36.43. `sequences`

The view sequences contains all sequences defined in the current database. Only those sequences are shown that the current user has access to (by way of being the owner or having some privilege).

Table 36.41. sequences Columns

Name Data Type Description

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.
`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`.
`start_value`	`character_data`	The start value of the sequence
`minimum_value`	`character_data`	The minimum value of the sequence
`maximum_value`	`character_data`	The maximum value of the sequence
`increment`	`character_data`	The increment of the sequence
`cycle_option`	`yes_or_no`	`YES` if the sequence cycles, else `NO`

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.

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.

start_value

character_data

The start value of the sequence

minimum_value

character_data

The minimum value of the sequence

maximum_value

character_data

The maximum value of the sequence

increment

character_data

The increment of the sequence

cycle_option

yes_or_no

YES if the sequence cycles, else NO

Note that in accordance with the SQL standard, the start, minimum, maximum, and increment values are returned as character strings.
