This question is for wrapping up work on a database driven AJAX AutoComplete Control that I am using to provide keyword hints to user on search pages. Each record has 6 columns for keywords where each column is for an advertiser to add a keyword. These are used in meta keywords tags, but I also want to use them for AutoComplete. The problem is that I don't know how to write a SELECT statement in Visual Studio that treats all 6 keyword columns as if they were all one column. I am looking for something like
SELECT (keyword1 + keyword2 + keyword3) AS Keywords FROM (Merchandise) WHERE Keywords LIKE @term
The only other thing I can think of the gain this level of functionality would be to combine them into a new table.
I don't know if I'm posting this in the right place - I have a feeling it can't be too difficult but I can't seem to figure it out. I've come across this problem many times and I've never solved it. I would imagine the scenario is commonplace - I have a table of Products with a PK of ProductID, and a table of related images with a FK of ProductID. Each product can have many images, but for my initial display I want to display one product record with one image record. I have a Sequence field in the Images table and I could pick the lowest one. Right and left Joins return too many records - if I have three images for Product 1 then Product 1 is listed three times.
I've gotten around this before using a flag in the Products table, or listing an image in both tables but I'm sure there must be a SQL statement that can get the information that I need.
I've got a TextBox to capture the value of "Name" in Table A.
Ive got a CheckBoxList that displays all the pre-determined values of Table B.
When the user selects an item from the CheckBoxList i want to populate Table C with the value of the selected item from the CheckBoxList and the cooresponding ID associated with the user name for that person's entry.
I want to select the number of goals, assist and cards a player has in a specific tournament. I tried with this query but then the goal and card column shows the sum of the number of rows matching the playerid in the Goal table and the Card table...For example if there is two matching rows in the goal table and three matching rows in the card table, I get 5 in both these columns in the resultset.
i have a form view that takes fields from two tables 'Contract' and 'volunteers', however because i used a query builder,i have to input an insert statement. How do i create an insert statement for two tables in one query?
You notice "Cough" is in the adidescription column twice. I would like to return only one row for adidescription with the same value. So what I want returned is this:
I'm facing a problem in our current running application. There is a table in database which has 67 columns,among these 18 columns are nvarchar(max) datatype and contains 30K records. Problem is now that SELECT * FROM myTable it takes around 3 to 4 seconds. Which is degrading our application's performance.
I want to know that how many tables we can have in database and what is the maximum no. of columns.I also want to know the maximum size for each datatype.
I need to join some tables to get the matching records. I often have to ask around to see how certain tables could be joined. Is there any way to query the information schema or some thing else to see what columns/values match in certain tables in order to figure out how tables should be joined.
Dim AlterTable As String = "alter table [Upload] add [Country] nvarchar (50) default 0 NOT NULL,[Address] int default 0 NOT NULL"
Dim connection As Data.SqlClient.SqlConnection connection = New Data.SqlClient.SqlConnection() connection.ConnectionString = ConfigurationManager.ConnectionStrings("ASPNETDBconnectionString1").ConnectionString Dim cmdUpdating1 As New Data.SqlClient.SqlCommand(AlterTable, connection) cmdUpdating1.CommandType = CommandType.Text connection.Open() cmdUpdating1.ExecuteNonQuery() connection.Close()
This is the code which I am using for altering the number of columns in a table in the DB. so with this code i am able to add new coulmns dynamically. Now my major requirement in this is to obtain the headercount from the user( say "telephone number" and "language") and based on it generate the columns dynamically in the table in the DB.
I have a couple of things that are not working with my Gridview:
1) I've managed to display 3 columns in one column (see code above) but the data is separated by commas, how can I display each data item in separate rows.
2) How can I make the data unique, as I have added the distinct command which I configured in my SQL data source
3) I need the rows to not display nulls, but at the moment it isn't displaying the row if one of the columns is null?
I have a select statement. I need to get a field value from the first statement. GOAL: Below is what I am trying to accomplish - the code below is not correct - Please modify the statement with the correct SQL Syntax. I want to query a table and based on the results I want to set the "If THE Else"statement to query then table with diffent inner joins.
SELECT * FROM CONTENTITEM CI INNER JOIN CONTENTCATEGORY CC ON CI.CATEGORYID = CC.CATEGORYID IF CI.FORMTYPE = 200 OR 300 SELECT * FROM CONTENTITEM CI INNER JOIN CONTENTCATEGORY CC ON CI.CATEGORYID = CC.CATEGORYID INNER JOIN CONTENTFORMFIELD CF ON CF.ITEMID = CI.ITEMID WHERE CI.ITEMID = @ITEMID ELSE SELECT * FROM CONTENTITEM CI INNER JOIN CONTENTCATEGORY CC ON CI.CATEGORYID = CC.CATEGORYID WHERE CI.ITEMID = @ITEMID
The main problem is that I recieve the following message:
"base {System.SystemException} = {"Unable to create a constant value of type 'BokButik1.Models.Book-Author'. Only primitive types ('such as Int32, String, and Guid') are supported in this context."}"
based on this LinQ code:
[Code]....
How shall I solve this problem to get a class instance that contain with property title and Book-AuthorID?I also have tried making some dummy by using "allbooks" relation with Code Samples from the address
http://www.hookedonlinq.com/JoinOperator.ashx. Unfortunately, still same problem.
I also have taken account to Int32 due to entity framework http://msdn.microsoft.com/en-us/library/bb896317.aspx. Unfortunatley, still same problem.
Using database with 3 tables and one of them is a many to many relationship. This database is used in relation with entity framework
I'm fairly new to all this, but have slowly been teaching myself C# and ASP.net MVC over the past year or so...I really tried to search for this, but haven't been able to find anything - it may be I'm using the wrong terminology!I'm using ASP.NET MVC2 with EF4 connected to a SQL Express db. Situation: Without getting into too much specifics, I have one table called 'Plan.' Under 'Plan' are several different categories that are related to a single Plan item [say Category A, Category B, Category C and Category D]. Each 'Category X' table has a beginDate, endDate and other details specific to that category.
I'd like to be able to create a summary page that combines all items from Category A, Category B, Category C, and Category D and sorts by beginDate - but only need a few of the columns [eg - begin/end date, name, id].
This all works just fine. However now, I want to take a date that's given, and make a "Past Due" column for anything less than the first of the month of that date.
The case is: I use a webservice that gives me information about companys. For example: I entered a companyname and the webservice give me a list of al company's in the country. The webservices return a one dimensional array. The problem is that I must search in two register so the webservices returns 2 array's. I put the data from both arrays into 2 datatables. The data in the 2 datatables can be different or the same.
The question is: How could I matching the data on ID and combine the data into 1 datatable.
The code:
//Create result SearchResult Result1; SearchResult resultZoekmogelijkheid2; //send van Soap Request
I have a table that contains a date column along with others. I need to extract two sets of data from this table for two different time periods. Call them Current and Previous, so that I can compare them line for line. There are exactly the same number of days in both time periods.
The problem is that I need to return the data like this:
