Hi,

I am trying to create a dynamic SQL statment by passing in values from variables. For example:

declare @field1 varchar(10)
declare @field1 varchar(10)
declare @cmd varchar(1000)

Set @field1 = 'South Pole'
Set @field2 = 'Winter'

-- An exmaple of a SQL statement to be created is :
Select 'South Pole','Winter', count(*) from Penguines, ##tmp1 where Penguines.type = ##tmp1.type

-- Please note that the above is not a real example. The key is how do I get the values South Pole and Winter inside of single quotes
so that the constructed value od @cmd is the same as given in the above example.

Set @cmd = 'Select ' + How do I proceed after this? I tried different combinations of single an ddouble quotes, but SQL Server is not liking it.

Thanks for your help in advance!

Select ''South Pole'',''Winter'', count(*) from Penguines, ##tmp1 where Penguines.type = ##tmp1.type

or

Set @cmd ='Select '''+@field1+''','+@field2+'',' count(*) from Penguines, ##tmp1 where Penguines.type = ##tmp1.type'

Note that i didnt test second example

[code]Set @cmd = 'Select ''' + @filed1 + ''', ''' + @field2 + ''',' count(*) from Penguines, ##tmp1 where Penguines.type = ##tmp1.type'[/code]

specify 2 double quote for each single quote inside the quoted string

Thanks for all the response Guys.

I just had to make one change :

Set @cmd = ' select ''' +@field1 +''',''' + @field2 +''', count(*)
from Penguines, ##tmp1 where Penguines.type = ##tmp1.type'

Removed the quote before the count(*)
