1. When adding data to SQL, you must have the condition that the Insert field is in the table in the (Select) field.

INSERT INTO table_name (V1,V2,V3) VALUES (select a,b,c from query table where condition)

2. This SQL can replicate data

Insert INTO Inj_wash_updatelog g (g.proid,g.update_date)
Select T.proid,t.subdate from Inj_wash_pro t
where T.proid not in (select G.proid from Inj_wash_updatelog g)

New SQL can be followed by a Where condition (multiple tables associated with new and replicated data)
