Get tables in a database

Here we get name, description and number of rows of tables from IRSA database

from astrobook import sql2df

query = """
SELECT table_name, description, irsa_nrows
FROM TAP_SCHEMA.tables
WHERE irsa_nrows IS NOT NULL
ORDER BY irsa_nrows DESC
"""

df = sql2df(query, api='irsa')

Get columns of a table

Let's get columns of the table basic from SIMBAD

from astrobook import sql2df

query = """
SELECT column_name, description
FROM TAP_SCHEMA.columns
WHERE table_name='basic'
"""

df = sql2df(query, api='simbad')
