# tPostgresqlInvalidRows Standard properties These properties are used to configure tPostgresqlInvalidRows running in the Standard Job framework. The Standard tPostgresqlInvalidRows 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: 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 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:

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.
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*. | | DB Version | List of database versions. | | Host | Database server IP address. | | Port | Listening port number of DB server. | | Database | Name of the database. | | Postgresql schema | Name of the Postgresql 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.

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 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 JDBC parameters for the
database connection created.

This property is not available when the Use an existing connection
check box in the Basic settings view is selected. | | --- | --- | | Use cursor | Select this check box to specify the number of rows you want to
work with 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. | | tStatCatcher Statistics | Select this check box to collect log data at the 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*. | | --- | --- | ## Usage | **Usage rule** | This component can be used as a start or intermediary step. It
requires an output flow. | | --- | --- | | Dynamic settings | Click the [+] button to add a row in the table
and fill the Code field with a context
variable to choose your database connection dynamically from multiple
connections planned in your Job. This feature is useful when you need to
access database tables having the same data structure but in different
databases, especially when you are working in an environment where you
cannot change your Job settings, for example, when your Job has to be
deployed and executed independent of Talend Studio.

The Dynamic settings table is
available only when the Use an existing
connection check box is selected in the Basic settings view. Once a dynamic parameter is
defined, the Component List box in the
Basic settings view becomes unusable.

For examples on using dynamic parameters, see and . For more information on Dynamic
settings and context variables, see Talend Studio
User Guide. |
