Also, i need to store the time of every change employee makes on EmployeeName e.g. if the name essentially is James and time created is 9:00 AM and then employee changes to John ...

a) Quote is taken from http://www.postgresql.org/docs/current/static/tutorial-window.html for each row, there is a set of rows within its partition called its window frame. Many (but not all) window functions act only on the rows of the window frame, rather than of the whole partition. By default, if ORDER BY is supplied then the fra...
Are there any constants in T-SQL like there are in some other languages that provide the max and min values ranges of data types such as int? I have a code table where each row has an upper and lower range column, and I need an entry that represents a range where the upper range is the maximum value an int can hold(sort of like a hackis...
I am making an URL shortener, and I am struggling with the optimal way of encoding a number (id) into a character string. I am using the characters 0-9,A-Z,a-z so it will basically be a base-62 encoding. That is pretty basic, but it doesn't make use of all possible codes. The codes that it would produce would be: 0, 1, ... y, z, 10, 11...

I need to: Pull in all distinct records for values in the "eventid" column for a time frame - this seems to work.

I'd like to select and display t...
We have a scalar function that returns a DateTime. It performs a couple of quick table selects to get its return value. This function is already in use throughout the database - in default constraints, stored procs, etc. I would like to change the implementation of the function (to remove the table hits and make it more efficient) but ap...

I have a couple of stored procedures in T-SQL where each stored procedure has a fixed schema for the result set. I need to map the result sets for each procedure to a POCO object and need the column name and type for each column in the result set. Is there a quick way of accessing the information? The best way I have found so far is ac...
Here is my scenario: we have a database, let's call it Logging, with a table that holds records from Log4Net (via MSMQ). The db's recovery mode is set to Simple: we don't care about the transaction logs -- they can roll over. We have a job that uses data from sp_spaceused to determine if we've met a certain size threshold. If the thre...
I basically want to do this: SELECT HasComments = CASE (LEN(Comments) > 1) WHEN 1 THEN 1 ELSE 0 END FROM TableName In other words, return a boolean telling me whether the length of Comments is greater than 1. This gives me a syntax error. How can I accomplish this? ...
What do I need to consider before I switch a bunch of fields from VARCHAR(bignumber) to TEXT? Aside from performance, and sometime in the far future TEXT will be deprecated, and aside from the fact that it looks like I need to drop and recreate the table to alter the column's data type? This is for SQL 2000-- I can't do VARCHAR(max) an...
