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

The Standard tHSQLDbRow component belongs to the Databases family.

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

Basic settings

Property type

Either Built-in or Repository .

Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions.

 

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.

Running Mode

Select on the list the Server Mode corresponding to your DB setup among the four propositions :

HSQLDb Server, HSQLDb WebServer, HSQLDb In Process Persistent, HSQLDb In Memory.

Use TLS/SSL sockets

Select this check box to enable the secured mode if required.

Host

Database server IP address

Port

Listening port number of DB server.

Database Alias

Name of the database

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.

DB path

Specify the directory to the database you want to connect to. This field is available only to the HSQLDb In Process Persistent running mode.

Note:

By default, if the database you specify in this field does not exist, it will be created automatically. If you want to change this default setting, modify the connection parameter set in the Additional JDBC parameter field in the Advanced settings view

Database

Enter the database name that you want to connect to. This field is available only to the HSQLDb In Process Persistent running mode and the HSQLDb In Memory running mode.

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.

Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions.

 

Built-in: The schema is created and stored locally for this component only. Related topic: see Talend Studio User Guide.

 

Repository: The schema already exists and is stored in the Repository, hence can be reused. 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.

Query type

Either Built-in or Repository .

Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions.

 

Built-in: Fill in manually the query statement or build it graphically using SQLBuilder

 

Repository: Select the relevant query stored in the Repository. The Query field gets accordingly filled in.

Query

Enter your DB query paying particularly attention to properly sequence the fields in order to match the schema definition.

Die on error

This check box is selected by default. Clear the check box to skip the row on error and complete the process for error-free rows. If needed, you can retrieve the rows on error via a Row > Rejects link.

Advanced settings

Additional JDBC parameters

Specify additional connection properties for the DB connection you are creating. When the running mode is HSQLDb In Process Persistent , you can set the connection property ifexists=true to allow connection to an existing database only and avoid creating a new database.

Propagate QUERY's recordset

Select this check box to insert the result of the query into a COLUMN of the current flow. Select this column from the use column list.

Commit every

Number of rows to be completed before committing batches of rows together into the DB. This option ensures transaction quality (but not rollback) and above all better performance on executions.

tStat Catcher Statistics

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

Global Variables

Global Variables

QUERY: Indicates the query to be processed. This is a Flow variable and it returns a string.

For further information about variables, see Talend Studio User Guide.

Note:

A Flow variable means it functions during the execution of a component while an After variable means it functions after the execution of a component.

Usage

Usage rule

This component offers the flexibility of the DB query and covers all possible SQL queries.

Connections

Outgoing links (from this component to another):

Row: Main; Reject; Iterate

Trigger: Run if; On Component Ok; On Component Error; On Subjob Ok; On Subjob Error.

Incoming links (from one component to this one):

Row: Main; Iterate

Trigger: Run if; On Component Ok; On Component Error; On Subjob Ok; On Subjob Error.

For further information regarding connections, see Talend Studio User Guide.

Limitation

Due to license incompatibility, one or more JARs required to use this component are not provided. You can install the missing JARs for this particular component by clicking the Install button on the Component tab view. You can also find out and add all missing JARs easily on the Modules tab in the Integration perspective of your studio. For details, see Installing external modules.
