Java SQLDataException: Cannot Determine Value Type from String '1-7'

This error message indicates that there's a problem determining the data type of a value being read from a database. Specifically, the value '1-7' is read as a string, but its intended data type is unclear.

This error commonly occurs when using a JDBC driver to read data. The driver needs to understand the data type of each database column to correctly convert the internal representation into a Java object.

To resolve this, examine the code reading database data and ensure all column data types are accurately specified. In some cases, adjusting the database schema to use the correct data types might be necessary.
