I am trying to print a selected value, is this possible?
Example:
PRINT
SELECT SUM(Amount) FROM Expense
This question is related to
sql-server
tsql
select-query
The answer is
If you want to print more than a single result, just select rows into a temporary table, then select from that temp table into a buffer, then print the buffer:
drop table if exists #temp
-- we just want to see our rows, not how many were inserted
set nocount on
select * into #temp from MyTable
-- note: SSMS will only show 8000 chars
declare @buffer varchar(MAX) = ''
select @buffer = @buffer + Col1 + ' ' + Col2 + CHAR(10) from #temp
print @buffer
Try this query
DECLARE @PrintVarchar nvarchar(max) = (Select Sum(Amount) From Expense)
PRINT 'Varchar format =' + @PrintVarchar
DECLARE @PrintInt int = (Select Sum(Amount) From Expense)
PRINT @PrintInt
set @n = (select sum(Amount) from Expense)
print 'n=' + @n
You can also use the undocumented sp_MSforeachtable stored procedure as such if you are looking to do this for every table:
sp_MSforeachtable @command1 ="PRINT 'TABLE NAME: ' + '?' DECLARE @RowCount INT SET @RowCount = (SELECT COUNT(*) FROM ?) PRINT @RowCount"
If you wish (like me) to have results containing mulitple rows of various SELECT queries "labelled" and can't manage this within the constraints of the PRINT statement in concert with the Messages tab you could turn it around and simply add messages to the Results tab per the below:
SELECT 'Results from scenario 1'
SELECT
*
FROM tblSample
If you're OK with viewing it as XML:
DECLARE @xmltmp xml = (SELECT * FROM table FOR XML AUTO)
PRINT CONVERT(NVARCHAR(MAX), @xmltmp)
While the OP's question as asked doesn't necessarily require this, it's useful if you got here looking to print multiple rows/columns (within reason).
I wrote this SP to do just what you want, however, you need to use dynamic sql.
This worked for me on SQL Server 2008 R2

Example:
exec [dbo].[PrintSQLResults] n'select * from MyTable'
If you want to print multiple rows, you can iterate through the result by using a cursor. e.g. print all names from sys.database_principals
DECLARE @name nvarchar(128)
DECLARE cur CURSOR FOR
SELECT name FROM sys.database_principals
OPEN cur
FETCH NEXT FROM cur INTO @name;
WHILE @@FETCH_STATUS = 0
BEGIN
PRINT @name
FETCH NEXT FROM cur INTO @name;
END
CLOSE cur;
DEALLOCATE cur;
Add
PRINT 'Hardcoded table name -' + CAST(@@RowCount as varchar(10))
immediately after the query.
