1. 点击侧边栏表名插入 db.table 格式(如 log_analytics.access_logs)
   - SchemaSidebar 表名: onInsert(t.name) → onInsert(`${dbName}.${t.name}`)
   - SchemaSidebar 字段名: onInsert(col.Field) → onInsert(`${t.name}.${col.Field}`)
2. 查询不存在的表应显示错误而非'无结果数据'
   - QueriesPage handleExecute: 检查 res.error 字段,有错误则 setError + 不设 result
