The available columns for any given table are fetched from a system table called "sys_tablecolumns". A specific table name is provided in the WHERE criteria to restrict the table from which the column information is fetched:

import cdata.quickbase as mod
conn = mod.connect("[email protected];Password=test_1234;Domain=test.quickbase.com;ApplicationToken='bwkxrb5da2wn57bzfh9xn24';")
cur = conn.cursor()
cmd = "SELECT * FROM sys_tablecolumns WHERE TableName = '[CData].[QuickBase].SampleTable_1'"
cur.execute(cmd)
rs = cur.fetchall()
for row in rs:
	print(row)
