Does anyone have any words of advice/code snippets etc etc on how to dynaically create insert statements e.g with a list of tables names that I feed into information_schema.columns can I generate the header for an insert statement so I can add the "select * from blah" into it using a sql str

many thanks

At my shop we use SQL Scripter because it is free and works really well for creating insert statements.

in 2005

in the object tree

- right click the table

- select script as

- select INSERT to

- select your prefered output

I'm sure theres something similar in 2000

If thats not what you're after then can you repost the problem a bit more descriptively

(apologies if that seems a bit obtuse, I'm in hard of understanding mode today)

Now keeping in mind that dynamic SQL can be very dangerous when you use it around GUI system (SQL injection ,etc....) You could try something like this



Declare @myTable sysname

declare @columnnames as varchar(max)

Select @mytable='testpivot',   --my table name - change as appropriate

          @columnnames='['

Select @columnnames=@columnnames+sc.name+'],['

from sys.all_columns sc

where sc.object_id=object_ID(@mytable)

ORDER BY column_id

select @columnnames=left(@columnnames,len(@columnnames)-2)  --get rid of the open bracket at the end

select @columnnames

Your lack of planning does not constitute an emergency on my part...unless you're my manager...or a director and above...or a really loud-spoken end-user..All right - what was my emergency again?

You could also use information_schema.columns (something I learned about on this site). Using blatent plagerism of Mr. Matt Miller's response:



Declare @myTable sysname

declare @columnnames as varchar(max)

Select @mytable='YourTableName',

       @columnnames='['

Select @columnnames=@columnnames+sc.Column_Name+'],['

from information_schema.columns sc

where Table_Name = @myTable

ORDER BY Ordinal_Position

select @columnnames=left(@columnnames,len(@columnnames)-2)  --get rid of the open bracket at the end

select @columnnames

I do this sort of thing all the time. I ended up writing a function passing it the table name and which columns to omit (those being identity, computed, time stamp, and values that would be substituted in the select statement).

The function would build the string of columns that could be used in both the insert and select statements. The code you have searching syscolumns should work fine in the function.

This can be very useful in a system that has tables with many columns in each table and you don't have to hand code all of them. I use it mostly for cloning rows where most of the values in the clone record are appropriate for the output record.
