Column Datatype NULL Description

SNAP_ID

NUMBER

NOT NULL

Unique snapshot ID

DBID

NUMBER

NOT NULL

Database ID for the snapshot

INSTANCE_NUMBER

NUMBER

NOT NULL

Instance number for the snapshot

SQL_ID

VARCHAR2(13)

NOT NULL

SQL identifier of the parent cursor in the library cache

NAME

VARCHAR2(128)

Name of the bind variable

POSITION

NUMBER

NOT NULL

Position of the bind variable in the SQL statement

DUP_POSITION

NUMBER

If the binding is performed by name and the bind variable is duplicated, then this column gives the position of the primary bind variable.

DATATYPE

NUMBER

Internal identifier for the bind data type. Beginning in Oracle Database 12c, a number representing a PL/SQL data type can appear in this column.

DATATYPE_STRING

VARCHAR2(15)

Textual representation of the bind data type. Beginning in Oracle Database 12c, a text representation of a PL/SQL-only data type can appear in this column. If the actual data type is a PL/SQL sub type, the name of the data type, not the sub type will be displayed.

CHARACTER_SID

NUMBER

National character set identifier

PRECISION

NUMBER

Precision (for numeric binds)

SCALE

NUMBER

Scale (for numeric binds)

MAX_LENGTH

NUMBER

Maximum bind length

WAS_CAPTURED

VARCHAR2(3)

Indicates whether the bind value was captured (YES) or not (NO)

LAST_CAPTURED

DATE

Date when the bind value was captured. Bind values are captured when SQL statements are executed. To limit the overhead, binds are captured at most every 15 minutes for a given cursor.

VALUE_STRING

VARCHAR2(4000)

Value of the bind represented as a string

VALUE_ANYDATA

ANYDATA

Value of the bind represented using the self-descriptive Sys.AnyData data type. This representation is useful to programmatically decode the value of the bind variable. This column is NULL if a PL/SQL-only data type appears in the DATATYPE column.

CON_DBID

NUMBER

The database ID of the PDB for the sampled session

CON_ID

NUMBER

The ID of the container that CON_DBID identifies. Possible values include:

  • 0: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs.

  • 1: This value is used for rows containing data that pertain to only the root

  • n: Where n is the applicable container ID for the rows containing data
