How do I find ALL the positions of a certain character in a string?

I am trying to find the positions of all the $ in the summary string.  I'm just doing a simple select and I am getting an error that loc1, loc2, loc3 are invalid columns.  Hellllp!  

SELECT [Case ID], Summary,
charIndex('$',[summary],1) as loc1 ,
charindex('$',[Summary],(loc1 + 1)) as loc2
charindex('S',[Summary],(loc2 + 1)) as loc3
FROM [tblRemedy Tickets]
WHERE Item Like '%User%' AND Summary Like '%$%';

summary = "CTSU$CSBBWWW$WCAROL$"

you are missing a comma after loc2

charindex('$',[Summary],(loc1 + 1)) as loc2 ,

Thanks anyway but

I figured it out.....to find all occurrences, I need to imbed the previous charindex.....For example:

SELECT [Case ID], Summary,
charIndex('$',[summary],1),
charindex('$',[summary],charIndex('$',[summary])+1)
FROM [tblRemedy Tickets]
WHERE Item Like '%User%' AND Summary Like '%$%'

actually, my answer did work either.  I have to find all 8 occurrences using charindex.  When I name the outcome as AS, I still get the invalid column error.  Help anyone?

>> When I name the outcome as AS

not sure what you mean by this -- you want the resulting column to be named "AS" ?

if so, then do this:  as [AS]

... or are you saying you are having trouble aliasing the charindex columns?

SELECT [Case ID], Summary,
charIndex('$',[summary],1) as [loc1],
charindex('$',[summary],charIndex('$',[summary])+1) as [loc2]
FROM [tblRemedy Tickets]
WHERE Item Like '%User%' AND Summary Like '%$%'

yes, when I use the alias for the column names, I get an error that the column name is invalid.

The only way that I know of to get all occurences is to use it in a loop and keep track of all the indexes.

You could do it in a FUNCTION and return a string with index,index,index and it would become a column in your output.

This little snippet should be able to help you run this:

DECLARE @index int
SET @index = -1
DECLARE @return varchar(100)
DECLARE @value varchar(100)
SET @value = 'NaNaNaNaNaNa'
SET @return = ''

WHILE @index > 0 OR @index = -1
  BEGIN
      SELECT @index = CHARINDEX('N', @value, @index+1)
      IF @index > 0
        BEGIN
            SELECT @return = @return + ',' + CAST(@index as varchar)
        END
  END

SELECT SUBSTRING(@return, 2, LEN(@return)-1)

So you would just put this in a function that RETURNS varchar(50) or whatever and RETURN (@return) and the @value should be the one that you pass in.

Say your FUNCTION name is GetIndexesFromValue, then your query would be:

SELECT [Case ID], GetIndexesFromValue(Summary) as Summary,
FROM [tblRemedy Tickets]
WHERE Item Like '%User%' AND Summary Like '%$%'

Hope that helps.
