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. The schema is either Built-In or stored remotely in the Repository.

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. You can reuse it in various projects and
Job designs. Related topic: see
Talend Studio

User Guide.

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

Type in the exact name of the Stored Procedure

Is Function / Return result
in

Check this box, if a 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 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.

Specify a data source alias

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
. For a related use case, see Scenario: Deploying your Job on Talend Runtime to retrieve data from a MySQL database.

This check box is not available when the Use an existing
connection check box is selected.

Data source alias

Enter the alias of the data source created on the
Talend Runtime
side.

This field is available only when the Specify a data source
alias check box is selected.

Additional JDBC parameters

Specify additional connection properties for the DB connection you
are creating.

tStat
Catcher
Statistics

Select this check box to collect log data at the 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 Scenario: Reading data from databases through context-based dynamic connections and Scenario: 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.
