kyua db-exec —
Executes a SQL statement in a results file
kyua db-exec |
[--no-headers]
[--results-file file]
statement |
The kyua db-exec command provides a way to
execute an arbitrary SQL statement within the database. This command is
mostly intended to aid in debugging, but can also be used to extract
information from the database when the current interfaces do not provide the
desired functionality.
The input database must exist. It makes no sense to use
kyua db-exec on a nonexistent or empty database.
The kyua db-exec command takes one or more
arguments, all of which are concatenated to form a single SQL statement.
Once the statement is executed, kyua db-exec prints
the resulting table on the screen, if any.
The following subcommand options are recognized:
--no-headers--results-file
path, -s
pathkyua db-exec
to automatically load the latest results file from the current test suite.
The following values are accepted:
See Results files for more details.
Results files contain, as their name implies, the results of the execution of a test suite. Each test suite executed by kyua-test(1) generates a new results file, and such results files can be loaded later on by inspection commands such as kyua-report(1) to analyze their contents.
Results files support identifier-based lookups and also path name lookups. The differences between the two are described below.
The default naming scheme for the results files provides simple support for identifier-based lookups and historical recording of test suite runs. Each results file is given an identifier derived from the test suite that generated it and the time the test suite was run. Kyua can later look up results files by these fields.
The identifier follows this pattern:
<test_suite>.<YYYYMMDD>-<HHMMSS>-<uuuuuu>
where ‘test_suite’ is the path to the root of the test suite that was run with all slashes replaced by underscores and ‘YYYYMMDD-HHMMSS-uuuuuu’ is a timestamp with microsecond resolution.
When using the default naming scheme, results files are stored in the ~/.kyua/store/ subdirectory and each file holds a name of the form:
~/.kyua/store/results.<identifier>.db
Results files are simple SQLite databases with the schema described in the /usr/share/kyua/store/schema_v?.sql files. For details on the schema, please refer to the heavily commented SQL file.
The kyua db-exec command returns 0 on
success or 1 if the SQL statement is invalid or fails to run.
Additional exit codes may be returned as described in kyua(1).
