This is the key part of the error and why that particular script invocation didn’t work (violation of a primary key constraint):
Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Violation of PRIMARY KEY constraint 'PK_tblTiempos'. Cannot insert duplicate key in object 'dbo.tblTiempos'. The duplicate key value is (1, 1, 1, Dec 16 2020 4:27PM).
