tELTMysqlInput – Docs for ESB 7.x


Adds as many Input tables as required for the most complicated Insert

The three ELT Mysql components are closely related, in
terms of their operating conditions. These components should be used to handle Mysql DB
schemas to generate Insert statements, including clauses, which are to be executed in
the DB output table defined.

tELTMysqlInput provides the table schema to be used for
the SQL statement to execute.

tELTMysqlInput Standard properties

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

The Standard
tELTMysqlInput component belongs to the ELT family.

The component in this framework is available in all Talend

Basic settings

Schema and Edit

A schema is a row description, it defines the nature and number of
fields to be processed. The schema is either built-in or remotely stored
in the Repository. The Schema defined is then passed on to the ELT
Mapper to be included to the Insert SQL statement.

Click Edit
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


Built-in: The schema is created and
stored locally for this component only. Related topic: see
Talend Studio User Guide


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

Global Variables

Global Variables

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 +
to access the variable list and choose the variable to use from it.

For further information about variables, see
Talend Studio

User Guide.


Usage rule

tELTMysqlInput is to be used along
with the tELTMysqlMap. Note that the
Output link to be used with these components must correspond strictly to
the syntax of the table name.


Note that the ELT components do not handle actual data flow but
only schema information.
