To update all the records in a table, specify the table name, and then use the SET clause to specify the field or fields to be changed. In most cases, you will want to qualify the UPDATE statement with a WHERE clause to limit the number of records changed.
Inner Peace is an expression that refers to a state of being mentally or spiritually at peace, with enough knowledge and understanding to keep oneself strong in the face of discord or stress.
My research tells me that currently there is no universally recognized symbol for inner peace. I believe that people of all cultures and countries long for inner peace, and yet at this point in time there is no globally recognized symbol for inner peace around which the global family can rally.
