sp_cursorexecute (Transact-SQL)

Creates and populates a cursor based upon the execution plan created by sp_cursorprepare. This procedure, coupled with sp_cursorprepare, has the same function as sp_cursoropen, but is split into two phases. sp_cursorexecute is invoked by specifying ID =4 in a tabular data stream (TDS) packet.

Transact-SQL Syntax Conventions

Syntax

sp_cursorexecute prepared_handle, cursor 
    [ , scrollopt [ OUTPUT ]
    [ , ccopt [ OUTPUT ]
    [ ,rowcount OUTPUT [ ,bound param] [,...n] ] ] ] ] 

Arguments

• prepared_handle
  Is the prepared statement handle value returned by sp_cursorprepare. prepared_handle is a required parameter that calls for an int input value.

• cursor
  Is the SQL Server-generated cursor identifier. cursor is a required parameter that must be supplied on all subsequent procedures which act upon the cursor, such as sp_cursorfetch

• scrollopt
  Scroll option. scrollopt is an optional parameter that requires an int input value. The sp_cursorexecute scrollopt parameter has the same value options as those for sp_cursoropen.

  Note

  The PARAMETERIZED_STMT value is not supported.

  Important

  If a scrollopt value is not specified, the default value is KEYSET regardless of scrollopt value specified in sp_cursorprepare.

• ccopt
  Currency control option. ccopt is an optional parameter that requires an int input value. The sp_cursorexecute ccopt parameter has the same value options as those for sp_cursoropen.

  Important

  If a ccopt value is not specified, the default value is OPTIMISTIC regardless of ccopt value specified in sp_cursorprepare.

• rowcount
  Is an optional parameter that signifies the number of fetch buffer rows to use with AUTO_FETCH. The default is 20 rows. rowcount behaves differently when assigned as an input value versus a return value.

  As input value	As return value
  When AUTO_FETCH is specified with FAST_FORWARD cursors rowcount represents the number of rows to place into the fetch buffer.	Represents the number of rows in the result set. When the scrollopt AUTO_FETCH value is specified, rowcount returns the number of rows that were fetched into the fetch buffer.

• bound_param
  Signifies the optional use of additional parameters.

  Note

  Any parameters after the fifth are passed along to the statement plan as input parameters.

Code Return Value

rowcount may return the following values.

Value	Description
-1	Number of rows unknown.
-n	An asynchronous population is in effect.

Remarks

scrollopt and ccopt Parameters

scrollopt and ccopt are useful when the cached plans are preempted for the server cache, meaning that the prepared handle identifying the statement must be recompiled. The scrollopt and ccopt parameter values must match the values sent in the original request to sp_cursorprepare.

Note

PARAMETERIZED_STMT should not be assigned to scrollopt.

Failure to provide matching values will result in recompilation of the plans, negating the prepare and execute operations.

RPC and TDS considerations

The RPC RETURN_METADATA input flag can be set to 1 to request that cursor select list metadata be returned in the TDS stream.
