Schema and Edit Schema

A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. When you create a Spark Job, avoid the reserved word line when naming the fields.

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.

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.

SP Name

Enter the exact name of the stored procedure (SP).

Is Function / Return result in

Select this check box if only one value must be returned.

From the list, select the the schema column upon which the value to be obtained is based.

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 parameters 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.

Use Transaction

Clear this check box if the database is configured in the NO_LOG mode.

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.

tStatCatcher Statistics

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

Usage rule

This is an intermediary component. It can also be used as an entry component. In this case, only the entry parameters are authorized.

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 procedure syntax must correspond to that of the database.

This component requires installation of its related jar files.
