Find database location of a table - sql

I have several databases in my SQL Server 2008. And I forgot where some tables from, so I need to ask if there's a such query that finds the database location of a certain table?
I need something goes like this:
SELECT DATABASE_NAME FROM SQLSERVER WHERE TABLE= "TBL_PRODUCTS"
Addition:
Now, i need to know the database location of certain Views and Stored Procedures
Something like this:
SELECT DATABASE_NAME FROM SQLSERVER WHERE VIEW= "VW_PRODUCTS"
SELECT DATABASE_NAME FROM SQLSERVER WHERE StoredProcedure= "SP_PRODUCTS"
Thanks!

The following procedure will do the job:
CREATE PROCEDURE usp_FindTableNameInAllDatabase
#TableName VARCHAR(256)
AS
DECLARE #DBName VARCHAR(256)
DECLARE #varSQL VARCHAR(512)
DECLARE #getDBName CURSOR
SET #getDBName = CURSOR FOR
SELECT name
FROM sys.databases
CREATE TABLE #TmpTable (DBName VARCHAR(256),
SchemaName VARCHAR(256),
TableName VARCHAR(256))
OPEN #getDBName
FETCH NEXT
FROM #getDBName INTO #DBName
WHILE ##FETCH_STATUS = 0
BEGIN
SET #varSQL = 'USE ' + #DBName + ';
INSERT INTO #TmpTable
SELECT '''+ #DBName + ''' AS DBName,
SCHEMA_NAME(schema_id) AS SchemaName,
name AS TableName
FROM sys.tables
WHERE name LIKE ''%' + #TableName + '%'''
EXEC (#varSQL)
FETCH NEXT
FROM #getDBName INTO #DBName
END
CLOSE #getDBName
DEALLOCATE #getDBName
SELECT *
FROM #TmpTable
DROP TABLE #TmpTable
GO
EXEC usp_FindTableNameInAllDatabase 'Address'
GO
The result would look like that:
Source

Do this
Use Master
Go
select
'select '''+CAST(name as varchar(200))+''' from '+CAST(name as varchar(200))+'.sys.tables where name = yourTableName'
from sysdatabases
replacing yourTableName with the name of your table, with ' '
You will get selects; then run those and will get the results.
If there are more than 100 databases, use results to text, because to grid, you will only get 100 selects maximum

Displaying multiple database tables in one table

I have multiple databases with the same table (an Eventlog with different values). The names of these databases are subject to change. I am trying to display the Eventlog tables in one consolidated table with the corresponding database name.
I tried to using cursor and dynamic SQL statement to achieve this with no luck. As well, I'm not sure if that is the best approach. Would love some help!
-- Create a new table variable to record all the database name
DECLARE #Database_Table table ([TimeStamp] nvarchar(500)
,[EventIDNo] nvarchar(100)
,[EventDesc] nvarchar(1000))
--Create variable for database name and query variable
DECLARE #DB_Name VARCHAR(100) -- database name
DECLARE #query NVARCHAR(1000) -- query variable
--Declare the cursor
DECLARE db_cursor CURSOR FOR
-- Populate the cursor with the selected database name
SELECT name
FROM sys.databases
WHERE name NOT IN ('master','model','msdb','tempdb')
--Open the cursor
OPEN db_cursor
--Moves the cursor to the first point and put that in variable name
FETCH NEXT FROM db_cursor INTO #DB_Name
-- while loop to go through all the DB selected
WHILE ##FETCH_STATUS = 0
BEGIN
SET #query = N'INSERT INTO #Database_Table
SELECT #DB_Name, *
FROM ['+ #DB_Name +'].dbo.EventLog_vw as A'
EXEC (#query)
--Fetch the next record from the cursor
FETCH NEXT FROM db_cursor INTO #DB_Name
END
--Close and deallocate cursor
CLOSE db_cursor
DEALLOCATE db_cursor
SELECT *
FROM #Database_Table
If you need a single resultset and all tables have the same layout, this should work:
DECLARE #sql nvarchar(4000) =
(SELECT STRING_AGG(CONCAT(
'SELECT ''',
QUOTENAME(name),
''',
* FROM ',
QUOTENAME(name),
'..Table ',
CHAR(10)
), ' UNION ALL ' + CHAR(10))
FROM sys.databases);
SELECT #sql; -- for checking
EXEC(#sql);
If you're on compatibility level 130 or lower, you will have to use XML PATH(TYPE, '') to aggregate. I will leave that to you.
I notice a bug in this code:
SET #query = N'INSERT INTO #Database_Table
SELECT #DB_Name, *
FROM ['+ #DB_Name +'].dbo.EventLog_vw as A'
In the SELECT clause you reference #DB_Name inside the string itself without concatenating the value as a variable. You did do this correctly in the FROM clause.
Something like:
SET #query = N'INSERT INTO #Database_Table
SELECT ''' + #DB_Name + ''', *
FROM ['+ #DB_Name +'].dbo.EventLog_vw as A'

Stored procedure to drop the column in SQL Server

I created many tables and I have noticed that I have created one useless column in all the tables. I want to create a stored procedure which will drop one specific column and can be useful in all the column.
I created this stored procedure but I'm getting an error. Help me please
You cannot parametrize table and column names with parameters - those are only valid for values - not for object names.
If this is a one-time operation, the simplest option would be to generate the ALTER TABLE ... DROP COLUMN ... statements in SSMS using this code:
SELECT
'ALTER TABLE ' + SCHEMA_NAME(t.schema_id) + '.' + t.Name +
' DROP COLUMN Phone;'
FROM
sys.tables t
and then execute this code in SSMS; the output from it is a list of statement which you can then copy & paste to a new SSMS window and execute.
If you really want to do this as a stored procedure, you can apply the same basic idea - and then just use code (a cursor) to iterate over the commands being generated, and executing them - something like this:
CREATE PROCEDURE dbo.DropColumnFromAllTables (#ColumnName NVARCHAR(100))
AS
BEGIN
DECLARE #SchemaName sysname, #TableName sysname
-- define cursor over all tables which contain this column in question
DECLARE DropCursor CURSOR LOCAL FAST_FORWARD
FOR
SELECT
SchemaName = s.Name,
TableName = t.Name
FROM
sys.tables t
INNER JOIN
sys.schemas s ON t.schema_id = s.schema_id
WHERE
EXISTS (SELECT * FROM sys.columns c
WHERE c.object_id = t.object_id
AND c.Name = #ColumnName);
-- open cursor and start iterating over the tables found
OPEN DropCursor
FETCH NEXT FROM DropCursor INTO #SchemaName, #TableName
WHILE ##FETCH_STATUS = 0
BEGIN
DECLARE #Stmt NVARCHAR(1000)
-- generate the SQL statement
SET #Stmt = N'ALTER TABLE [' + #SchemaName + '].[' + #TableName + '] DROP COLUMN [' + #ColumnName + ']';
-- execute that SQL statement
EXEC sp_executeSql #Stmt
FETCH NEXT FROM DropCursor INTO #SchemaName, #TableName
END
CLOSE DropCursor
DEALLOCATE DropCursor
END
This procedure should work.
It loops through all cols and then deletes the column where sum(col) is zero.
Take a Backup of the Table
alter procedure deletecolumnsifzero #tablename varchar(1000)
as
set nocount on
declare #n int
declare #sql nvarchar(1000)
declare #sum_cols nvarchar(1000)
declare #c_id nvarchar(100)
set #n = 0
declare c1 cursor for
select column_name from information_schema.columns
where
table_name like #tablename
--Cursor Starts
open c1
fetch next from c1
into #c_id
while ##fetch_status = 0
begin
set #sql=''
set #sql='select #sum_cols = sum('+#c_id+') from ['+#tablename+']'
exec sp_Executesql #sql,N'#sum_cols int out,#tablename nvarchar(100)',#sum_cols out,#tablename
if(#sum_cols = 0)
begin
set #n=#n+1
set #sql=''
set #sql= #sql+'alter table ['+#tablename+'] drop column ['+#c_id+']'
exec sp_executesql #sql
end
fetch next from c1

SQL get max id value from all tables in all databases

I want to get the database name, schema name, table name and max id value from all tables in all databases. Using following query I get the DBname, Schema and TableName but cannot figure out how to get the max(id) value also into the table.
DECLARE #DBName VARCHAR(256)
DECLARE #varSQL VARCHAR(256)
DECLARE #getDBName CURSOR
SET #getDBName = CURSOR FOR SELECT name FROM sys.databases
CREATE TABLE #TmpTable (
DBName VARCHAR(256),
SchemaName VARCHAR(256),
TableName VARCHAR(256)
)
OPEN #getDBName
FETCH NEXT FROM #getDBName INTO #DBName
WHILE ##FETCH_STATUS = 0
BEGIN
SET #varSQL = 'USE ' + #DBName + ';
INSERT INTO #TmpTable
SELECT '''+ #DBName + ''' AS DBName,
SCHEMA_NAME(schema_id) AS SchemaName,
name AS TableName
FROM sys.tables'
EXEC(#varSQL)
FETCH NEXT FROM #getDBName INTO #DBName
END
CLOSE #getDBName
DEALLOCATE #getDBName
SELECT * FROM #TmpTable
DROP TABLE #TmpTable
SELECT
'#DBName' AS DBName,
IDENT_CURRENT(Name) MaxId,
SCHEMA_NAME(Schema_ID) AS SchemaName,
name AS TableName
FROM sys.Tables

SQL Server look for stored procedure

I'm using SQL Server Management Studio and I have multiple server connections and I need to know where a specific stored procedure exists in every server which contains multiple databases!
Looking for a query to run on each server
Here is a little script that you could run on each server.
I know that it uses a while loop, which is generally not preferred, someone might be able to improve on it.
Run the script from the master database.
SQL Query:
set nocount on
declare #procname varchar(150) = '<SPROCNAME_TO_FIND>' -- SET THIS TO THE STORED PROCEDURE NAME YOU ARE LOOKING FOR
declare #alldbonserver table
( databasename varchar(150),
doneflag bit )
declare #foundtbl table
( countcol int,
dbname varchar(150) )
declare #errortbl table
( dbname varchar(150) )
insert #alldbonserver
( databasename,
doneflag )
select sdb.name,
0
from sys.databases sdb
declare #curdbname varchar(150),
#sqlcmd varchar(max)
while exists (select 1
from #alldbonserver
where doneflag = 0)
begin
select top 1
#curdbname = databasename
from #alldbonserver
where doneflag = 0
select #sqlcmd = 'select distinct 1, ''' + #curdbname + ''' as dbname from ' + #curdbname + '.sys.objects where type = ''P'' and name = ''' + #procname + ''''
begin try
insert #foundtbl
( countcol, dbname )
exec(#sqlcmd)
end try
begin catch
insert #errortbl
values ( #curdbname )
end catch
update #alldbonserver
set doneflag = 1
where databasename = #curdbname
end
select dbname as 'Databases with stored procedure'
from #foundtbl
select dbname as 'Unable to access databases'
from #errortbl
set nocount off
Sample output:
Databases with stored procedure
-----------------------------------------
MainDatabase
SomeOtherDatabase
Unable to access databases

If you are using SSMS, you could create a server registration group that contains all of the servers you connect to, right click on the group and run this query against the group: exec sp_MSforeachdb 'select * from [?].sys.procedures where name=''<your_name_here>'''
This query will enumerate each of the databases on each of the servers in the group (note: the single quotes are like that for a reason...)
I just put this together on SQL2012. It should return all Stored Procs on a Server for a given name. If you leave #SPName blank, you will get all of them.
The Query utilizes sys.all_objects so you could easily change it to work the same for tables, functions, any or all db objects.
DECLARE #SPName VARCHAR(256)
SET #SPName = 'My_SP_Name'
DECLARE #DBName VARCHAR(256)
DECLARE #varSQL VARCHAR(512)
DECLARE #getDBName CURSOR
SET #getDBName = CURSOR FOR
SELECT name
FROM sys.databases
CREATE TABLE #TmpTable (DBName VARCHAR(256),
SchemaName VARCHAR(256),
SPName VARCHAR(256))
OPEN #getDBName
FETCH NEXT
FROM #getDBName INTO #DBName
WHILE ##FETCH_STATUS = 0
BEGIN
SET #varSQL = 'USE [' + #DBName + '];
INSERT INTO #TmpTable
SELECT '''+ #DBName + ''' AS DBName,
SCHEMA_NAME(schema_id) AS SchemaName,
name AS SPName
FROM sys.all_objects
WHERE [type] = ''P'' AND name LIKE ''%' + #SPName + '%'''
EXEC (#varSQL)
FETCH NEXT
FROM #getDBName INTO #DBName
END
CLOSE #getDBName
DEALLOCATE #getDBName
SELECT *
FROM #TmpTable
DROP TABLE #TmpTable

Display all the names of databases containing particular table

I have many databases in my SQL Server.
I have to just search for database names containg particular table name Heartbitmaster
I have many databases such as Gotgold, DVD, etc and I just want to find database names from query that contain this table Heartbitmaster.
I searched I tried for query:
SELECT
TABLE_NAME
FROM
INFORMATION_SCHEMA.TABLES
WHERE
TABLE_TYPE = 'base table'
AND table_schema = 'Heartbitmaster'
but it didn't work.
I searched further and came across:
SELECT name, database_id, create_date
FROM sys.databases
but dont know how to arrange further where condition for search of table name
Please help me.
I got it done through following query:
SELECT name
FROM sys.databases
WHERE CASE WHEN state_desc = 'ONLINE'
THEN OBJECT_ID(QUOTENAME(name) + '.[dbo].[heartbit]', 'U')
END IS NOT NULL
sp_MSforeachdb 'SELECT "?" AS DB, * FROM [?].sys.tables WHERE name like ''%tablename%'''
try this one
I needed something slightly different.
This will return all tables and their corresponding DBs with names containing the supplied string:
SELECT TABLE_NAME, TABLE_SCHEMA
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME like '%_<insert_name_here>';
If you need to find database objects (e.g. tables, columns, triggers) by name - have a look at the FREE Red-Gate tool called SQL Search which does this - it searches your entire database for any kind of string(s).
It's a great must-have tool for any DBA or database developer - did I already mention it's absolutely FREE to use for any kind of use??
As for the INFORMATION_SCHEMA or the SQL Server specific catalog views: as far as I know, those are always constrained to the current database you're in - so you cannot search across all databases on your server. SQL Search does this for you - by searching into every single database on the server.
Create Procedure as bellow
CREATE PROCEDURE usp_FindTableNameInAllDatabase
#TableName VARCHAR(256)
AS
DECLARE #DBName VARCHAR(256)
DECLARE #varSQL VARCHAR(512)
DECLARE #getDBName CURSOR
SET #getDBName = CURSOR FOR
SELECT name
FROM sys.databases
CREATE TABLE #TmpTable (DBName VARCHAR(256),
SchemaName VARCHAR(256),
TableName VARCHAR(256))
OPEN #getDBName
FETCH NEXT
FROM #getDBName INTO #DBName
WHILE ##FETCH_STATUS = 0
BEGIN
SET #varSQL = 'USE ' + #DBName + ';
INSERT INTO #TmpTable
SELECT '''+ #DBName + ''' AS DBName,
SCHEMA_NAME(schema_id) AS SchemaName,
name AS TableName
FROM sys.tables
WHERE name LIKE ''%' + #TableName + '%'''
EXEC (#varSQL)
FETCH NEXT
FROM #getDBName INTO #DBName
END
CLOSE #getDBName
DEALLOCATE #getDBName
SELECT *
FROM #TmpTable
DROP TABLE #TmpTable
GO
EXEC usp_FindTableNameInAllDatabase 'Address'
GO
exec usp_FindTableNameInAllDatabase 'user'
It Works!!!!!!!
Run this query for finding database name for a particular table
The paste table name in #tablename
Drop table #tempo for next time run
declare #tablename varchar(max) = 'patient'
declare #count int = (select max(database_id) FROM sys.databases)
declare #n int = 1
declare #dbname varchar(max)
declare #query nvarchar(max)
create table #tempo(Databasename varchar(max), tablename varchar(max))
while #n <= #count
begin
select #dbname = name from sys.databases where database_id = #n and service_broker_guid <> '00000000-0000-0000-0000-000000000000'
set #query = 'insert into #tempo(Databasename,tablename) select '''+#dbname+''' [Database],name from '+#dbname+'.sys.tables where name like ''%'+#tablename+'%'''
exec(#query)
set #n=#n+1;
end
select * from #tempo
At the last giving error like
Database 'databasename' cannot be opened because it is offline.
then run this query separately
select * from #tempo
I Complete sp_MSforeachdb and create a procedure like this :
create PROCEDURE findTableName
#tablename nvarchar(max)
AS
BEGIN
declare #sqlCommand nvarchar(max)
CREATE TABLE #t (DBName VARCHAR(256),SchemaName VARCHAR(256),TableName VARCHAR(256))
set #sqlCommand='insert into #t (DBName,SchemaName,TableName) exec sp_MSforeachdb ''SELECT "?" AS DB, SCHEMA_NAME(schema_id) AS SchemaName ,name FROM [?].sys.tables WHERE name like ''''%'+#tablename+'%'''''''
--print #sqlCommand
exec ( #sqlCommand)
select * from #t
END
