How to find invalid objects in a SQL Server database

Last modified: March 28, 2025

SQL Complete makes it easy to find invalid objects in multiple databases using a GUI interface or the command line. This feature helps to learn if any objects reference other objects that no longer exist.

How to find invalid objects in a database

1. Open the Find Invalid Objects grid by using one of the following ways:

On the ribbon, select SQL Complete > Find Invalid Objects.
In Object Explorer, right-click the required database and select SQL Complete > Find Invalid Objects.
Press Ctrl + Alt + F.

2. Specify the connection and select the databases to search for invalid objects.

3. Click Analyze to start searching.

How to manage invalid objects

Invalid objects are listed in a grid showing the type of database object, the schema it belongs to, its name, and why it is deemed invalid. The preview pane displays the SQL script generated for the invalid object and highlights the object that caused the selected object to be invalid.

Note

Searching for invalid objects is not supported on Azure SQL servers.

In the Find Invalid Objects grid, you can perform the following tasks:

Select the invalid objects to view the SQL script generated for the object at the bottom preview pane.
Right-click the invalid object and select on the shortcut menu:
- Clear All to remove all invalid objects from the grid.
- Find in Object Explorer to locate the selected invalid object in Object Explorer.
- Export to CSV to store data of all invalid objects as a grid in the CSV file. The grid contains the information available in the Find Invalid Objects grid.
Generate the ALTER and DROP scripts for the selected invalid objects to a new SQL document or to the clipboard.
Create a .bat file to automate searching invalid objects from the command line.

How to export invalid objects to a file

1. Find invalid objects in the required database.

2. In the Find Invalid Objects grid, right-click the objects and select Export to CSV.

Generate the ALTER and DROP scripts

3. In the Save As window that opens, specify the file name and path to save the file, and click Save.

The file will contain all invalid objects exported from the Find Invalid Objects grid:

How to script out the object

1. In the Find Invalid Objects grid, select the checkbox next to the required object.

2. On the toolbar, click Script as ALTER to generate the ALTER script for the object or Script as DROP to generate the DROP script for the object.

Note

To copy the script to the clipboard, click the down arrow next to Script as ALTER or Script as DROP and select To Clipboard.

Script as ALTER

3. By default, the script will open in a new SQL document.

How to create a .bat file

SQL Complete has a built-in Command Line Wizard that converts the search options for invalid objects into command-line syntax and saves it as a *.bat file. You can then use this .bat file with a script and Windows Task Scheduler or any other task scheduler tool to schedule the search for invalid objects.

To open the Command Line Wizard, click Save Command Line on the toolbar.

Options of the Command Line Wizard

The command line wizard has the following options:

Option	Description
Connection	Specify the connection string for the database to search for invalid objects.
Password	Specify the server password. Note that it will override the values specified in the `Connection` parameter.
Database	Specify the database to find invalid objects. You can specify either a single database or multiple databases separated by commas. Note that it will override the database specified in the `Connection` parameter.
All databases	Select this option if you want to search for invalid objects in all non-system databases located on the server.
Report	Specify a path to the report that will be generated in the CSV file format.
Log	Specify a path to a log file.
Echo OFF	Select this option to enclose all the text in the bat file in the @Echo OFF … @Echo ON construct. This will turn off the display of the commands being entered on the screen.
Keep opened	Select this option to place the pause command at the end of the bat file text. This will leave the command window open.
PowerShell	Select this option to generate the `&` symbol at the beginning of the bat file text. This will ensure the PowerShell compatibility.

You can click Validate to verify the script.

How to find invalid objects in a database from the command line

You can automate the search for invalid objects in a database using the following script from the command line:

sqlcomplete.com /findinvalidobjects [/option_name1[:value | [parameter1:value parameter2:value ..]] /option_name2 ..]

Command line usage

Argument	Action and usage
`/findinvalidobjects`	Finds any objects referencing other objects that were dropped and no longer exist in the database.
`/connection`	Usage: `/connection:<connection_string>`Specifies the connection string.
`/password`	Usage: `/password:<password>`Specifies the server password and overrides the values specified in the `/connection` parameter.
`/database`	Usage: `/database:<dbname1[,dbname2]>`Specifies the database(s) and overrides the values specified in the `/connection` parameter. You can specify either a single database or multiple databases separated by commas.
`/alldatabases`	Usage: `/alldatabases`Finds invalid objects for all non-system databases specified in the /connection parameter.
`/exitcodes`	Usage: `/exitcodes`Displays the list of exit codes that the command-line operation can return.
`/log`	Usage: `/log:<filepath>`Generates a log file and saves it to the specified folder.
`/report`	Usage: `/report:<filename>`Generates a report in the CSV file format.
`/treatwarningaserror`	Usage: `/treatWarningAsError:[Yes\|No]` Specifies the behavior for treating warnings. Yes: Treat all warnings as errors. The errormode option will determine the subsequent behavior. No: Do not consider warnings to be errors and continue the command line execution.
`/errormode`	Usage: `/errormode:<ignore\|abort>`Specifies the application behavior when encountering an error:Ignore: Ignore all errors and continue execution.Abort: Cancel execution if an error occurs.

Exit codes used in the command line

An exit code is a status code that a command-line script returns. It indicates whether the execution was successful or if an error occurred. When a user runs the /findinvalidobjects command, the script may return the following exit codes:

Exit code	Description	Additional information
0	Success	The operation has been completed without errors.
1	Unhandled exception	Unhandled exception. See the log for more details.
10	Command line usage error	The command line was used incorrectly. For example, an incorrect flag or incorrect syntax may have been used.
11	Illegal argument duplication	Some arguments may not appear in a command line more than once. For example, `/arg2` depends on `/arg1` but you have specified `/arg2` without specifying `/arg1`, or `/arg2` cannot be used with `/arg1`, but you have used them both.
20	Trial expired	Software trial period has expired, or the product has not been activated.
40	Server connection fail	Server connection failed.
104	High-level parser error	High-level errors were encountered while parsing a scripts folder.
105	Resource unavailable	The file is missing.

Worked example: How to find invalid objects and create a CSV report

Let us find invalid objects in the AdventureWorks2022 database on the demo-mssql\SQLEXPRESS server and generate a report in the CSV file format.

To find invalid objects:

1. Open the Command Prompt or terminal and navigate to the installation folder of dbForge SQL Complete. For this, you can use the cd command. The default installation folder is C:\Program Files (x86)\Devart\dbForge SQL Complete.

2. Enter the following command:

sqlcomplete.com /findinvalidobjects /connection:"Data Source=demo-mssql\SQLEXPRESS; Integrated Security=False; User ID=yourUsername"; /database:AdventureWorks2022 /log:"D:\logfile.txt" /report:"D:\report.csv"

where:

AdventureWorks2022 is a name of the database whose invalid objects you want to find.
D:\logfile.txt is a path to the log file the operation will create after completion.
D:\report.csv is a path to the report file the operation will generate after completion.

3. Press Enter to execute the command.

The command outputs a table with invalid objects and generates a log and report files.

Troubleshooting

You may face the following error while looking for invalid objects in databases with more than 5,000 objects:

Could not find a part of the path 'C:\Users\User1\AppData\Local\Temp\Devart\691f7f39ac7f43da86.tmp'

The root cause of this issue is the restricted temporary file usage.

Possible reason	How to fix
There was not enough space on the disk C:\ to create temporary files.	Create the C:\Users%WinUser%\AppData\Local\Temp\Devart folder manually.
Saving the temporary file might have failed due to timeout caused by antivirus.	Disable antivirus.
Restricted access to the Devart folder for the user who launches SSMS.	Make sure all the users have both Read and Write permissions.
