B.19.2 Examples

Here are some examples of regquery:

stilts regquery query="title like '%IRAS%'" ofmt=ascii out=iras.txt

Retrieves all the records in the registry whose title field contain the string "IRAS". The '%' characters function as wildcards for the ADQL like operator. The output is written to a local ASCII table which can be examined later.

stilts regquery query="capability/@standardID = 'ivo://ivoa.net/std/ConeSearch'
                       and curation/@publisher like '%astrogrid%'"
                omode=count

Searches for all resources which offer a cone search service and are published by AstroGrid. In this case the records are not stored, but the omode=count output mode counts the rows. This therefore tells you how many AstroGrid cone search services are in the registry.

stilts regquery query="capability/@standardID = 'ivo://ivoa.net/std/SSA'"
                ocmd="keepcols 'identifier accessUrl'"
                ofmt=ascii out=-

Queries the registry for all Simple Spectral Access services. The keepcols filter takes the result and throws away all the columns except for identifier and accessUrl, and these are written to the terminal int ASCII format.
