tDB2SP Standard properties

These properties are used to configure tDB2SP running in the Standard Job framework.

The Standard tDB2SP 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.
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. 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: 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. 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.
Property type	Either Built-in or Repository .
	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.
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, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.
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	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. 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.
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 . 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.

Advanced settings

Additional JDBC parameters	Specify additional connection properties for the DB connection you are creating. Note: You can set the encoding parameters through this field.
tStat Catcher Statistics	Select this check box to collect log data at the component level.

Usage

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 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.
