1 year ago SELECT TABLE_SCHEMA AS TABLE_CAT, NULL AS TABLE_SCHEM, TABLE_NAME, CASE WHEN TABLE_TYPE='BASE TABLE' THEN CASE WHEN TABLE_SCHEMA = 'mysql' OR TABLE_SCHEMA = 'performance_schema' THEN 'SYSTEM TABLE' ELSE 'TABLE' END WHEN TABLE_TYPE='TEMPORARY' THEN 'LOCAL_TEMPORARY' ELSE TABLE_TYPE END AS TABLE_TYPE, TABLE_COMMENT AS REMARKS, NULL AS TYPE_CAT, NULL AS TYPE_SCHEM, NULL AS TYPE_NAME, NULL AS SELF_REFERENCING_COL_NAME, NULL AS REF_GENERATION FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = 'abc' HAVING TABLE_TYPE IN ('LOCAL TEMPORARY','TABLE','VIEW',null,null) ORDER BY TABLE_TYPE, TABLE_SCHEMA, TABLE_NAME;
having的问题，执行返回empty set

1 year ago mysql连接方式报错是找不到系统变量，建议errorSystemVariableDoesNotExist这个报错打印一下具体变量名，这样也许可以通过加一些系统变量的方式来达到兼容。
后面group by的错误是其他数据库(jdbc)这个连接方式报的，我们甚至都没法知道它用的什么标准。

7 months ago @WuMenglong 暂时有个绕行方法：可以先用mysql odbc 驱动版本：8.0.26试一下，见 https://github.com/matrixorigin/matrixone/issues/13997#issuecomment-2078555783

2 weeks ago suggest support on version 2.1.0
Is there an existing issue for the same bug?
Environment
Actual Behavior
1、ODBC连接报错 在 Tableau 中使用 MySQL连接器（ODBC方式）连接MatrixOne，会直接报错： [MySQL][ODBC 8.0(w) Driver]internal error: the system variable does not exist
2、JDBC连接报错 使用 Tableau 中通用的 JDBC 方式，驱动使用 mysql-connector-j-8.0.33.jar，可以正常登录，登录后选择数据库时出现报错：SQL syntax error: column "tables.table_type" must appear in the GROUP BY clause or be used in an aggregate function.
3、调整SQL_MODE后不可用 根据 JDBC 下的报错，尝试调整 MatrixOne 的 SQL_MODE，去掉其中的 ONLY_FULL_GROUP_BY：
set global sql_mode='ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION,NO_ZERO_DATE,NO_ZERO_IN_DATE,ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES';修改完成后，JDBC 连接时不再报错，但数据库中也无法正常的展示表信息。Expected Behavior
