Meta-parameter
Independent of the TQL query that is going to run, it may be important to use Teneo Query Language to present the data in a certain way or to run a limited form of the query, e.g. to test it before putting it into operation. This is where meta-parameters come in. Meta-parameters are optional instructions that you can add to your query. They generally affect the behavior of TQL, rather than operating directly on the data.
In our query the meta-parameter is limit 30, telling TQL to only show 30 results:
la s.id, t.e.userInput, t.e2.answerText: t.e.userInput != "" limit 30
The three meta-parameters available in TQL are:
| Meta-parameter name | Description |
|---|---|
order by |
Sort results by a certain property or variable, either ascending or descending |
limit |
Limit the query to n results (to save processing time if you don't need to see all the results) |
sample |
Show a sample of results (to save processing time; also when first testing a query to confirm that it does get results) |
Meta parameters are added to the end of a valid TQL query with no separator (comma). An exception is the meta-parameter sample, which is placed at the beginning of the query.
