tSAPHanaRow Standard properties

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

The Standard tSAPHanaRow component belongs to the Databases family.

The component in this framework is available in all Talend products with Big Data and in Talend Data Fabric.

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. Information noteNote: 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 database server.
Username and Password	Database 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: The schema is created and stored locally for this component only. For more information, see Talend Studio User Guide.
	Repository: The schema already exists and is stored in the Repository, hence can be reused. For more information, 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.
Table Name	Name of the table to be written. Note that only one table can be written at a time.
Query Type	Either Built-in or Repository.
	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.
Guess Query	Click the Guess Query button to generate the query which corresponds to your table schema in the Query field.
Query	Enter your database query paying particularly attention to properly sequence the fields in order to match the schema definition.
Die on error	This check box is cleared by default. This means that Die on error skips the row when an error is encountered and completes the process for rows without errors.

Advanced settings

Additional JDBC Parameters	Specify additional connection properties in the database connection you are creating. This option is not available if you have selected Use an existing connection check box in the Basic settings.
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. Information noteNote: This option allows the component to have a different schema from that of the preceding component. Moreover, the column that holds the QUERY's recordset should be set to the type of Object and this component is usually followed by tParseRecordSet.
Commit every	Number of rows to be completed before committing batches of rows together into the database. This option ensures transaction quality (but not rollback) and above all better performance on executions.
Use PreparedStatement	Select this check box if you want to query the database using a PreparedStatement. In the Set PreparedStatement Parameter table, define the parameters represented by "?" in the SQL instruction of the Query field in the Basic Settings tab. Parameter Index: Enter the parameter position in the SQL instruction. Parameter Type: Enter the parameter type. Parameter Value: Enter the parameter value. Information noteNote: This option is very useful if you need to execute the same query several times. Performance levels are increased.
tStatCatcher Statistics	Select this check box to collect log data at the component level.

Global Variables

Global Variables	QUERY: the query statement being processed. This is a Flow variable and it returns a string. 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 further information about variables, see Talend Studio User Guide.

Usage

Usage rule	This component offers the flexibility of the database query and covers all possible SQL queries.
Support	tSAPHanaRow should be used to interact with the ERP part of SAP, including S4/HANA.
