bqrs diff

Compute the difference between two result sets.


GitHub CodeQL is licensed on a per-user basis upon installation. You can use CodeQL only for certain tasks under the license restrictions. For more information, see "About the CodeQL CLI."

If you have a GitHub Advanced Security license, you can use CodeQL for automated analysis, continuous integration, and continuous delivery. For more information, see "About GitHub Advanced Security."

This content describes the most recent release of the CodeQL CLI. For more information about this release, see

To see details of the options available for this command in an earlier release, run the command with the --help option in your terminal.


codeql bqrs diff <options>... -- <file1> <file2>


Compute the difference between two result sets.


Primary Options


[Mandatory] First BQRS file to compare.


[Mandatory] Second BQRS file to compare.


Write rows only present in file1 to this file.


Write rows only present in file2 to this file.


Write rows present in both file1 and file2 to this file.


Comma-separated list of result set names to copy directly to the corresponding output instead of comparing. If --both is given, that output is taken from file1. Defaults to 'nodes,edges,subpaths' to simplify handling of path-problem results.


[Advanced] Include internal entity IDs in the comparison. Entity IDs are not comparable across databases, but for result sets that originate from the same database this can help distinguish entities with the same location and label.

Common options

-h, --help

Show this help text.


[Advanced] Give option to the JVM running the command.

(Beware that options containing spaces will not be handled correctly.)

-v, --verbose

Incrementally increase the number of progress messages printed.

-q, --quiet

Incrementally decrease the number of progress messages printed.


[Advanced] Explicitly set the verbosity level to one of errors, warnings, progress, progress+, progress++, progress+++. Overrides -v and -q.


[Advanced] Write detailed logs to one or more files in the given directory, with generated names that include timestamps and the name of the running subcommand.

(To write a log file with a name you have full control over, instead give --log-to-stderr and redirect stderr as desired.)


[Advanced] Controls the location of cached data on disk that will persist between several runs of the CLI, such as downloaded QL packs and compiled query plans. If not set explicitly, this defaults to a directory named .codeql in the user's home directory; it will be created if it doesn't already exist.

Available since v2.15.2.
