How do I get list of all table names in all databases on all Sql Servers using TSQL? - sql

Question

What is the best way to get the names of all of the tables in all Databases on all Sql Servers? There are many databases in many Servers. So I wanna list Server names and database names with table names.
For example
Id ServerName databaseName Tablename
1 server1 Product Vegetables
2 server2 Product Milks
3 server1 Customer People
Probably I will use following query with openquery() but I did'nt do it.
SET NOCOUNT ON
DECLARE #AllTables table (CompleteTableName nvarchar(4000))
INSERT INTO #AllTables (CompleteTableName)
EXEC sp_msforeachdb 'select ##SERVERNAME+''.''+''?''+''.''+s.name+''.''+t.name from [?].sys.tables t inner join sys.schemas s on t.schema_id=s.schema_id'
SET NOCOUNT OFF
SELECT * FROM #AllTables ORDER BY 1

delete from [DatabaseName].[dbo].[hak_tables]
declare #counter int;
declare #openquery nvarchar(2000), #tsql nvarchar(2000), #servername nvarchar(2000)
create table #temp(
id int,
servername nvarchar(50)
)
insert into #temp(id,servername)
values (1,'ServerName'),
(2,'[ServerName -2]'),
(3,'[ServerName -3]')
create table #tablehavuzu(
ID int identity (1,1),
sunucuAdi nvarchar(1000),
databaseName nvarchar(1000),
name nvarchar(1000),
type nvarchar(1000),
create_date datetime,
modify_date datetime
)
declare #cmd3 nvarchar(max)
set #counter = 1
while #counter <= (select count(1) from #temp)
begin
create table #databasename(
name nvarchar(1000),
counter int
)
set #servername = (select servername from #temp where id=#counter)
declare #sorg nvarchar(max)
set #sorg='insert into #databasename
select name,ROW_NUMBER() over(order by name asc) from '+#servername+'.master.sys.databases '
exec (#sorg)
declare #counter1 int;
set #counter1 = 1
declare #databaseCount int
set #databaseCount = (select count(1) from #databasename)
while #counter1 <= #databaseCount
begin
declare #databaseName nvarchar(1000),#sql nvarchar(1000)
begin try
set #databaseName = (select name from #databasename where counter=#counter1)
set #sql ='select ##SERVERNAME sunucuAdi, '''''+#databaseName+''''' as databaseName, name, type, create_date, modify_date from '+#servername+'.'+#databaseName+'.sys.tables'
set #cmd3= 'select * from openquery('+#servername+','''+#sql+''')'
insert into #tablehavuzu
exec (#cmd3)
end try
begin catch
end catch
set #counter1 = #counter1 +1;
end
set #counter = #counter + 1;
drop table #databasename
end
insert into [M3].[dbo].[hak_tables]
select * from #tablehavuzu
drop table #temp
drop table #tablehavuzu

The below query will list all the table of all the databases in an instance - So you can execute it in all the instances to get those -
declare #sql nvarchar(max);
select #sql =
(select ' UNION ALL
SELECT ' + + quotename(name,'''') + ' as database_name,
s.name COLLATE DATABASE_DEFAULT
AS schema_name,
t.name COLLATE DATABASE_DEFAULT as table_name
FROM '+ quotename(name) + '.sys.tables t
JOIN '+ quotename(name) + '.sys.schemas s
on s.schema_id = t.schema_id'
from sys.databases
where state=0
order by [name] for xml path(''), type).value('.', 'nvarchar(max)');
set #sql = stuff(#sql, 1, 12, '') + ' order by database_name,
schema_name,
table_name';
execute (#sql);
