| 12 | * Runtime binding for `dynamodb:ExecuteTransaction`. |
| 13 | * |
| 14 | * Bind this operation to one or more tables inside a function runtime to get a |
| 15 | * callable that runs a PartiQL transaction. Statements reference the bound |
| 16 | * tables by their physical names (resolve them via `table.tableName`); the |
| 17 | * host is granted the transactional read/write actions on every bound table. |
| 18 | * Provide the `ExecuteTransactionHttp` layer on the Function to satisfy the |
| 19 | * binding. |
| 20 | * ### PartiQL |
| 21 | * **Example:** Run a PartiQL Transaction |
| 22 | * ```typescript |
| 23 | * const executeTransaction = yield* AWS.DynamoDB.ExecuteTransaction(table); |
| 24 | * const tableName = yield* table.tableName; |
| 25 | * |
| 26 | * yield* executeTransaction({ |
| 27 | * TransactStatements: [ |
| 28 | * { |
| 29 | * Statement: `UPDATE "${tableName}" SET balance = balance - 10 WHERE pk = ? AND sk = ?`, |
| 30 | * Parameters: [{ S: "account#1" }, { S: "balance" }], |
| 31 | * }, |
| 32 | * { |
| 33 | * Statement: `UPDATE "${tableName}" SET balance = balance + 10 WHERE pk = ? AND sk = ?`, |
| 34 | * Parameters: [{ S: "account#2" }, { S: "balance" }], |
| 35 | * }, |
| 36 | * ], |
| 37 | * }); |
