Octoparse supports exporting data to your MySQL SQL Server, Oracle, or PostgreSQL databases directly, which makes exporting data quite convenient. However, you might encounter different errors when connecting to your database or exporting data.

In this tutorial, we will explain how to fix some frequently encountered errors when exporting to your databases.

This error occurs when the database field column length is too short for one data line.

Solution: Please try to set the data field type to text/longtext, or set the field length as maximum.

This error happens when there are special characters in your data lines but the database field type does not support the special characters.

Solution: You can try to change the encoding to "utf8mb4" and set the field type to text/varchar.

This error happens when you set up one field to be "Not Null" but in the data, this field does not always have a value.

Solution: You can either set up a default value for the field when it is blank or cancel the "Not Null" setting.

This error occurs when your target database client version is not supported.

Solution: Please download MySQL version 5.6 to do the exporting.

This can occur in various situations. Please ensure your task contains non-exported data before using the auto-export feature, as it only exports non-exported data.

Solution: You can first test the manual export to see if any error messages appear, which might help us locate the issue.
