示例1: findAndDelete
// Deletes rows in a table of RA result according to some select conditions.
// The RA result is made a copy before using select conditions.
func findAndDelete(t *table.Table, query *ra.Result, conditions ...ra.Condition) int {
_, status := query.Copy().MultipleSelect(conditions...)
if status != st.OK {
return status
}
for _, i := range query.Tables[t.Name].RowNumbers {
status = t.Delete(i)
if status != st.OK {
return status
}
}
return t.Flush()
}示例2: Delete

return status
}
