SQL

declare  @Table table(Id int identity, Name varchar(100));

insert @Table(Name)
	(select t.TABLE_NAME from INFORMATION_SCHEMA.TABLES t
	join INFORMATION_SCHEMA.COLUMNS c on c.TABLE_NAME = t.TABLE_NAME
	where c.COLUMN_NAME = 'Header');

declare @Index int =0;
while(1 =1 )
begin
	set @Index += 1;
	declare @TableName varchar(100) = (select Name from @Table where id = @Index);

	if @TableName is null
		break;
	exec('select * from ' + @TableName + ' where Header = ''CM resigns today''');
end

create a table variable, it load table name which have column 'Header'. Iterate the table variable and execute dynamic sql where Header column contain 'CM resigns today'.

Try this as below

SQL

DECLARE @Sql nVarchar(max)
DECLARE @Col Varchar(max)
DECLARE @ST Varchar(max)
DECLARE @Table Varchar(MAX)
DECLARE @Result Varchar(MAX)

SET @Col = 'AccountNumber'
SET @ST = 'AUSTRALI0001'

SELECT TABLE_SCHEMA+'.'+TABLE_NAME as TableName INTO #Temp FROM INFORMATION_SCHEMA.COLUMNS Where COLUMN_NAME = @Col

DECLARE Table_Cur cursor FOR
SELECT TableName FROM #Temp

OPEN Table_Cur
FETCH NEXT FROM Table_Cur INTO @Table

WHILE @@FETCH_STATUS = 0
BEGIN
SET @Sql = 'Select '+@Col+' From '+@Table+' Where '+@Col+' = '''+@ST+''''
exec sp_executesql @Sql, N'@x int out', @Result out

END

CLOSE Table_Cur
DEALLOCATE Table_Cur

Drop TABLE #Temp
