Question

Is it possible to convert an integer in 4 position varchar.. Example I have the integer 1 and I get varchar ‘0001’, for integer 550 I get varchar ‘0550’ .

Thanks

Answer 1

or this ?

right('000'+ convert(varchar,MyNum),4)

I just did some rough timings on the various methods and this solution seemed to be a little quicker than the others. That surprised me …

DECLARE @loop INT;
DECLARE @MyNum INT;
DECLARE @Upper INT;
DECLARE @Lower INT;
DECLARE @result VARCHAR;
DECLARE @start DATETIME;

SET @Lower = 1;
SET @Upper = 9999;  
SET @loop = 10000;

SET @start = GETDATE();

WHILE @loop > 0 BEGIN
  SELECT @MyNum = ROUND(((@Upper - @Lower -1) * RAND() + @Lower), 0);
  SET @loop = @loop -1;
  SET @result = right('000'+ convert(varchar,@MyNum),4);
  -- SET @result = right(10000 + @MyNum, 4);
  -- SET @result = right(convert(float, @MyNum) / 10000, 4);
  -- SET @result = stuff('0000', 1 + 4 - len(@MyNum), len(@MyNum), @MyNum);
  -- SET @result = replace(str(@MyNum, 4), ' ', '0');   
END;

SELECT GETDATE() - @start;
