I remember once using a command in Query Analyser that gave me all the
information about a table. It showed details about the columns,
constraints, keys, indexes etc.
I can't remember how I did this? Can anyone help me?
It could of been a stored proc that I called or a query on the system
tables.
I do know that it was very simple to do and it was executed in Query
Analyser.
Can anyone help me?
Such as check all triggers that assign value to some columns ?
Thank you very much.
Hello,
I need to retrieve all the information about all the foreign key constraints,inorder to store them temporarily (to be deleted later)and then recreated after making the necessary modifications to the concerned tables.
The stored proc sp_helpconstraint shows all the constraint types, their user-defined or system-supplied name, the columns on which they have been defined, and the expression that defines them.But I don't know whether it can be manipulated to get what I want.I need to get it done programmatically..so that I can integrate it in my program which I'm building up progressively.
Any help or scripts would be appreciated!
Hi all. I have a SQL Server DB that i need to port out of SQL Server. I do not have a diagram illustrating the constraints in the construct of the tables. What is the best way to for me learn the relationships of the tables in sql server?
thanks for your help

I know this is probably a flick of a switch but I cannot figure out which switch. Setup is SQL Server / Stored Procedures / DAL / BLL(skipped for testing) / PL. The stored procedure queries from only one table and two columns are ignored because they are being phased out. I can run the stored procedure and preview the data in the DAL but when I create a page with an ODS linked to the DAL and a GridView I get this error. I checked every column that does not allow nulls and they all have values. I checked unique columns (ID is the only unique and is Identity=Yes in the table definition). I checked foreign-key columns for values that are not in the foreign table and there are none. Any ideas why do I get this?
Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
Hi,
I am getting the above error when trying to load a report into my Web Application, I have tracked the error down to one specific field in my database. Even though this field is a NVarChar field and is of size 30 it would seem that there is an issue returning the value from the field. I can write it into the database no problems but when I try to get it out of the database it returns the above error.
e.g
MOB 401.908.804 - Fails
0401.907.324 - okay
8239 9082 (pager) - fails
Anyone got an idea on how to fix this????
Regards..
Peter.
Can anyone recommend a good article/book on the subject? I am trying to find out more about compound primary keys. How many is “too many”? Does the number of primary key columns affect your performance? If so, how does it affect it? Should some of the constraints be handled from stored procedures?
Any response is greatly appreciated.

Hi,
I am new to MsSql. I want to know is there any command through which we can get all the consraints on a table or in a databases. In the same way how to get the all table names in a database from the coomand prompt or thorugh query analyzer.
Thanks
Hi all
Is there anyway you can deactivate/enable all constraints on a particular table so it can be done in a script?
Thanks.
I want to make a query, stored procedure, or whatever which will only display the primary key where there does no exist a foreign key in linked table.For example. If I had two tables with a one to many relationship.A [Computer] has one or more [Hard Drives]. I want to select only those computers which do not have a Hard Drive(s) associated with them. That is, show all computers where the Computer_ID field in the [Hard Drives] table does not exist. This seems simple but I'm drawing a blank here.

I believe there are sys tables that contain these but I'm not familiar with them any help would be appreciated.
This is an SQL Server 2000 question. Without having access to the "Design Table" option in the pop-up menu of a table, is there another way to see what constraints, indexes, primary key, etc. that a table has?
Thank you.
I'm trying to find a Stored procedure that will perform a complete table copy from the source to the target.
Anyone have one?
Hi,
I am DB programmer, How can i get Table Constraints to XML in SQL-Server 2000 with out data.
Just started learning SQL recently.But one thing i'm still not clear on is about altering relationships betweentables after they've been created.Instead of creating a foreign key when the table is first created - i createthe table and then run a query to set the foreign key and relationship(one-to-one, one-to-many etc)Anyways, long story short is i want to create a one-to-one relationship witha table but am having problems with adding more than one constraint at atime when altering a table.Understand yet? Easiest thing to do is show you:I have 2 tables: Branch_Table and Employee_TableI want to create a one-to-one relationship between emp_id on theBranch_Table and manager_id on the Employee_Table.The SQL i've written which doesn't seem to work is:ALTER TABLE Branch_TableAdd Constraint Branch_Table_FK1 FOREIGN KEY (manager_id)Add Constraint Branch_Table_UQ1 Unique (manager_id)References Employee_Table (emp_id));Am having trouble with that second Add constraint (UQ1 unique). I know it'ssomething to do with the Add syntax above.So basically, my question is can i create a one-to-one relationship withjust the one SQL Query? And how would i do it?Many thanks in advance.

Is it possible to define a constraint for Primary Key on more than 1 column or an alternate index on a column in a return table from an inline table valed function?
Example Header:
alter FUNCTION [dbo].[fntMetaFrame] (@ii_CompanyID int)
RETURNS @tbl_MetaFrame TABLE ( pk_Key int Identity(1,1) primary key,
ObjectID int ,
Seq int null )
I want the primary key to be pk_Key, ObjectID
OR
I want to add another index on ObjectID.
I need to script out data in several tables (30+) and then reload those tables on a different database. Â The "target" database table data will get overwritten each time, not appended to. Â Several of these tables have numerous foreign keys and other constraints that must be dealt with. Â None of them have more than 100 records or so. Â Then I need to keep this script in source control and reference it as part of a post-deployment step with a Visual Studio DB project.
I have redgate, dbghost and visual studio. Â Are there any tools will generate the script for me complete with dropping all the constraints, truncating the tables, then re-adding the constraints back? Â Or, am I looking at simply scripting the table data out, then modifying the script myself to add in the steps to drop/readd the constraints? Â Further, since some of these tables might have relationships, not just to other tables, but to those in question, there will likely be an order in which the tables need to get loaded.
The approach I am thinking will be needed, since ive done this sort of thing before except with SSIS, is to run something like dbghost or the "generate scripts" option in SSMS as a starting point. Â From there, change the order around as needed, etc. Â
I have removed all constraints of a table.I have a copy of the database as back up, now how can i add back the constraints to the removed table.

I am testing Insert, Update etc. and messing up my database with "dirty" data. Is there a way to temporarily drop FOREIGN KEY constraints to truncate a table after testing without dropping the whole table and rebuilding it?

Hey there,
Trying to build a temporary table based on a parent table such that:select * into #staging from tbl_parent where 1=0
The temp table (#staging) picks up any NOT NULL constraints from the parent (tbl_parent) table and frankly, it doesn't meet my needs.I also tried to build a view of the parent (tbl_parent) table from which to base my SELECT INTO and still, the constraints followed.
I'm thinking perhaps it possble to iterate though the temp table using syscolumns sysobjects and and set the column NULL properties on the temp table AFTER its been created but in this approach, I'm working to avoid directly referencing the columns by name.
Is this possible? A better answer perhaps?
Purpose of exercie is to populate a record in memory before it hits the table.I'll be constructing the record on the fly so that at first, I won't have all the fields to de-Null the columns.Also, I don't wish to lose the fact that some of my fields are Null - once I've fully populated my temp record, I'll insert into my 'real' table and will depend on constraints to throw the appropriate error. In this I won't have to built custom error checking in the stored procedure itself but instead depend on SQL SERVERS built capacity to the throw the error. This opens a bunch of possibilities for extensibility since if at a later date a constraint rule changes, one need only change the parent table definition rather than cracking open the stored procedure.
Thank you for reading and a big thanks to you for replying :)

Hi,
In my Sql Sever i have added one Database "Devtools", by restoring it from .bak file. Now In my asp page I want to Display a Datagrid with data from a table "Devices". I want to Generate the Gridview dynamically. The columns in the table are dynamic they are not constant so I want to generate my Gridview dynamically. So I want to get the columns info of the table and based on that I want to dynamically add the columns to the table. So how to get the info of the table first. Is there any query where i can get the table info
Hello:
I have an app that needs to retrieve the list of tables in an SQL database. I see that there is a way to do this with the OLEdb provider (GetOleDbSchemaTable() ), but I can't find a sibling method in SQL. IS there one/ Any Ideas?
Mike
In oracle there is a describe command:
describe table_name
This command will tell you the columns names, datatypes, and length of the columns for that particular table. Does anyone know if there is a simliar command in SQL server that would do that? The only way that I have found so far is to do a join of the syscolumns with sysobject by table name.
Okay, I'll admit it: I am not a Guru. Far from it. So here is one of the zillion tasks I cannot do - unfortunately it is one that I need to have done... :
I need a recordset containing the Name, Datatype, Size, Precision, and Name_of_parent_table of all columns in all non-system tables in a given database.
Most likely this can be accomplished with one or two SPs, but which ones? And how?
Is there any Kind Soul out there, perhaps?

i need help printing only certain rows from within a table.. for instance, if my table looks like this :
+-------------------+----------------+----------------------+
| Description | Heading | Link |
+-------------------+----------------+----------------------+
| Google | Heading 4 | www.google.com |
| Toms Hardware | Heading 3 | www.tomshardware.com |
| Anandtech | Heading 2 | www.anandtech.com |
| check this out | Heading 1 | www.henryadams.com |
| another heading 4 | Heading 4 | www.heading4.com |
| test | Heading 3 | www.test3.com |
| heading 4 agagin | Heading 4 | laksjdf;alkf |
| new heading test | newHeadingTest | www.newheadingtest |
+-------------------+----------------+----------------------+
and i want to only print out the results for "Heading 4" under the "Heading" column, and only have the results print out once, using php.. how would i do this?
The Headings are inputed by the user through a web interface i created where the user may either select an exisiting heading or type in a completely new one that has nothing to do with any of the others.
thanks for any and all of your help..
Hi,
Is it possible to retrieve column information alone in the sp_columns command? I saw that it has an additional option "@column_name". But when I include it in my sql, it doesn't work the way I had expected it to..
I had tried sp_columns @table_name='mytable', @column_name='COLUMN_NAME'
I expect just the column names alone in the resultset. What am I doing wrong here?
Thanks and Regards,
Celia.
Hi,
I have two tables - a stock table and a transaction table. The stock table is called stock and the transaction table is called trans. The table make a point of sale database. Both table have a joining field called prod_no.
I want to extract the stock line by querying stock.prod_no that are not present in the trans table for a period of time specified.
Basically, I want to find dead stock lines that have not been sold and, therefore, are not in the transaction table but that have a stock figure. I have to enter in a start and end date paramater using the ddate field in the trans table. I have looked at left, right and outer joins but with no luck and don't even know if this is the correct query type to use.
any help would be much appreciated,

I have a problem I am trying to ascertain the quality of the data in the table of a system we are migrating from one database to another.
We have already taken the step of converting it into SQL server to make sense of it now I wnat to query the data itself
To do this I set up a query that went through sysobjects and syclumns and listed the tables and their columns
What I want to do now is use this information to query the data elements themselves to determine where we should concentrate our data mapping on.
I started out with a cursor doing this
declare @table varchar(50)
declare @col varchar(50)
declare @result int
declare count_cursor cursor scroll
for select tname,cname from infotemp
open count_cursor
fetch from count_cursor
into @table,@col
while @@fetch_status=0
BEGIN
exec ('select count('+@col+') from '+@table)
Fetch next from count_cursor into @table,@col
END
close count_cursor
deallocate count_cursor
But I am having problems getting the counted value into the result value from the exec statement
Anybody got any ideas
Thanks
Hi,
How can I copy a database table with all its data, indexes and constraints to a new table in the same database in sql server 2005
