I'm trying to use a function in my code behind to let me select a different column each time by calling the function with a different parameter.
However, I keep being told 'invalid column name', even though in the error page the column name appears perfectly valid.

How can I replace the field names in sql query string with variables like:-
string field1="ID";
string field2="Name";
sql = "Insert into [Sheet1$] ('" + field1 + "','" + field2 + "') values('1','abc')";
I am inserting data into an Excel document which has got nearly 100 columns.
I am inserting data using OLEDB as follows:-
System.Data.OleDb.OleDbConnection MyConnection ;
System.Data.OleDb.OleDbCommand myCommand = new System.Data.OleDb.OleDbCommand();
string sql = null;
MyConnection = new System.Data.OleDb.OleDbConnection(connectionstring);
MyConnection.Open();
myCommand.Connection = MyConnection;
sql = "Insert into [Sheet1$] (ID,Name) values('1','abc')";
myCommand.CommandText = sql;
myCommand.ExecuteNonQuery();
MyConnection.Close();
I want to specify the field names at runtime as mentioned above - sql = "Insert into [Sheet1$] ('" + field1 + "','" + field2 + "') values('1','abc')"; When I try this I am getting error.

I have been working with this database for some time. Here is the situation...
I inherited a MS SQL database that has hundreds of tables with similar data. For instance:
FordTampa_customer is a table,
ChevyAtlanta_customer is a table, etc....
All of the columns are the same...just different tables with their own ID field. All I have done...Inside of another database id is created a table called 'Customer' and added an 'Dealer ID' column along with the rest of the other columns in the other tables...
So the combination of the 'Dealer ID' and the 'ID' field are unique.....I know...its not the best way to do things...but I cannot change the old data structure because I cannot have access to it. I am give back-ups on a weekly basis, so this is all I have to work with.
All right, on to the real point of my post...
Currently, I have an application that I use to select all of the data from the 'Ford_customers','Chevy_customers',etc... and inserts them into my new main 'Customer' table. I do this by selecting the table names, bind it to an arraylist, loop through the list and execute an insert statement.
I do this in VB.NET, but I would prefer to do it in a Stored procedure of some kind....I just am not sure how to accomplish it. I use this syntax to get my list of tables:
[Code]....
I am not sure how to take those names from the table and do another select based on that list of names.
I am trying to create a multi column listbox by combining fields in Linq select statement, as Let Name = Last + First. The problem is how to pad the Last column with spaces as you would in SQL using REPLICATE so when I bind the listbox to the data, it looks like two columns.
View 5 RepliesI have the following SQL:
SELECT SRFILE_1.SRCONMAE, COUNT(LBWF_1.Incidentx) AS SLAFailed,
(SELECT COUNT(Incidentx) AS Expr3
FROM LBWF AS LBWF_2) AS TotalCalls
FROM SRFILE AS SRFILE_1 INNER JOIN

(LBWF_1.Chargex > '0.00') OR
(LBWF_1.LChargex > '0.00')
GROUP BY SRFILE_1.SRCONMAE
What I'm trying to do is divide TotalCalls by SlaFailed and * by 100 into a new variable such as Percentage. However, everytime I try to select SLAFailed or TotalCalls I receive a 'Column Names do not exist' message.
Is there any way I can reference said values?

I have to pull up a list of people by their branch number which could vary, and give a detailed report on there performance using a select queries. I have the select queries but how can i create a script to look similar to this one. Ive got the branch drop downlist already created just need to know how i can go about pulling all the users in this group and doing this select to all of them. someone told me I might need to use cursors to loop thru a select with every person in the list but im not sure how to go about that.
select fldusername from tbluser where fldio='o' and
flduserbranch=@branchid
is going to give me the names of the people i need to query. but how can i run a query on each of them seperate?
Here is the deal. I need to create a Stored Procedure that has 2 SELECT statements. Now in ASP.NET, I know that a DataSet can have multiple tables and the DataAdapter can do just that. I am stuck with a scenario where I need to get a value from the first SELECT statement which will later be used in the second SELECT statement. I am creating a SP that passes one parameter (@AnswerID). Which should give me 2 resultsets. See below SELECT statements.
[Code]....
So how do I get the QuestionID from the first SELECT statement?
Basically I am creating a Questionnaire that has Question Dependacies. So from the above SQL statements I would like to display the Question Title with it's relevant answer options but depending on the previous Answer selected hence the @AnswerID parameter.
The reason why I want to use 2 SELECT statements is because I don't want to have 2 roundtrips to th server. So in my code the DataAdapter should return 2 resultsets and fill the DataSet.
If there is any another solution that can prevent 2 roundtrips to the server, I would most definitely like to know how to do it.

this might be an easy one, but I just can't get it.I am creating a page which will query a table with many columns and most items are not unique. I need to be able to get a list of records that match as many of the (up to 4) search criteria as possible.Example:am user searching for the following items, I enter at least one and up to 4 of the items below in a text box:Name, age, gender, weight (user may or may not fill in all of them).If he just enters "F" for gender, then he will get a list of thousands of females with their name, age, gender and weight.However if he enters "F" for gender and "300" for weight, he will get a much smaller list of returned records.I need to be able to create a sql statement that can perform that search with that functionality.
View 6 Replieshow can i use Distinct in my sql statement like that
SELECT
Distinct * from my_table ?? ? ? ?? ? ? ?
here is a sql select statement,
Select
ColA = ID
,ColB = Name
,ColC = invtotamt + (SELECT SUM(TableA.camount) FROM TableA WHERE TableA.csucceed = 1 AND TableA.cID = InventoryTotal.invID GROUP BY TableA.cID)
,ColD = ((SELECT SUM(TableA.camount) FROM TableA WHERE TableA.csucceed = 1 AND TableA.cID = InventoryTotal.invID GROUP BY TableA.cID)
,ColE = (SELECT SUM(TableB.camount) FROM TableB WHERE TableB.csucceed = 1 AND TableB.cID = InventoryTotal.invID GROUP BY TableB.cID)
FROM TABLE
it look complicated, and long statement, actually it's easy, it is like: (it's a sample, not a really one)
Select
ColA = ID
,ColB = Name
,ColC = ColD + ColE
,ColD = ColE + ColC
,ColE = ColC + ColD/100
FROM TABLE
it looks much easier with ALIAS. But, it seems i cannot directly use alias in select stetement like that.
if i cannot use alise, i have to copy paste lots of same column definition. how can i use the alias in select statement?? this bothers me a lots of times!
I used an function in select statement. the select return 3 rows but the function return same value in this 3 rows.

SELECT u.Email FROM UserProfiles p, aspnet_Membership u WHERE p.RulesCheckBox = 'True' AND u.UserId = p.UserId This gives me a list of registered member email addresses that have selected the RulesCheckBox in their profile, so I can email them with an email script. There is a relationship between the Membership table and the UserProfile table, so it finds the email addresses from the Membership table where that user has the RulesCheckBox checked in their profile (in UserProfiles table). I'm wanting to add some additional names to this list, from a different table. The purpose is so I can manually add email addresses to the additional table, so the additional email addresses will also receive the same email, even though they aren't registered members of the site. So how can I adjust that SELECT statement so this one is combined with it somehow?:
SELECT Email FROM ExtraEmails WHERE Rules = 'true'
