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. The schema is either Built-In or stored remotely in the Repository.
-
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.
Click Edit schema to make changes to the
schema. Note that if you make changes, the schema automatically becomes built-in.
-
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.
This component offers the
advantage of the dynamic schema feature. This allows you to retrieve unknown columns
from source files or to copy batches of columns from a source without mapping each
column individually. For further information about dynamic schemas, see
Talend Studio
User Guide.
This dynamic schema
feature is designed for the purpose of retrieving unknown columns of a table and is
recommended to be used for this purpose only; it is not recommended for the use of
creating tables.
|
|
Name
|
Enter the name of the Data Store Object from which data will be retrieved.
|
|
Max row number
|
Specify the maximum number of rows to be retrieved. By default,
the value is set to -1, which means all rows will be
retrieved.
|
|
Filter Group
|
Specify the search condition(s) used to filter
data to be retrieved by clicking the [+] button to
add as many rows as needed, each row for a search condition, and set the
value of the following attributes for each condition.
-
Column: enter the name of the schema column
based on which retrieved data will be filtered.
-
Sign: select either
Include or Exclude
from the drop-down list.
-
Operator: select from the drop-down list the
data filter operator used to build the search condition.
-
Value: specify the search value used to build
the search condition.
-
High value: specify another search value used
to build the search condition for the between operator.
When using a column of Date type to specify a filter, the date and
time values in the Value and High
Value columns should be in the format
yyyyMMdd and
HHMMSS, which might be different from the
format defined in the schema editor.
The following wildcard characters can
be used when specifying the search value using pattern:
-
*: match any number of characters.
-
+: match a single character.
-
#: be used to escape characters (e.g. *, #)
and for exact case sensitive comparison.

|
Specify a shared destination
|
Select this check box and specify the shared destination in the
Shared destination name field
displayed. The shared destination allows the SAP components to use the
shared destination on the Talend Runtime when they are executed as part of
an ESB Route or ESB Data Service within the Talend Runtime
container OSGi Environment.
Besides specifying the shared destination name in the component,
you also need to setup the SAP DataSource for the Talend Runtime.
What you need to do to define the SAP DataSource and how to configure it are
described in the readme.txt provided in the Talend ESB
package within the /add-ons/datasource/sap folder.
Note that if you use the component’s own connection configuration,
your SAP connection will be closed at the end of the component. To prevent
this from happening, use a shared destination with its name specified.
|
|
Use FTP-Batch Options
|
Select this check box when the size of data to be retrieved is larger than
the size specified in the Fetch size field. With this
check box selected, the SAP system will generate as many files as needed and
write the retrieved data into these files, and this component will then read
the files via an FTP connection to retrieve data and transfer the retrieved
data to the output component.
The following properties need to be specified when this check box is
selected:
-
Host: The IP address or host name of the FTP
server.
-
Port: The listening port number of the FTP
server.
-
User and Password: The
user authentication data required to access the FTP server.
-
Directory: The directory where the files
generated by the SAP system will be saved.
-
Data filename prefix: The prefix of the files
generated by the SAP system.
