我创建了一个 SQLite 数据库。它在没有虚拟表的情况下运行良好，但是当我在代码中添加虚拟表时，它会发送以下错误。

我创建了一个数据库：

sqls = ["CREATE INDEX companyIdIdx ON one(companyId)",
        "CREATE INDEX companyIdIdxIndTree ON two(companyId)",
        "CREATE INDEX companyIdBusinessDesc ON three(companyId)",
        "CREATE VIRTUAL TABLE DescTbl USING FTS5(companyId,businessDescription)",
        "INSERT INTO DescTbl SELECT companyId,businessDescription FROM ciqBusinessDescription"]

for sql in sqls :
    try :
        basecon.execute(sql)
    except Exception as e :
        print(e.args)
        pass
    
basecon.commit()

然后我运行代码：

pd.read_sql("SELECT * FROM sqlite_master",con)

这给出了错误：

--------------------------------------------------------------------------

   1682             return cur

DatabaseError: malformed database schema (DescTbl_config) - near "WITHOUT": syntax error

The above exception was the direct cause of the following exception:
