Crossmatches table on sky position against SQL table
of sending an HTTP query to a remote cone search service for each
match (i.e. each row of the input table), it executes an SQL query
directly. The query is a SELECT statement with a WHERE clause which
makes restrictions on Right Ascension and Declination columns;
the names of these columns must be given as parameters.
The effect is that of a spatial join between a client-side table and
a table stored in the database.
This command can only be used if you have access to an SQL database via JDBC. The details of how to configure a JDBC connection to a database are discussed in Section 3.4 - obviously you will need a database to connect to and appropriate read permissions on it as well as the relevant drivers.
Note: this task was known as
sqlcone in its experimental
form in STILTS v1.3.
