Greetings all,
I want to be able to generate a table on the fly. I know I can use dynamic sql to do this but my brains have forzen this afternoon so any help would be much appreciated.
I have the first query that returns one column with three rows. The contents of the these three rows will form the new columns in the dynamically generated table. How can I do this?
Thanks.
Hello,I am interested in dynamically creating temp tables using avariable in MS SQL Server 2000.For example:DECLARE @l_personsUID intselect @l_personsUID = 9842create table ##Test1table /*then the @l_personsUID */(resultset1 int)The key to the problem is that I want to use the variable@l_personsUID to name then temp table. The name of the temp tableshould be ##Test1table9842 not ##Test1table.Thanks for you help.Billy

Is it possible to creates fields of the table dynamically?. I have this situation in my project. This is just a small sample. I have row of length 140. I don't wan't to declare all this fields manually using the create table command.
The description of table is as, in this table all the field are of type varchar only, there are like 140 columns.
create dummy emp (
field1 VARCHAR(100), field2 varchar(200), field3 VARCHAR(100).... )
Table: Dummy
================================================== ==
field1 field2 field3..........
Empid Empname empaage1 sam 23...........
2 rai 22............
.
.
.
n raj 45.............
================================================== ==
Now I want to create another table as "EMP" , with proper data type
fields too..
create table emp (
empid int, empname varchar(100), empage int....)
The table should look like as:
Table: EMP
================================================== ==
Empid Empname empaage............
1 sam 23...............
2 rai 22................
.
.
.
n raj 45.................
================================================== ==
I want to do this dynamically.....
Some how I need to extract those field from table[dummy]; the first row acts as a column header for the table[Emp] and the subsequent row acts as a record for the table[Emp]
A small rough snippet of the code will be appreciated....
Waiting for replies........

Hello,
Quick question, I hope, I am trying to create a table that has a column that is a nested table in SQL Server 2005 Express Edition. Any ideas how I could go about doing this?

Hi all,
In my office computer network system (LAN), my Windows XP Pro PC has SQL Server Express and VB 2005 Express installed and I was granted to have the Administrator priviledge to access SQL Server Express. I tried to create a SQLCLR project in my terminal PC.
1) I tried to set up a remote connection to SQL Server Express in the following way: SQL Server EXpress => SQL Server Surface Area Configuration. In the Surface Area Configuration for Service and Connection - local, I clicked on Remote Connection of Database Engine, SQLEXPRESS and I had a "dot" on "Local and remote connections" and "Using TCP/IP only". Then I clicked on "Apply" and "OK" buttons. Then I went to restart my database engine in SQL Server Management. When I went to check SQL Server 2005 Surface Area Configuration, I saw the arrow is pointing to "Service", not to "Remote Connections"!!!??? Is it right/normal? Please comment on this matter and tell me how I can have "Remote Connecton" on after I selected it.
2) After I restarted the database engine (I guess!!), I executed the following project code (copied from a book) in my VB 2005 Express:

I am executing the Query shown below in Studio Management. I get the following error message:
Column ModifiedDate has an invalid data type on last line. I would also like to make agentname as primary key.
I have a function that returns a table from a comma-delimited string.
I want to take this a step further and create a function that will return a set of tablenames in a table based on a 'group' parameter which is a simple integer...1->9, etc.Obviously, what I am doing is not working out.

Hi - hope someone can help. We're creating a ASP.NET C# site that allows a user to connect to any of our 100+ SQL Servers and query a database that sits on every server. I'm trying to work out (and failing) how we can set the 'Data Source' in a connection string dynamically using the server name selected by the user in a drop down box. Any help appreciated, thanks in advance,

I'm investigating whether if its possible to Dynamically create a cube. Then Process this cube before exporting it to a .cub file.
I know that DTS in sqlserver is able to process a cube given at a scheduled time interval. But I'm not sure how I can export a cube to a offline .cub file dynamically. The only way that i know to create a .cub file is via PivotTable in Excel.
Any help in pointing me to the right direction is appreciated.
Thankyou :)

Hi everybody,
I have a problem. When I try to create a database with this code:
strConnection = "server=(local);Integrated Security=SSPI"
objConnection = New SqlConnection(strConnection)
objConnection.Open()
Dim strSQL = "CREATE DATABASE xxxxxx ON PRIMARY"
strSQL += "(Name=test_data, filename = 'xxxxx.mdf', size=3,"
strSQL += "maxsize=5, filegrowth=10%)log on"
strSQL += "(name=mydbb_log, filename='xxxxx.ldf',size=3,"
strSQL += "maxsize=20,filegrowth=1)"
objCommand = New SqlCommand(strSQL, objConnection)
objCommand.ExecuteNonQuery()
it usually works, except when the name of the database (xxxxxx) contains a number in the beginning of the name or if it is all made up completely by numbers. I also converted the database name into a string, but it doesn't work either.
What is the problem?
How can I solve it?
Thanks in advance
I was given what at first seemed a simple task (and maybe it is, but with everything else on my plate, I can't seem to get my head wrapped around this)...create a grid or table something similar to below:
Plan A Plan B PlanC PlanD
Item1 yes yes no no
Item2 yes yes no no
Item3 yes no yes no
etc.....
The "plans" are stored in one db table, the "items" in another. What I can't seem to get straight in my mind is how to relate the yess and nos and then generate a tabular layout similar to the above.
I don't need anyone to do it for me, but a push in the right direction would sure be nice (using SQL 2005) Thanks!
Hi
Some one Please guide me... How to create a Excel File Dynamically in DTS.

Folks,
Is there any way I can dynamically alter the structure of a table? In other words if my Transact SQL
statement returns 5 rows I want to alter an existing table and put in 5 columns. Strange?!
Something like
alter table add
column+@i
The alter table statement is within a Cursor and ideally @i should increment each time and alter
the table to put in a new column.
If I went 3 times thru the loop, I should have
column1
column2
column3
added to the new table.
Any pointers would be greatly appreciated. Thanks much in advance.
Has anyone found out how to dynamically create report width.
If I have 20 columns on a report all of 2cm, then report will be 40cm width.
If I display the columns based on specific criteria using the iif function and then setting the an expression for the Visibility Hidden property, the report could potentially reduce in width.
I cannot see how to build an expression for the report width or table width, to accommodate the potential change in the width of the report when columns are not shown, thus it pages incorrectly, leaving huge white space on the right of the report when columns are hidden... has anyone come across this requirement, and hopefully a solution for it?
Many Thanks people

View 4 Replies View RelatedTrying to figure out the best method of reading in a number of flat files, all with different number of columns and data types and outputting them to a database.
Here's the problem: They are EBCDIC encoded and some of the columns are packed decimal. I've set up one package that takes the flat file, unpacks the decimal (Using UnpackDecimal component) and then sending the rest through a second component to go from EBCDIC -> ASCII.
What I need is a way to do this for every flat file based on the schema for that flat file. One current solution is to write a script/app to create the .dtsx XML file and then execute that for each flat file. It appears like this may be possible, but I haven't gotten far enough to know for sure. So my questions are this:
1) Is there an easier way to do this (ie somehow feed the schema to the package and use it to dynamically set up the column makers and determine which columns get fed to the unpack decimal component.
2) If there isn't a better way, will dynamically creating the .dtsx XML file based on the necessary input/output columns for each flat file work? If so, what is a good source of information on this (information about how the .dtsx XML file is set up, what needs to be changed/what doesn't, etc).
Thanks,
Travis

Need to scheduled to copy table data from one database to another database daily @7:00 AM by creating the table with date and time stamp.
Example :
Test1DB ---> Table1
Test2DB -----> Table1_281120140700 in Day1 and Table2_291120140700 in Day2.....and so.
SELECT * INTO Test2db.dbo.new_table_name FROM Test1db.dbo.old_table_name in this format ??
script and scheduled to run daily @ 7:00AM?
I have three databases which have the identical data structure. When the user runs a report, he has to select a database.
For example, my report query would look like:
Select * from <theDatabase>.dbo.MyTable
How could I assign the value of <theDatabase> at run time depending on what the user selects from the list?
In my datasource, I have only specified the server name and no value for initial catalog.
If I run the following command in a Query window it works:
RESTORE DATABASE CIS_Source_Data_Test FROM DISK = 'y:CIS_Source_Data_backup_2015_06_17_085557_7782407.bak' WITH RECOVERY, REPLACE
If I dynamically put together the command and store it in variable @cmd and then execute it using
exec sp_executesql @cmd or exec (@cmd) it does not work. I get the following:
Msg 2745, Level 16, State 2, Procedure CIS_Source_Data_Refresh, Line 92
Process ID 62 has raised user error 50000, severity 20. SQL Server is terminating this process.
Msg 50000, Level 20, State 1, Procedure CIS_Source_Data_Refresh, Line 92
RESTORE DATABASE is terminating abnormally.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.
Why it won't work when I try to create and run it dynamically?
I am having 2 tables one is staging temp and another is main import table.
In my staging table there are 3 column Col001,Id,Loaddate

this function create a insert statement.
