tInformixSP – Docs for ESB 7.x

tInformixSP

Centralises and calls multiple and complex queries in a database.

tInformixSP calls procedures stored in a database.

tInformixSP Standard properties

These properties are used to configure tInformixSP running in the Standard Job framework.

The Standard
tInformixSP component belongs to the Databases family.

The component in this framework is available in all Talend
products
.

Note: 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 Dynamic database components.

Basic settings

Database

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

Property type

Either Built-in or
Repository
.

 

Built-in: No properties stored
centrally.

 

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

Use an existing connection

Select this check box and in the Component List click the relevant connection component to
reuse the connection details you already defined.

Note: When a Job contains the parent Job and the child Job, if you
need to share an existing connection between the two levels, for example, to share the
connection created by the parent Job with the child Job, you have to:

  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

Talend Studio
User Guide
.

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

User authentication information.

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.

Instance

Name of the Informix instance to be used. This information can
generally be found in the SQL hosts
file.

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.

Note:

Check Inserting data in mother/daughter tables, if you want to analyze a set
of records from a database table or DB query and return single
records.

Use Transaction

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

Advanced settings

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

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.
