Is the name of the table used to return catalog information. name is sysname, with no default. Wildcard pattern matching is not supported.
[ @table_owner =] 'table_owner'
Is the table owner of the table used to return catalog information. owner is sysname, with a default of NULL. Wildcard pattern matching is not supported. If owner is not specified, the default table visibility rules of the underlying DBMS apply.
In SQL Server, if the current user owns a table with the specified name, the columns of that table are returned. If owner is not specified and the current user does not own a table of the specified name, this procedure looks for a table of the specified name owned by the database owner. If the table exists, its columns are returned.
[ @qualifier =] 'qualifier'
Is the name of the table qualifier. qualifier is sysname, with a default of NULL. Various DBMS products support three-part naming for tables (qualifier.owner.name). In SQL Server, this column represents the database name. In some products, it represents the server name of the database environment of the table.
[ @col_type =] 'col_type'
Is the column type. col_type is char(1), with a default of R. Type R returns the optimal column or set of columns that, by retrieving values from the column or columns, allows for any row in the specified table to be uniquely identified. A column can be either a pseudocolumn specifically designed for this purpose, or the column or columns of any unique index for the table. Type V returns the column or columns in the specified table, if any, that are automatically updated by the data source when any value in the row is updated by any transaction.
[ @scope =] 'scope'
Is the minimum required scope of the ROWID. scope is char(1), with a default of T. Scope C specifies that the ROWID is valid only when positioned on that row. Scope T specifies that the ROWID is valid for the transaction.
[ @nullable =] 'nullable'
Is whether the special columns can accept a null value. nullable is char(1), with a default of U. O specifies special columns that do not allow null values. U specifies columns that are partially nullable.
[ @ODBCVer =] 'ODBCVer'
Is the ODBC version being used. ODBCVer is int(4), with a default of 2. This indicates ODBC version 2.0. For more information about the difference between ODBC version 2.0 and ODBC version 3.0, see the ODBC SQLSpecialColumns specification for ODBC version 3.0.
Actual scope of the row ID. Can be 0, 1, or 2. SQL Server always returns 0. This field always returns a value.
0 = SQL_SCOPE_CURROW. The row ID is guaranteed to be valid only while positioned on that row. A later reselect using the row ID may not return a row if the row was updated or deleted by another transaction.
1 = SQL_SCOPE_TRANSACTION. The row ID is guaranteed to be valid for the duration of the current transaction.
2 = SQL_SCOPE_SESSION. The row ID is guaranteed to be valid for the duration of the session (across transaction boundaries).
Column name for each column of the tablereturned. This field always returns a value.
ODBC SQL data type.
Data source-dependent data type name; for example, char, varchar, money, or text.
Precision of the column on the data source. This field always returns a value.
Length, in bytes, required for the data type in its binary form in the data source, for example, 10 for char(10), 4 for integer, and 2 for smallint.
Scale of the column on the data source. NULL is returned for data types for which scale is not applicable.
Indicates whether the column is a pseudocolumn. SQL Server always returns 1:
