db* CODECOP Command Line


Trivadis db* CODECOP is a command line utility to check Oracle SQL*Plus files for compliance violations of the Trivadis PL/SQL & SQL Coding Guidelines Version 4.3.

Furthermore McCabe’s cyclomatic complexity, Halstead’s volume, the maintainability index and some other software metrics are calculated for each PL/SQL unit and aggregated on file level.

The code checking results are stored in XML, HTML and Excel files for further processing.

To get the most out of this command line utility you should make it part of your Continuous Integration environment by using the db* CODECOP for SonarQube plugin. This way you may control the quality of your code base over time.

Have also a look at db* CODECOP for SQL Developer if you are interested to check the code quality of PL/SQL code within SQL Developer. It’s a free extension.

db* CODECOP supports custom validators. We provide some example validators in this GitHub repository. You may use these validators as is or amend/extend them to suit your needs.


Here are some screen shot taken from an of an HTML report based on the samples provided with db* CODECOP.

Processing & Content Issue Overview Complex PL/SQL Units File Overview File Issues

These reports reports have been created by db* CODECOP and are based on a simple set of good and bad example files distributed with db* CODECOP:

Report Description
HTML Self-contained HTML report
Excel Excel workbook with the same information as in the HTML report. Contains these sheets: Summary, IssuesPivot, PLSQLUnits, Files and Issues.
JSON JSON file in SonarQube's Generic Issue Import Format. This allows to publish issues in environments where the db* CODECOP plugin is not available such as SonarCloud.

Custom Guidelines as db* CODECOP Plugins

db* CODECOP supports custom validators.

To simplify the development of a validator some examples are provided as Maven project in a dedicated GitHub repository. One validator implements the checks to cover the Naming Conventions for PL/SQL. The following screenshot shows how checks are implemented.

PL/SQL Editor for Eclipse

The following screenshot shows the test case for the checkConstantName method. The outline of the editor reveals the class name to be used for the check.

PL/SQL Editor

The editor is mainly provided to understand the PL/SQL model better. The full model is available as PLSQL.ecore file, which may be explored best within the Eclipse IDE.


You find all releases and release information here.


  1. Uncompress the distributed db* CODECOP archive file into a folder of your choice.

    The archive file contains the following files in the root directory: ReadMe.html, tvdcc.jar,, tvdcc.cmd, PLSQL-and-SQL-Coding-Guidelines.html and the subdirectories lib, eclipse, plugin and sample. SQL scripts with good and bad examples for every guideline are provided in the sample directory.

  2. Amend the settings for JAVA_HOME in tvdcc.cmd to meet your environment settings.

    This is necessary on Windows only, and only if the java.exe cannot be found in the path. Use at least a Java 8 runtime environment (JRE) or development kit (JDK) for JAVA_HOME.

  3. Include TVDCC_HOME in your PATH environment variable for handy interactive usage.

  4. Optionally copy your commercial license file into the TVDCC_HOME directory. For simplicity name the file tvdcc.lic.


If db* CODECOP is invoked without arguments, the following help screen is shown, after the copyright information:

usage: tvdcc path=<path> [options]

mandatory arguments: 
  path=<path>            path to directory containing files to be checked, e.g ./mysourceDir

  -help, -h, -?          print this message
  filter=<filter>        regular expression to filter files, e.g. "myfile.sql" or "(pks|pkb|pkg)$" or "^((?!guideline_7210_65).)*$"
  timeout=<seconds>      maximum seconds allowed to load and parse a file, e.g. 10
  complexity=<value>     list PL/SQL units with cyclomatic complexity greater than this value, e.g. 10
  output=<name>          file name incl. path of output file, e.g ./myreport.html or ./myreport.xlsx
  template=<name>        file name incl. path of XSL stylesheet to create HTML output, e.g ./myhtml.xsl

  json={true|false}      create SonarQube generic issue import JSON file, default is true
  transonly={true|false} transform temporary XML file only, default is false
  cleanup={true|false}   remove temporary XML file, default is true
  check=<list>           comma separated list of guidelines, severities, characteristics to be checked,
                         e.g. "blocker, critical, major, efficiency, 1040", default all guidelines
                         guidelines: 1010, 1020, 1030, 1040, ..., 8410, 8510
                         severities: blocker, critical, major, minor, info
                         characteristics: changeability, efficiency, maintainability, portability,
                                          reliability, reusability, security, testability
                         invalid values are ignored
  skip=<list>            comma separated list of guidelines, serverities, characteristics not to be checked,
                         e.g. "7460, info, portability, testability", invalid values are ignored
                         skips disabled guidelines when empty
  nosonar=false          ignore "-- NOSONAR" marker comments (do not suppress warnings)
  license=<name>         name incl. path to license file, default tvdcc.lic in the root folder
  propertyfile=<name>    load properties from file, e.g. ./
  validator=<name>       decendent of PLSQLValidator and implements PLSQLCopValidator interface, 
                         default is com.trivadis.tvdcc.validators.TrivadisGuidelines3
  genmodel={true|false}  generate SonarQube XML model files, default is false.

Please note that db* CODECOP applies by default a filter to support the following file extensions: .sql, .prc, .fnc, .pks, .pkb, .trg, .vw, .tps, .tpb, .tbp, .plb, .pls, .rcv, .spc, .typ, .aqt, .aqp, .ctx, .dbl, .tab, .dim, .snp, .con, .collt, .seq, .syn, .grt, .sp, .spb, .sps, .pck, .md, .mdown. To process other or additional file extensions, you must pass your own filter expression.

For Markdown files only the code within SQL code blocks is analyzed. If other file extensions than .md and .mdown are used then the content must start with a # to be identified as a Markdown file.

Guideline checks can be disabled when implementing a validator. When the skip option is not defined then all disabled guideines are skipped. To enable all checks pass skip=none.

The value of all options will be included in the output files and on the console output.
