The connection string used to connect to the database. It is recommended to remove embedded credentials.
Server=(localdb)\v11.0;Integrated Security=true;
db.instance.id
string
An identifier (address, unique name, or any other identifier) of the database instance that is executing queries or mutations on the current connection. This is useful in cases where the database is running in a clustered environment and the instrumentation is able to record the node executing the query. The client may obtain this value in databases like MySQL using queries like select @@hostname.
mysql-e26b99z.example.com
db.name
string
This attribute is used to report the name of the database being accessed. For commands that switch the database, this should be set to the target database (even if the command fails). [1]
customers; main
db.operation
string
The name of the operation being executed, e.g. the MongoDB command name such as findAndModify, or the SQL keyword. [2]
findAndModify; HMSET; SELECT
db.statement
string
The database statement being executed.
SELECT * FROM wuser_table; SET mykey "WuValue"
db.system
string
An identifier for the database management system (DBMS) product being used. See below for a list of well-known identifiers.
other_sql
db.user
string
Username for accessing the database.
readonly_user; reporting_user
[1]: In some SQL databases, the database name to be used is called "schema name". In case there are multiple layers that could be considered for database name (e.g. Oracle instance name and schema name), the database name to be used is the more specific layer (e.g. Oracle schema name).
[2]: When setting this to an SQL keyword, it is not recommended to attempt any client-side parsing of db.statement just to get this property, but it should be set if the operation name is provided by the library being instrumented. If the SQL statement has an ambiguous operation, or performs more than one operation, this value may be omitted.
db.system has the following list of well-known values. If one of them applies, then the respective value MUST be used, otherwise a custom value MAY be used.

It is not recommended to attempt any client-side parsing of db.statement just to get this property, but it should be set if it is provided by the library being instrumented. If the operation is acting upon an anonymous table, or more than one table, this value MUST NOT be set.
db.cassandra.consistency_level MUST be one of the following:

The implementation SHOULD reference the elasticsearch schema in order to map the path part values to their names.
