Dear SQLiters,
I think the answer to my question is "NO", but may be I missed something...
Can column name come from a table, i.e. from another select? Example:
SELECT (SELECT columnName FROM columnNameTable WHERE condition how to select
limit 1)
FROM table which has that columnName;
Or this is not doable within SQL and I must execute internal select separately
and have application compose second (external) select?
Thank you,
Roman
I was going to say, try using a SQL prepared statement.
For example, in Postgres you can write something like this:
execute format( 'SELECT %I FROM table that has that columnName',
(SELECT columnName FROM columnNameTable WHERE condition how to select limit
1) );
But I don't know if SQLite can do that in SQL; you might have to use the host
language.
