Retrieving Field Names from Temporary Tables in SQL Server 2008

To dynamically retrieve field names from temporary tables in SQL Server 2008, you can leverage the tempdb.sys.columns system table. This table provides metadata about the columns within all temporary tables in the tempdb database.

To query this information, execute the following SQL statement:

select * from tempdb.sys.columns where object_id =
object_id('tempdb..#mytemptable');

Replace #mytemptable with the name of your temporary table.

This query will return the following columns:

• column_id: Unique identifier for the column within the temporary table.
• object_id: Unique identifier for the table containing the column.
• name: Name of the column.
• system_type_id: Data type of the column.
• max_length: Maximum length of the column (for string or binary types).
• precision: Precision of the column (for numeric types).
• scale: Scale of the column (for numeric types).
• is_nullable: Whether the column allows null values or not.
• is_ansi_padded: Whether the column is ANSI padded or not.
• is_identity: Whether the column is an identity column or not.
• is_computed: Whether the column is a computed column or not.

By examining the name column, you can retrieve the list of field names for your temporary table.
