# 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 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 . ## 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 | | | DQ rule validation | | | 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 click the relevant connection component to
reuse the connection details you already defined.

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 | 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

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:

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.
