A Collection of assorted Teradata Tools
tdtools is a collection of POSIX style command-line tools that provide an alternate way to access system information (metadata) from Teradata. Of course, most of the information can also be obtained by querying Teradata's Dictionary tables and views (
- I originally developed these tools for my personal use. I am making them open-source in the hope that someone else might find them useful. These tools do not come with any expressed or implied warranty.
- These tools are not endorsed by Teradata Inc.
- Most of the functionality provided byt the tools rely on information contained in Teradata Data Dictionary tables and view. Therefore,
DBCobjects is required.
The latest version of Python3 series is always recommended. However, at least one prior-to-latest version of Python3 will be supported.
tdtools depends on tdtypes (for Teradata metadata information) and yappt (for formatting output). These packages and their dependencies will be downloaded and installed automatically if you use the standard python installer,
pip, to install tdtools.
pip utility to install
$ pip install -U tdtools
C:\>python -m pip install -U tdtools
Following is a brief description of each tool. Use
--help command-line option to show detailed description of all supported options.
||Print Teradata database hierarchy.|
||Print Teradata Tree hierarchy (reverse View hierarchy)|
||Maintain View hierarchy as static data in a table (needed for
||Generate (and optionally run) TPT load script.|
||Generate (and optionally run) TPT export script.|
||Print current statistics information for Teradata objects (Table or Join-Index).|
||Print Teradata permissions on objects or to users/roles|
All show* utilities generate Teradata object DDLs.
||Database or user|
||Grants to user/role|
||Wrapper around Teradata
All ls* utilities print Teradata object information. Currently supported commands are:
||Views (optionally lists dependent objects hierarchy)|
You can optionally supply
tdconn_site.py module to allow custom run-time option(s) to be added to all of the above tools. This modifies how the tools obtain a Teradata connection. This feature builds on customization offered by tdtypes module (see tdtypes documentation for details).
tdconn_site.py module must supply at least two functions.
dbconn_args(parser)which should accept ArgumentParser object and add any custom command-line options to the
dbconnect(args)which overrides the default function with the same name that is provided by tdtypes package, but must accept an argument which will be the result of
- There was a defect in certain earlier releases of Teradata Database that caused views based on NOPI tables to be not detected correctly. A patch is available from Teradata that fixes this defect.
Report bugs using issue tracker. I'll try to provide a fix as soon as I can. If you already have a fix, send me a pull request.
