## SELECT Statement

| `SELECT` Statement and Related Clauses | Offline Mode | Online Preview Mode | Online Request Mode | Note |
|:-----------------------------------------------|--------------|---------------------|---------------------|:------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| [`SELECT Statement`](#selectexprlist) | **``✓``** | **``✓``** | **``✓``** | A list of projection operations, generally including column names, expressions, or ‘*’ for all columns. |
| [`FROM Clause`](#tablerefs) | **``✓``** | **``✓``** | **``✓``** | The FROM clause indicates the data source.<br />The data source can be one table (`select * from t;`) or multiple tables that LAST JOIN together (see [JOIN CLAUSE](../dql/JOIN_CLAUSE.md)) or no table ( `select 1+1;`), see [NO_TABLE SELECT](../dql/NO_TABLE_SELECT_CLAUSE.md) |
| [`JOIN` Clause](../dql/JOIN_CLAUSE.md) | **``✓``** | **``✓``** | **``✓``** | The JOIN clause indicates that the data source comes from multiple joined tables. OpenMLDB currently only supports LAST JOIN. For Online Request Mode, please follow [the specification of LAST JOIN under Online Request Mode](../deployment_manage/ONLINE_SERVING_REQUIREMENTS.md#the-usage-specification-of-last-join-under-online-serving) |
| [`WHERE` Clause](../dql/WHERE_CLAUSE.md) | **``✓``** | **``✓``** | | The WHERE clause is used to set filter conditions, and only the data that meets the conditions will be included in the query result. |
| [`GROUP BY` Clause](../dql/GROUP_BY_CLAUSE.md) | **``✓``** | | | The GROUP BY clause is used to group the query results.The grouping conditions only support simple columns. |
| [`HAVING` Clause](../dql/HAVING_CLAUSE.md) | **``✓``** | | | The HAVING clause is similar to the WHERE clause. The HAVING clause filters data after GROUP BY, and the WHERE clause is used to filter records before aggregation. | |

| [`WINDOW` Clause](../dql/WINDOW_CLAUSE.md) | **``✓``** | | **``✓``** | The WINDOW clause is used to define one or several windows. Windows can be named or anonymous. Users can call aggregate functions on the window to perform analysis (```sql agg_func() over window_name```). For Online Request Mode, please follow the [specification of WINDOW Clause under Online Request Mode](https://openmldb.ai/docs/en/main/reference/sql/deployment_manage/ONLINE_SERVING_REQUIREMENTS.html#window-usage-specification-under-online-serving) |
| [`LIMIT` Clause](../dql/LIMIT_CLAUSE.md) | **``✓``** | **``✓``** | **``✓``** | The LIMIT clause is used to limit the number of results. OpenMLDB currently only supports one parameter to limit the maximum number of rows of returned data. |
| `ORDER BY` Keyword | | | | Standard SQL also supports the ORDER BY keyword, however OpenMLDB does not support this keyword currently. For example, the query `SELECT * from t1 ORDER BY col1;` is not supported in OpenMLDB. |
