Database opens one client span per statement (0.7.0), but Effect's SQL driver still opened its own span inside it, named after the database and carrying the query text. Every statement produced two client spans, and a consumer that wanted one had to switch the tracer off around its database calls, which also hid the statement span.

The statement span is now the only span a statement gets:

• It carries db.query.text (the statement as sent: Postgres keeps $n, ClickHouse inlines values, exactly what the driver's span recorded) and, on failure, db.response.status_code (the SQLSTATE) beside error.type.

• The driver call runs with the tracer disabled. fromSqlClient({ driverSpans: true }) keeps the driver's span as a child, for what only it records (server.address, connection waits).

• observe runs inside the statement span, so attributes a consumer annotates there land on it. A test pins that, since consumers rely on it to add peer.service and similar.

• Plain SQL (Db.sql) spans were named after the database system (postgresql). They are now named after the leading operation and first table the text names (UPDATE items), with db.operation.name and db.collection.name, as the conventions allow for parsed text. The patterns match the ones Maple's warehouse derives query shapes with, so existing shape names carry over.

Minor bump (default trace shape changes). docs/database.md tracing section updated.

Tests

• src/database/tracing.test.ts: no driver span by default, db.query.text is the parameterized SQL, SQLSTATE on a syntax error, observe annotations land on the statement span, driverSpans: true nests the driver span under it, and plain SQL is named from its text (with and without a table).
• vitest run (1027 passed), typecheck, doc citation/export/example checks.

Summary by CodeRabbit

• New Features
  • SQL statement traces now include query text and clearer operation and table details. Errors can include database response status information.
  • By default, a statement is represented by a single trace span. SQL driver spans can be enabled when additional detail is needed.
  • Statement spans can include custom annotations.
• Documentation
  • Updated tracing guidance to explain span naming, attributes, and driver-span options.

Walkthrough

Database statement spans now record query and error attributes and derive operation and collection names from plain SQL. SQL driver spans are disabled by default and can be enabled with driverSpans.

Changes: Database tracing

Layer / File(s)	Summary
Statement span attributes and naming src/database/tracing.ts, src/database/tracing.test.ts, docs/database.md	Statement spans record query text and SQLSTATE response codes. Plain SQL statements derive operation and collection values for span attributes and naming. Tests cover annotations and statements with and without a table.
SQL driver span control src/database/database.ts, src/database/tracing.test.ts, .changeset/statement-span-only.md	FromSqlClientOptions adds driverSpans. Row-returning statements and commands disable driver tracing by default; tests verify that enabling the option nests a driver span inside the statement span.

Some plain-SQL queries produce misleading tracing labels. This is a bounded observability issue that should be fixed or accepted before merge.

Full details: Title check

Explanation

The title names the primary change: the statement span becomes the only span a statement gets by default. The changeset covers this. The docs, database.ts (driverSpans option), tracing.ts (db.query.text, plain SQL naming, error attributes), and tracing tests all reflect it. The title is specific and concise, and it fits the 11-word, 70-character length a teammate would scan. It omits the driverSpans opt-in and the plain-SQL naming rule, which is acceptable because it does not need to cover every detail.

Minor · Functional Correctness · Quick win

Mask SQL string literals before matching the first table.

FIRST_TABLE searches raw SQL. For SELECT 'from Alice' FROM users, it matches the text inside the literal, so db.collection.name and the default span summary become Alice instead of users.

🐛 Suggested fix

-		collection: FIRST_TABLE.exec(statement.sql)?.[1],
+		collection: FIRST_TABLE.exec(statement.sql.replace(/'(?:[^']|'')*'/g, "''"))?.[1],
