Hello,
i use mysql 4.0.20 and have the following problem:
I have a column with names and want to extract all names which are lets say 3 times in this column. See
Names
foo
bar
bla
foo
bla
bla
foo
In this case mysql shoud output foo and bla, but how to do this??
I tried some combinations of count and something like subselects, but no success.
Could anybody help me please? It drives me crazy.
Thanks, b52
Hello @community,
I have a special problem.
I use under MS SQL 2005 a user-function which i use to check rights in my system . This function is used in a subselect in my queries.
Using MS SQL 2000 I have problems with this. The function itself works fine. It also works in the subselect if I use constant parameters for @matchids
If I user a column from the main select I get an error message. Server: Nachr.-Nr. 170, Schweregrad 15, Status 1, Zeile 7.
Here is my function:
CREATE FUNCTION sf_MatchRights
(
@uid int = 0,
@matchids varchar(4000) = '',
@delimiter char(1) = ','
)
RETURNS @results TABLE ( returncode int )
AS
BEGIN
INSERT INTO @results VALUES (2)
DECLARE @value int
DECLARE cur CURSOR LOCAL FOR
SELECT [value] FROM fn_Split (@matchids,@delimiter)
OPEN cur
FETCH FROM cur INTO @value
WHILE @@FETCH_STATUS = 0
BEGIN
IF ( @value = @uid ) UPDATE @results SET returncode = 1
IF ( @value < 0 )
BEGIN
IF (SELECT COUNT(*) AS Counter FROM krgroupusers WHERE luserid=@uid AND lgroupid=(@value*-1))>0 UPDATE @results SET returncode = 1
END
FETCH NEXT FROM cur INTO @value
END
CLOSE cur
DEALLOCATE cur
RETURN
END
And here my select:
SELECT lid, dtcreation AS xTime, dtedit AS xActivity, xstitle AS xTitle, xtcomment AS xDesc, lcreatorid AS xUid, 10024 AS xAppid
FROM xinnovator
WHERE xinnovator.xlcontact=@contact
AND (lcreatorid=@uid
OR (xlcategory IN (SELECT lid FROM xinnovatorcats WHERE (SELECT returncode FROM sf_MatchRights (@uid, xinnovatorcats.xtqkmembers,','))=1))
)
If I replace xinnovatorcats.xtqkmembers with e.g. '1|2|3', then it works.
I know I can use columns from main selects in the subselect, too. But it seems I make something wrong with the syntax in sql2000 which works fine under sql2005.
I am thankful for any help.
PS: Here is the split function I use inside die MatchRights function... made it once. Dont run this with tons of rows .
CREATE FUNCTION fn_Split(@text nvarchar(4000), @delimiter char(1) = ',')
RETURNS @Strings TABLE
(
position int IDENTITY PRIMARY KEY,
value nvarchar(4000)
)
AS
BEGIN
DECLARE @index int
SET @index = -1
WHILE (LEN(@text) > 0)
BEGIN
SET @index = CHARINDEX(@delimiter , @text)
IF (@index = 0) AND (LEN(@text) > 0)
BEGIN
INSERT INTO @Strings VALUES (@text)
BREAK
END
IF (@index > 1)
BEGIN
INSERT INTO @Strings VALUES (LEFT(@text, @index - 1))
SET @text = RIGHT(@text, (LEN(@text) - @index))
END
ELSE
SET @text = RIGHT(@text, (LEN(@text) - @index))
END
RETURN
END
I'm trying to get a UNION of UserIDs from multiple subselects. Theoriginal query--which puts all the found UserIDs into separatecolumns, looks like this:--------------------------------------------------------------------------------SELECTtmp_MY_TABLE_2_3_4.LAST_UPDATED_USER_ID AS UserID_1MY_DB_1.MY_TABLE_5.LAST_UPDATED_USER_ID AS UserID_2MY_DB_1.MY_TABLE_6.LAST_UPDATED_USER_ID AS UserID_3FROM(SELECT MY_DB_1.MY_TABLE_1.PRIMARY_KEY_IDFROM MY_DB_1.MY_TABLE_1WHERE MY_DB_1.MY_TABLE_1.PRIMARY_KEY_ID = 12345) AS tmpMY_TABLE_1LEFT JOIN(SELECT MY_DB_2.MY_TABLE_2.PRIMARY_KEY_ID, MY_DB_2.MY_TABLE_2.LAST_UPDATED_USER_IDFROM MY_DB_2.MY_TABLE_2UNIONSELECT MY_DB_2.MY_TABLE_3.PRIMARY_KEY_ID, MY_DB_2.MY_TABLE_3.LAST_UPDATED_USER_IDFROM MY_DB_2.MY_TABLE_3UNIONSELECT MY_DB_2.MY_TABLE_4.PRIMARY_KEY_ID, MY_DB_2.MY_TABLE_4.LAST_UPDATED_USER_IDFROM MY_DB_2.MY_TABLE_4) AS tmp_MY_TABLE_2_3_4ON tmpMY_TABLE_1.PRIMARY_KEY_ID = tmp_MY_TABLE_2_3_4.PRIMARY_KEY_IDLEFT JOINMY_DB_1.MY_TABLE_5 ON tmpMY_TABLE_1.PRIMARY_KEY_ID =MY_TABLE_5.PRIMARY_KEY_IDLEFT JOINMY_DB_1.MY_TABLE_6 ON tmpMY_TABLE_1.PRIMARY_KEY_ID =MY_TABLE_6.PRIMARY_KEY_ID--------------------------------------------------------------------------------As you can see, I'm getting "LAST_UPDATED_USER_ID" from all tables/aliases--but those tables/aliases need to LEFT JOIN to"tmpMY_TABLE_1.PRIMARY_KEY_ID", because I only care about"LAST_UPDATED_USER_ID"'s that are related to my "tmpMY_TABLE_1"records.I tried putting, parenthesis around the whole SQL (aliasing as"tmpAllTables") and putting in the front:--------------------------------------------------------------------------------SELECT tmpAllTables.UserID_1 AS UserID FROM tmpAllTablesUNIONSELECT tmpAllTables.UserID_2 AS UserID FROM tmpAllTablesUNIONSELECT tmpAllTables.UserID_3 AS UserID FROM tmpAllTables--------------------------------------------------------------------------------But that didn't work. Any thoughts?

I have an sql command for when you add a new name to the database it counts to see how many of the name entered to the textbox exist in the database. If the count is 0 then it will add the name to the table. Else it displays an error message.
This works fine for inserting a new name but on my update page where you may update the name I have the same code which on button click counts to see how many exist. But if you leave the textbox the same value and click the button the count obviously results in 1 and brings up an error message.
Is there a way I can do a count but not including the name that is currently the value of the textbox?protected void UpdateSharedArea(object sender, EventArgs e)
{
SqlConnection connection = new SqlConnection(docShare_ConString);
//Count the amount of area names that are the same as typed by user
SqlCommand existCheck = new SqlCommand("SELECT COUNT(doc_area_name) FROM document_area WHERE doc_area_name = @doc_area_name", connection);
SqlParameter areaname = new SqlParameter("@doc_area_name", SqlDbType.VarChar);
areaname.Value = AreaText.Text;
existCheck.Parameters.Add(areaname);
connection.Open();
int count = (int)existCheck.ExecuteScalar();
connection.Close();
//If the area name does not exist within the table
if (count == 0)
{
//Update name Cheers, Mark

I have to create a statement that will find the next highest number of a field that is stored as a char(5), like
' 2' and add a new record adding one to that max number. The field is padded with leading spaces. I know how to get the next number. The question is counting how many spaces I need (is it a 9 or a 10) and then stuffing the leading spaces in front of the new number.
I want to be able to tell how many rows of data I have in each table. I don't want all of the tables detail though. How do I do this?
Thanks,

Hi,
I manage an affiliate tracking database for some of our online advertising campaigns. In the database I have a "clicks" table, and a "Leads" table. I am trying to join these two tables on a "Source" fields then use "group by" so that I can return "Source" counts for both the clicks and leads. I want both counts to show up in the same row such that if I have 100 clicks and 10 leads for source "xyz" the results would be:
source Clicks Leads
xyz 100 10
I have tried the followign query, but it returns the same value for both rows:
SELECT Leads.source, COUNT(Clicks.source),COUNT(leads.source)
FROM Leads INNER JOIN
Clicks ON Leads.source = Clicks.source
GROUP BY leads.source
I can do this with a subquery or by looping through through a recordset, but was wondering if it is possible to do without using these methods.
Does anyone have any ideas? If so I would greatly appreciate your feedback.
Thanks!
Hi,
I've got a database with two tables:
members
notes
Each member can have zero or more notes associated with them and each note has a 'new' field which indicates that it hasn't been read since it was added.
I want to produce a list of members and highlight the ones in bold that have unread notes.
If I use
SELECT members.firstname, COUNT(*) FROM members, notes WHERE notes.member=members.ref AND notes.new=1
then I only get the items that have unread notes (and I don't actually need to know the count).
How can I get what I want?
I am having trouble getting an accurate count for my query. i have
select count(ID) as Cnt from Users
