在这种情况下＆＃34;其中＆＃34;子句在memsql中不起作用

Question

我已经成功地将数据从MySQL加载到MemSQL v6.0-beta中

CREATE TABLE ashareeodprices (
 OBJECT_ID  varchar(38),
 S_INFO_WINDCODE    varchar(40),
 TRADE_DT   varchar(8),
 CRNCY_CODE varchar(10),
 S_DQ_PRECLOSE  double,
 S_DQ_OPEN  double,
 S_DQ_HIGH  double,
 S_DQ_LOW   double,
 S_DQ_CLOSE double,
 S_DQ_CHANGE    double,
 S_DQ_PCTCHANGE double,
 S_DQ_VOLUME    double,
 S_DQ_AMOUNT    double,
 S_DQ_ADJPRECLOSE   double,
 S_DQ_ADJOPEN   double,
 S_DQ_ADJHIGH   double,
 S_DQ_ADJLOW    double,
 S_DQ_ADJCLOSE  double,
 S_DQ_ADJFACTOR double,
 S_DQ_AVGPRICE  double,
 S_DQ_TRADESTATUS   varchar(10),
 OPDATE datetime,
 OPMODE varchar(1)
)

和

LOAD DATA INFILE '/ashareeodprices.csv' INTO TABLE ashareeodprices
FIELDS TERMINATED BY ';'
LINES TERMINATED BY '\n'

然后

SELECT * FROM ashareeodprices;
SELECT * FROM ashareeodprices WHERE S_DQ_LOW=0;

这些SQL语句在MySQL和MemSQL中都可以正常工作。但在这种情况下它没有。

SELECT * FROM ashareeodprices WHERE S_INFO_WINDCODE='600031.SH';

在MySQL中可行。在MemSQL中它返回

Empty set

我认为问题在于编码。有什么问题＆＃39; 600031.SH＆＃39;？
