Rui Wang updated CALCITE-3351:
------------------------------
Description:
Exception was thrown when connecting with mySQL to query Chinese. The following
SQL was executed:
select * from \"test\".\"score_new\" where \"name\"= \'催\' limit 1
，if change "getDefaultCharset" in "RelDataTypeFactoryImpl" to
return Charset.forName("UTF8");
there will be also exception thrown as the following:
java.sql.SQLException: Error while executing SQL "select * from
"test"."score_new" where "name"= '催' limit 1": While executing SQL [SELECT

发现连接mysql进行中文查询时候，执行这条sql：
select * from \"test\".\"score_new\" where \"name\"= \'催\' limit 1报错
，后来修改了RelDataTypeFactoryImpl的
getDefaultCharset方法为
return Charset.forName("UTF8");
还是报错，报错如下：

"test"."score_new" where "name"= '催' limit 1": While executing SQL [SELECT
