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...
Can you please tell me the way to configure the LOOK UP transformation so that it will ignore all the null values ? I want to configure a Look up component for the column "Col1" as follows
All the NULL values of Col1 should not be considered for look-up process. They should be passed to the downstream component as valid rows. All NOT NULL values of Col1 should be processed by the Look up component. If there is no matching value present for any NOT NULL value of Col1 then it should be directed to error output.
CREATE TABLE A (ID INT IDENTITY (1,1)) CREATE TABLE B (ID INT, EMPID VARCHAR(10)) INSERT INTO A DEFAULT VALUES GO 5 INSERT INTO B VALUES (1,'E23') INSERT INTO B VALUES (1,'E24') INSERT INTO B VALUES (2,'E23')
from the above code i would like to get output like
I have tried all possible combinations of changing this. But was not able to make the results tally.I am giving you a part of the query, there are others queries involving 4 tables which are based on this same temporary table query.
SELECT c.juris_id, b.jrnl_mo_yr FROM a_trueup a, #t_mths b, r_rj c WHERE a.rlzd_mo_yr =* b.jrnl_mo_yr AND a.juris_id =* c.juris_id

I tried using left outer join as mentioned in blogs but got a different result (14 rows).I also used set null off/on options but no luck ..
Hi, I am using SQL Server 2000. In database i am having one column named Address which contains full address of the customer. While searching i want to ignore starting numeric or alphanumeric values. Kinly guide how I can ignore numeric or alphanumeric values while searching the data.
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 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?
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 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 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!
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";
So I have this query that is ignoring my date filter and for the life of me I can't figure out why. Was hoping some guru could explain it to me. Here goes:
This query ignores my date filter:
SELECT rcv.Name AS MachineName, r.JobId, j.Name AS JobName, r.CreateTime AS JCreateTime, rsv.Name AS JResultStatus, rpv.Path + rpv.Name AS ResourcePool, rcvv.ResourceConfigurationVal AS Dimension
FROM dbo.Result_View AS r INNER JOIN dbo.ResourceConfiguration_View AS rcv ON r.ResourceConfigurationId = rcv.Id INNER JOIN dbo.Job_View AS j ON r.JobId = j.Id INNER JOIN dbo.ResultStatus_View AS rsv ON r.ResultStatusId = rsv.Id INNER JOIN dbo.Resource_View AS rv ON rcv.ResourceId = rv.Id INNER JOIN dbo.ResourcePool_View AS rpv ON rv.ResourcePoolId = rpv.Id RIGHT JOIN dbo.ResourceConfigurationValue_View AS rcvv ON rv.LatestResourceConfigurationId = rcvv.ResourceConfigurationId LEFT JOIN dbo.Dimension_View AS d ON rcvv.DimensionId = d.Id
WHERE (r.CreateTime > DATEADD(DAY, -15, GETDATE())) AND (rcv.Name LIKE 'PNP%') AND (d.Id = 859) OR (d.Id = 860)
If I comment out the last two joins and associated select/filters, all of the sudden the date filter works again. From everything I have read, the joins are supposed to be processed BEFORE the filters are applied in the virtual table. My DB goes back a number of years and contains millions of records. W/O the date filter, the query takes a very, very long time to run.
HiConsider two tablesid1 code1----------- -----1 a2 b3 cid2 code2 value----------- ----- -----------1 a 02 a 13 b 1They are joined on the code field.For each code, I want the maximum corresponding value. If the valuedoesn't exist (corresponding code in second table doesn't exist), I wanta NULL field returned.The result should look like this:code2 value----- -----------a 1b 1c NULLI can't get it to include the NULL row.While there are uniqe ID's in this example, the real life example uses ahorrible four field compound key.Any help would be appreciated.Ger.The above example can be recreated by the following script.DROP table #temp1DROP table #temp2SELECT 1 AS 'id1', 'a' AS 'code1'INTO #temp1UNIONSELECT 2, 'b'UNIONSELECT 3, 'c'SELECT 1 AS 'id2', 'a' AS 'code2', 0 AS valueINTO #temp2UNIONSELECT 2, 'a', 1UNIONSELECT 3, 'b', 1SELECT code2, valueFROM #temp1 t1LEFT JOIN #temp2 t2 ON t1.code1 = t2.code2WHERE CASEWHEN t2.value IS NULL THEN 1WHEN t2.value = 0 THEN 2WHEN t2.value = 1 THEN 3END = (SELECTMAX( CASEWHEN value IS NULL THEN 1WHEN value = 0 THEN 2WHEN value = 1 THEN 3END )FROM#temp2WHEREcode2 = t2.code2)
I have a DTSX package which reads values from a fixed-length text file using a data reader and writes some of the column values from the file to an Oracle table. We have used this DTSX several times without incident but recently the process started inserting NULL values for some of the columns when there was a valid value in the source file. If we extract some of the rows from the source file into a smaller file (i.e 10 rows which incorrectly returned NULLs) and run them through the same package they write the correct values to the table, but running the complete file again results in the NULL values error. As well, if we rerun the same file multiple times the incidence of NULL values varies slightly and does not always seem to impact the same rows. I tried outputting data to a log file to see if I can determine what happens and no error messages are returned but it seems to be the case that the NULL values occur after pulling in the data via a Data Reader. Has anyone seen anything like this before or does anyone have a suggestion on how to try and get some additional debugging information around this error?
Hi all, I am using a SQL statement with a JOINs to display a summary list of Work Orders with some information from the related Purchase Order. I don't require that a Work Order be attached to a Purchase Order, so the JOIN field, POLineItemID, may not be present. My current problem is that my summary page does not show Work Orders that have a NULL value for POLineItemID -- ie, the JOINing field becomes required. How can I continue to use this JOIN structure but still return rows that don't have this JOIN field? Thanks in advance for your help. Here is my SQL statement for this... SELECT tblWorkOrder.WorkOrderNumber, tblWorkOrder.ActualCompletionDate, tblWorkOrder.EstimatedCompletionDate, tblWorkOrder.AssignedTo, tblWorkOrder.DelegatedTo, tblWorkOrder.Due, tblPurchaseOrders.PONumber, tblWorkOrder.POLineItemID, tblPOLineItems.POLineItemID AS Expr1, tblPOLineItems.PurchaseOrderID, tblPurchaseOrders.PurchaseOrderID AS Expr2, tblProducts.ProductID, tblProducts.ProductCategory, tblWorkOrder.ProductID AS Expr3, tblWorkOrder.WorkOrderStatusFROM (((tblWorkOrder INNER JOIN tblPOLineItems ON tblWorkOrder.POLineItemID = tblPOLineItems.POLineItemID) INNER JOIN tblPurchaseOrders ON tblPOLineItems.PurchaseOrderID = tblPurchaseOrders.PurchaseOrderID) INNER JOIN tblProducts ON tblWorkOrder.ProductID = tblProducts.ProductID)ORDER BY tblWorkOrder.Due
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?
can somebody explain me how I can assign a NULL value to a datetime type field in the script transformation editor in a data flow task. In the script hereunder, Row.Datum1_IsNull is true, but still Row.OutputDatum1 will be assigned a value '0001-01-01' which generates an error (not a valid datetime). All alternatives known to me (CDate("") or Convert.ToDateTime("") or Convert.ToDateTime(System.DBNull.Value)) were not successful. Leaving out the ELSE clause generates following error: Error: Year, Month, and Day parameters describe an un-representable DateTime.
My query "select blah, blah, rank from tablewithscores" will return results that can legitimately hold nulls in the rank column. I want to order on the rank column, but those nulls should appear at the bottom of the list
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.
Hi, I ve a table, I want to fetch certain rows based on the value of a Column. That column is nullable, and contains NULL values.I used the following query,SELECT Col_A FROM TABLE1 WHERE SOME_ID = 1317 AND Col_B NOT IN (8,9) Here, Col_B contains NULL values too. I need to fetch all rows where Col_B is not 8 or 9.Now, if I use "NOT IN", it does not work. I tried reading on it and got to know why it does not work. Even "NOT EXISTS" does not help. But still I've to fetch my values. How do I do that?Thanks & Regards,Jahanzeb
I have tried doing a search, as I figured this would be a common problem, but I wasn't able to find anything. I know that my SP is functional because when I use VWD execute the query outside of the webpage, I get the correct results -however I have to ensure that a field is either entered, or set to <NULL>. In my SET's I want it to use the wildcards. What I want is to do a search (plenty of existing topics on that, however none were of help to me). If a field is entered, then it is included in the search. Otherwise it should be ignored. In my VB I have the standard stored procedure call, passing in values to all of the parameters in the stored proc below: CREATE PROCEDURE dbo.SearchDog@tagnum int,@ownername varchar(50), @mailaddress varchar(50),@address2 varchar(50),@city varchar(50),@telephone varchar(50),@doggender varchar(50),@dogbreed varchar(50),@dogage varchar(50),@dogcolour varchar(50),@dogname varchar(50),@applicationdate varchar(50)AS IF @tagnum=-1 SET @tagnum=NULL SET @ownername = '%'+@ownername+'%' SET @mailaddress = '%'+@mailaddress+'%' SET @address2='%'+@address2+'%' SET @city = '%'+@city+'%' SET @telephone='%'+@telephone+'%' SET @dogcolour='%'+@dogcolour+'%' SET @dogbreed='%'+@dogbreed+'%' SET @dogage='%'+@dogage+'%' SET @doggender='%'+@doggender+'%' SET @dogname='%'+@dogname+'%' SET @applicationdate='%'+@applicationdate+'%' SELECT DISTINCT * FROM DogRegistry WHERE ( TagNum = @tagnum OR OwnerName LIKE @ownername OR MailAddress LIKE @mailaddress OR Address2 LIKE @address2 OR City LIKE @city OR Telephone LIKE @telephone OR DogGender LIKE @doggender OR DogBreed LIKE @dogbreed OR DogAge LIKE @dogage OR DogColour LIKE @dogcolour OR DogName LIKE @dogname OR ApplicationDate LIKE @applicationdate ) AND TagNum > 0GO I don't know why it is creating links inside my SP -ignore them. TagNum is the primary key, if that makes a difference. On the webpage, it ONLY works when every field has been filled (and then it will only return 1 row, as it should, given the data entered). Debugging has shown that when nothing is entered it passes "". Any ideas?
I am trying to retrieve data from two different tables. One of the tables has more than 20 columns some of which are null. I would like to retrieve data from both tables excluding the columns which have null values. How do I do this?
Would this take care of null values in either a.asset or b.asset?
SELECT convert(decimal(15,1),(sum(isnull(a.asset,0))/1000.0)+(sum(isnull(b.asset,0))/1000.0)) as total_assets
What's throwing me off is that there are multiple a.asset or b.asset for each unique ID. It seems to work, but I'm not following the logic too well. If I were doing this in another language, I would loop through, summing a.asset and b.asset wherever it's not null for each unique ID.
How can I use "Derived Column" to check if a Datetime value is null or not and if null to insert 00/00/00 instead. ?
The background being that while using a "Derived Column" to change a Column from a (DT_DATE) to a (DT_DBTIMESTAMP) everytime I get a null value it see's it as a error.
And the column in particular has ~ 37 K blank / null fields so Im getting a lot of errors
So far I have tried to use something like
ISNULL([Column 34])
Or
SELECT ISNULL(ID, '00/00/0000') FROM [Column 34]
Or
SELECT ISNULL(au_id, '00/00/0000 00:00') AS ssn FROM [Column 34
but none seems to work [Column 34] being the offending column.
What a normally use is just a simple "(DT_DBTIMESTAMP)[Column 34]" in the expression column, which seems to work well, but here I get alot of errors
I set up a new SQL database file, in that file I allowed nulls, When I went through code to save the record, the exception is saying it doesnt allow nulls.
Before I get to involved with SQL, is it a bad practice to use nulls?
If it is what do you enter in place of the null value,
Hi all,Just after some help with a query (Stored Procedure) I've managed to get wrapped round my head.The DB is as such:
COMPANY Company_id Company_name COMPANY_GROUP Group_id Group_name USER User_id User_name Bridging tables
COMPANY_GROUP_BRIDGE company_id group_id
USER_COMPANY_BRIDGE user_id company_id Basically, the only parameter I have for the query is a User_id.I need to get the Group linked to the User and return all the companies within that group. I've tried reading up on all the join types again but have just got this completely wrapped round my neck. I keep thinking along the lines of SELECT all the companies linked to all the groups linked to all the companies linked to the User_id :s I must be able to do this without using two Company tables...? Any help much appreciated,Pete
I have Categories table with CategoryID, Title, CategoryParentID columns Questions table with QuestionID, Text columns CategoriesQuestions table with CategoryID, QuestionID columns Now I want to make the query which takes QuestionID and return all Categories of that provided QuestionID. I already have made that query in 2 different styles. First I make an Inner Join to retrieve the results Select Categories.* from Categories Inner Join CategoriesQuestiosn on Categories.CategoryID = CategoriesQuestions.CategoryID where CategoriesQuestions.QuestionID = 1 Second I make a sub query to retrive the results. Select * from Categories where CategoryID In (Select CategoryID From CategoriesQuestions where QuestionID = 1) Now I am asking what is the better one in respect to performance. And please provide any other query if you have.
Iwrote a query right, and need to get further information out of another table, so did a Join, but then also need to get further information out of another table..So, I need to add this query:

For a given day, in this example 3/5 if I were to just select all the records I would get back around 550,000. If I put the filter on where I tell it to just show me one account its snappy. If I remove that filter and have it show me all the accounts it take forever. Here is the layout of my positions table where i am pulling the majority of the information:

GO SET ANSI_PADDING OFF
My questions is if you can identify any reason why the query might take more than 10 minutes (actually still running after 10 minutes) to complete when I have it bring me back all the records, not sure if its a lack of indexes or what, but was hoping for some suggestions on what I might be missing. I apologize if I havent included enough information, still learning how to troubleshoot the performance side of things.
hi ive got a inert sub where i grab values from text boxes etxthe values are passed to a stored procedure however , one of these fields is a date field , but the field is not required ...so on this line if the date text box is left blank i get an error , not a valid date .Parameters.Add("@actiondate", SqlDbType.DateTime).Value = txtActionDate.Texti have tried ( the actiondate field can take nulls ..)if txtActionDate="" then .Parameters.Add("@actiondate", SqlDbType.DateTime).Value = nothing else.Parameters.Add("@actiondate", SqlDbType.DateTime).Value = txtActionDate.Textend if but this doesnt workwhat is the best way of allowing blank values to be passed to the stored procedure( it doesnt fall over with normal text / varchar fields ) thanks
I have a sproce that accepts null for one of its parameters I can execute the sproce and enter null and it works fine, it returns all rows. When I try doing this with my GridView and the SQLDataSource it does not work. I need some help in understanding how the SQLDatasource wants a null.
