Description¶

ASSUME treats all values in the given column in the given table as being of the specified type when the storage_type_definition is:

(column_name) VALUES ARE datatype

This overrides any other information about the type of a value.

ASSUME treats all column names in the given table as being of the given type when the storage_type_definition is:

NAMES ARE <type>

ASSUME treats all column values in the given table as being of the given type unless overridden by a column-specific ASSUME or column-specific metadata in the table's definition.

Assigning multiple data type overrides¶

Assign multiple overrides at once for the same table by separating storage_type_definitions with commas:

ASSUME ks.table NAMES ARE uuid,
  VALUES ARE int, (col)
  VALUES ARE ascii

Examples¶

ASSUME users NAMES ARE text, VALUES are text;

ASSUME users(user_id) VALUES are uuid;
