Error occurs when the select result key in the SQL query start with a number. This error can occur when searching a Text or a Date field in the widget

The MD5 value of a searched field name can start with a number.

Example: I want to search the end_value field value, it will fail because when the SQL query is built, end_value becomes 9d6a1500cd75d9feb7929f19d5f8cf2b
