Undocumented SQL Server 2000 System Tables




syscursors


Contains the attributes of a server cursor. This table is stored in the master database. The syscursors table is used by the sp_describe_cursor system stored procedure to report the attributes of a server cursor, and the sp_cursor_list system stored procedures to report the attributes of server cursors currently open for the connection.

Column name

Data type

Description

cursor_handle

int

A unique value for the cursor within the scope of the server.

cursor_name

sysname, nullable

Name of the cursor.

status

int

Same values as reported by the CURSOR_STATUS system function:

1 = The cursor referenced by the cursor name or variable is open. If the cursor is insensitive, static, or keyset, it has at least one row. If the cursor is dynamic, the result set has zero or more rows.

0 = The cursor referenced by the cursor name or variable is open but has no rows. Dynamic cursors never return this value.

-1 = The cursor referenced by the cursor name or variable is closed.

-2 = Applies only to cursor variables. There is no cursor assigned to the variable. Possibly, an OUTPUT parameter assigned a cursor to the variable, but the stored procedure closed the cursor before returning.

-3 = A cursor or cursor variable with the specified name does not exist, or the cursor variable has not had a cursor allocated to it.

model

tinyint

1 = Insensitive (or static)
2 = Keyset
3 = Dynamic
4 = Fast Forward

concurrency

tinyint

1 = Read-only
2 = Scroll locks
3 = Optimistic

scrollable

tinyint

0 = Forward-only
1 = Scrollable

open_status

tinyint

0 = Closed
1 = Open

cursor_rows

decimal(10,0)

Number of qualifying rows in the result set.

fetch_status

smallint

Status of the last fetch on this cursor.

0 = Fetch successful.

-1 = Fetch failed or is beyond the bounds of the cursor.

-2 = The requested row is missing.

-9 = There has been no fetch on the cursor.

column_count

smallint

Number of columns in the cursor result set.

row_count

decimal(10,0)

Number of rows affected by the last operation on the cursor.

last_operation

tinyint

Last operation performed on the cursor:

0 = No operations have been performed on the cursor.

1 = OPEN

2 = FETCH

3 = INSERT

4 = UPDATE

5 = DELETE

6 = CLOSE

7 = DEALLOCATE




syscursortables


Contains the base tables referenced by a server cursor. This table is stored in the master database. The syscursortables table is used by the sp_describe_cursor_tables system stored procedures to report the base tables referenced by a server cursor.

Column name

Data type

Description

cursor_handle

int

A unique value for the cursor within the scope of the server.

table owner

sysname, nullable

User ID of the table owner.

table_name

sysname, nullable

Name of the base table.

optimizer_hints

smallint

Bitmap consisting of one or more of:

1 = Row-level locking (ROWLOCK)

4 = Page-level locking (PAGELOCK)

8 = Table Lock (TABLOCK)

16 = Exclusive table lock (TABLOCKX)

32 = Update lock (UPDLOCK)

64 = No lock (NOLOCK)

128 = Fast first-row option (FASTFIRST)

4096 = Read repeatable semantic when used with declare cursor (HOLDLOCK)

lock_type

smallint

Scroll-lock type requested either explicitly or implicitly for each base table that underlies this cursor. The value can be:

0 = None

1 = Shared

3 = Update

server_name

sysname, nullable

Name of the linked server the table resides on. NULL if OPENQUERY or OPENROWSET are used.

objectid

int

Object ID of the table. 0 if OPENQUERY or OPENROWSET are used.

dbid

int

ID of the database the table resides in. 0 if OPENQUERY or OPENROWSET are used.

dbname

sysname, nullable

Name of the database the table resides in. NULL if OPENQUERY or OPENROWSET are used.
