<p>How to get all the database names and corresponding table names together ?</p>

You will have to write a store procedure.
First get the database name
```
```
SELECT Name FROM master.sys.databases
```
```
For each database
```
```
SELECT %DatabaseName%, Name FROM %DatabaseName%.SysObjects WHERE type = 'U'
```
```
Edit here's the store procedure
```
```
CREATE PROCEDURE sp_GetDatabasesTables 
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
CREATE TABLE #schema ( DatabaseName VarChar(50), TableName VarChar(50) );
DECLARE @DatabaseName varchar(50);
DECLARE cursorDatabase CURSOR FOR
    SELECT Name FROM master.sys.databases WHERE Name NOT IN ('tempdb'); -- add any table you want to filter here

OPEN cursorDatabase;

-- Perform the first fetch.
FETCH NEXT FROM cursorDatabase INTO @DatabaseName;

-- Check @@FETCH_STATUS to see if there are any more rows to fetch.
WHILE @@FETCH_STATUS = 0
BEGIN
    EXEC ('INSERT INTO #schema (DatabaseName, TableName) SELECT ''' + @DatabaseName + ''' AS DatabaseName, Name As TableName FROM ' + @DatabaseName + '.sys.SysObjects WHERE type = ''U'';');
    FETCH NEXT FROM cursorDatabase INTO @DatabaseName;
END

CLOSE cursorDatabase;
DEALLOCATE cursorDatabase;
SELECT * FROM #schema
END
```
```
