flink SQL 运行 String sqlWindPrice = "create VIEW temp_wind_price as " + "select SUBSTRING（s_info_windcode,1,6) as ts_code," + "s_dq_close as close_price " + "from AShareEODPrices " + "where trade_dt = '20010823'"; tEnv.executeSql(sqlWindPrice); 报错Encountered: "\uff08" (65288), after : ""

在你提供的代码中，报错是由于使用了错误的括号符号导致的。请注意，正确的括号符号应该是半角括号 "(" 和 ")"，而不是全角括号 "（" 和 "）"。请尝试将代码中的全角括号替换为半角括号，如下所示：

String sqlWindPrice = "CREATE VIEW temp_wind_price AS " +
    "SELECT SUBSTRING(s_info_windcode, 1, 6) AS ts_code, " +
    "s_dq_close AS close_price " +
    "FROM AShareEODPrices " +
    "WHERE trade_dt = '20010823'";
tEnv.executeSql(sqlWindPrice);

请确保在代码中使用半角括号来定义字符串，以避免类似的语法错误。
