Parameterized Query That Counts The Number Of Null Values In An Int32 Column
Jul 18, 2006
Using c# in the compact framework, is there a way to do a parameterized query for counting the number of records where a specified column is null. I tried all of these, but none of them work:
cmd.Add(new SqlCeParameter("@IntColumn", SqlInt32.Null));
cmd.CommandText = "select count(*) from TableName where IntColumn is not @IntColumn";
cmd.CommandText = "select count(*) from TableName where not IntColumn = @IntColumn";
cmd.Parameters.Add(new SqlCeParameter("@IntColumn", SqlDbType.Int32));
cmd.Parameters["@IntColumn"].Value = SqlInt32.Null;
cmdGetNumRead.CommandText = "select count(*) from TableName where IntColumn is not @IntColumn";
If txtLink1 happens to be empty, I want @link1 to enter null. The column in the Sql Server allows for nulls, but I get an error message that says no value was supplied. In short, how do I supply a null value using a parameterized query?
#2: For debugging purposes, how can I view what my SQL string looks like (with all the values entered) before it gets submitted to the database? When I view the string, it still contains the placeholder values (@link1) instead of the actual values.
I am hoping someone could help me understand why this is happening and perhaps a solution. I am using ASP.NET 2.0 with a SQL 2005 database. In code behind, I am performing a query using a parameter as below: sql = "SELECT field_name FROM myTable WHERE (field_name = @P1)" objCommand.Parameters.Add(New SqlParameter("@P1", TextBox1.Text)) The parameter is obtained from TextBox1 which has valid input. However, the value is not in the table. The query should not return ANY results. However, I am getting one single row back with null values for each field requested in the query. The SQL user account for this query has select, insert, and update permissions on the table. The query is simple, no joins, and the table has no null values in any fields. If I perform the exact same query using an account with select only permission on the table, I get what I was expecting, no records. Then if I go back to the previous user account with more permissioins, and I change the query to pass the paramter this way: sql = String.Format("SELECT field_name FROM myTable WHERE (field_name = {0})", TextBox1.Text) I also get NO records retuned using the same criteria. What is going on here? I would prefer to use the parameterized query method with the account having elevated permissions. Is there some command object setting that can prevent the null row from returning? Thanks!
I have an SSIS package that imports data from an Excel file, replaces any value in Excel that reads "NULL" to "", then writes the data to a couple of databases.
What I have discovered today, is I have two columns of dates, an admit date and discharge date column, and what I need to do is anywhere I have a null value in the discharge date column, I have to replace it with the value in the admit date column.
I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.
On my company site, I have created a database that is for the purpose of tracking google adwords, as well as pages that the user visits. For instance, if you were to search for "guitars" and then click our ad, an entry is created in the database like thisKeyword: SessionGUID: PageVisited: VisitedDateTime:Guitars lkjfeilfjskdlfjsije ~ViewCategory.aspx?Cat=Guitars,KW=Guitars 12/01/2000 12:00amGuitars lkjfeilfjskdlfjsije ~ViewProduct.aspx?ProductID=1253&SubProductID=3 12/01/2000 12:03amGuitars lkjfeilfjskdlfjsije ~Search.aspx?Q=BC%20%Rich 12/01/2000 12:05am Pretty much, in our administrative area, I want to be able to have a table that would generate these results: Keyword Total HitsGuitars 3So im guessing that obviously I would need to do a select distinct for the Keyword column, but how do I also have a column showing a count of the records?
I have written a function as below to pass some value and get aNOTHER VALUE DURING THE RUNTIME ----------------------------------------------- Sub ExpiaryDate(ByVal Expr1 As String, ByVal Expr2 As String)
Dim strSQLDDL As String = "SELECT STATMENT "
Dim SQlCommand As New SQlCommand(strSQLDDL, mySqlConnection) SQlCommand.CommandType = CommandType.Text
Dim Colleague_CN As String = Int32.Parse(Expr1) Dim Course_ID As String = Int32.Parse(Expr2)
Dim parameterEventType_ID As SqlParameter = _ New SqlParameter("@Colleague_CN", SqlDbType.NVarChar, 50) parameterEventType_ID.Value = Colleague_CN SQlCommand.Parameters.Add(parameterEventType_ID)
Dim parameterCourse_ID As SqlParameter = _ New SqlParameter("@Course_ID", SqlDbType.NVarChar, 50) parameterCourse_ID.Value = Course_ID SQlCommand.Parameters.Add(parameterCourse_ID)
Dim myDataAdapter As SqlDataAdapter = New _ SqlDataAdapter(SQlCommand) myDataAdapter.Fill(DivisionDataSet, "ExpiaryDate") myDataAdapter.Update(DivisionDataSet, "ExpiaryDate") DivisionDataSet.AcceptChanges()
End Sub
Everything was fine as far as i am passing an integer. Now i need to pass a combination of numbers and letters( NVarChar)
HOW DO I GETAROUND THIS PROBLEM WHEN I USE THIS FUNCTION I GET ERRORS SOMETHING LIKE..... Input string was not in a correct format. INDICATES --Dim Colleague_CN As String = Int32.Parse(Expr1.ToString) AS AN ERROR
CAN ANYBODY PLEASE HELP HOW DO I PASS A NVarChar instead THANKS
I have SQL Server 2012 SSIS. I have Excel source and OLE DB Destination.I have problem with importing CustomerSales column.CustomerSales values like 1000.00,2000.10,3000.30,NotAvailable.So I have decimal values and nvarchar mixed in on Excel column. This is requirement for solution.However SSIS reads only numeric values correctly and nvarchar values are set as Null. Why?
Ok I have upgraded my works database from a poorly designed Access database to a SQL database. The previous system allowed NULL values and duplicates to be inserted into a field that should NOT ALLOW NULL Values or duplicates. Therefore, this issue has now been moved across to my new system as I cannot set these constraints on the field that has multiple NULL values.
My solution would be to use a sequential operator, so whatever = NULL would be changed to a sequential number that us as administrators would know was a bogus number starting at something like = 999999900 counting up from that. There are only 250 records that would require updating.
To make things more interesting this field is not a integer type, its a Nvarchar type as its a Hardware ID. Both numerical and characters are require.
I need to list all students who have both parents phone number is null. The parent relationship values 1 and 2 indicates the person is either Mom (value 2) or dad (value 1) of the student. Note: I am using student parent as an example to write my query.
I use a Flat File Connection Manager for a file with 18 columns.
My column delimiter is the "~" caracter and my row delimiter is "{CR}{LF}"
The source files contains about 2300 lines. None of them contain NULL values.
My last row is a numeric(16,2). Even if it is not the appropriate type for the value I want extract, it works with all my columns.
My problem is with the last column. I have read the SQL Server 2005 interpretation of the row delimiter as actually the last row column delimiter.
But, here, my values are OK and put in the destination table if it is not 0 : "+0000000001352" for example in the file.
If it is 0 : "+00000000000000", and if I considered errors as INGORE FAILURE and put data in the destination table, accepting NULL values, I have NULL values in table for these 0 values. And correct values for non-0 values.
How do you explain that ? How I can fix the problem and correctly read my file ?
For your information, if I REDIRECT ROW in the Flat File Error Output, the ErrorCode is : -1071607676 and ErrorDescription is "The data value cannot be converted for reasons other than sign mismatch or data overflow."

I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?

I have such a problem. Need to add additional column to my query. The column should consist of set of fixed number (same as number of query rows) values (text). At start thought it's simple but now Im lost. Is there any chance to do it. Apreciate any help. I need to tell that I have only access to select on this database so no use of operation on tables.
I am trying to have a query with the option for items to be null. (So users don't need to fill in the other fields if they choose not too) SELECT Tickets.TicketID, Tickets.UserID, Tickets.SystemID, Tickets.Title, Tickets.Description, Tickets.Software, Tickets.Date, Systems.OS, OS.OS AS OstitleFROM Tickets INNER JOIN Systems ON Tickets.SystemID = Systems.SystemID INNER JOIN OS ON Systems.OS = OS.osIDWHERE (Tickets.Title LIKE '%' + @title + '%') AND (Tickets.Software LIKE '%' + @software + '%') AND (Tickets.Description LIKE '%' + @descrip + '%') AND (Systems.OS = @osid) OR (@osid IS NULL)This works when i give the LIKE values % as a parameter. So they can choose to search by title + software but not description or description and nothing else etc etc etc. The problem is, the osid. If I give it a value it works but if i try to do null, *. or % it always displays every item in the databse ignoring any of the previous like statements. Anyone have an idea?
I have a grid with checkbox, where users can select multiple rows and edit at the same time and save it to the DB. Now I have used a Footer Template with textbox in the gridview. So if I want to put similar data's for some particular rows at the same time in the grid, I select the multiple rows and try to put values in the footer template textbox and when I click on save, it saves successfully.
UPDATE QUERY: "UPDATE [Test] SET [Name]='" + Name + "',[Designation]= '" + Designation + "', [City]= '" + City + "' WHERE EmpID='" + EmpID + "'";
Now here is the challenge, but even when I enter null values in the footer template textbox it has to save with the old values of the rows and not null values. I tried it and couldn't make it happen. So anything like putting the case for each column and mentioning like if null accept the old value and not null accept new value.
I'm using the query wizard in VB.net to write a query for SQL CE. I want to replace null values with text. I expected the COALESCE function to do this but I get an error message saying its not a valid function. This is a sample.
Select COALESCE(table.Name,'No Name') as Name from table
I have a table names Alert_Event and a new column named BSP_Phone has been added to the table. I am trying to set NULL values to the column and I get the below error. I am setting null values in the bolded text in the query.

Table2 has three columns (i.e. Date, Count and Rule Type). Column “Rule Type “has a default value which is “XYZ”..Now I want to insert Data from Table1 to Table2. I am using following query:-
Column name or number of supplied values does not match table definition.I am using SQL 2012. I understand Table1 has 2 Columns but Table2 has 3 Columns. Is there anyway, I can move data from source table to Destination table where Destination Table has more number of Columns?
I would like to populate a grid with data from 2 different tables. Table1: [PK]id(int), name(nvarchar), areaID(int) Table2: [PK][FK]areaID(int), areaDescription(nvarchar)
My cerrent query is: SELECT Table1.id, Table1.name, Table2.areaDescription FROM Table1 INNER JOIN Table2 ON Table1.areaID = Table2.areaID
However, sometimes the areaID in Table1 will only be populated at a later stage and therefore will be NULL in Table1. Table2 is used as a lookup table when inserting into Table1. This query therefore ommits any records in Table1 which do not have an areaID. I would like to view ALL records(ones without an areaID as well) as they would be populated in the grid and selected to be updated on web forms because they are incomplete and then subsequently assigned an areaID.
Any help with this query would be much appreciated...
How do I count the number of positive dollar values in a query? I have various negative and positive dollar values and want to count how many positive I have then I will know how many are negative. I cannot put >0 or >0.00 in the where because it still returns everything cuz the programmer set the datatype to be money
I need to return row counts for a list of all our users. The problem with the first query is that it doesn’t search for names within the column, it considers a list of email addresses a unique entry. I need to be able to see how many times each email address appears in the database. The second query obviously does that but I don’t want to have to copy and paste 500 usernames. the to_addr_head is a text column if that matters. Thanks!!
SELECT Table1.to_addr_head, COUNT(*) AS "COUNT(*)" FROM Table1 group by Table1.to_addr_head ORDER BY "COUNT(*)" DESC;
select count(*) where Table1.to_addr_head like '%username%'
Here is the desired counted output, I would like to pull distinct Date, MachineNumber, TestName and then count how many times they occur in the raw data form.I do need to perform a case on the date because right now its in a datetime format and I only need the date.
I am pulling three columns with the same names from 8 different tables. What I need to display the date, machine & test name and count how many times a test was run on a machine for that date. I have a feeling this can be handled by SSAS but haven't built an analysis cube yet because I am unfamiliar with how they work. I was wondering if this is possible in a simple query. I tried to set something up in a #Temp table. Problem is the query takes forever to run because I am dealing with 1.7 Million rows. Doing an insert into #temp select columnA, columnB, columnC from 8 different tables takes a bit.
I know I am missing something basic, here. I have a date field in a table. The field is 'allowed Nulls'. When a certain thing happens in the program, the date is filled in. At various times, I need to do a query to find all the rows that have no dates entered.
What do I use in my where clause? SQL server does not like 'where date = null.'
Suppose I have added a xyz bit column in mytable. From now onwards new values inserted in mytable will have 0 or 1 in xyz column but the values that were previously stored will have NULL value in xyz column.
Now I want to write a query in which I will not give xyz parameter always like it can be null or value.
select * from mytable where class='something' and xyz is null
or
select * from mytable where class='something' and xyz = 1
Im okay with simple queries but as Im no expert and have failed to find perhaps the correct wording to describe this method, if at all possible to do, so I have come to ask here.
What I would like to do is take a column from a query and then break down that column into separate results.
So the full query results: 36,18/09/2007 10:00:00,NULL,000102000304,NULL
The column I would like to brake down is (Unique Reference Number): 000102000304
And I would like to break it down to get the last 2 parts (0003 and 04): 0001 | 02 | 0003 | 04
Is this possible to do? If so where should I be looking or what should I be looking at?
