

Guess Query

Click the Guess Querry button to generate the query which corresponds to your table schema in the Query field.

Note

Available only for DQ rule validation.

Guess schema

Click the Guess Schema button to retrieve the schema from the table.

Note

Available only for DQ rule validation.

Query

Enter your DB query paying particular attention to properly sequence the fields in order to match the schema definition.

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.

Note

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

 

Covert 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.

This check box is not visible if Trim all the String/Char columns is selected. Clear 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

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.

Usage

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