Jul 20, 2005I have some columns of data in SQL server that are of NVARCHAR(420)format but they are dates. The dates are in DD/MM/YY format. I want tobe able to convert them to our accounting system format which isYYYYMMDD. I know the format is strange but it will make things easierin the long run if all of the dates are the same when working betweenthe 2 different databases. Basically, I need to take a look at theyear portion (with a SUBSTRING function maybe) to see if it is greaterthan 50 (there will not be any dates that are less than 1950) and ifit is concatenate 19 with it (ex. 65 = 1965). Then, concatenate themonth and day from the rest to form the date we need in NUMERIC(8).So, a date of January 17, 2003 (currently in the format of 17/01/03)would become 20030117. In VB, the function I would write is somethinglike the following:/*Dim sCurrentDate as StringDim sMon as stringDim sDay as StringDim sYear as StringDim sNewDate as StringsCurrentDate = "17/01/03"sMon = Mid(sCurrentDate, 4, 2)sDay = Mid(sCurrentDate, 1, 2)sYear = Mid(sCurrentDate, 7, 2)If sYear < 50 ThensYear = "20" & sYearElseIf sYear > 50 ThensYear = "19" & sYearEnd ifsNewDate = sYear & sMon & sDay*/I was thinking of doing this in a Stored Procedure but am really rustywith SQL (it's been since college).The datatype would end up being NUMERIC(8). How I would write it if Inew how to write it would be: grab the column name prior to theprocedure, create a temp column, format the values, place them intothe temp column, delete the old column, and then rename the tempcolumn to the name of the column that I grabbed in the beginning ofthe procedure. Most likely this is the only way to do it but I have noidea how to go about it.

Column Names
Dec 27, 2005At my work, we are upgrading a number of MS Access 2000 databases to SQL Server 2000. Many of the columns have names that do not follow the rules for Identifiers. For example there are columns with a numeric names 1,2,3,4,5,6,7,8,9. There are also columns with a hyphen in the name and columns that begin with a number and not an underscore or an alpha character. Plus there are columns with names like first, last, position, etc. (There was also columns with reserved words used as the names. I have changed those column names in the databases that I have already converted) Will leaving these names alone create a problem? The database serves as the backend to ASP pages.

Dynamic Column Names In A SP
Jan 1, 2008Hello,I'm still extremely novice to SQL and I've tried googling how to produce this result but I've been encountering a lot dynamic sql commands which isn't exactly what I want. If this is an ignorant question I do apologize but heres my scenario: I have a table with columns of the day, for instance: Monday_hasData (bit)Monday_DataAnd what I want to do is essentially pass in "Monday" as a parameter and rather than doing an If statement on each row, I would like to just like to do something like assign @dayCheck + "_hasData" to a variable and then use @dayCheck as part of my query. Is this possible or am I going to have to have 7 cases? Thank you for any input,Chance

How To Get Column Names Which Are Not Null
Jul 12, 2002Hi,
I have a table in which out of 20 columns, there will be data only in a few columns. So, I need to find those column names which have data in them. I was able to do it using the information_schema and using a cursor to loop through all the column names and find out which columns have data in them. But i need to know if there is a more efficient way of doing this without using the cursor. Can somebody please let me know how this can be done without using a cursor? Thank you.

Get Column Names From All Tables In A Db
Mar 7, 2005Is there a way that you could get the column names for each table in a database using 1 query?
something like:
tbl colname
t1 catID
t1 catName
t2 prodID
t2 prodDesc
t3 cartID
...
...
I know it would be long, but I would just be searching through the saved output for specific names.
Get Column Names From Table

I was wondering how would I get the column names from a table? Not the results just a listing of column names. What is the command to get this information? I am using MS Access, but I posted here because MS SQL is the closest thing on this forum and the syntax is usually similar.
Thanks a bunch.

SQL Keywords As Column Names
Oct 13, 2005SQL server throws an exception when I try to run the following code:
ALTER TABLE contacts ADD default ntext NULL;
The reason for that is that "default" is an SQL keyword.
The way I handle this now is I put an underscore at the front:
ALTER TABLE contacts ADD _default ntext NULL
Is there a cleaner way to handle this, i.e. to keep the column name "default" and forse sql server to create a column with this name?
Thank you!

I used bcp to generate a txt file as:

Variable Column Names
Mar 15, 2004I am writing a stored procedure in which I have a query that selects the Headings of Columns from another table...
I want to then create a loop that will contain a variable with the value of the column heading and then set the column to a value of NULL...
Is there any way to accomplish this???
I thought about placing these values into a temp table...
This is what I have so far...
Declare @QueryX nvarchar(500)
Declare @FieldName varchar(20)
Create Table #UpdateRejDoc
(
Abbreviation varchar(20)
)
Insert into #UpdateRejDoc
Select Abbreviation
From tbl_Titles
left JOIN tbl_TitleRouting on tbl_Titles.Title_ID = tbl_TitleRouting.Title_ID
Where tbl_TitleRouting.Application_ID = @Application_ID
While Exists (Select Abbreviation from #UpdateRejDoc)
Begin
Set @QueryX = 'Update DBLandfillUser.tbl_ObjectApprovals' +
'@AppName + Set @FieldName = null Where object_id =' + Cast(@object_id as VarChar(20))
End
Caching Column Names
Apr 22, 2008Hi All,
Heres my problem...
If I create a table T1 with a couple of columns; MyPKCol, ColA
I then create a view V1 as "Select * From T1"
At this stage, if I run "Select * From V1" the result will, as expected, include following columns:
MyPKCol,ColA
If I now add another column, ColB, to T1 and then again run "Select * From V1", I still get the result with only 2 columns;
MyPKCol,ColA
In order for V1 to return MyPKCol,ColA,ColB I have to drop V1 and then recreate it again.
Can someone explain why this is and how I can clear this type of cache?
I've tried the following commands, but it didn't work:
DBCC FREEPROCCACHE;
DBCC FREEsystemCACHE( 'ALL' );
DBCC DROPCLEANBUFFERS;
There has to be an easier way than having to recreate SPs, Function and Views just because you make a change to a table.
I hope I made sence
Thank you in advance for any help.

Replacing Some Names In Column But Not All
Dec 2, 2013I have a SQL table with 5000 rows in it. Some of the other SQL columns have different values but if I wanted to swap say 500 of the rows would it be something like
UPDATE Coupins
SET Name='test1,test2,test3'
WHERE Name='test4,test5,test6';
I need basically to swap the Name value of these without affecting any other values.
Inserting With Different Column Names

less fields as well. Does anyone know how to accomplish this? All
the material I've read on the Internet so far pertaining to Insert
statements, has all the column names matching up.
Any help would be greatly appreciated.
Dynamic Column Names
Aug 28, 2007Got my first real job to do in SSIS and it's not really much fun. Here goes. I have excel files from various vendors, none of which are in the same format. Now I'm less concerned with the names, I have those in variables so that's not a big deal. My issue is around the column names. Let's say we have file a, b and c. In file a the first name field is called [first name], in file b it's first_name and in file c it's firstname. What I want to do is create 1 package that can handle these files regardless of how first name is spelled. I was thinking I could open the file and somehow search for a column name that contained the word "first%" and then map the column name to a variable. I'm sort of stuck though on how to actually do that. Help. And please don't tell me to tell the vendors to standardize. That's the end goal but it's like herding cats.
