Column Names
Dec 27, 2005
At 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.

Hi
I was wondering if anyone has an idea of how we could find the table names and column names of the tables in our Sql server database at runtime/dynamically given our connection string? Please let me know.
Thanks.

Hi
When I run this query..
SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME='TableTest'
I get all the column names, but the result is not in the same order as when I check the design for the table, why is that?

Hello,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

Hi,
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.

Can anyone help me with a SQL statement that will list all the column names in a table please ?
I just want to list out the column name so that i can develop asp/vb more effectively than having to use SQLEM and Design table to see the field names.:confused:
thanks

Is 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.

Hi All,
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 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!

Morning guys,
I have a project where Iam suppose to script all columns in every database/table/columns on the network.
I figured the best way to do this would be using sql-dmo (Sql Server 2000)
Does anyone have any suggestions on getting started with this project?
thanks,
Jonathan

Hello, everyone:
I used bcp to generate a txt file as:
EXEC master..xp_cmdshell 'bcp "SELECT * FROM Test..Orders" queryout "c:/test.txt " -U tester -P tester -c'
It works fine except without column names of table. Does any one have idea that can bring out column names from table?
Thanks

I 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

Hi 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.

I 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.

I'm trying to perform an insert on a table from another table, but
the fieldnames are different. The data is similar, but there are
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.

Got 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.

I am struggling on this issue and was hoping if anyone out there canhelp me.Here is the setup: I have a table with the following data:TableName: TranDetailMerchID ItemName Price------------------101 A 5101 B 3.5101 C 0102 B 7.6102 C 4102 E 65102 G 4103 K 35Table DesignMerchID intItemName varchar(50)Price floatWhat I would like is a report that looks like thisMerchID A B C E G K101 5 3.5 0102 7.6 4 65 4103 35This report can change on every run depending on data in tableTranDetail. The column name in report depends on ItemName in tableTranDetail. As seen in the above report, there is no data for Items D,F, H, I, J and hence they do not show up in the report.What I need: Code for a stored procedure that can get me this data.Thanks for your help...DBA in despair!

I'm dealing with a database with tables that have freaking columns.Partial DDL:Create table [tbl IMN] ([Ave Cost-Mn] varchar(10))-- yeah, this column contains string valueNow, I'd like to rename all these freaking columns without specialcharaters like '-', 'whitespace' etc systematically (meaning loopthrough all tables and columns dynamically). It seems that thesp_rename proc can't handle some function call or ...?e.g.exec sp_rename '[tbl-IMN].[Ave Cost-Mn]',replace('[AveCost-Mn]','-',''),'COLUMN'better if it can work,exec sp_rename '[tbl-IMN].[Ave Cost-Mn]',replace('[Ave Cost-Mn]','-|',''),'COLUMN'TIA

Can the column names be change in SQL Express.
I am amist of pulling my hair out here, I have got a scenerio of needing to be able to move data around, my first thought was to have two columns, one for the data and the other for the column name. Once getting into the manipulation of the data, it occurred. MUCH EASIER to modify the column name in the data table rather the data.
Is it possible from VB to change the name of the column in the database table?
Thanks Again

Hi guys 'n gals,
I am trying to achieve something a bit complex (or at least appears to be for me).
I have the following table structure:
UID, GroupID, ColumnName, ColumnValue
here is some example data:
UID, GroupId, ColumnName, ColumnValue
1, 1, MAC Address, 8a7sd87sad
2, 1, IP Address, 192.168.1.100
3, 1, Name, John
4, 2, MAC Address, 09a8sd098as
5, 2, Name, Steven
and here is what I would like the example to come out like:
GroupID, MAC Address, IP Address, Name
1, 8a7sd87sad, 192.168.1.100, John
2, 09a8sd098as, NULL, Steven
It needs to be completely dynamic though, as a new column name could be entered to the source table at any time...
I have tried Dynamic SQL and JOINs, but can only seem to get it to work correctly. I was starting to consider doing a loop similar to this:
Code Snippet
DECLARE @ColumnName varchar(128)
DECLARE @Sql varchar(255)
SELECT @ColumnName = [ColumnName] FROM tblSourceData
SELECT @Sql = 'SELECT [GroupId], [ColumnValue] AS ['+@ColumnName+'] FROM tblSourceData'
EXEC (@Sql)
Could somebody please point me in the right direction? I've heard a bit about Pivot tables in my search for this solution, is that perhaps the route I need to go?
Regards,
Justin
