Symptoms
In Microsoft SQL Server 2000 and in MicrosoftSQL Server 2005, you can add, delete, and rename the data files and the transaction log files. This article explains how to consolidate physical files, and how to rename the logical file name in SQL Server 2000 and in SQL Server 2005.
Resolution

Consolidate Physical Files You may have to consolidate files or reduce the number of physical files for a server that is running SQL Server 2000 or SQL Server 2005. To reduce the number of physical files, you can delete the files. To consolidate the files, you can purge inactive transactions.
Deleting FilesDeleting a data or a transaction log file removes the file from the database. However, you cannot remove a file from a database if the file contains data or transaction log information. You can only remove a file if the file is empty. If you have data that you want to keep, you can migrate the data from a data file to other files in the same filegroup. To migrate the data, you can use a DBCC SHRINKFILE statement and specify the EMPTYFILE clause. Then, SQL Server no longer allows data to be inserted in the file, and you can delete the file by using an ALTER DATABASE statement.
You cannot migrate the transaction log data from one log file to another to delete a transaction log file.
Purging Inactive TransactionsTo purge inactive transactions from a transaction log file, you must truncate or back up the transaction log. When a transaction log file no longer contains any active or inactive transactions, you can remove the log file from the database. To remove the log file from the database, use these steps: To shrink data or information in a file and to make the file empty, run the following Transact-SQL statement:

DBCC SHRINKFILE (‘<logical file name>’, EMPTYFILE ) To delete a file from a database, run the following Transact-SQL statement:

ALTER DATABASE <Database name>REMOVE FILE <logical file name>
IMPORTANT After you add or delete files, create a database backup immediately. You must create a full database backup before you create a transaction log backup.
Rename Logical File NameTo modify the logical name of a data file or a log file, specify the logical file name you want to rename by using the Name parameter, and then specify the new logical name for the file by using the NewName parameter. To rename the logical file, run the following Transact-SQL statement:

ALTER DATABASE <Database name>MODIFY FILE( NAME = <current_logical_name>, NEWNAME = <new_logical_name>)

Symptoms
Some data access objects in Visual Basic for Windows version 4.0 no longerhave the default “Name” property. Instead, these objects now have a defaultcollection. This change can lead to “Type Mismatch” (Error 13) or “InvalidArgument” (Error 3001) errors when attempting to run your code.
Resolution
To work around this problem, add the name of the property you want toreference.
For example, use this:

MsgBox Data1.Database.TableDefs(0).Name instead of this:

MsgBox Data1.Database.TablesDefs(0)

Symptoms
If you try to run Structured Query Language (SQL) against an Oracledatabase through Data Access Objects (DAO), you can encounter the followingerror:

Run-Time Error 3024
Couldn’t find file C:\Program Files\DevStudio\VB\<schema name>.mdb.This error occurs when you try to specify a schema name in your SQLstatement and you use DAO with Oracle. The <schema name> in the errormessage is whatever schema name you specified for the Oracle object youreference.
Resolution
If you add the dbSQLPassThrough option to the OpenRecordset method, thesample code in the MORE INFORMATION section of this article runs withouterror. You can use brackets ([ ]) around the table name in the SQL string toavoid the error as well:

sql = “SELECT * FROM [scott.emp]” Also, you can use an advanced data access technology, such as ActiveX DataObjects (ADO) to avoid this error.

Symptoms
When loading a form created by the Data Form Wizard, you may receive one ofthe following error messages:

Run-time error ‘-214217900 (80040e14)’, “Syntax error in FROM clause”
-or-

Run-time error ‘-214217904 (80040e10)’, “No value given for one or morerequired parameters”
Resolution
If the data source for a form created by the Data Form Wizard containsa dash ‘-’ in its name or in the name of a field, it is required that thedata source name or field name be delimited by brackets in a SQL statement.The Data Form Wizard does not include brackets around these names.

Symptoms
When you create a command object for Oracle to run a stored procedure by using the OracleCommand object from the Toolbox, you may receive the following error message after you specify the stored procedure name in the CommandText property:

Invalid Property Data
The stored procedure “OraclePackageName.OracleProcedureName” could not be found in the database.
Resolution
To work around this problem, use one of the following methods: In the CommandText property of OracleCommand1, type the name of the stored procedure exactly as it appears (this property is case-sensitive) in the stored procedure list in Server Explorer.Click OK to ignore the error message, and then manually add the code to call the Oracle stored procedure in your class. You can view the name of the stored procedure in Server Explorer. To do this, follow these steps: On the View menu, click Server Explorer.Right-click Data Connection, and then click Add Connection.On the Provider tab, click to select the Microsoft OLE DB Provider for Oracle check box. Click the Connection tab. Type the server name, the user name and the password, and then click Test Connection. Click OK to close the Test connection succeeded dialog box. Click OK to close the Data Link Properties dialog box. Expand Oracle database. Expand Stored Procedure to view the list of existing stored procedures.
