sp_cursorprepare (Transact-SQL)

THIS TOPIC APPLIES TO:yesSQL Server (starting with 2008)noAzure SQL DatabasenoAzure SQL Data Warehouse noParallel Data Warehouse

Compiles the cursor statement or batch into an execution plan, but does not create the cursor. The compiled statement can later be used by sp_cursorexecute. This procedure, coupled with sp_cursorexecute, has the same function as sp_cursoropen, but is split into two phases. sp_cursorprepare is invoked by specifying ID = 3 in a tabular data stream (TDS) packet.

Syntax


sp_cursorprepare prepared_handle OUTPUT, params , stmt , options  
    [ , scrollopt[ , ccopt]]  

Arguments

prepared_handle
A SQL Server-generated prepared handle identifier that returns an integer value.

Note

prepared_handle is subsequently supplied to a sp_cursorexecute procedure in order to open a cursor. Once a handle is created, it exists until you log off or until you explicitly remove it through a sp_cursorunprepare procedure.

params
Identifies parameterized statements. The params definition of variables is substituted for parameter markers in the statement. params is a required parameter that calls for an ntext, nchar, or nvarchar input value. Input a NULL value if the statement is not parameterized.

Note

Use an ntext string as the input value when stmt is parameterized and the scrollopt PARAMETERIZED_STMT value is ON.

stmt
Defines the cursor result set. The stmt parameter is required and calls for an ntext, nchar or nvarchar input value.

Note

The rules for specifying the stmt value are the same as those for sp_cursoropen, with the exception that the stmt string data type must be ntext.

options
An optional parameter that returns a description of the cursor result set columns. options requires the following int input value.

Value Description
0x0001 RETURN_METADATA

scrollopt
Scroll Option. scrollopt is an optional parameter that requires one of the following int input values.

Value Description
0x0001 KEYSET
0x0002 DYNAMIC
0x0004 FORWARD_ONLY
0x0008 STATIC
0x10 FAST_FORWARD
0x1000 PARAMETERIZED_STMT
0x2000 AUTO_FETCH
0x4000 AUTO_CLOSE
0x8000 CHECK_ACCEPTED_TYPES
0x10000 KEYSET_ACCEPTABLE
0x20000 DYNAMIC_ACCEPTABLE
0x40000 FORWARD_ONLY_ACCEPTABLE
0x80000 STATIC_ACCEPTABLE
0x100000 FAST_FORWARD_ACCEPTABLE

Because the requested value might not be appropriate for the cursor defined by stmt, this parameter serves as both input and output. In such cases, SQL Server assigns an appropriate value.

ccopt
Concurrency control option. ccopt is an optional parameter that requires one of the following int input values.

Value Description
0x0001 READ_ONLY
0x0002 SCROLL_LOCKS (previously known as LOCKCC)
0x0004 OPTIMISTIC (previously known as OPTCC)
0x0008 OPTIMISTIC (previously known as OPTCCVAL)
0x2000 ALLOW_DIRECT
0x4000 UPDT_IN_PLACE
0x8000 CHECK_ACCEPTED_OPTS
0x10000 READ_ONLY_ACCEPTABLE
0x20000 SCROLL_LOCKS_ACCEPTABLE
0x40000 OPTIMISTIC_ACCEPTABLE
0x80000 OPTIMISITC_ACCEPTABLE

As with scrollpt, SQL Server can assign a different value from the one requested.

Remarks

The RPC status parameter is one of the following:

Value Description
0 Success
0x0001 Failure
1FF6 Could not return metadata.

Note: The reason for this is that the statement does not produce a result set; for example, it is an INSERT or DDL statement.

Examples

When stmt is parameterized and the scrollopt PARAMETERIZED_STMT value is ON, the format of the string is as follows:

{ <local variable name><data type> } [ ,…n ]
