tIngresBulkExec Standard properties

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.

Table

Name of the table to be filled.

VNode

Name of the virtual node.

Database

Name of the database.

Action on table

Actions that can be taken on the table defined:

None: No operation made to the table.

Truncate: Delete all the rows in the table and release the file space back to the operating system.

Name of the file to be loaded.

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.

When the schema to be reused has default values that are integers or functions, ensure that these default values are not enclosed within quotation marks. If they are, you must remove the quotation marks manually.

For more information, see Retrieving table schemas.

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.

Delete Working Files After Use

Select this check box to delete the files that are created during the execution.

Field Separator

Character, string or regular expression to separate fields.

Row Separator

String (ex: "\n"on Unix) to separate rows

Null Indicator

Value of the null indicator.

Session User

User of the defined session (the connection to the database).

Rollback

Enable or disable rollback.

On Error

Policy of error handling:

Continue: Continue the execution.

Terminate: Terminate the execution.

Reject Row File

Path and name of the file that holds the rejected rows.

Available when Continue is selected from the On Error list.

Error Count

Number of errors to trigger the termination of the execution.

Available when Terminate is selected from the On Error list.

Allocation

Number of pages initially allocated to the table or index.

Extend

Number of pages by which a table or index grows.

Fill Factor

Specify the percentage (from 1 to 100) of each primary data page that must be filled with rows, under ideal conditions. For example, if you specify a fillfactor of 40, the DBMS Server fills 40% of each of the primary data pages in the restructured table with rows.

Min Pages/Max Pages

Specify the minimum/maximum number of primary pages a hash table must have. The Min. pages and Max. pages must be at least 1.

Leaf Fill

A bulk copy from can specify a leaffill value. This clause specifies the percentage (from 1 to 100) of each B-tree leaf page that must be filled with rows during the copy. This clause can be used only on tables with a B-tree storage structure.

Non Leaf Fill

A bulk copy from can specify a nonleaffill value. This clause specifies the percentage (from 1 to 100) of each B-tree non-leaf index page that must be filled with rows during the copy. This clause can be used only on tables with a B-tree storage structure.

Row Estimate

Specify the estimated number of rows to be copied from a file to a table during a bulk copy operation.

Trailing WhiteSpace

Selected by default, this check box is designed to trim the trailing white spaces and applies only to such data types as VARCHAR, NVARCHAR and TEXT.

Encoding

List of the encoding schemes.

Output

Where to output the error message:

to console: Message output to the console.

to global variable: Message output to the global variable.

tStatCatcher Statistics

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

Global Variables 

NB_LINE_DATA: the number of rows read. This is an After variable and it returns an integer.

NB_LINE_BAD: 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 rule

Deployed along with tIngresOutputBulk, tIngresBulkExec feeds the given data in bulk to the Ingres database for performance gain.

The database server/client must be installed on the same machine where Talend Studio is installed or where the Job using tIngresBulkExec is deployed, so that the component functions properly.

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.
