DBA_HIST_SQLBIND

DBA_HIST_SQLBIND displays historical information on bind variables used by SQL cursors.

This view contains snapshots of V$SQL_BIND_CAPTURE.

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
