tSAPHanaRow Standard properties

Select the desired database type 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.

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, enter the password in double quotes in the pop-up dialog box, 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.

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

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.

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.

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.

tStatCatcher Statistics

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

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 more information about variables, see Using contexts and variables.

Usage rule

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