+# REPEAT
+
+交易过程 trade 中有一个遍历交易项的循环，当累计的总交易额 `@total_price` 超过 20000， 这个循环就结束
+
+```mysql
+-- ...
+trade: LOOP
+    -- ... 
+    if @total_price > 20000 then
+        LEAVE trade;
+    else
+        ITERATE trade;
+    end if;
+    -- ...
+end LOOP trace;
+```
+
+现在 Joe 想要用 `REPEATE` 简化这个 `LOOP` 循环，他应该怎么做？
+
+## 答案
+
+```mysql
+trade: REPEATE
+    -- 省略交易过程
+    UNTIL @total_price > 20000
+END REPATE trade;
+```
+
+## 选项
+
+### A
+
+```mysql
+trade: REPEATE
+    UNTIL @total_price > 20000
+    -- 省略交易过程
+END REPATE trade;
+```
+
+### B
+
+```mysql
+REPEATE @total_price > 20000
+    -- 省略交易过程
+END REPATE;
+```

+### C
+
+```mysql
+trade: REPEATE
+    -- 省略交易过程
+    IF @total_price > 20000

+

+
