Incorrect syntax near the keyword 'ON'.

通常出现“Incorrect syntax near the keyword…”的错误信息是由于 SQL 语句中出现了语法错误。在你的情况中,错误位于 ON 关键字。常见的 ON 错误包括:
1. JOIN 语句中 ON 子句错误。请检查 JOIN 语句中 ON 子句的语法是否正确,包括表名、列名和运算符等是否正确。
2. WHERE 子句中的 ON 错误。ON 关键字只在 JOIN 中使用,如果在 WHERE 子句中使用会导致语法错误。
3. 子查询中的 ON 错误。如果你在子查询中使用了 ON 关键字,可能需要确保它被正确地包含在 JOIN 语句中。
你可以仔细检查你的 SQL 语句,并参考 SQL 语法手册来查找错误并进行修改。

Incorrect syntax near 'FORCE'.
This error message typically occurs in SQL when the keyword "FORCE" is used incorrectly or in an unsupported way.
Here are a few possible causes and solutions for this error:
1. Using "FORCE" as a keyword in a SQL statement:
- Solution: "FORCE" is not a valid SQL keyword, so you should remove it or replace it with a valid keyword.
2. Using "FORCE" as a column name or table name:
- Solution: If you have a column or table named "FORCE", you should rename it to something else. "FORCE" is not a good name for a database object because it is a reserved keyword in some contexts.
3. Using "FORCE" in a statement that is not supported by your database system:
- Solution: Some SQL statements or clauses may not be supported by all database systems, so you should check the documentation for your database to see if "FORCE" is a valid keyword. If it is not, you may need to rephrase your statement or use a different approach.
Overall, the best way to avoid this error is to carefully review your SQL code and make sure that all keywords, identifiers, and statements are valid and supported by your database system.
执行你上面那句命令报Incorrect syntax near 'sys'.的错误
如果您在 SQL Server 中执行该命令时遇到 "Incorrect syntax near 'sys'" 错误,可能是由于您的 SQL Server 版本太低导致的。在 SQL Server 2005 或更早版本中,可能不支持使用 sys.foreign_keys 系统视图。
在这种情况下,您可以尝试使用以下命令查看 DocBase 表的外键关联情况:
```
SELECT
FK.name AS ForeignKey,
TP.name AS ParentTable,
TR.name AS ReferenceTable
FROM
sys.foreign_keys FK
INNER JOIN sys.tables TP ON FK.parent_object_id = TP.object_id
INNER JOIN sys.tables TR ON FK.referenced_object_id = TR.object_id
WHERE
TP.name = 'DocBase'
```
其中,'DocBase' 是要查看外键关联的表的名称,可以根据实际情况修改。
此命令也会列出 DocBase 表作为外键父表或外键子表的所有外键关联的名称和相关表的名称。
