Figure 3.1. YQL Query Builder


This simple query builder is intended to explore and test simple statements. It does not currently support more advanced statements that include sub-queries, multiple Open Data Tables, or projection.

Features of YQL query builder include:

  • Tabs for each table within a statement: Each Open Data Table used within a given statement is shown as as a separate tab.
  • Limit and tail functions: Easily add functions to get the first or last number of results.
  • Table metadata: Click "show table info" to see metadata within each Open Data Table.
