Write query

As you enter your script in the query editor, the autocomplete feature suggests:

  • Query syntax keywords such as SQL functions or aliases.
  • Values that match table or column names within a schema.

IOMETE tracks table aliases and suggests them as autocomplete options. For example, if you execute a query using call_center as c or call_center c as an alias, the next time you type c, the autocomplete feature suggests the alias as an option.
