type_id | int8 | 19 |
|
null | The name of the property/slot is a cvterm. The meaning of the property is defined in that cvterm. For example, cvterms may come from the FlyBase miscellaneous cv. |
|||
value | text | 2147483647 |
|
√ | null | The value of the property, represented as text. Numeric values are converted to their text representation. This is less efficient than using native database types, but is easier to query. |
||
rank | int4 | 10 |
|
0 | Property-Value ordering. Any expression_cvterm can have multiple values for any particular property type - these are ordered in a list using rank, counting from zero. For properties that are single-valued rather than multi-valued, the default 0 value should be used. |
