在SQL server中使用CTE报错:Incorrect syntax near the keyword ‘with’. If this statement is a common table expression WITH RowOrder AS (SELECT[Chart Number]FROM[dbo].[Patient]) 出现这种情况一般在With语句前还有其他的语句,在With前的语句末尾或者With前加上分号;即可
The CTE syntax is as follows: WITH cte_name (column_1, column_2, column_3,...) AS (cte_query_definition) SELECT * FROM cte_name; Such queries consist of two parts, and the first part is the CTE. Common Table Expressions are always introduced by the keyword WITH (that's why a...

在某些复杂查询的场景下，需要使用递归功能。通过CONNECT BY实现递归SQL是Oracle特有的方言之一，目前openGauss无法兼容CONNECT BY关键字，需要通过使用递归CTE查询替代。postgres=# SELECT *, LEVEL FROM te1 CONNECT BY PRIOR id = pid; ERROR: syntax error at or near "BY"LINE 3: CONNECT BY PRIO...

The syntax for writing a Common Table Expression in Oracle or SQL Server using the SQL WITH clause is: WITHcte_name[(column_aliases)]AS(subquery_sql_statement)SELECTcolumn_listFROMcte_name; You are able to declare multiple CTEs in a single statement, by separating them with a comma. ...

WITH common_table_expression<> 指定在 UPDATE 语句作用域内定义的临时命名结果集或视图,也称为公用表表达式 (CTE)。 CTE 结果集派生自简单查询并由 UPDATE 语句引用。 公用表表达式还可与 SELECT、INSERT、DELETE 和 CREATE VIEW 等语句一起使用。 有关详细信息,请参阅 WITH common_table_expression (Transact-...
