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.

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.

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

Oracle SID: Select this connection type to uniquely identify a particular database on a system.

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

DB Version

Select the Oracle version in use.

Host

IP address of the database server.

Port

Port number listening the database server.

Database

Database name.

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.

Table

Name of the table to be written. Note that only one table can be written at a time.

Action on table

On the table defined, you can perform one of the following operations:

None: No operation is carried out.

Drop and create table: The table is removed and created again.

Create table: The table does not exist and gets created.

Create table if not exists: The table is created if it does not exist.

Drop table if exists and create: The table is removed if it already exists and created again.

Clear table: The table content is deleted.

Truncate table: The table content is deleted. You do not have the possibility to rollback the operation.

Data file name

Name of the file to be loaded.

Action on data

On the data of the table defined, you can perform:

Insert: Insert data to an empty table. If the table already contains data, the Job stops and the existing data remains in the table.

Update: Update the existing data. You have to set the key on the schema if this option is selected.

Append: Append data to the table, whether the table is empty or not.

Replace: if the table already contains data, delete all the existing data and insert the new data. If the table is empty, insert the new data.

Truncate: If the table already contains data, truncate all the existing data and insert the new data. If the table is empty, insert the new data.

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.

Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs.

When the schema to be reused has default values that are integers or functions, ensure that these default values are not enclosed within quotation marks. If they are, you must remove the quotation marks manually.

For more information, see the related description of retrieving table schemas in Talend Studio User Guide.

Advanced separator (for number)

Select this check box to change the separator used for the numbers.

Character, string or regular expression to separate fields:

None: no separator is used.

Whitespace: the separator used is a space.

EOF (used for loading LOBs from lobfile): the separator used is an EOF character (End Of File).

Other terminator: Set another terminator in the Field terminator field.

Use fields enclosure

Select this check box if you want to use enclosing characters for the text:

Fields enclosure (left part): character delimiting the left of the field.

Field enclosure (right part): character delimiting the right of the field.

Use schema's Date Pattern to load Date field

Select this check box to use the date pattern of the schema in the date field.

Specify field condition

Select this check box to define data loading condition.

Preserve blanks

Select this check box to preserve the blanks.

Trailing null columns

Select this check box to load null columns.

Select this check box to modify the territory conventions used for day and weeks numbering. Your OS value is the default value used.

Encoding

Select the encoding from the list, or enter the encoding between double quotes if it does not exist in the list. This field is compulsory for database data handling.

Output

Select the type of output for the standard output of the Oracle database:

to console,

to global variable.

Convert columns and table names to uppercase

Select this check box to uppercase the names of the columns and the name of the table.

tStatCatcher Statistics

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

Global Variables

NB_LINE_DATA: the number of rows read. This is an After variable and it returns an integer.

NB_LINE_BAD: the number of rows rejected. This is an After variable and it returns an integer.

NB_LINE_INSERTED: the number of rows inserted. This is an After variable and it returns an integer.

RETURN_CODE: the return code indicating the result of processing. This is an After variable and it returns an integer.

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 rule

This dedicated component offers performance and flexibility of Oracle DB query handling.

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 and Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic settings and context variables, see Talend Studio User Guide.
