SQLRowCount() Returning -1 When Used With SELECT Statement.
Nov 13, 2007
Hi friends,
I am facing problem with SQLRowCount() function which is returning -1 when I tried to fetch records greater than 99 from my data file. if the data file contains total of 99 records then the above function is returning its second parameter value nRowCount as 99 but if dat file contains 100 records then it is returning nRowCount as -1
Please tell me whether it is a driver specic error or some thing else. I am using a ODBC driver for a database called MYOB.
Below is the piece of code that I used for fetching records.
if (SQLExecDirect(m_StmtHandle, (PUCHAR)sExecuteStatement.c_str(), SQL_NTS) != SQL_SUCCESS) return false;
if (SQLNumResultCols(m_StmtHandle,(SQLSMALLINT *) &nColumnCount) != SQL_SUCCESS) return false;
if (SQLRowCount(m_StmtHandle,&nRowCount) != SQL_SUCCESS) return false;
The string 'sExecuteStatement' in SQLExecDirect() function above is carrying a Select query.
Its an unpredictable error because the function fails to return exact row count for 100 records, but it is working fine with 99 records.
I am not using any kind of array with size of 99 or 100 in my code.
What I want to know is:
1. Can I use SQLRowCount() with SELECT statement, If not what is the alternative.
2. Is this a driver specific error?.
3. Can I use SQL_DIAG_ROW_COUNT instead of SQLRowCount? If Yes, How to use it?.
Your help will be greatly appriciated if you give me a piece of code for this issue.

All- Please assist: In this SELECT statement: 1 SELECT person_id, (last + ', ' + first + ' on ' + CASE f.address_1 WHEN NULL THEN 'none' ELSE f.address_1 END) as last_first_address 2 FROM person 3 4 LEFT JOIN family f 5 ON person.family_id = f.family_id
I'm finding that the compound column last_first_address returns <null> when f.address_1 is null, even though it seems like it should return the string "none" per my CASE statement. If f.address_1 is not NULL, then it the statement works as expected. Please advise as to how I can fix the statement so that "none" is returned as the final string in last_fist_address if f.address_1 is null. Note: I tried removing the parens. No effect on result. Thanks! -Kurt
I am writing a query and have the bulk of it already written.
I am looking at a table that contains customer orders. There is a column named Customer_Order.Status Available values for this column is R, F, H, and C.
I'd like for my query to return all lines that have the value R, F, H.
My where clause is written like this
WHERE CUSTOMER_ORDER.SITE_ID = 'XXX' AND CUSTOMER_ORDER.STATUS = ('R','H','F')
Here's my statement below. What I'm trying to get is joining the name column in master.sys.databases with a sub query for the database name, file location and backup start date from the MSDB database. The reason for this, if a new database has never been backed up, It should be returning as a NULL value, which is my goal. However, I'm getting multiple results for the backups.
select CONVERT(CHAR(100), SERVERPROPERTY('Servername')) AS Server,a.name,File_Location=b.physical_device_name,backup_start_date=max(backup_start_date) from master.sys.databases a left join(select c.database_name,backup_start_date=max(backup_start_date),b.physical_device_name from msdb.dbo.backupmediafamily b join msdb.dbo.backupset c on c.media_set_id=c.backup_set_id where c.type='D'
I have a table which is returning inconsistent results when I queryit!In query analyzer:If I do "SELECT * FROM TABLE_NAME" I get no rows returned.If I do "SELECT COL1, COL2 FROM TABLE_NAME" I get 4 rows returned.In Enterprise manager:If I do "return all rows" I get 4 rows returned, and the SQL is listedas being "SELECT * FROM dbo.TABLE_NAME".I've tried adding the "dbo." before my table name in QA, but it seemsto make no difference.I'm using SQL Server 2000, which is apparently 8.00534.Can anyone help me, or give me ideas about what to check?Thanks,Rowland.
I have an SQL statement to find attractions between certain longitude and latitude values. The attraction i have already added to the database to test has values 51.502899 and 0.003552 for latitude and longitude. As you can see these values fall within the limits of the statement below but nothing is returned.
SELECT * FROM Attractions WHERE (Lat BETWEEN 51.51998 AND 51.49999) AND (Long BETWEEN 0.014 AND -0.006);
Hi, I have three tables: 1 Order Details 2 Product Info 3 Received Qty
The query is pretty simple however I'm getting incorrect results.
The query grabs a load of information (including a SUM statement) from the order details tbl.. this is INNER JOIN ed to the products tbl to match an ID field which grabs some extra info from the product info tbl.
all fairly straightforward and works without a problem..
However I now need to add in the received qty tbl (as the name suggests this keep a track of the qty's of items received)
I need to join this tbl to the order details tbl based on a unique ID from the orders tbl and then SUM together all of the entries in that received qty tbl for that item.
Result is I get a single record which shows the qty ordered (from the order details tbl), and the total received (from the received qty) tbl
These are held in a seperate tbl as an order can be deliveryed in several stages.
Here is my statement:
SELECT PDS_Login.Supplier_Products.ProductName, PDS_Login.Supplier_Products.ProductCode, dbo.Suppliers_POs_Details.POID, dbo.Suppliers_POs_Details.PODetailsID, dbo.Suppliers_POs_Details.Qty, dbo.Suppliers_POs_Details.PricePerItem, dbo.Suppliers_POs_Details.PoDetailsStatus, dbo.Suppliers_POs_Details.PoDateExpected, dbo.Suppliers_POs_Details.PODateReceived, SUM(dbo.Suppliers_POs_Details.Qty * dbo.Suppliers_POs_Details.PricePerItem) AS LineTotal, SUM(dbo.Suppliers_POs_Details_Received.Qty) AS QtyReceived FROM dbo.Suppliers_POs_Details INNER JOIN PDS_Login.Supplier_Products ON dbo.Suppliers_POs_Details.ProductID = PDS_Login.Supplier_Products.ProductID LEFT OUTER JOIN dbo.Suppliers_POs_Details_Received ON dbo.Suppliers_POs_Details.PODetailsID = dbo.Suppliers_POs_Details_Received.PODetailsID WHERE (dbo.Suppliers_POs_Details.POID = @POID) GROUP BY dbo.Suppliers_POs_Details_Received.Qty, PDS_Login.Supplier_Products.ProductName, PDS_Login.Supplier_Products.ProductCode, dbo.Suppliers_POs_Details.POID, dbo.Suppliers_POs_Details.PODetailsID, dbo.Suppliers_POs_Details.Qty, dbo.Suppliers_POs_Details.PricePerItem, dbo.Suppliers_POs_Details.PoDetailsStatus, dbo.Suppliers_POs_Details.PoDateExpected, dbo.Suppliers_POs_Details.PODateReceived, dbo.Suppliers_POs_Details_Received.Qty
The problem is, if there is more than one relating record in teh Received Qty tbl instead of that being added together as I want, two results appear...
It's obviously something simple but I can't seem to figure it out - anyone point me in the right direction?
I have a query that pulls a list of organizations. I'm trying to use a CASE statement to add a column of names based on the relationship of the individual to that organization. It is possible for two people at the organization to both have that relationship to the organization. Currently, when I pull my results, I get all the individual's names for all the organizations, but I'm also getting a row where there is no name, something like:
Some of the organizations, they have no one with the relationship, but for all the organizations that do have someone in the position I want to not see the blank row. My case statement is:
CASE WHEN EXISTS (Select ind_customer.cst_key WHERE ixo_rlt_code = 'Relationship' ) THEN ind_customer.cst_ind_full_name_dn ELSE '' END AS 'FULL NAME'

Hi, My Select query returing the one column: Options 1 2 3 Form this Options column I have to check the Checkbox1, checkbox2, checkbox3 out of total 6 checkboxes in asp.net form. I am getting the Options column from database. How to store that resultset. Thanks in advance.
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian
Hi there ; This Problem is goin to make me crazy! I've got a table with couple of fields, 2 of them are DateTime, in Sql Express 05 . I used asp.net 2.0 to insert datetime values, directly, using sth like DateTime.Now.ToString() . i use 2 selects as follows : 1)select * from X where Date1='8/9/2006 11:17:41 AM' 2)select * from X where Date2='8/9/2006 11:17:41 AM' #1 is OK, but the second one returns a row with all columns set to NULL . (X is the name of the table) Thanks in advance
I have a UDF with a select * that works fine in one region (DEV) but not another (QC). It's not returning the last 2 columns from the table in QC.I looked at the UDF and it does a fairly simple select:
select a.* from myTable A
The table is the same in both regions and I did a sp_help on the table to ensure these 2 columns are listed. They are. Also, executing a select * in a query windows does return the final 2 columns from the table in QC. The issue resides in the QC version of the UDF only.
The UDF has already been updated to retrieve all columns by name but I'm curious why this would happen. For some reason I'd just like to know and in case it happens again.
I have a strange situation with an select. I've noticed that when I select top 100, a record is not returning from the database, but when doing top 101 the record appears on position 41.
The query is like this:
select top 100 GroupId, count(HouseId) from House h group by h.GroupId order by max([DateCreated]) desc
From all discussions about top 100 vs top 101 I've noticed that everybody is saying that top 101 is using another algorithm and we can have a speed problem, but my problem is not about this. With top 100 I'm missing a record that should appear at index 41.
I am using a SQLDataSource with the following Select query. If the "spouse" values are not in the database, I get the HTML non-breaking-space character back, rather than an empty string.
SelectCommand="select applicant_id, (applicant_last_name + ', ' + applicant_first_name) as applicant_name, CONVERT(varchar(10), applicant_dob, 101) as applicant_dob, applicant_ssn, (spouse_last + ', ' + spouse_first) as spouse_name, CONVERT(varchar(10), spouse_dob, 101) as spouse_dob, spouse_ssn from applicant where applicant_last_name like '%'+@last_name+'%' order by applicant_last_name"
Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.
hiI need to write a stored procedure that takes input parameters,andaccording to these parameters the retrieved fields in a selectstatement are chosen.what i need to know is how to make the fields of the select statementconditional,taking in consideration that it is more than one fieldaddedfor exampleSQLStmt="select"if param1 thenSQLStmt=SQLStmt+ field1end ifif param2 thenSQLStmt=SQLStmt+ field2end if
Code Block SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02' FROM myTables WHERE Conditions are true ORDER BY Field01
The results are just as I need:
Field01 Field02
------------- ----------------------
192473 8461760
192474 22810
Because other reasons. I need to modify that query to:
Code Block SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02' INTO AuxiliaryTable FROM myTables WHERE Conditions are true ORDER BY Field01 SELECT DISTINCT [Field02] FROM AuxTable The the results are:
Field02
----------------------
22810 8461760
And what I need is (without showing any other field):
Field02
----------------------
8461760 22810
Is there any good suggestion? Thanks in advance for any help, Aldo.
Hi, Hope you guys won't mind this rather newbie question. I'm writing a simple blog page for my website and have created a SqlDataSource which queries the database for a list of blog post titles (from the web.Blog table) and the number of comments (from the web.BlogComments table). The SqlDataSource control is: <asp:SqlDataSource ID="sourceBlogArticles" ProviderName="System.Data.SqlClient" connectionString="<%$ ConnectionStrings:myDatabase %>" runat="server" SelectCommand="SELECT gb.blogID, gb.title, gb.description, gb.tags, gb.dateAdded, COUNT(gbc.blogID) AS noOfComments FROM web.Blog gb LEFT OUTER JOIN web.BlogComments gbc ON gb.blogID = gbc.blogID GROUP BY gb.blogID, gb.title, gb.description, gb.tags, gb.dateAdded ORDER BY gb.dateAdded"></asp:SqlDataSource> This works perfectly well if each blog entry in the web.Blog table has associated comments in the web.BlogComments table. However, if there are no comments yet defined in the web.BlogComments table for that blogID then no row is returned in ASP.Net (as checked with a GridView control or similar linked to the data source to view what I get) HOWEVER, I think the SELECT command IS correct: if I use the select command as a query in SQL Server Managment Studio Express, I do get the rows returned, with 0 for the number of comments which is what I would expect for that query: blogID, title, description, tags, dateAdded, noOfComments 1, title 1, description for title 1, tag1, 2007-09-27 06:49:03.810, 32, title 2, description for title 2, tag2, 2007-09-27 06:49:37.513, 03, title 3, description for title3, tag3, 2007-10-02 18:21:30.467, 0 Can anyone help? The result from the SSMSE query is what I want, yet when I use the very same SELECT statement in my SqlDataSource I don't get any rows returned if the BlogComment count is zero (in the above example I get only the first row). Many thanks for any suggestions!
SQL 2005 9.00.3402.00 (x64) As Above really when I select * OR select a single column from the view the wrong column data is returned. in SQL Management Studio when I expand the Columns of the view it reflects the old table structure not the new table structure. I can easily fix by compiling the view again but this would mean I would have to recompile all referencing views when I make a change to table structures. I've tried various DBCC Clean Buffers & drop cache with no effect. Is there a command to recompile all views & poss stored procs in a database. Any help or explanation would be appreciated GW
HiI'm not sure what the best approach for this is:I have a stored procedure which I would like to use to return severaloutput values instead of returning a recordset.CREATE PROCEDURE Test (@param1 int, @param2 int OUTPUT, @param3 intOUTPUT) ASSELECT field2, field3 FROM Table WHERE field1 = @param1I would like to return @param2 as field2 and @param3 as field3How do I do this without using SELECT multiple times?THanks in advanceSam
I have a script with a number of different Left Joins. When I run it in Query Analyzer the Left Join works as a normal join and suppresses some rows. However when the same code is used in a stored procedure the correct results are produced when the stored procedure is executed. Can anyone tell me what is causing this?

Hey Guys. I’m having a little trouble and was wondering if you could help me out. I’m trying to create a custom paging control, so I create a stored procedure that returns the appropriate records as well as the total amount of records. And that works fine. What I’m having problems with is reading the data from the second select statement within the code. Anyone have any idea on how to do this? Also.. how can I check how many tables were returned? Here's my code. I'm trying to keep it very generic so I can send it any sql statement:public DataTable connect(string sql) { DataTable dt = new DataTable();
SqlConnection SqlCon = new System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings["MyDB"].ToString()); SqlDataAdapter SqlCmd = new SqlDataAdapter(sql, SqlCon); System.Data.DataSet ds = new System.Data.DataSet(); SqlCmd.Fill(ds);
dt = ds.Tables[0];
//Here's where I don't know how to access the second select statement
return dt; } Here's my stored procedure: ALTER PROCEDURE dbo.MyStoredProcedure ( @Page int, @AmountPerPage int, @TotalRecords int output )
AS
WITH MyTable AS (
Select *, ROW_NUMBER() OVER(ORDER BY ID Desc) as RowNum From Table where Deleted <> 1 )
select * from MyTable WHERE RowNum > (((@Page-1)*@AmountPerPage)) and RowNum < ((@Page*@AmountPerPage)+1);
Select @TotalRecords = COUNT(*) from Table where Deleted <> 1 RETURN
