what I wanna achieve is to have a statement that selects distinct uniqueid's from the chapterID field and with every duplicate I would like to have the record with the highest version number
I would like to know if there is a way that I can use DISTINCT on one column's values but need to show other columns where the value of the DISTINCT column is equal to another table's column
How can i select all columns of table but to distinct by one column? i am tryin to figure it out without success, i know how to make distinct (select distinct column from table, but i need all the values from the table and to distinct by Delcompany.
Now i want to get the list of message IDs where the message Text Contains some Special characters as like the characters from the below image. how to query to get the list of message ids where the message text contains any one of this special characters.
Here is the query I have now which returns over 2 million records:
[Code]....
This works, but the result is littered with many rows that contain the same SSN. So how do I return only one row for each ssn? I cant use distinct because all of the other columns are already always different, this would return the same as above.

I would like to select a distinct query based on three fields and display the rest of the fields. For example,
I have firstname, lastname, address, city, state and zip, but I only want to use the distinct on these fields first and last name. However when i use the distinct function I get a distinct on all the selected rows. I just want to distinct firstname and lastname and display the other fields. for example,
Mary Smith New York Mary Smithy New York Mary Smith Maine
I would like the result to be:
Mary Smith New York Mary Smithy New York
I don't care about Mary Smith Maine, because i am only using the distinct for "Mary Smith" firstname and last name and showing the city.
My current project has many peripheral systems and many different environments (testing, integration, development etc). As expected, we're using .config files to dynamically manage everything.
Instead of updating each relavant key when deploying to an environment, I was hoping there was a way to change 1 key only. Such as:
I've done some searching and haven't come up with an elegant solution. I'm aware that .config files can make use of system variables, but this seems like a bit of a high wire act.
rowid pid gid dis 1 1222 aa dd 2 1222 bb cc 3 1222 cc dd 4 1331 vv cc 5 1331 cc zz 6 1414 zz cc 5 1414 xx zz
I need get distinct pid with rowid together. select * distince pid from tableone However, I get error: select rowid, distinct pid from tableone? Is any way to work out this one?
I am writting a custom class with which I manipulate the data for my website. I was wondering if there is a way to connect to a database and retreive the column names for a given table with out sellecting any data in the table.
Currently I am using an sql select and connection string to create an SqlComman object. Then I use the command object to create a SqlDataAdapter object which I use to fill a DataSet. At the end of all that I am able to retrieve the column names but I have select data and retreived data.
I have a table 'tbl' and a column 'col'. The elements are like 1,1,2,2,2,3,4,4. Now I want to show two columns one is the one will contain the distinct values from 'col' like 1,2,3,4.... and second will contain the count for each of them like for above case it will be 2,3,1,2.
Now, I want to select all unique locationid's from a single username, its important that the results can be PAGED and SORTED, I now have:
SELECT * FROM (select ROW_NUMBER() OVER (ORDER BY createdate) as RowNum, distinct(locationid), l.* FROM location_views lv INNER JOIN locations l on l.id=lv.locationid where lv.username='myname@hotmail.com' ) as info WHERE RowNum > 0 AND RowNum <= 100
But this throws the error: "Incorrect syntax near the keyword 'distinct'."
