tOracleSP Standard properties

Select a type of database from the list and click Apply.

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.

Property type

Either Built-in or Repository .

Built-in: No property data stored centrally.

Repository: Select the repository file in which the properties are stored. The fields that follow are completed automatically using the data retrieved.

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.

Schema

Name of the 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.

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

SP Name

Type in the exact name of the Stored Procedure (or Function)

Is Function / Return result in

Select this check box, if the stored procedure is a function and one value only is to be returned.

Select on the list the schema column, the value to be returned is based on.

Parameters

Click the Plus button and select the various Schema Columns that will be required by the procedures. Note that the SP schema can hold more columns than there are parameters used in the procedure.

Select the Type of parameter:

IN: Input parameter.

OUT: Output parameter/return value.

IN OUT: Input parameter is to be returned as value, likely after modification through the procedure (function).

RECORDSET: Input parameters is to be returned as a set of values, rather than single value.

The Custom Type is used when a Schema Column you want to use is user-defined. Two Custom Type columns are available in the Parameters table. In the first Custom Type column:

- Select the check box in the Custom Type column when the corresponding Schema Column you want to use is of user-defined type.

- If all listed Schema Columns in the Parameters table are of custom type, you can select the check box before Custom Type once for them all.

Select a database type from the DB Type list to map the source database type to the target database type:

- Auto-Mapping: Map the source database type to the target database type automatically.(default)

- CLOB: Character large object.

- BLOB: Binary large object.

- DECIMAL: Decimal numeric object.

- NUMERIC: Character 0 to 9.

- XMLTYPE: XML schema type.

In the second Custom Type column, you can precise what the custom type is. The type may be:

- STRUCT: used for one element.

- ARRAY: used for a collection of elements.

In the Custom name column, specify the name of the custom type that you have given to this type.

Select this check box 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 .

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.

NLS Language

In the list, select the language used for the data that are not used in Unicode.

NLS Territory

Select the conventions used for date and time formats. The default value is that of the operating system.

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at a Job level as well as at each component level.

Usage rule

This component is used as intermediary component. It can be used as start component but only input parameters are thus allowed.

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.

Limitation

The Stored Procedures syntax should match the Database syntax.

When the parameters set in this component are of Custom Type, the tJava family components should be placed before the component in order for users to define values for the custom-type parameters, or after the component so as to read and output the Out-type custom parameters.
