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

The Standard tJDBCColumnList component belongs to the Databases family.

The component in this framework is available in all Talend products.

Basic settings

Database Type

Select the type of the database to be accessed.

Component list

Select the tJDBCConnection component in the list if more than one connection are planned for the current Job.

Table name

Enter the name of the table.

Die on error

Select this check box to stop the execution of the Job when an error occurs.

Clear the check box to skip any rows on error and complete the process for error-free rows. When errors are skipped, you can collect the rows on error using a Row > Reject link.

Global Variables

Global Variables

CURRENT_COLUMN: the name of the column currently iterated upon. This is a Flow variable and it returns a string.

CURRENT_COLUMN_TYPE: the ID of the type of the column currently iterated upon. This is a Flow variable and it returns an integer.

CURRENT_COLUMN_TYPE_NAME: the name of the type of the column currently iterated upon. This is a Flow variable and it returns a string.

CURRENT_COLUMN_PRECISION: the precision of the column currently iterated upon. This is a Flow variable, and it returns an integer.

CURRENT_COLUMN_SCALE: the scale of the column currently iterated upon. This is a Flow variable, and it returns an integer.

NB_COLUMN: the number of columns iterated upon so far. 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.
