List all tables with Row count in sql server

Simple one

SELECT      SCHEMA_NAME(A.schema_id) + '.' +
        A.Name, SUM(B.rows) AS 'RowCount'
FROM        sys.objects A
INNER JOIN sys.partitions B ON A.object_id = B.object_id
WHERE       A.type = 'U'
GROUP BY    A.schema_id, A.Name

GO


Type 1

SELECT 
    TableName = t.NAME,
    TableSchema = s.Name,
    RowCounts = p.rows
FROM 
    sys.tables t
INNER JOIN 
    sys.schemas s ON t.schema_id = s.schema_id
INNER JOIN      
    sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN 
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
WHERE 
    t.is_ms_shipped = 0
GROUP BY
    t.NAME, s.Name, p.Rows
ORDER BY 

    s.Name, t.Name

Type 2  using CTE

WITH CountRowsInTables (Table_Name, Table_Schema, Row_Counts) AS
(
SELECT 
TableName = t.Name,
TableSchema = s.Name,
RowCounts = p.Rows
    FROM 
        sys.tables t
    INNER JOIN

        t.is_ms_shipped = 0
    GROUP BY
        s.Name, t.Name, p.Rows
)

SELECT Table_name, Table_Schema, Row_Counts

    FROM CountRowsInTables

Type 3

SELECT 
    sc.name +'.'+ ta.name TableName, SUM(pa.rows) RowCnt
FROM 
    sys.tables ta
INNER JOIN sys.partitions pa
    ON pa.OBJECT_ID = ta.OBJECT_ID
INNER JOIN sys.schemas sc
    ON ta.schema_id = sc.schema_id
WHERE ta.is_ms_shipped = 0 AND pa.index_id IN (1,0)
GROUP BY sc.name,ta.name

ORDER BY SUM(pa.rows) DESC

Type 4 using Dynamic SQL

DECLARE @sql nvarchar(MAX)

SELECT
    @sql = COALESCE(@sql + ' UNION ALL ', '') +
        'SELECT
            ''' + s.name + ''' AS ''Schema'',
            ''' + t.name + ''' AS ''Table'',
            COUNT(*) AS Count
            FROM ' + QUOTENAME(s.name) + '.' + QUOTENAME(t.name)
    FROM sys.schemas s
    INNER JOIN sys.tables t ON t.schema_id = s.schema_id
    ORDER BY
        s.name,
        t.name


EXEC(@sql)


Type 5  list of table with row count and size

SELECT
  t.Name                                       AS TableName,
  s.Name                                       AS SchemaName,

  SUM(a.total_pages) * 8                       AS TotalSpaceKB,
  SUM(a.used_pages) * 8                        AS UsedSpaceKB,

  LEFT OUTER JOIN sys.schemas s ON t.schema_id = s.schema_id
WHERE
  t.Name NOT LIKE 'dt%'
  AND t.is_ms_shipped = 0
  AND i.object_id > 255
GROUP BY
  t.Name, s.Name, p.Rows
ORDER BY
  t.Name;
