I have two questions:
1. Which system table (data dictionary) I can select to get all table names in one database?
2. What sql command can I use to get a definition about a table?
Thanks
Hello,
I have ran into a problem when i'm getting table names in c#.
I have tried the sql command:
select name from sysobjects where type='U' order by name
So it returns the names without a problem. But when I try to access to some tables using their names (to retrieve the columns) I sometimes get the error "Invalid object name" following by the name of the table.
So I realized the if the table was not under dbo user then i would get this error.
for example: "select name from ContactCreditCard"
gives me error because in database management tool it is shown like this: Sales.ContactCreditCard
How can i fix this problem? How to get that prefix of the tables?
Thank you,
I have a database and I want to retrieve informations about all tables
defined in this database. In other words I need the table list defined in
database. Can you help me?
Thank you.
How to get the list of table names in a SQL2005 database?
View 6 Replies View RelatedCan anybody tell me how to find out whether a particular column exists in any of the tables of a database and if it does, display the table names?
Thanks
In the past, we had table names such as:
PurchaseOrders
SalesOrders
Now with SQL 2005, you can use schema namespaces, so it could become:
Purchasing.Orders
Sales.Orders
So essentially you can use exactly the SAME table names, in different schemas.
So... would you recommend to change to the last model, or just stay with the old way?
What is best practice?
One of the reasons why I ask this question is that I looked at the AdventureWorks sample database included with SQL Server 2005, and Microsoft is using:
Sales.SalesOrderDetail
Purchasing.PurchaseOrderDetail
etc...
Why not:
Sales.OrderDetail
Purchasing.OrderDetail
etc...

Hi there,
I am trying to create a list of all the tables in one database and then list the size of each table. So for example I want to create a table with the table name and table size for one DB
E.g
Table1 1111KB
Table2 123300MB
Table3 120448KB
etc for all the tables in a particukar DB
I know there is a stored procedure to list the sizes: 'sp_spaceused' but not sure how to script all this together.
can anyone help please!!

View 2 Replies View RelatedI am designing a package to export staging tables into a flat file.The names of the tables will be: TableAStaging_YYYYMM and TableBStaging_YYYYMM. As you can see the names of the tables will be changing each month.
The flat files will have similar naming: C:MyPathFlatFileTableAStaging__YYYYMM and C:MyPathFlatFileTableAStaging__YYYYMM.I want to run the package as an sql job in two steps, one for each table.I need to dynamically pass the table names and file names (together with the path) to the IS package.
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.
The database has approx. 2500 temporary tables. The temp tables match a pattern such as APTMP... I tried deleting the tables in SSMS with the statement, Delete from Information_Schema.tables where substring(table_name,1,5) = 'APTMP' This returns the error message"Ad hoc updates to system catalogs are not allowed".
What is the correct way to delete a group of tables whose name match a pattern from within SSMS?
I'm trying to do an update query that looks like this:
UPDATE
PAEMPLOYEE
SET PAEMPLOYEE.LOCAT_CODE = EMPLOYEE.PROCESS_LEVEL
FROM
PAEMPLOYEE A
JOIN EMPLOYEE B ON A.EMPLOYEE = B.EMPLOYEE
It's erroring out on the Employee prefix B.EMPLOYEE saying:
..."does not match with a table name or alias name used in the query"
Is it wrong or will it cause problems to have a field name the same as the table name?
Hello,
Maybe anyone have done that before?
I have table where i store SOURCE_TABLE_NAME and DESTINATION_TABLE_NAME, there is about 120+ tables.
i need make SSIS package which selects SOURCE_TABLE_NAME from source ole db, and loads it to DESTINATION_TABLE_NAME in destination ole db.
I made such SSIS package. set ole db source data access mode to table or view name variable.
set ole db destination data access mode to table or view name variable. set to variables defoult values (names of existing tables)
but when i loop table names is changed, it reports error, that can map columns, becouse in new tables is different columns.
how to solve that problem?
How do I use table names stored in variables in stored procedures?
Code Snippetif (select count(*) from @tablename) = 0 or (select count(*) from @tablename) = 1000000
I receive the error 'must declare table variable '@tablename''
I've looked into table variables and they are not what I would require to accomplish what is needed.
After browsing through the forums I believe I need to use dynamic sql particuarly involving sp_executesql. However, I am pretty new at sql and do not really understand how to use this and receive an output parameter from it(msdn kind of confuses me too). I am tryin got receive an integer count of the records from a certain table which can change to anything depending on what the user requires.
Code Snippet
if exists(Select * from sysobjects where name = @temptablename)
drop table @temptablename
It does not like the 'drop table @temptablename' part here. This probably wouldn't be an issue if I could get temporary tables to work, however when I use temporary tables i get invalid object '#temptable'.
Heres what the stored procedure does.
I duplicate a table that is going to be modified by using 'select into temptable'
I add the records required using 'Insert into temptable(Columns) Select(Columns)f rom TableA'
then I truncate the original table that is being modified and insert the temporary table into the original.
Heres the actual SQL query that produces the temporary table error.
Code Snippet
Select * into #temptableabcd from TableA
Insert into #temptableabcd(ColumnA, ColumnB,Field_01, Field_02)
SELECT ColumnA, ColumnB, Sum(ABC_01) as 'Field_01', Sum(ABC_02) as 'Field_02',
FROM TableB
where ColumnB = 003860
Group By ColumnA, ColumnB
TRUNCATE TABLE TableA
Insert into TableA(ColumnA, ColumnB,Field_01, Field_02)
Select ColumnA, ColumnB, Sum(Field_01) as 'Field_01', Sum('Field_02) as 'Field_02',
From #temptableabcd
Group by ColumnA, ColumnB
The above coding produces
Msg 208, Level 16, State 0, Line 1
Invalid object name '#temptableabcd'.
Why does this seem to work when I use an actual table? With an actual table the SQL runs smoothly, however that creates the table names as a variable problem from above. Is there certain limitation with temporary tables in stored procedures? How would I get the temporary table to work in this case if possible?
Thanks for the help.
I have a function that returns a table from a comma-delimited string.

Hello,
It is possible to write stored procedures which take table names as parameters; is it also possible to do this with table valued functions?
For example, a simple stored procedure is this:
CREATE PROCEDURE SelectTop(@tableName sysname)
AS
BEGIN
Execute('Select top 10 * from ' + @tableName + ';')
END
I want to be able to do the analogous thing with a table valued function (so that I can query the result set, without having to create a temp table). How should I do this (i.e., pass a tablename as an argument to a table valued function)?
Hi there. I haven't been able to figure out how to join a table on column on multiple table names. Here's the situation:
I have a table "tblJob" with a key of jobID. Now for every jobID, the program creates a new table that keeps track of the stock before the jobId was processed and after it was processed to give accurate stock levels and show the difference in stock levels. So, a jobID of 355 would be related to the table: "tblPreStock_335" and "tblPostStock_335". These 2 tables have all the materials in stock and the quantity. Therefore they show how much material was used. I need to figure out the difference in the material in the stock before and after the processing.
That means that I have to get a stockID, get the associated pre and post tables, and then display the difference of ALL the materials in the pre and post tables.
Could someone help me get started on the right path? Even a link to similiar problem that I haven't found would be nice.
Thx
Oracle provides for a table to have an alias name.
Does SQL Server 7 support alias names for tables?
Thanks!!
I like to print the table names that starts with 'table'.
I'm getting the same table name four times. Instead of four different table name.

select 17, 'tableDaniel' union all
select 18, 'tableRon' union all
select 19, 'tableKen' union all
select 10, 'tableHonda'
declare @string varchar(330)
declare @tableName varchar(30)
declare @count int
set @count = 0
while (@count < 5)
begin
select @tableName = table_name from information_schema.tables
where table_name like 'table%'
exec(@string)
print @tablename
set @count = @count + 1
end
In SQL Server Management Studio when browsing the tables they are all prefixed with dbo followed by the table name. Is there a way of turning this off.
Thanks
just starting with sql server, thru the sql express edition, before i get to far wondering if it is ok to use the same database names, specifically the ASPNetDB.mdf in different web applications, or will this cause problems down the line,
ie will have different web site applications running on IIS and want to use the aspnet_regsl wizard,
also wondering if this has any implicaitons when publishing web application to web servers, are any of the local sql express server settings passed on to the web host provider, read about machine.config and if i understand i should put all the settings in the web.config file via the VS20005 ide.
also will it cause any problem inside the sql express magement console,

While setting up a BCP in a DTS package, I've found a rather annoying 'feature' in DTS. When selecting the destination table, the display does not provide enough spaces to see the full table name. It is a drop down with a set width, and the database and owner are displayed with the table name. I hadn't noticed this problem in the past, but the database I'm working with now has several tables that start with the same letters, and when the drop down displays them, they all look the same.
Does anyone know of a work around for this so that I can see the full table names? Even being able to see them after the package is created would be nice, because then I could check to see if I guessed the correct table.
Thanks

Using VB5|6/ADO/MSSQL6.5. I want to get the names of tables in a query. I.e. if query is "Select Name, Title from Employee inner join job on employee.empid = job.empid" I want a way to get "Name, Title"
In VB 3 we used the VBSQL.VBX which had 2 functions for this: SQLTabCount and SQLTabName.
Thanks in advance

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.

View 2 Replies View Relatedhere a quick rundown of what i want to do:

database1
database hold all my good information.
database 2 is the copy for breaking.
Im too a point that i need to get my 2nd DB to by like the first.
I want to truncate all the tables in database2, and then export, or select from insert into.
I just need the data, not triggers or anything like that.
So:
How can i find the name of my tables (not views) in that database
For each (select table_name from system where database="database") copy database.table_name database1.table_name;
i hope that makes sense.
I just need to restore my devel DB back to the original so i can mess it up again,

I have a cursor which populates a variable with the name of each user table within my DB.
I'm trying to copy the tables one at a time by using a command like this:
SELECT * INTO @NewTable FROM @OrigTable
Query analyzer tells me that there's incorrect syntax near the keyword 'INTO'.
This seems fair enough to me as I assume it's trying to put the data into the variable rather than the table name which is held within the variable. Does any know how I can get around this?
Are there any alternative ways of copying the table structure (preferable without the data)?
BTW both variables are of type char(100)
In a stored procedure returning several tables how can I assign a name to each table.
I wish to select the table in my app using DataSet.Tables("MyTable") rather than DataSet.Tables(0)
Create Procedure myProc As
Select * from table1
Select * from table2
Select * from table3
