Checking and customizing the file schema

About this task

The last step shows the Delimited File schema generated. You can customize the schema using the toolbar underneath the table.

If the Delimited file which the schema is based on has been changed, use the Guess button to generate again the schema. Note that if you customized the schema, the Guess feature does not retain these changes.
Modify the schemas if needed.

Information noteWarning: Avoid using any Java reserved keyword as a schema column name.

Make sure the data type in the Type column is correctly defined.

For more information regarding Java data types, including date pattern, see Java API Specification.
Below are the commonly used Talend data types:
- Object: a generic Talend data type that allows processing data without regard to its content, for example, a data file not otherwise supported can be processed with a tFileInputRaw component by specifying that it has a data type of Object.
- List: a space-separated list of primitive type elements in an XML Schema definition, defined using the xsd:list element.
- Dynamic: a data type that can be set for a single column at the end of a schema to allow processing fields as VARCHAR(100) columns named either as ‘Column<X>’ or, if the input includes a header, from the column names appearing in the header. For more information, see Dynamic schema.
- Document: a data type that allows processing an entire XML document without regarding to its content.
Click Finish. The new schema is displayed under the relevant File Delimited connection node in the Repository tree view.
