Arguments
objecttoken
Is either the object token of an OLE object that was previously created by using sp_OACreate or it is NULL. If objecttoken is specified, error information for that object is returned. If NULL is specified, the error information for the entire batch is returned.source OUTPUT
Is the source of the error information. If specified, it must be a local char, nchar, varchar, or nvarchar variable. The return value is truncated to fit the local variable if necessary.description OUTPUT
Is the description of the error. If specified, it must be a local char, nchar, varchar, or nvarchar variable. The return value is truncated to fit the local variable if necessary.helpfile OUTPUT
Is the help file for the OLE object. If specified, it must be a local char, nchar, varchar, or nvarchar variable. The return value is truncated to fit the local variable if necessary.helpid OUTPUT
Is the help file context ID. If specified, it must be a local int variable.[!UWAGA]
The parameters for this stored procedure are specified by position, not name.
Return Code Values
0 (success) or a nonzero number (failure) that is the integer value of the HRESULT returned by the OLE Automation object.
For more information about HRESULT Return Codes, see OLE Automation Return Codes and Error Information.
Result Sets
If no output parameters are specified, the error information is returned to the client as a result set.

Uwagi
Each call to an OLE Automation stored procedure (except sp_OAGetErrorInfo) resets the error information; therefore, sp_OAGetErrorInfo obtains error information only for the most recent OLE Automation stored procedure call. Note that because sp_OAGetErrorInfo does not reset the error information, it can be called multiple times to get the same error information.
The following table lists OLE Automation errors and their common causes.
Error and HRESULT |
Common cause |
|---|---|
Bad variable type (0x80020008) |
Data type of a Transact-SQL value passed as a method parameter did not match the Microsoft Visual Basic data type of the method parameter, or a NULL value was passed as a method parameter. |
Unknown name (0x8002006) |
Specified property or method name was not found for the specified object. |
Invalid class string (0x800401f3) |
Specified ProgID or CLSID is not registered as an OLE object on an instance of SQL Server. Custom OLE automation servers must be registered before they can be instantiated using sp_OACreate. This can be done by using the Regsvr32.exe utility for in-process (.dll) servers, or the /REGSERVER command-line switch for local (.exe) servers. |
Server execution failed (0x80080005) |
Specified OLE object is registered as a local OLE server (.exe file) but the .exe file could not be found or started. |
The specified module could not be found (0x8007007e) |
Specified OLE object is registered as an in-process OLE server (.dll file), but the .dll file could not be found or loaded. |
Type mismatch (0x80020005) |
Data type of a Transact-SQL local variable that is used to store a returned property value or a method return value did not match the Visual Basic data type of the property or method return value. Or, the return value of a property or a method was requested, but it does not return a value. |
Datatype or value of the 'context' parameter of sp_OACreate is invalid. (0x8004275B) |
The value of the context parameter should be one of: 1, 4, or 5. |

Examples
The following example displays OLE Automation error information.
DECLARE @output varchar(255)
DECLARE @hr int
DECLARE @source varchar(255)
DECLARE @description varchar(255)
PRINT 'OLE Automation Error Information'
EXEC @hr = sp_OAGetErrorInfo @object, @source OUT, @description OUT
IF @hr = 0
BEGIN
SELECT @output = ' Source: ' + @source
PRINT @output
SELECT @output = ' Description: ' + @description
PRINT @output
END
ELSE
BEGIN
PRINT ' sp_OAGetErrorInfo failed.'
RETURN
END
