Table 普通 Table 表达式 (CTE) 查询中的 RowCount？

Question

我正在尝试在我的输出中获取记录计数...但在语法上遇到困难。看不出我做错了什么....请帮忙

SELECT 
    InfoSchema.table_catalog + '.' + 
    InfoSchema.Table_Schema + '.' +
    InfoSchema.Table_Name as PhysicalName,
    CONVERT(char(10), SysObj.crdate,126) as Created,
    SysInx.rows Records
    
FROM 
    INFORMATION_SCHEMA.TABLES AS InfoSchema left join
    SYSOBJECTS AS SysObj ON InfoSchema.TABLE_NAME = SysObj.name

WHERE 
    TABLE_TYPE = 'BASE TABLE' 
    AND SysObj.crdate is not null
    AND SysObj.id = (
                        SELECT MIN(SysInx.id), rows
                        FROM SYSINDEXES AS SysInx
                        WHERE SysInx.id = SysObj.id
                    )

期望的输出是这样的：

PhysicalName     Created      RowCount
--------------+------------+-------------
tableName1      2020-01-01    127653
tableName2      2018-01-01    234098
tableName3      2019-01-01    0

在结果列中使用子查询。

SELECT 
    ...
    (
       SELECT MAX(rows)
         FROM SYSINDEXES AS SysInx
        WHERE SysInx.id = SysObj.id
    ) AS Records
    
FROM 
    ...

WHERE 
    ...
    AND SysObj.id IN (
                        SELECT SysInx.id
                        FROM SYSINDEXES AS SysInx
                     )
