Hi,
  I have a query like below. I want to get count(*) result into a variable when I execute the sql. Please let me know how can I do it.


SET @sql = '   SELECT count(*), (SELECT name from users where user_no='+CAST(@physicianID AS varchar(10))+') as physicianName,null,null,null,null,null,null,null,null,null,null,NULL,NULL from(
      SELECT
            examdate,
            patient_no
      FROM exams WHERE
          examdate>='''+LEFT(CONVERT(VARCHAR, @startDate, 112), 8)
+''' AND
          examdate<='''+LEFT(CONVERT(VARCHAR, @endDate, 112), 8) + ''''

IF @physicianID > 0
    SET @sql = @sql + ' AND
           requestedby = ' + CAST(@physicianID AS varchar(10))

SET @sql = @sql + '
        GROUP BY examdate,patient_no) AS SourceQuery'
EXEC sp_executesql @sql

DECLARE @ParmDefinition nvarchar(500);
SET @ParmDefinition = N'@ResultOut integer OUTPUT';

declare @result integer
EXEC dbo.sp_executesql @sql, @ParmDefinition, @ResultOut=@result output;

get your count using sp_executesql

declare @yourcount int
SET @sql = 'Declare @totcount int  SET @totcount=SELECT count(*), (SELECT name from users where user_no='+CAST(@physicianID AS varchar(10))+') as physicianName,null,null,null,null,null,null,null,null,null,null,NULL,NULL from(
      SELECT
            examdate,
            patient_no
      FROM exams WHERE
          examdate>='''+LEFT(CONVERT(VARCHAR, @startDate, 112), 8)
+''' AND
          examdate<='''+LEFT(CONVERT(VARCHAR, @endDate, 112), 8) + ''''

IF @physicianID > 0
    SET @sql = @sql + ' AND
           requestedby = ' + CAST(@physicianID AS varchar(10))

SET @sql = @sql + '
        GROUP BY examdate,patient_no) AS SourceQuery'
EXEC sp_executesql @sql,'totcount int OUTPUT',@yourcount output
