Sp_columns Not Returnign Anything
Oct 13, 2006
Greetings all. I have a bizarre problem. I'm using sp columns to generate an html table with the field information of certain tables in my database. The table names are stored in an SQL Table called 'Manage_Tables' and I have 9 tables shown there. 6 out of the 9 are displaying correctly but the other 3 arent and the problem is coming from teh sp columns procedure that is returning nothing. why does this happen? all the tables are the same and have been created on teh same day by the same user with the rame rights and I have admin rights. Any clue?

Hi,
When I run sp_columns @table_name = someTable, I get many columns like TABLE_QUALIFIER, TABLE_OWNER and so on.
Is there a easy way to get only a COLUMN_NAME column?
Thanks

Hi friends,
I got troubles when I tried to pass table name to sp_columns via
@local_variable:
declare @tname as char(50)
set @tname = 'TB_MyTable'
exec sp_columns @tname
result of such script is:
TABLE_QUALIFIER ...[skipped]
-----------------------------------
(0 row(s) affected)
But if I will say:
exec sp_columns 'TB_MyTable'
result will be correct (all neccessary data about columns will be provided)
So, looks like if I pass table name which contains underscore via
@local_variable or SP parameter - result will be wrong.
If table name won't contains underscore - everything works fine and result
of script:
declare @tname as char(50)
set @tname = 'MyTable'
exec sp_columns @tname
will be absolutely correct.
Please, anybody can clarify this situation ???
Thanks in advance,
Michael

Hello,
I'm using sp_columns and would like to stock the result recordset into a variable (or simply get only the column name into a table variable in sql)
Is there any way to select only the column name and put it into a table variable ?
Thank

In SQL 2005, I'm getting very slow response times with sp_columns. It takes
around 8 seconds to return the results of calling sp_columns.
Any ideas?
Thanks

Hello,
I'm trying to use the "sp_columns" stored procedure to pull in some
information about a table in my db, but I'm continuing to get the same
error:
ERROR [42000] [Microsoft][ODBC SQL Server Driver][SQL Server]Procedure
'sp_columns' expects parameter '@table_name', which was not supplied.
I'm not sure why, but I've re-written my code several times and can't
figure out just why this error is happening. Here's a snippet of
the code:
Private Function GetDataType(ByVal columnName As String, ByVal table As String) As String
Dim con As New
OdbcConnection(ConfigurationSettings.AppSettings.Get("LiquorLiabilityConnection"))
Dim com As New OdbcCommand("sp_columns", con)
com.CommandType = CommandType.StoredProcedure
Dim param As New OdbcParameter("@table_name", table)
param.OdbcType = OdbcType.VarChar
com.Parameters.Add(param)
param = New OdbcParameter("@column_name", columnName)
param.OdbcType = OdbcType.VarChar
com.Parameters.Add(param)
Dim dr As OdbcDataReader
Dim name As String
con.Open()
dr = com.ExecuteReader() 'THIS TRIGGERS THE ERROR
While dr.Read
name = dr("TYPE_NAME")
End While
dr.Close()
con.Close()
Return name
End Function
Any suggestions would be appreciated.

I excute sp_columns in my Stored Procedure script to get the data type of a table column.
EXEC sp_columns @table_name = 'XXX', @column_name='YYY'
How do i store the column 'TYPE_NAME' in the return row into a variable so that i can use it later in my stored procedure?
Thanks
Hannah

Can anyone show me the syntax for exporting the result of sp_columns into a new table?
I've tried using "SELECT EXEC sp_columns...INTO 'column_info'" but I keep getting syntax errors that are unclear to me.
Any help would be greatly appreciated.

Some automated tools use sp_columns to find out the columns for a table, view or UDF that returns table.
In SQL Server 2000 it gives columns back but in SQL Server 2005 it does not, compat level set at 80 and 90.
Does anyone have an idea what id going on here?
Repro script below. I expect the script to return information about the two columns in the table defined in fnTestColumnsFromFunctions().
if exists (select 1
from sysobjects
where id = object_id('dbo.fnTestColumnsFromFunctions')
and type in ('IF', 'FN', 'TF'))
drop function dbo.fnTestColumnsFromFunctions;
go
create function dbo.fnTestColumnsFromFunctions()
returns @TestTable table
(
ttID int,
ttName varchar(50)
)
as
begin
return;
end
go
declare @dbname sysname;
declare @n int;
set @dbname = db_name();
exec @n = dbo.sp_columns
@table_name = 'fnTestColumnsFromFunctions',
@table_owner = 'dbo',
@table_qualifier = @dbname,
@column_name = null,
@ODBCVer = 2;
if exists (select 1
from sysobjects
where id = object_id('dbo.fnTestColumnsFromFunctions')
and type in ('IF', 'FN', 'TF'))
drop function dbo.fnTestColumnsFromFunctions;
go
