  • SQL query doesn't get inserted

    - by Deejdd
    I've been trying to get my query to work for some time it runs but doesn't insert anything nor does it return any errors. The database connection is open and is successfuly connection. The Table is called errorlog and holds the following data - id (int autoincremental, Primary key, Unique) - exception (varchar) - time (DateTime) exception = String(error message) time = DateTime.Now Here's the code: public void insertError(string error, DateTime time) { SqlCeParameter[] sqlParams = new SqlCeParameter[] { new SqlCeParameter("@exception", error), new SqlCeParameter("@time", time) }; try { cmd = new SqlCeCommand(); cmd.Connection = connection; cmd.CommandType = CommandType.Text; cmd.CommandText = "INSERT INTO errorlog (exception, time) VALUES(@exception, @time)"; cmd.Parameters.AddRange(sqlParams); cmd.ExecuteNonQuery(); } catch (Exception e) { Console.WriteLine(e.Message); } } Any help would be appreciated, Thanks in advance. EDIT Removed quotes around @exception Heres the connection: protected DataController() { try { string appPath = System.IO.Path.GetDirectoryName(Assembly.GetAssembly(typeof(DataController)).CodeBase).Replace(@"file:\", "") + @"\"; string strCon = @"Data Source = " + appPath + @"Data\EasyShop.sdf"; connection = new SqlCeConnection(strCon); } catch (Exception e) { } connection.Open(); } Finally the way it gets called: public bool log(string msg, bool timestamp = true) { DataController dc = DataController.Instance(); dc.insertError(msg, DateTime.Today); return true; }

  • how to integrate my users database table with the aspnet_users table that comes with asp.net members

    - by ooo
    i have a database that already has a users table COLUMNS: userID - int loginName - string First - string Last - string i just installed the asp.net membership table. Right now all of my tables are joined into my users table foreign keyed into the "userId" field How do i integrate asp.net_users table into my schema? here are the ideas i thought of: Add a membership_id field to my users table and on new inserts, include that new field in my users table. This seems like the cleanest way as i dont need to break any existing relationships. break all existing relationship and move all of the fields in my user table into the asp.net_users table. This seems like a pain but ultimately will lead to the most simple, normalized solution any thoughts?

  • How to log SQL output to text file on client from C#

    - by Rob Packwood
    I have a large auditing stored procedure that prints values and runs some SELECT statements. When running within SQL Management Studio we have the use select to display "Results to Text" so all of the SQL results and print statement display in one place. Now I need to have some C# code also call this auditing procedure at the end of the process and basically store all data that would be in the "Results to Text" window into a .txt file. How can this be done?

  • Performance problem on a query.

    - by yapiskan
    Hi, I have a performance problem on a query. First table is a Customer table which has millions records in it. Customer table has a column of email address and some other information about customer. Second table is a CommunicationInfo table which contains just Email addresses. And What I want in here is; how many times the email address in CommunicationInfo table repeats in Customers table. What could be the the most performer query. The basic query that I can explain this situation is; Select ci.Email, count(*) from Customer c left join CommunicationInfo ci on c.Email1 = ci.Email or c.Email2 = ci.Email Group by ci.Email But sure, it takes about 5, 6 minutes in execution. Thanks in Advance.

  • Sorting results by a char(1) column

    - by Brandon
    I have a stored procedure which basically does something like select top 1 expiryDate, flag, (bunch of other columns) from someTable (bunch of joins) order by expiryDate desc So this will grab the record that expires last. This works for most cases, except some records have a flag that are just a char(1). Most of the time it's just Y or N. So it'll return something like 2010-12-31 N 2010-10-05 Y 2010-08-05 N 2010-03-01 F 2010-01-31 N This works, most of the time, but is there any way to order it by the Flag column as well? So I'd want to group the results by Y, then N, and F and any other flags can go last in any order. I thought this would just be an order by, but since the flags are not weighted by the alphabetic value, I'm a little stumped. (Note: These are not my tables, I don't know if using the characters like this was a good idea or not, but it's not something I can change).

  • SP: Random Records, Fave Record, Plus Known Record, NO repetition.

    - by Munklefish
    Hi, Thanks to help from a lot of you guys ive been given the following code which works great. However ive realised ive missed an important bit of info out of the question and so have reposted here (with updated code) to clarify. The following code gets 5 random records from a table plus a further single record based on the users favourite as identified in a second table: CREATE PROCEDURE web.getRandomCharities ( @tmp_ID bigint --members ID ) AS BEGIN WITH q AS ( SELECT TOP 5 * FROM TBL_CHARITIES WHERE cha_Active = 'TRUE' AND cha_Key != '1' ORDER BY NEWID() ) SELECT * FROM q UNION ALL SELECT TOP 1 * FROM ( SELECT * FROM TBL_CHARITIES WHERE TBL_CHARITIES.cha_Key IN ( SELECT members_Favourite FROM TBL_MEMBERS WHERE members_Id = @tmp_ID ) EXCEPT SELECT * FROM q ) tc END However, i realised i also need to include the record where "cha_Key == '1'" if it isnt the same as the record returned in the second SELECT statement in the code shown above. HOpe that makes sense? THANKS!!!

  • how to reuse a CASE in the WHERE ?

    - by Thibault Witzig
    Hello I'm trying to do a request that looks like this SELECT field1, field2, field3 = CASE WHEN field2 = 'something' THEN 'something' WHEN field1 IS NOT NULL and field2 IS NULL THEN 'somethingElse' ELSE NULL END FROM SomeTable WHERE field3 IS NOT NULL This results in a syntax error. I have to rewrite the CASE in the WHERE instead of just refering to it. Is there a better way to achieve this ? And out of curiosity, why is "WHERE field3 IS NOT NULL" refused while for example "ORDER BY field3" would pass ?

  • How to invoke a 64-bit app in a 32-bit process space?

    - by CTVerint
    Hi, in a 64-bit WinOS ennvironment, how can a 32-bit process/app such as CMD invoke a 64-bit app? For example, we have a 32-bit launcher (aka installation program). It needs to invoke a 64-bit 3rd party installer. Presently, doing so will render the OS to say it's not a Win32 App. If you know of any workaround or suggestion, I am all ears... thanks, CT

    I simply want to include a row number against the returned results of my query. I found the following post that describes what I am trying to achieve but gives me an exception http://vaultofthoughts.net/LINQRowNumberColumn.aspx "An expression tree may not contain an assignment operator" In MS SQL I would just use the ROWNUMBER() function, I'm simply looking for the equivalent in LINQ.

  • MS SQL: How to get the newest date in a table with several equal keys

    - by Qohelet
    Unfortunately my knowledge related to statements like "group by" and "having" is quite limited, so hopefully you can help me: I have a view -here's an excerpt- (if we have some Europeans here - it's v021 of Winline/Mesonic): ID | Artikelbezeichnung1 | Bez2 | mesoyear _____________________________________________________________________ 1401MA70 | Marga ,Saracena grigio,1S,33,3/33,3 | Marazzi | 1344 1401MA70 | Marga ,Saracena grigio,1S,33,3/33,3 | Marazzi | 1356 1401MA70 | Marga ,Saracena grigio,1S,33,3/33,3 | Marazzi | 1356 1401MA71 | Marga ,Saracena beige,1S,33,3/33,3 | Marazzi | 1344 1401MA71 | Marga ,Saracena beige,1S,33,3/33,3 | Marazzi | 1356 1401MA71 | Marga ,Saracena beige,1S,33,3/33,3 | Marazzi | 1356 2401CR13 | Crista,Mahon rojo,1S,33,3/33,3 | Cristacer | 1332 2401CR13 | Crista,Mahon rojo,1S,33,3/33,3 | Cristacer | 1344 So the ID is not unique and I just need the one with the highest val in "mesoyear". My fist solution was: Select c015 as ID, c003 as Artikelbezeichnung1, c074 as Bez2, mesoyear from CWLDATEN_91.dbo.v021 group by c015 having mesoyear = max(mesoyear) But this doesn't work at all... Msg 8121, Level 16, State 1, Line 8 Column 'CWLDATEN_91.dbo.v021.mesoyear' is invalid in the HAVING clause because it is not contained in either an aggregate function or the GROUP BY clause. So I just removed the "having" statement and it went "better": Msg 8120, Level 16, State 1, Line 2 Column 'CWLDATEN_91.dbo.v021.c003' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause. So I tried to remove the error just by adding things to the "group by". And it worked. Select c015 as ID, c003 as Artikelbezeichnung1, c074 as Bez2, max(mesoyear) from CWLDATEN_91.dbo.v021 group by c015,c003,c074 gives me exactly what I want. But the correct Select contains about 24 columns and some calculations as well. The problem can't be solved just by adding all the columns to the "group by"...? Can someone please help me to find a proper command? Thank you!

  • SqlCE Flush Interval - Will the default setting lead to corruption?

    - by NormD
    SqlCE has a parameter set on the Connect String called Flush Interval. It is defined as: The interval time (in seconds) before all committed transactions are flushed to disk. If not specified, the default value is 10. I thought that a committed transaction, by definition, is a transaction that has been flushed to disk, specifically the database file. If a transaction is only stored in RAM then cannot the transaction be easily lost? I thought that transactions were first written to a log file and then applied to the database file itself, so perhaps this parameter could mean the time to wait until the transaction log is applied to the database file? I would have thought that this parameter should be 0.

  • Please explain this delete top 100 SQL syntax

    - by Patrick
    Basically I want to do this: delete top( 100 ) from table order by id asc but MS SQL doesn't allow order in this position The common solution seems to be this: DELETE table WHERE id IN(SELECT TOP (100) id FROM table ORDER BY id asc) But I also found this method here: delete table from (select top (100) * from table order by id asc) table which has a much better estimated execution plan (74:26). Unfortunately I don't really understand the syntax, please can some one explain it to me? Always interested in any other methods to achieve the same result as well. EDIT: I'm still not getting it I'm afraid, I want to be able to read the query as I read the first two which are practically English. The above queries to me are: delete the top 100 records from table, with the records ordered by id ascending delete the top 100 records from table where id is anyone of (this lot of ids) delete table from (this lot of records) table I can't change the third one into a logical English sentence... I guess what I'm trying to get at is how does this turn into "delete from table (this lot of records)". The 'from' seems to be in an illogical position and the second mention of 'table' is logically superfluous (to me).
