hey everyone, need some help
I have a query return all the names of the table in my database via this code:
SELECT MSysObjects.Name
FROM MSysObjects
WHERE (((Left([Name],4))<>"MSYS"));
I need to further refine the search fitting in the critera LIKE 'qry_tbl%' I dont know how to fit this in .. i tried fitting it in to the end, but nothing comes up.. I also tried querying the results of this query with another query :-P but that didnt work either .. any ideas?
In essence i need all the table names in my DB that start with 'qry_tbl' to be in a list for me..
Thx
Doc

I'm currently implementing a German ERP system and I'm having aterrible time writing reports/SQL statements. The database is MS SQLServer 2000. I want to set permanant aliases for the columns that Ican use in SQL statements. Is this even possible? All of the researchI've done implies that you can only alias column names in the output ofa SQL statement.

I'm not a full-time DBA, so excuse my style of expressing my question.I have a database which has 2 tables in SQL 2005. Both these tables have similar column names, EXCEPT for new extra columns in FY2007_DATA. I can visually see the difference in columns in Database Diagrams. My goal is to :- I want to compare FY2007 tbl column names to FY2006 column names and display only those columns as results that do not match.Tbl 1 :- FY2006_DATA Tbl 2:-
FY2007_DATA
With online reading and help I have managed to get this script to do exactly opposite of what i want. Below is the query
/* This query compares the column names from two tables and displays the ones that have an exact match. It does not care for case-sensitiveness */
Select a.Table_Name, a.Column_Name, (b.Table_Name), (b.column_name)
From [2006-2011].INFORMATION_SCHEMA.Columns AS a
Join [2006-2011].INFORMATION_SCHEMA.Columns AS b on a.Column_Name = b.Column_Name
Where a.TABLE_NAME = 'FY2006_DATA'
And b.TABLE_NAME = 'FY2007_DATA'
AND a.Column_Name IN
(Select Column_Name = LEFT(c.column_name, 20) FROM
[H1B_2006-2011].INFORMATION_SCHEMA.Columns AS c WHERE c.TABLE_NAME = 'FY2007_DATA' )
When I change "AND a.Column_Name IN.." to "AND a.Column_Name NOT IN.." so that the results will (should) display the extra columns in FY2007, in fact I do not see any results, but query executes perfect.
How can I achieve my goal.?
Thank you

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.

I have a .NET program that can connect to either an Access 97 database or anSQL Server 7 database. In the database I have two tables which have a fieldcalled ID. When I run a query like "SELECT A.*, B.* FROM A, B", the queryreturns those fields as "A.ID" and "B.ID" when connected to Access 97, butas "ID" and "ID" in SQL Server 7. Is there anyway to get SQL Server toprepend the table name to the field name in a case like this and not returnduplicate field names like that without having to specify aliases for thefields?- Don

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?

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.

productHeadings AS E2
WHERE B1.id = E1.parent_id
AND E1.id = E2.parent_id

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.

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.
