EXCEL VBA ON ERROR ADO EXECUTE COMMAND ARCHIVE
( Note: Archive members have access to the webinar archive.)Įrror Handling refers to code that is written to handle errors which occur when your application is running. Members of the Webinar Archives can access the webinar for this article by clicking on the image below. Returns the error text from an error number. You can populate this when you use Err.Raise.Ī function that allows you to generate your own error. (Only useful if you need to check a specific error occurred.) When an error occurs the error information is stored here. Goes to a specific label when an error occurs. When error occurs, the code stops and displays the error.Ĭlears the current error setting and reverts to the default. 5.4 Runtime Errors that are not VBA Errors.5.3.1 Expected Versus Unexpected Errors.For example, if there were four (or more) parameters and you wanted to pass new values for only the first and fourth parameters, you would pass Array(var1,var4) as the Parameters argument. The order in which you specify the parameters is the same order in which the method passes them. You can override a subset of the parameters by omitting new values for some of the parameters when calling the Execute method.
If the query has parameters, the current values for the Command object's parameters are used unless you override these with parameter values passed with the Execute call. Some application languages allow you to ignore this return value if no Recordset is desired.Įxecute raises an error if the user specifies a value for CommandStream when the CommandType is adCmdStoredProc, adCmdTable, or adCmdTableDirect.
EXCEL VBA ON ERROR ADO EXECUTE COMMAND UPDATE
If the command is not intended to return results (for example, an SQL UPDATE query) the provider returns Nothing as long as the option adExecuteNoRecords is specified otherwise Execute returns a closed Recordset. The position of the stream on return from Execute is provider specific. If no stream was specified before calling Execute with adExecuteStream, an error occurs. An ADO Stream object can be specified to receive the results, or another stream object such as the IIS Response object can be specified. To obtain a binary stream, specify adExecuteStream in Options, then supply a stream by setting Command.Properties("Output Stream"). Results are returned in a Recordset (by default) or as a stream of binary information.
Using the Execute method on a Command object executes the query specified in the CommandText property or CommandStream property of the object. These values can only be used as options with the Open and Requery methods of a Recordset. Do not use the CommandTypeEnum values of adCmdFile or adCmdTableDirect with Execute. If adExecuteStream was specified, the options adAsyncFetch and adAsynchFetchNonBlocking are ignored. Use the ExecuteOptionEnum value adExecuteNoRecords to improve performance by minimizing internal processing. For example, you could use adCmdText and adExecuteNoRecords in combination if you want to have ADO evaluate the value of the CommandText property as text, and indicate that the command should discard and not return any records that might be generated when the command text executes. Can be a bitmask value made using CommandTypeEnum and/or ExecuteOptionEnum values. A Long value that indicates how the provider should evaluate the CommandText or the CommandStream property of the Command object. (Output parameters will not return correct values when passed in this argument.) A Variant array of parameter values used in conjunction with the input string or stream specified in CommandText or CommandStream. The Execute method will not return the correct information when used with adAsyncExecute, simply because when a command is executed asynchronously, the number of records affected may not yet be known at the time the method returns. To obtain this information, use the RecordCount property. RecordsAffected does not return the number of records returned by a result-returning query or stored procedure. The RecordsAffected parameter applies only for action queries or stored procedures. A Long variable to which the provider returns the number of records that the operation affected. Returns a Recordset object reference, a stream, or Nothing. Set recordset = command.Execute( RecordsAffected, Parameters, Options ) Executes the query, SQL statement, or stored procedure specified in the CommandText or CommandStream property of the Command object.
