i have a query like this and its running correctly
SELECT CAST(REPLACE(LTRIM(RTRIM(SUBSTRING(P.Telephone, 2, LEN(P.Telephone)))), ' ', '') AS BIGINT) FROM P INNER JOIN PCommunication ON P.ID = PCommunication.ID WHERE P.Telephone IS NOT NULL AND CAST(REPLACE(LTRIM(RTRIM(SUBSTRING(P.Telephone, 2, LEN(P.Telephone)))), ' ', '') AS BIGINT) > 5000000000 AND PCommunication.TypesID = '7667d187-5fe1-4aaf-9e31-79761561da58'
i am trying to use it with dynamic query like this but its not working
I have a query which is returning records like below which returns a list of tasks with a corresponding task type. there is a task table (wh_task) and a task type table (wh_task_type). What i want to achieve is a count of all the tickets per ticket type. So at the end of the query i will have a total for Administration / Maintenance tasks (1) and a total for Routine Maintenance Tasks (3). ** and all the other types *
There are many different types of task type so I dont want to have to hard code it. Can count all the occurencies of the different ticket types.
Task Name Task Type Date Completed SBS Server C drive running out of space Administration / Maintenance 16/07/2007 16:03:34 Patching Server(s). Routine Maintenance 08/01/2009 06:51:56 Patching Server(s). Routine Maintenance 11/02/2009 10:06:06 Patching Server(s). Routine Maintenance 04/05/2009 06:53:24
I set the CellPadding and CellSpacing properties to 0 and BorderStyle to 'None' on my gridview.
I set up a hover event on the row so that the entire row is highlighted on mouse over. When this happens, I can still see a gap between the two columns.Am I missing a property setting here?
1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.
By right clicking on my database i created a query in server explorer. But where are this query stored can't find them back. I should aspect that their is a folder query's like there is a folder tables but this isn't the case.
Dim MediaQuery = From m In dB.DOWNLOADS _Where m.ID = id _Select
which returns a record from the database. One of the fields in the record is a FK to another table. I need to read this value to be able to set a dropdown based on the ID but I can't work out how to access it. For a standard record I can just do the following txtTitle.Text = MediaQuery.FirstOrDefault().TITLE
However with the foreign key it doesn't work like that. I've tried drpGroup.SelectedIndex = MediaQuery.FirstOrDefault().DOWNLOAD_GROUPS.ID where DOWNLOAD_GROUPS is the FK field but it returns Object reference not set to an instance of an object. If you're simply wanting to read some values from a single db record in the entitiy framework and one is a foreign key how should I go about getting the value?
I have a datasource, which includes many columns, idealy, I need use a gridview to show:
1) first 3 columns: template fields, these fields depends on values in some columns of datasource. I use template fields, hard coded. works fine.
2) the other columns. This is I do not know how to do it. In the data source, there are about 10-20 columns data, each time, the # of columns of the data varies. idealy, I need show each of them as a seperated column in gridview. The entire data source may have 30 columns, but some of them are used in 1), and I only want show these 10-20 columns in gridview. Some columns in data source, I may not use them at all. is there a way to do this? or have to seperate them as a detail view style UI?
i'm writing a stored proc and if a field i return is longer then 200 characters, i want to truncate, find the last space, remove any characters after that space, then add some full stopseg:
INSERT INTO @rec(articleid, abstract) SELECT a.id, CASE
I want to create a constraint for 3 columns (A B and C) where if columns B or C are not null, then A cannot be null. And vice versa (i.e., if A is not null, then either B cannot be null, or C cannot be null).I am not very well versed in SQL and would like to know what is the best way to achieve this (e.,g Check constraint, stored procedure, function, trigger)? I'm leaning towards trigger but I'm not 100% sure if that's right nor of how to implement it.
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.
