tIngresBulkExec properties

tIngresOutputBulk and tIngresBulkExec are generally used together in a two step process. In
the first step, an output file is generated. In the second step, this file is used in
the INSERT operation used to feed a database. These two steps are fused together in the
tIngresOutputBulkExec component, detailed in
another section. The advantage of using two components is that data can be transformed
before it is loaded in the database.

Component family

Databases/Ingres

 

Function

Executes the Insert action on the data provided.

Purpose

Inserts data in bulk to a table in the Ingres DBMS for performance
gain.

Basic settings

Property type

Either Built-in or Repository.

Since version 5.6, both the Built-In mode and the Repository mode are
available in any of the Talend solutions.

 

 

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.

  File name

Name of the file to be loaded.

Warning

This file should be located on the same machine as the
database server.

 

Schema and Edit
Schema

A schema is a row description. It defines the number of fields to be processed and passed on
to the next component. The schema is either Built-In or
stored remotely in the Repository.

Since version 5.6, both the Built-In mode and the Repository mode are
available in any of the Talend solutions.

 

 

Built-In: You create and store the schema locally for this
component only. Related topic: see Talend Studio
User Guide.

 

 

Repository: You have already created the schema and
stored it in the Repository. You can reuse it in various projects and Job designs. Related
topic: see Talend Studio User Guide.

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 details, see https://help.talend.com/display/KB/Verifying+default+values+in+a+retrieved+schema.

   

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.

Advanced settings

Field Separator

Character, string or regular expression to separate fields.

 

Row Separator

String (ex: ”
“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 further information about variables, see Talend Studio
User Guide.

Usage

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

Log4j

The activity of this component can be logged using the log4j feature. For more information on this feature, see Talend Studio User
Guide
.

For more information on the log4j logging levels, see the Apache documentation at http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html.

Limitation

The database server/client must be installed on the same machine
where the 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 your studio. For details, see https://help.talend.com/display/KB/How+to+install+external+modules+in+the+Talend+products
or the section describing how to configure the Studio in the Talend Installation and Upgrade
Guide
.
