Preview your schema in SQL mode

By default, SQL mode queries show the schema browser pane on the left side of the query. Just like the visual mode schema browser, you can see and search through all the schemas, tables, and columns available from your selected data source.

Select a column from the schema browser to add the column name to your SQL query.

The schema, table, and column names shown in the schema browser are the SQL names, not the display names provided in the data source’s schema settings.

Column data types

Each column in the schema browser has an icon corresponding to the column’s data type.


A comma-separated list of values contained within square brackets ([ ])

Icon for the array data type


Either a true or false value, where true is 1 and false is 0

Because boolean columns shows true values to 1 and false values to 0 in the result table, boolean columns become number data types after the query.
