Tabella 34.33. sequences Columns
Name | Data Type | Description |
---|---|---|
sequence_catalog | sql_identifier | Name of the database that contains the sequence (always the current database) |
sequence_schema | sql_identifier | Name of the schema that contains the sequence |
sequence_name | sql_identifier | Name of the sequence |
data_type | character_data | The data type of the sequence. In PostgreSQL™, this is currently always bigint. |
numeric_precision | cardinal_number | This column contains the (declared or implicit) precision of the sequence data type (see above). The precision indicates the number of significant digits. It can be expressed in decimal (base 10) or binary (base 2) terms, as specified in the column numeric_precision_radix. |
numeric_precision_radix | cardinal_number | This column indicates in which base the values in the columns numeric_precision and numeric_scale are expressed. The value is either 2 or 10. |
numeric_scale | cardinal_number | This column contains the (declared or implicit) scale of the sequence data type (see above). The scale indicates the number of significant digits to the right of the decimal point. It can be expressed in decimal (base 10) or binary (base 2) terms, as specified in the column numeric_precision_radix. |
