我在我的 spring 配置中得到了这个 sql 属性：
<property name="LAUSFT">
<value>
SET @vfrom = ?;
SET @vto = ?;
SELECT * FROM (
SELECT s.*, @rank
:= @rank + 1 rank
FROM quiz.score s, (SELECT @rank := 0) init
ORDER BY points DESC
) s
WHERE rank BETWEEN @vfrom AND @vto
ORDER BY rank;
</value>
</property>
如果我在 MySQL 工作台中执行它，则 sql 运行没有问题。在我的道课上也是正确的。但是，如果我在我的 dao 类中执行 sql，我每次都会遇到这个错误：
org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [
SET @vfrom := ?;
SET @vto := ?;
SELECT * FROM (
SELECT s.*, @rank := @rank + 1 rank
FROM quiz.score s, (SELECT @rank := 0) init
ORDER BY points DESC
) s
WHERE rank BETWEEN @vfrom AND @vto
ORDER BY rank;
]; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET @vto := 1;
SELECT * FROM (
SELECT s.*, @rank := @rank + 1 rank

我很伤心。一切正常如果我在工作台中运行 sql 那么问题出在哪里？
这里是java函数：
public List<Score> loadAllScore(int pFrom, int pTo) {
return createJdbcTemplate()
.query(mLAUSFT,
new Object[] { pFrom, pTo }, mScoreMapper);
}
谢谢你的帮助。
