## Synopsis
|
|
|
|
```shell{:copy}
|
|
codeql query run (--database=<database> | --dataset=<dataset>) [--output=<file.bqrs>] [--threads=<num>] [--ram=<MB>] <options>... -- <file.ql>
|
|
```
|
|
|
|
## Description
|
|
|
|
Run a single query.
|
|
|
|
This command runs single query against a CodeQL database or raw QL
|
|
dataset.
|
|
|
|
By default the result of the query will be displayed on the terminal in
|
|
a human-friendly rendering. If you want to do further processing of the
|
|
results, we strongly recommend using the `--output` option to write the
|
|
results to a file in an intermediate binary format, which can then be
|
|
unpacked into various more machine-friendly representations by
|
|
[codeql bqrs decode](/code-security/codeql-cli/codeql-cli-manual/bqrs-decode).
|
|
|
|
If your query produces results in a form that can be interpreted as
|
|
source-code alerts, you may find [codeql database analyze](/code-security/codeql-cli/codeql-cli-manual/database-analyze) a more convenient way to run it. In particular, [codeql database analyze](/code-security/codeql-cli/codeql-cli-manual/database-analyze) can produce output in the SARIF format, which can be used with an variety of alert viewers.
|
|
|
|
To run multiple queries in parallel, see [codeql database run-queries](/code-security/codeql-cli/codeql-cli-manual/database-run-queries).
|
|
|
|
## Primary options
|
|
|
|
#### `<file.ql>`
|
|
|
|
\[Mandatory] QL source of the query to execute.
|
|
|
|
#### `-o, --output=<file.bqrs>`
|
|
|
|
A file where to output from the query will be written in BQRS format.
|
|
|
|
### Options to select what to query
|
|
|
|
Exactly one of these options must be given.
|
|
|
|
#### `-d, --database=<database>`
|
|
|
|
Path to a CodeQL database to query.
|
|
|
|
#### `--dataset=<dataset>`
|
|
|
|
\[Advanced] Path to a raw QL dataset to query.
|
|
|
|
### Options to control the query evaluator
|
|
|
|
#### `--[no-]tuple-counting`
|
|
|
|
\[Advanced] Display tuple counts for each evaluation step in the query
|
|
evaluator logs. If the `--evaluator-log` option is provided, tuple
|
|
counts will be included in both the text-based and structured JSON logs
|
|
produced by the command. (This can be useful for performance
|
|
optimization of complex QL code).
|
|
|
|
#### `--timeout=<seconds>`
|
|
|
|
\[Advanced] Set the timeout length for query evaluation, in seconds.
|
|
|
|
The timeout feature is intended to catch cases where a complex query
|
|
would take "forever" to evaluate. It is not an effective way to limit
|
|
the total amount of time the query evaluation can take. The evaluation
|
|
will be allowed to continue as long as each separately timed part of the
|
|
computation completes within the timeout. Currently these separately
|
|
timed parts are "RA layers" of the optimized query, but that might
|
|
change in the future.
|
|
|
|
If no timeout is specified, or is given as 0, no timeout will be set
|
|
(except for [codeql test run](/code-security/codeql-cli/codeql-cli-manual/test-run), where the default timeout is 5 minutes).
|
|
|
|
#### `-j, --threads=<num>`
|
|
|
|
Use this many threads to evaluate queries.
|
|
|
|
Defaults to 1. You can pass 0 to use one thread per core on the machine,
|
|
or -*N* to leave *N* cores unused (except still use at least one
|
|
thread).
|
|
|
|
#### `--[no-]save-cache`
|
|
|
|
\[Advanced] Aggressively write intermediate results to the disk cache.
|
|
This takes more time and uses (much) more disk space, but may speed up
|
|
the subsequent execution of similar queries.
|
|
|
|
#### `--[no-]expect-discarded-cache`
|
|
|
|
\[Advanced] Make decisions about which predicates to evaluate, and what
|
|
to write to the disk cache, based on the assumption that the cache will
|
|
be discarded after the queries have been executed.
|
|
|
|
#### `--[no-]keep-full-cache`
|
|
|
|
\[Advanced] Don't clean up the disk cache after evaluation completes.
|
|
This may save time if you're going to do [codeql dataset cleanup](/code-security/codeql-cli/codeql-cli-manual/dataset-cleanup) or [codeql database cleanup](/code-security/codeql-cli/codeql-cli-manual/database-cleanup) afterwards anyway.
|
|
|
|
#### `--max-disk-cache=<MB>`
|
|
|
|
Set the maximum amount of space that the disk cache for intermediate
|
|
query results can use.
|
|
|
|
If this size is not configured explicitly, the evaluator will try to use
|
|
a "reasonable" amount of cache space, based on the size of the dataset
|
|
and the complexity of the queries. Explicitly setting a higher limit
|
|
than this default usage will enable additional caching which can speed
|
|
up later queries.
|
|
|
|
#### `--min-disk-free=<MB>`
|
|
|
|
\[Advanced] Set target amount of free space on file system.
|
|
|
|
If `--max-disk-cache` is not given, the evaluator will try hard to
|
|
curtail disk cache usage if the free space on the file system drops
|
|
below this value.
|
|
|
|
#### `--min-disk-free-pct=<pct>`
|
|
|
|
\[Advanced] Set target fraction of free space on file system.
|
|
|
|
If `--max-disk-cache` is not given, the evaluator will try hard to
|
|
curtail disk cache usage if the free space on the file system drops
|
|
below this percentage.
|
|
|
|
#### `--external=<pred>=<file.csv>`
|
|
|
|
A CSV file that contains rows for external predicate *\<pred>*.
|
|
Multiple `--external` options can be supplied.
|
|
|
|
#### `--xterm-progress=<mode>`
|
|
|
|
\[Advanced] Controls whether to show progress tracking during QL
|
|
evaluation using xterm control sequences. Possible values are:
|
|
|
|
`no`: Never produce fancy progress; assume a dumb terminal.
|
|
|
|
`auto` *(default)*: Autodetect whether the command is running in an
|
|
appropriate terminal.
|
|
|
|
`yes`: Assume the terminal can understand xterm control sequences. The
|
|
feature still depends on being able to autodetect the *size* of the
|
|
terminal, and will also be disabled if `-q` is given.
|
|
|
|
`25x80` (or similar): Like `yes`, and also explicitly give the size of
|
|
the terminal.
|
|
|
|
`25x80:/dev/pts/17` (or similar): show fancy progress on a *different*
|
|
terminal than stderr. Mostly useful for internal testing.
|
|
|
|
### Options for controlling outputting of structured evaluator logs
|
|
|
|
#### `--evaluator-log=<file>`
|
|
|
|
\[Advanced] Output structured logs about evaluator performance to the
|
|
given file. The format of this log file is subject to change with no
|
|
notice, but will be a stream of JSON objects separated by either two
|
|
newline characters (by default) or one if the `--evaluator-log-minify`
|
|
option is passed. Please use `codeql generate log-summary <file>` to
|
|
produce a more stable summary of this file, and avoid parsing the file
|
|
directly. The file will be overwritten if it already exists.
|
|
|
|
#### `--evaluator-log-minify`
|
|
|
|
\[Advanced] If the `--evaluator-log` option is passed, also passing
|
|
this option will minimize the size of the JSON log produced, at the
|
|
expense of making it much less human readable.
|
|
|
|
### Options to control RAM usage
|
|
|
|
#### `-M, --ram=<MB>`
|
|
|
|
Set total amount of RAM the query evaluator should be allowed to use.
|
|
|
|
### Options to control QL compilation
|
|
|
|
#### `--warnings=<mode>`
|
|
|
|
How to handle warnings from the QL compiler. One of:
|
|
|
|
`hide`: Suppress warnings.
|
|
|
|
`show` *(default)*: Print warnings but continue with compilation.
|
|
|
|
`error`: Treat warnings as errors.
|
|
|
|
#### `--[no-]debug-info`
|
|
|
|
Emit source location info in RA for debugging.
|
|
|
|
#### `--[no-]fast-compilation`
|
|
|
|
\[Deprecated] \[Advanced] Omit particularly slow optimization steps.
|
|
|
|
#### `--no-release-compatibility`
|
|
|
|
\[Advanced] Use the newest compiler features, at the cost of
|
|
portability.
|
|
|
|
From time to time, new QL language features and evaluator optimizations
|
|
will be supported by the QL evauator a few releases before they are
|
|
enabled by default in the QL compiler. This helps ensure that the
|
|
performance you experience when developing queries in the newest CodeQL
|
|
release can be matched by slightly older releases that may still be in
|
|
use for Code Scanning or CI integrations.
|
|
|
|
If you do not care about your queries being compatible with other
|
|
(earlier or later) CodeQL releases, you can sometimes achieve a small
|
|
amount of extra performance by using this flag to enable recent
|
|
improvements in the compiler early.
|
|
|
|
In releases where there are no recent improvements to enable, this
|
|
option silently does nothing. Thus it is safe to set it once and for all
|
|
in you global CodeQL config file.
|
|
|
|
The newest features are always on by default in [codeql test run](/code-security/codeql-cli/codeql-cli-manual/test-run).
|
|
|
|
#### `--[no-]local-checking`
|
|
|
|
Only perform initial checks on the part of the QL source that is used.
|
|
|
|
#### `--no-metadata-verification`
|
|
|
|
Don't check embedded query metadata in QLDoc comments for validity.
|
|
|
|
#### `--compilation-cache-size=<MB>`
|
|
|
|
\[Advanced] Override the default maximum size for a compilation cache
|
|
directory.
|
|
|
|
### Options to set up compilation environment
|
|
|
|
#### `--search-path=<dir>[:<dir>...]`
|
|
|
|
A list of directories under which QL packs may be found. Each directory
|
|
can either be a QL pack (or bundle of packs containing a
|
|
`.codeqlmanifest.json` file at the root) or the immediate parent of one
|
|
or more such directories.
|
|
|
|
If the path contains more than one directory, their order defines
|
|
precedence between them: when a pack name that must be resolved is
|
|
matched in more than one of the directory trees, the one given first
|
|
wins.
|
|
|
|
Pointing this at a checkout of the open-source CodeQL repository ought
|
|
to work when querying one of the languages that live there.
|
|
|
|
If you have checked out the CodeQL repository as a sibling of the
|
|
unpacked CodeQL toolchain, you don't need to give this option; such
|
|
sibling directories will always be searched for QL packs that cannot be
|
|
found otherwise. (If this default does not work, it is strongly
|
|
recommended to set up `--search-path` once and for all in a per-user
|
|
configuration file).
|
|
|
|
(Note: On Windows the path separator is `;`).
|
|
|
|
#### `--additional-packs=<dir>[:<dir>...]`
|
|
|
|
If this list of directories is given, they will be searched for packs
|
|
before the ones in `--search-path`. The order between these doesn't
|
|
matter; it is an error if a pack name is found in two different places
|
|
through this list.
|
|
|
|
This is useful if you're temporarily developing a new version of a pack
|
|
that also appears in the default path. On the other hand, it is *not
|
|
recommended* to override this option in a config file; some internal
|
|
actions will add this option on the fly, overriding any configured
|
|
value.
|
|
|
|
(Note: On Windows the path separator is `;`).
|
|
|
|
#### `--library-path=<dir>[:<dir>...]`
|
|
|
|
\[Advanced] An optional list of directories that will be added to the
|
|
raw import search path for QL libraries. This should only be used if
|
|
you're using QL libraries that have not been packaged as QL packs.
|
|
|
|
(Note: On Windows the path separator is `;`).
|
|
|
|
#### `--dbscheme=<file>`
|
|
|
|
\[Advanced] Explicitly define which dbscheme queries should be compiled
|
|
against. This should only be given by callers that are extremely sure
|
|
what they're doing.
|
|
|
|
#### `--compilation-cache=<dir>`
|
|
|
|
\[Advanced] Specify an additional directory to use as a compilation
|
|
cache.
|
|
|
|
#### `--no-default-compilation-cache`
|
|
|
|
\[Advanced] Don't use compilation caches in standard locations such as
|
|
in the QL pack containing the query or in the CodeQL toolchain
|
|
directory.
|
|
|
|
### Options for configuring the CodeQL package manager
|
|
|
|
#### `--registries-auth-stdin`
|
|
|
|
Authenticate to GitHub Enterprise Server Container registries by passing
|
|
a comma-separated list of \<registry\_url>=\<token> pairs.
|
|
|
|
For example, you can pass
|
|
"<https://containers.GHEHOSTNAME1/v2/=TOKEN1,https://containers.GHEHOSTNAME2/v2/=TOKEN2>"
|
|
to authenticate to two GitHub Enterprise Server instances.
|
|
|
|
This overrides the CODEQL\_REGISTRIES\_AUTH and GITHUB\_TOKEN environment
|
|
variables. If you only need to authenticate to the github.com Container
|
|
registry, you can instead authenticate using the simpler
|
|
`--github-auth-stdin` option.
|
|
|
|
#### `--github-auth-stdin`
|
|
|
|
Authenticate to the github.com Container registry by passing a
|
|
github.com GitHub Apps token or personal access token via standard
|
|
input.
|
|
|
|
To authenticate to GitHub Enterprise Server Container registries, pass
|
|
`--registries-auth-stdin` or use the CODEQL\_REGISTRIES\_AUTH environment
|
|
variable.
|
|
|
|
This overrides the GITHUB\_TOKEN environment variable.
|
|
|
|
### Common options
|
|
|
|
#### `-h, --help`
|
|
|
|
Show this help text.
|
|
|
|
#### `-J=<opt>`
|
|
|
|
\[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.
|
|
|
|
#### `--verbosity=<level>`
|
|
|
|
\[Advanced] Explicitly set the verbosity level to one of errors,
|
|
warnings, progress, progress+, progress++, progress+++. Overrides `-v`
|
|
and `-q`.
|
|
|
|
#### `--logdir=<dir>`
|
|
|
|
\[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.)
|
