A SQL lookup Service provide a way to implement a The Scout documentation has been moved to https://eclipsescout.github.io/. that is very efficient to configured, if the The Scout documentation has been moved to https://eclipsescout.github.io/. is resolved with a database.
Instead of implementing the 4 methods (getDataByKey(LookupCall call), getDataByText(LookupCall call), getDataByAll(LookupCall call), getDataByRec(LookupCall call)), it is possible to defined the behavior of the lookup service with some configuration properties and events.

SqlSelect: what should be the result
Possibility to use some special tags:
- key
- text
- all
- rec
Depending on the function that is called (by key, by text, by all, by rec) only the portion of the SQL query beetween the corresponding tag is keept.
The getDataByKey(LookupCall call) is attached to the query as binding. Therefore all getters on the call, are available in the query.
SELECT language_id, name, NULL, NULL, NULL, NULL, NULL, 1, NULL, 1 FROM LANGUAGE <key>WHERE language_id = :key</key> <text>WHERE UPPER(name) LIKE UPPER('%'||:text||'%')</text>
