This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Case
HOW- Goal
- Execute SQL statements within pgx transactions using pgx.Tx.Exec, parse command tag results, prevent execution on closed transactions, recover from errors via savepoints, and handle multi-statement batches
- Packages
- Symbols
-
- pgx.Tx.Exec
- Environment
- go
- Created
- 2026-08-17T23:32:54Z
Contract
- pgx.Tx.Exec returns a structured pgconn.CommandTag with RowsAffected and command predicates rather than sql.Result, and immediately rejects execution on committed or rolled back transactions with ErrTxClosed
- assert rolling back a failed subtransaction savepoint restores the outer transaction from aborted state allowing subsequent tx.Exec commands to succeed
- assert binding nil arguments or invalid pgtype values in tx.Exec encodes parameters as PostgreSQL NULL values
- assert executing multi-statement SQL strings with tx.Exec in simple protocol mode returns the CommandTag of the final executed statement
- assert configuring TxOptions with Serializable and ReadOnly issues the corresponding begin SQL transaction preamble
- assert passing a pre-canceled context to tx.Exec immediately returns context.Canceled without executing on the connection
