+
+## 2026-08-07 实测补充：全 @ 场景强制 new OpenSQL 语法（新坑）
+
+**症状**：已修复 @ 一致性（INTO 目标补 @）后，又报新错误：
+```
+If host variables are escaped using @, new OpenSQL must used
+```
+
+**根因**：@ 转义属于"新 OpenSQL"语法体系。一旦语句用了 @，整条语句必须完全遵循新 OpenSQL 语法规则：
+- **字段列表必须逗号分隔**（旧式空格分隔报错）：`SELECT carrid, connid, fldate FROM sflight`
+- **INTO 子句前置**（在 FROM/WHERE 之前）：`SELECT f1, f2 FROM tab INTO TABLE @lt_data WHERE ...`
+- 旧式写法 `SELECT carrid connid fldate FROM sflight INTO TABLE lt_data`（无逗号）在全 @ 场景下报错
+
+**验证示例（ZBC400_REVIEW_DEMO 2026-08-07 实测，syntax-check 全绿）**：
+```abap
+" ✅ 正确 — 新 OpenSQL 全 @：字段逗号分隔 + INTO 前置 + 全部 @
+SELECT carrid, connid, fldate, seatsmax, seatsocc
+  FROM sflight
+  INTO TABLE @gt_result
+  WHERE carrid IN @s_carrid
+    AND fldate IN @s_date.
+
+" ❌ 同语句 INTO 不带 @：When escaped, all host variables must be escaped using @
+" ❌ 字段无逗号（旧式空格分隔）：If host variables are escaped using @, new OpenSQL must used
+```
+
+**经验**：评审/优化代码时，只要目标系统是 7.40 SP05+ 且采用 @ 风格，直接按新 OpenSQL 规范写（字段逗号分隔 + INTO 前置 + 全 @），一次通过。质检判断"INTO TABLE 目标是豁免位置"**不成立**（2026-08-07 实测推翻），@ 必须全局一致。
