The following query selects all database roles, which member is #myUser:
SELECT
p.name AS userRoleName
FROM sys.database_role_members rm
INNER JOIN sys.database_principals p ON p.principal_id = rm.role_principal_id
INNER JOIN sys.database_principals m ON m.principal_id = rm.member_principal_id
WHERE m.name = #myUser;
For each databaase roles listed above I have to run:
ALTER ROLE [database_role_name] DROP MEMBER #myUser;
How to combine two above queries in one T-SQL procedure?
We can do this with dynamic SQL. I assume you have STRING_AGG available in your version of SQL Server:
DECLARE #sql nvarchar(max) =
(SELECT
STRING_AGG(
CAST(N'ALTER ROLE ' + QUOTENAME(p.name) + N' DROP MEMBER ' + QUOTENAME(#myUser) + N';'
AS nvarchar(max))
, NCHAR(10))
FROM sys.database_role_members rm
INNER JOIN sys.database_principals p ON p.principal_id = rm.role_principal_id
INNER JOIN sys.database_principals m ON m.principal_id = rm.member_principal_id
WHERE m.name = #myUser
);
-- PRINT #sql -- for testing
EXEC (#sql)
I'm trying to iterate through all databases by listing all table constraints. I've achieved the following:
DECLARE #sql nvarchar(max) = ''
SET #sql =
'
USE ?
select con.[name] as constraint_name,
schema_name(t.schema_id) + ''.'' + t.[name] as [table],
col.[name] as column_name,
con.[definition],
case when con.is_disabled = 0
then ''Active''
else ''Disabled''
end as [status]
from sys.check_constraints con
left outer join sys.objects t
on con.parent_object_id = t.object_id
left outer join sys.all_columns col
on con.parent_column_id = col.column_id
and con.parent_object_id = col.object_id
order by con.name
'
PRINT #sql
EXEC sp_MSforeachdb #sql
I would like to have the query UNION all of my results in one clean select.
Can anyone help?
Using SQL Server 2016.
One way is to insert the intermediate results into a temp table. Below is an example that also includes the database name in the results.
CREATE TABLE #results (
[database_name] sysname
,[constraint_name] nvarchar(128)
,[table] nvarchar(257)
,[column_name] nvarchar(128)
,[definition] nvarchar(max)
,[status] varchar(8)
);
DECLARE #sql nvarchar(max) = ''
SET #sql =
N'
USE [?];
INSERT INTO #results
select
N''?'' as database_name,
con.[name] as constraint_name,
schema_name(t.schema_id) + ''.'' + t.[name] as [table],
col.[name] as column_name,
con.[definition],
case when con.is_disabled = 0
then ''Active''
else ''Disabled''
end as [status]
from sys.check_constraints con
left outer join sys.objects t
on con.parent_object_id = t.object_id
left outer join sys.all_columns col
on con.parent_column_id = col.column_id
and con.parent_object_id = col.object_id;
';
PRINT #sql;
EXEC sp_MSforeachdb #sql;

If you're using SQL Server 2005 and up, you can also use this:
SELECT
t.NAME AS TableName,
i.name as indexName,
p.[Rows],
sum(a.total_pages) as TotalPages,
sum(a.used_pages) as UsedPages,
sum(a.data_pages) as DataPages,
(sum(a.total_pages) * 8) / 1024 as TotalSpaceMB,
(sum(a.used_pages) * 8) / 1024 as UsedSpaceMB,
(sum(a.data_pages) * 8) / 1024 as DataSpaceMB
FROM
sys.tables t
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
INNER JOIN
sys.allocation_units a ON p.partition_id = a.container_id
WHERE
t.NAME NOT LIKE 'dt%' AND
i.OBJECT_ID > 255 AND
i.index_id <= 1
GROUP BY
t.NAME, i.object_id, i.index_id, i.name, p.[Rows]
ORDER BY
object_name(i.object_id)
In my opinion, it's easier to handle than the sp_msforeachtable output.
A snippet I found at http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=21021 that helped me:
select t.name TableName, i.rows Records
from sysobjects t, sysindexes i
where t.xtype = 'U' and i.id = t.id and i.indid in (0,1)
order by TableName;
To get that information in SQL Management Studio, right click on the database, then select Reports --> Standard Reports --> Disk Usage by Table.
SELECT
T.NAME AS 'TABLE NAME',
P.[ROWS] AS 'NO OF ROWS'
FROM SYS.TABLES T
INNER JOIN SYS.PARTITIONS P ON T.OBJECT_ID=P.OBJECT_ID;
As seen here, this will return correct counts, where methods using the meta data tables will only return estimates.

Well luckily SQL Server management studio gives you a hint on how to do this.
Do this,
start a SQL Server trace and open the activity you are doing (filter
by your login ID if you're not alone and set the application Name
to Microsoft SQL Server Management Studio), pause the trace and discard any results you have recorded till now;
Then, right click a table and select property from the pop up menu;
start the trace again;
Now in SQL Server Management studio select the storage property item on the left;
Pause the trace and have a look at what TSQL is generated by microsoft.
In the probably last query you will see a statement starting with exec sp_executesql N'SELECT
when you copy the executed code to visual studio you will notice that this code generates all the data the engineers at microsoft used to populate the property window.
when you make moderate modifications to that query you will get to something like this:
SELECT
SCHEMA_NAME(tbl.schema_id)+'.'+tbl.name as [table], --> something I added
p.partition_number AS [PartitionNumber],
prv.value AS [RightBoundaryValue],
fg.name AS [FileGroupName],
CAST(pf.boundary_value_on_right AS int) AS [RangeType],
CAST(p.rows AS float) AS [RowCount],
p.data_compression AS [DataCompression]
FROM sys.tables AS tbl
INNER JOIN sys.indexes AS idx ON idx.object_id = tbl.object_id and idx.index_id < 2
INNER JOIN sys.partitions AS p ON p.object_id=CAST(tbl.object_id AS int) AND p.index_id=idx.index_id
LEFT OUTER JOIN sys.destination_data_spaces AS dds ON dds.partition_scheme_id = idx.data_space_id and dds.destination_id = p.partition_number
LEFT OUTER JOIN sys.partition_schemes AS ps ON ps.data_space_id = idx.data_space_id
LEFT OUTER JOIN sys.partition_range_values AS prv ON prv.boundary_id = p.partition_number and prv.function_id = ps.function_id
LEFT OUTER JOIN sys.filegroups AS fg ON fg.data_space_id = dds.data_space_id or fg.data_space_id = idx.data_space_id
LEFT OUTER JOIN sys.partition_functions AS pf ON pf.function_id = prv.function_id
Now the query is not perfect and you could update it to meet other questions you might have, the point is, you can use the knowledge of microsoft to get to most of the questions you have by executing the data you're interested in and trace the TSQL generated using profiler.
I kind of like to think that MS engineers know how SQL server work and, it will generate TSQL that works on all items you can work with using the version on SSMS you are using so it's quite good on a large variety releases prerviouse, current and future.
And remember, don't just copy, try to understand it as well else you might end up with the wrong solution.

This approaches uses string concatenation to produce a statement with all tables and their counts dynamically, like the example(s) given in the original question:
SELECT COUNT(*) AS Count,'[dbo].[tbl1]' AS TableName FROM [dbo].[tbl1]
UNION ALL SELECT COUNT(*) AS Count,'[dbo].[tbl2]' AS TableName FROM [dbo].[tbl2]
UNION ALL SELECT...
Finally this is executed with EXEC:
DECLARE #cmd VARCHAR(MAX)=STUFF(
(
SELECT 'UNION ALL SELECT COUNT(*) AS Count,'''
+ QUOTENAME(t.TABLE_SCHEMA) + '.' + QUOTENAME(t.TABLE_NAME)
+ ''' AS TableName FROM ' + QUOTENAME(t.TABLE_SCHEMA) + '.' + QUOTENAME(t.TABLE_NAME)
FROM INFORMATION_SCHEMA.TABLES AS t
WHERE TABLE_TYPE='BASE TABLE'
FOR XML PATH('')
),1,10,'');
EXEC(#cmd);
The first thing that came to mind was to use sp_msForEachTable
exec sp_msforeachtable 'select count(*) from ?'
that does not list the table names though, so it can be extended to
exec sp_msforeachtable 'select parsename(''?'', 1), count(*) from ?'
The problem here is that if the database has more than 100 tables you will get the following error message:
The query has exceeded the maximum
number of result sets that can be
displayed in the results grid. Only
the first 100 result sets are
displayed in the grid.
So I ended up using table variable to store the results
declare #stats table (n sysname, c int)
insert into #stats
exec sp_msforeachtable 'select parsename(''?'', 1), count(*) from ?'
select
*
from #stats
order by c desc

Here is my take on this question. It contains all schemas and lists only tables with rows. YMMV
select distinct schema_name(t.schema_id) as schema_name, t.name as
table_name, p.[Rows]
from sys.tables as t
INNER JOIN sys.indexes as 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 p.[Rows] > 0
order by schema_name;
If you use MySQL >4.x you can use this:
select TABLE_NAME, TABLE_ROWS from information_schema.TABLES where TABLE_SCHEMA="test";
Keep in mind that for some storage engines, TABLE_ROWS is an approximation.
The accepted answer didn't work for me on Azure SQL, here's one that did, it's super fast and did exactly what I wanted:
select t.name, s.row_count
from sys.tables t
join sys.dm_db_partition_stats s
ON t.object_id = s.object_id
and t.type_desc = 'USER_TABLE'
and t.name not like '%dss%'
and s.index_id = 1
order by s.row_count desc
You could try this:
SELECT OBJECT_SCHEMA_NAME(ps.object_Id) AS [schemaname],
OBJECT_NAME(ps.object_id) AS [tablename],
row_count AS [rows]
FROM sys.dm_db_partition_stats ps
WHERE OBJECT_SCHEMA_NAME(ps.object_Id) <> 'sys' AND ps.index_id < 2
ORDER BY
OBJECT_SCHEMA_NAME(ps.object_Id),
OBJECT_NAME(ps.object_id)
This sql script gives the schema, table name and row count of each table in a database selected:
SELECT SCHEMA_NAME(schema_id) AS [SchemaName],
[Tables].name AS [TableName],
SUM([Partitions].[rows]) AS [TotalRowCount]
FROM sys.tables AS [Tables]
JOIN sys.partitions AS [Partitions]
ON [Tables].[object_id] = [Partitions].[object_id]
AND [Partitions].index_id IN ( 0, 1 )
-- WHERE [Tables].name = N'name of the table'
GROUP BY SCHEMA_NAME(schema_id), [Tables].name
order by [TotalRowCount] desc
Ref: https://blog.sqlauthority.com/2017/05/24/sql-server-find-row-count-every-table-database-efficiently/
Another way of doing this:
SELECT o.NAME TABLENAME,
i.rowcnt
FROM sysindexes AS i
INNER JOIN sysobjects AS o ON i.id = o.id
WHERE i.indid < 2 AND OBJECTPROPERTY(o.id, 'IsMSShipped') = 0
ORDER BY i.rowcnt desc
I think that the shortest, fastest and simplest way would be:
SELECT
object_name(object_id) AS [Table],
SUM(row_count) AS [Count]
FROM
sys.dm_db_partition_stats
WHERE
--object_schema_name(object_id) = 'dbo' AND
index_id < 2
GROUP BY
object_id

Shnugo's answer is the ONLY one that works in Azure with Externa Tables. (1) Azure SQL doesn't support sp_MSforeachtable at all and (2) rows in sys.partitions for an External table is always 0.
select T.object_id, T.name, I.indid, I.rows
from Sys.tables T
left join Sys.sysindexes I
on (I.id = T.object_id and (indid =1 or indid =0 ))
where T.type='U'
Here indid=1 means a CLUSTERED index and indid=0 is a HEAP
Currently i have to create a list of all tables & schemes used in several (terribly) long SQL statements.
Of course i could go manually through the SQL statements and write down every table used in a JOIN, Subselect and so on.
But i'd be curious if there is any easier way to do it. maybe with a "simple" SQL statement, but i have no clue how to do it.
Why am i asking? I'd have to do this for about 50 SQL-Unload-Statements, where all of them use between 30 and 70 tables. I guess you can imagine this quite boring work
Thanks in advance for any input & hints!
Have a read here: How can i get the list of tables in the stored procedure
;WITH stored_procedures AS (
SELECT
o.name AS proc_name, oo.name AS table_name,
ROW_NUMBER() OVER(partition by o.name,oo.name ORDER BY o.name,oo.name) AS row
FROM sysdepends d
INNER JOIN sysobjects o ON o.id=d.id
INNER JOIN sysobjects oo ON oo.id=d.depid
WHERE o.xtype = 'P')
SELECT proc_name, table_name FROM stored_procedures
WHERE row = 1
ORDER BY proc_name,table_name
All credit to the OP of the code above in the thread above.
I will post this answer & mark it as solved, as it was the best and easiest way to solve my issue.
Hint was in a comment by #whereisSQL (thanks a lot!)
Seems like it was already asked in this thread, but i didn't find it:
https://dba.stackexchange.com/questions/121346/need-to-get-identify-all-tables-and-columns-in-a-sql-query/121355#121355
There is an online "get table column" tool to list the tables of a SQL statement here:
http://107.170.101.241:8080/getTableColumn/
It lists all tables and additionally columns used in the statement! Perfect solution in my case.

Now the query is not perfect and you could update it to meet other questions you might have, the point is, you can use the knowledge of microsoft to get to most of the questions you have by executing the data you're interested in and trace the TSQL generated using profiler.
I kind of like to think that MS engineers know how SQL server work and, it will generate TSQL that works on all items you can work with using the version on SSMS you are using so it's quite good on a large variety releases prerviouse, current and future.
And remember, don't just copy, try to understand it as well else you might end up with the wrong solution.

This approaches uses string concatenation to produce a statement with all tables and their counts dynamically, like the example(s) given in the original question:
SELECT COUNT(*) AS Count,'[dbo].[tbl1]' AS TableName FROM [dbo].[tbl1]
UNION ALL SELECT COUNT(*) AS Count,'[dbo].[tbl2]' AS TableName FROM [dbo].[tbl2]
UNION ALL SELECT...
Finally this is executed with EXEC:
DECLARE #cmd VARCHAR(MAX)=STUFF(
(
SELECT 'UNION ALL SELECT COUNT(*) AS Count,'''
+ QUOTENAME(t.TABLE_SCHEMA) + '.' + QUOTENAME(t.TABLE_NAME)
+ ''' AS TableName FROM ' + QUOTENAME(t.TABLE_SCHEMA) + '.' + QUOTENAME(t.TABLE_NAME)
FROM INFORMATION_SCHEMA.TABLES AS t
WHERE TABLE_TYPE='BASE TABLE'
FOR XML PATH('')
),1,10,'');
EXEC(#cmd);
The first thing that came to mind was to use sp_msForEachTable
exec sp_msforeachtable 'select count(*) from ?'
that does not list the table names though, so it can be extended to
exec sp_msforeachtable 'select parsename(''?'', 1), count(*) from ?'
The problem here is that if the database has more than 100 tables you will get the following error message:
The query has exceeded the maximum
number of result sets that can be
displayed in the results grid. Only
the first 100 result sets are
displayed in the grid.
So I ended up using table variable to store the results
declare #stats table (n sysname, c int)
insert into #stats
exec sp_msforeachtable 'select parsename(''?'', 1), count(*) from ?'
select
*
from #stats
order by c desc
Fastest way to find row count of all tables in SQL Refreence (http://www.codeproject.com/Tips/811017/Fastest-way-to-find-row-count-of-all-tables-in-SQL)
SELECT T.name AS [TABLE NAME], I.rows AS [ROWCOUNT]
FROM sys.tables AS T
INNER JOIN sys.sysindexes AS I ON T.object_id = I.id
AND I.indid < 2
ORDER BY I.rows DESC
I want to share what's working for me
SELECT

FROM
sys.objects AS sOBJ
INNER JOIN sys.dm_db_partition_stats AS sdmvPTNS
ON sOBJ.object_id = sdmvPTNS.object_id

sOBJ.type = 'U'
AND sOBJ.is_ms_shipped = 0x0
AND sdmvPTNS.index_id < 2
GROUP BY

Here is my take on this question. It contains all schemas and lists only tables with rows. YMMV
select distinct schema_name(t.schema_id) as schema_name, t.name as
table_name, p.[Rows]
from sys.tables as t
INNER JOIN sys.indexes as 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 p.[Rows] > 0
order by schema_name;
If you use MySQL >4.x you can use this:
select TABLE_NAME, TABLE_ROWS from information_schema.TABLES where TABLE_SCHEMA="test";
Keep in mind that for some storage engines, TABLE_ROWS is an approximation.
The accepted answer didn't work for me on Azure SQL, here's one that did, it's super fast and did exactly what I wanted:
select t.name, s.row_count
from sys.tables t
join sys.dm_db_partition_stats s
ON t.object_id = s.object_id
and t.type_desc = 'USER_TABLE'
and t.name not like '%dss%'
and s.index_id = 1
order by s.row_count desc
You could try this:
SELECT OBJECT_SCHEMA_NAME(ps.object_Id) AS [schemaname],
OBJECT_NAME(ps.object_id) AS [tablename],
row_count AS [rows]
FROM sys.dm_db_partition_stats ps
WHERE OBJECT_SCHEMA_NAME(ps.object_Id) <> 'sys' AND ps.index_id < 2
ORDER BY
OBJECT_SCHEMA_NAME(ps.object_Id),
OBJECT_NAME(ps.object_id)
This sql script gives the schema, table name and row count of each table in a database selected:
SELECT SCHEMA_NAME(schema_id) AS [SchemaName],
[Tables].name AS [TableName],
SUM([Partitions].[rows]) AS [TotalRowCount]
FROM sys.tables AS [Tables]
JOIN sys.partitions AS [Partitions]
ON [Tables].[object_id] = [Partitions].[object_id]
AND [Partitions].index_id IN ( 0, 1 )
-- WHERE [Tables].name = N'name of the table'
GROUP BY SCHEMA_NAME(schema_id), [Tables].name
order by [TotalRowCount] desc
Ref: https://blog.sqlauthority.com/2017/05/24/sql-server-find-row-count-every-table-database-efficiently/
Another way of doing this:
SELECT o.NAME TABLENAME,
i.rowcnt
FROM sysindexes AS i
INNER JOIN sysobjects AS o ON i.id = o.id
WHERE i.indid < 2 AND OBJECTPROPERTY(o.id, 'IsMSShipped') = 0
ORDER BY i.rowcnt desc
I think that the shortest, fastest and simplest way would be:
SELECT
object_name(object_id) AS [Table],
SUM(row_count) AS [Count]
FROM
sys.dm_db_partition_stats
WHERE
--object_schema_name(object_id) = 'dbo' AND
index_id < 2
GROUP BY
object_id

From this question:
https://dba.stackexchange.com/questions/114958/list-all-tables-from-all-user-databases/230411#230411
I added record count to the answer provided by #Aaron Bertrand that lists all databases and all tables.
DECLARE #src NVARCHAR(MAX), #sql NVARCHAR(MAX);
SELECT #sql = N'', #src = N' UNION ALL
SELECT ''$d'' as ''database'',
s.name COLLATE SQL_Latin1_General_CP1_CI_AI as ''schema'',
t.name COLLATE SQL_Latin1_General_CP1_CI_AI as ''table'' ,
ind.rows as record_count
FROM [$d].sys.schemas AS s
INNER JOIN [$d].sys.tables AS t ON s.[schema_id] = t.[schema_id]
INNER JOIN [$d].sys.sysindexes AS ind ON t.[object_id] = ind.[id]
where ind.indid < 2';
SELECT #sql = #sql + REPLACE(#src, '$d', name)
FROM sys.databases
WHERE database_id > 4
AND [state] = 0
AND HAS_DBACCESS(name) = 1;
SET #sql = STUFF(#sql, 1, 10, CHAR(13) + CHAR(10));
PRINT #sql;
--EXEC sys.sp_executesql #sql;
You can copy, past and execute this piece of code to get all table record counts into a table. Note: Code is commented with instructions
create procedure RowCountsPro
as
begin
--drop the table if exist on each exicution
IF OBJECT_ID (N'dbo.RowCounts', N'U') IS NOT NULL
DROP TABLE dbo.RowCounts;
-- creating new table
CREATE TABLE RowCounts
( [TableName] VARCHAR(150)
, [RowCount] INT
, [Reserved] NVARCHAR(50)
, [Data] NVARCHAR(50)
, [Index_Size] NVARCHAR(50)
, [UnUsed] NVARCHAR(50))
--inserting all records
INSERT INTO RowCounts([TableName], [RowCount],[Reserved],[Data],[Index_Size],[UnUsed])
-- "sp_MSforeachtable" System Procedure, 'sp_spaceused "?"' param to get records and resources used
EXEC sp_MSforeachtable 'sp_spaceused "?"'
-- selecting data and returning a table of data
SELECT [TableName], [RowCount],[Reserved],[Data],[Index_Size],[UnUsed]
FROM RowCounts
ORDER BY [TableName]
end
I have tested this code and it works fine on SQL Server 2014.
SELECT ( Schema_name(A.schema_id) + '.' + A.NAME ) AS TableName,
Sum(B.rows)AS RecordCount
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 ;

Shnugo's answer is the ONLY one that works in Azure with Externa Tables. (1) Azure SQL doesn't support sp_MSforeachtable at all and (2) rows in sys.partitions for an External table is always 0.
select T.object_id, T.name, I.indid, I.rows
from Sys.tables T
left join Sys.sysindexes I
on (I.id = T.object_id and (indid =1 or indid =0 ))
where T.type='U'
Here indid=1 means a CLUSTERED index and indid=0 is a HEAP
