# tOracleInput Standard properties These properties are used to configure tOracleInput running in the Standard Job framework. The Standard tOracleInput component belongs to the Databases family. The component in this framework is available in all Talend products. 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](https://help.qlik.com/talend/r/en-US/8.0/components/db-generic/db-generic-component). ## Basic settings | Properties | Description | | --- | --- | | Database | Select the desired database type from the list and click
Apply. | | Property type | Either Built-In or Repository.


Built-In: No property data stored centrally.


Repository: Select the repository file where the
properties are stored. | | ![](https://help.qlik.com/talend/en-US/components/8.0/Resources/images/Save_Icon.png) | Click this icon to open a database connection wizard and
store the database connection parameters you set in the component
Basic settings view.

For more information about setting up and storing
database connection parameters, see [Centralizing database metadata](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/centralizing-database-metadata). | | 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.

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](https://help.qlik.com/talend/r/en-US/7.3/studio-user-guide/sharing-database-connection). | | Connection type | Drop-down list of available drivers:


Oracle OCI: Select this
connection type to use Oracle Call Interface with a set of C-language
software APIs that provide an interface to the Oracle database.


Oracle Custom: Select this
connection type to access a clustered database.


Oracle Service Name: Select this
connection type to use the TNS alias that you give when you connect to
the remote database.


WALLET: Select this connection
type to store credentials in an Oracle wallet.


Oracle SID: Select this
connection type to uniquely identify a particular database on a
system. | | DB Version | Select the Oracle version in use. | | Host | Database server IP address. | | Port | Listening port number of DB server. | | Database | Name of the database. | | Oracle schema | Oracle schema name. | | 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 | | | Table name | Database table name. | | Query type and Query | Enter your DB query paying particularly attention to
properly sequence the fields in order to match the schema definition.

If
using the dynamic schema feature, the SELECT query must include the
\* wildcard, to retrieve all
of the columns from the table selected. | | Specify a data source alias | Select this checkbox and specify the alias of a data source created on the *Talend Runtime* side to use the shared connection pool defined in the data source configuration. This
option works only when you deploy and run your Job in *Talend Runtime*.

If you use the component's own DB configuration, your data source
connection will be closed at the end of the component. To prevent this from
happening, use a shared DB connection with the data source alias specified.

This checkbox is not available when the Use an existing
connection checkbox is selected. | ## Advanced settings | Properties | Description | | --- | --- | | Additional JDBC parameters | Specify additional connection properties for the database connection you are
creating. The properties are separated by semicolon and each property is a key-value
pair, for example, *encryption=1;clientname=Talend*.

This field is not available if the Use an existing
connection check box is selected. | | 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 fetch size | Select this check box and in the
Fetch size
field displayed, specify the number of rows to fetch in one go from the
database. The performance can be improved by tuning this fetch size to
an appropriate value. | | 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 defined
columns. | | No null values | Check this box to improve the performance if there are no
null values. | | Support NLS | Select this option to enable globalization support. See [Overview of Globalization Support](https://docs.oracle.com/en/database/oracle/oracle-database/21/nlspg/overview-of-globalization-support.html) for
related information.

This option is available when the Use an existing
connection option is cleared and Oracle 18 and
above is selected from the DB Version
drop-down list in the Basic settings view.

Information noteNote: This option is available only when you have installed the 8.0.1-R2022-09
Talend Studio
Monthly update or a later one delivered by Talend. For more information, check with your administrator. | ## Global Variables | Variables | Description | | --- | --- | | Global Variables | NB\_LINE:
the number of rows processed. 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 checkbox is
cleared, if the component has this checkbox.

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](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/contexts-and-variables). | ## Usage | Usage guidance | Description | | --- | --- | | **Usage rule** | This component covers all possible SQL queries for Oracle
databases. | | 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 [Reading data from databases through
context-based dynamic connections](https://help.qlik.com/talend/r/en-US/8.0/components/defining-context-groups/reading-data-from-databases-through-context-based-dynamic-connections) and [Reading data from different MySQL databases
using dynamically loaded connection parameters](https://help.qlik.com/talend/r/en-US/8.0/components/context/reading-data-from-different-mysql-databases-using-dynamically-loaded-connection-parameters). For more information on
Dynamic settings and context variables, see
[Dynamic schema](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/dynamic-schema) and [Creating a context group and define context
variables in it](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/creating-context-group-and-define-context-variables-in-it). | | Limitation | Due to license incompatibility, one or more JARs required to use this component
