tIngresRow Standard properties - Cloud

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

The Standard tIngresRow 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 DB Generic components.

Basic settings

Database	Select the desired database type from the list and click Apply.
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.
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, 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). 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 Sharing a database connection.
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.
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.
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.
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 JDBC parameters for the database connection created. This property is not available when the Use an existing connection check box in the Basic settings view is selected.
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.
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. Note: This option is very useful if you need to execute the same query several times. Performance levels are increased
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: 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

Usage rule	This component offers the flexibility of the DB query and covers all possible SQL queries.
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 Talend Studio. For details, see Installing external modules.
