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.
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.
running sql server 2000 sp4, viewing the sysxlogins table data, and am wondering about the three items listed with a <NULL> in the name column, all xstatus = 192, each has a unique srvid value of 0, 2 or 3.
Looking in the MS tables reference book did not help they don't cover sysxlogins, googled around but no luck, searched this forum also.
I am getting this error: "Cannot insert the value NULL into column 'OrderID', table 'outman.outman.Contact'; column does not allow nulls. INSERT fails." -- But my value is not null. I did a response.write on it and it show the value. Of course, it would be nice if I could do a breakpoint but that doesn't seem to be working. I'll attach a couple of images below of my code, the error, and the breakpoint error.

We have a database where many tables have a field that has to be lengthened. In some cases this is a primary key or part of a primary key. The table in question is:-
/****** Object: Table [dbo].[DTb_HWSQueueMonthEnd] Script Date: 09/25/2014 14:05:09 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[DTb_HWSQueueMonthEnd](
[Code] ....
The script I am using is
DECLARE@Column varchar(100)--The name of the column to change DECLARE@size varchar(5)--The new size of the column DECLARE @TSQL varchar(255)--Contains the code to be executed DECLARE @Object varchar(50)--Holds the name of the table DECLARE @dropc varchar(255)-- Drop constraint script
[Code] ....
When I the the script I get the error message Could not create constraint. See previous errors.
Looking at the strings I build
ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] DROP CONSTRAINT PK_DTb_HWSQueueMonthEnd ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] Alter Column [Patient System Number] varchar(10) ALTER TABLE [dbo].[DTb_HWSQueueMonthEnd] ADD CONSTRAINT PK_DTb_HWSQueueMonthEnd PRIMARY KEY NONCLUSTERED ([Patient System Number] ASC,[Episode Number] ASC,[CensusDate] ASC) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
They all seem fine except the last one which returns the error
Msg 8111, Level 16, State 1, Line 1 Cannot define PRIMARY KEY constraint on nullable column in table 'DTb_HWSQueueMonthEnd'. Msg 1750, Level 16, State 0, Line 1 Could not create constraint. See previous errors.
None of the fields I try to create the key on are nullable.
I receive this message when I try to run any report. The reportserver and reportservertempdb databases were upgraded using backup/restore from SQL2000 to SQL2005 on a separate server which is running RS2005 . Please help. Thanks
Im trying to get the column names from a database and display them in textboxes. someone has already helped me by tellnig me that i need to use the FillSchema command. Which works just fine and I can see only the colum names in a datagrid when i bind it to that.
The problem is that I do not know how to extract the name of a column and put it in to a textbox ?
Hi,How do I display the column names from my Sql server table?In asp3 the recordset allowed thisforeach key in rs ColumnName = key.name ColumnValue = key.valuenextHow do I do this in .Net?I want to use a DataReader so I can read through each record and only display the ones I want.TABLE_ONEColumn_OneColumn_TwoColumn_Threethanks,
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.
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 all, By using below query i can get no of tables having the give column name in a particular database, SELECT COUNT(*) AS CounterFROM syscolumnsWHERE (name = 'empno') but i want to know the table names too? any one please suggest me how to find table names too...... In other words i know the particular column name and right now i want to know the table names in which this column name exists.
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:
Hi is possible to create dynamic column name example Declare @StartDate as dateTime Select @StartDate = '2004-06-05'
select SUM(Case When table1_date BETWEEN dateadd(day,-6,@StartDate) and @StartDate then 1 else 0 end)AS [dateadd(day,-6,@StartDate)], SUM(Case When table1_date BETWEEN dateadd(day,-13,@StartDate) and dateadd(day,-7,@StartDate) then 1 else 0 end)AS [dateadd(day,-13,@StartDate)] from table1
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.
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.
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?
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...
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.
