> Key: HIVE-8824
> URL: https://issues.apache.org/jira/browse/HIVE-8824
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 0.13.1
> Reporter: lixuebin
>
> Hive Metstore Database is MySQL.
> First:
> set hive-site.xml hive.metastore.try.direct.sql true
> second:
> On impala
> show table stats xxxxx;
> Remark:
> MYSQL does not support table name and column name with double quotes, such as
> : select * from "testtb" where "id"='1234';
> should be: select * from testtb where id='1234';
> MetaStoreDirectSql.java should be checked.
> The Exception:
> metastore.ObjectStore (ObjectStore.java:handleDirectSqlError(2243)) - Direct
> SQL failed, falling back to ORM
> javax.jdo.JDODataStoreException: Error executing SQL query "select
> "COLUMN_NAME", "COLUMN_TYPE", "LONG_LOW_VALUE", "LONG_HIGH_VALUE",
> "DOUBLE_LOW_VALUE", "DOUBLE_HIGH_VALUE", "BIG_DECIMAL_LOW_VALUE",
> "BIG_DECIMAL_HIGH_VALUE", "NUM_NULLS", "NUM_DISTINCTS", "AVG_COL_LEN",
> "MAX_COL_LEN", "NUM_TRUES", "NUM_FALSES", "LAST_ANALYZED" from
> "TAB_COL_STATS" where "DB_NAME" = ? and "TABLE_NAME" = ? and "COLUMN_NAME"
> in (?)".
