tSybaseSCD
Addresses Slowly Changing Dimension needs, reading regularly a source of data and logging the changes into a dedicated SCD table.
tSybaseSCD reflects and tracks changes in a dedicated Sybase SCD table.
tSybaseSCD Standard properties
These properties are used to configure tSybaseSCD running in the Standard Job framework.
The Standard tSybaseSCD component belongs to the Business Intelligence and the Databases families.
The component in this framework is available in all Talend products.
Basic settings
Properties | Description |
---|---|
Database |
Select the desired database type from the list and click Apply. |
Property type |
|
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. Information noteNote: When a Job contains the parent Job and the child Job, do the following if you
want to share an existing connection between the parent Job and the child Job (for example,
to share the connection created by the parent Job with the child Job).
For an example about how to share a database connection across Job levels, see Sharing a database connection. |
DB Version |
Select the version of the Sybase database to be used from the drop-down list. |
Host |
Database server IP address. |
Port |
Listening port number of DB server. |
Database |
Name of the database. |
Username and Password |
DB user authentication data. To enter the password, click the [...] button next to the password field, enter the password in double quotes in the pop-up dialog box, and click OK to save the settings. |
Table |
Name of the table to be written. Note that only one table can be written at a time. |
Schema and Edit schema |
|
SCD Editor |
The SCD editor helps to build and configure the data flow for slowly changing dimension outputs. For more information, see SCD management methodology. |
Use memory saving Mode |
Select this check box to maximize system performance. |
Die on error |
This check box is cleared by default, meaning to skip the row on error and to complete the process for error-free rows. |
Advanced settings
Properties | Description |
---|---|
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. |
End date time details |
Specify the time value of the SCD end date time setting in the format of HH:mm:ss. The default value for this field is 12:00:00. This field appears only when SCD Type 2 is used and Fixed year value is selected for creating the SCD end date. |
tStatCatcher Statistics |
Select this check box to collect log data at the component level. |
Debug mode |
Select this check box to display each step during processing entries in a database. |
Global Variables
Variables | Description |
---|---|
Global Variables |
NB_LINE_UPDATED: the number of rows updated. This is an After variable and it returns an integer. NB_LINE_INSERTED: the number of rows inserted. This is an After variable and it returns an integer. NB_LINE_REJECTED: the number of rows rejected. This is an After variable and it returns an integer. ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box. A Flow variable functions during the execution of a component while an After variable functions after the execution of the component. To fill up a field or expression with a variable, press Ctrl+Space to access the variable list and choose the variable to use from it. For more information about variables, see Using contexts and variables. |
Usage
Usage guidance | Description |
---|---|
Usage rule |
This component is used as Output component. It requires an Input component and Row main link as input. |
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 Dynamic schema and Creating a context group and define context variables in it. |
Limitation |
This component does not support using SCD type 0 together with other SCD types. |
