| 248 | * Provide the implementation with |

| 250 | * |
| 251 | * ### Running SQL |
| 252 | * **Example:** Query a Workgroup |
| 253 | * ```typescript |
| 254 | * const sql = yield* RedshiftData.Statements(workgroup, { database: "dev" }); |
| 255 | * const result = yield* sql.query("SELECT 1 AS n"); |
| 256 | * // result.Records -> [[{ longValue: 1 }]] |
| 257 | * ``` |
| 258 | * |
| 259 | * **Example:** Run a Batch of Statements in One Transaction |
| 260 | * ```typescript |
| 261 | * const submitted = yield* sql.executeBatch({ |
| 262 | * Sqls: ["CREATE TABLE IF NOT EXISTS events(id int)", "INSERT INTO events VALUES (1)"], |
| 263 | * }); |
| 264 | * // sub-statement ids are `${submitted.Id}:1`, `${submitted.Id}:2` |
| 265 | * const described = yield* sql.describe(submitted.Id!); |
| 266 | * ``` |
| 267 | * |
| 268 | * **Example:** Cancel a Running Statement |
| 269 | * ```typescript |
| 270 | * const submitted = yield* sql.execute({ Sql: "SELECT count(*) FROM big_table" }); |
| 271 | * const { Status } = yield* sql.cancel(submitted.Id!); |
| 272 | * ``` |
| 273 | * |
| 274 | * ### Browsing Metadata |
| 275 | * **Example:** List Databases, Schemas and Tables |
| 276 | * ```typescript |
| 277 | * const { Databases } = yield* sql.listDatabases(); |
| 278 | * const { Schemas } = yield* sql.listSchemas({ SchemaPattern: "public" }); |
| 279 | * const { Tables } = yield* sql.listTables({ SchemaPattern: "public" }); |
| 280 | * const { ColumnList } = yield* sql.describeTable({ Schema: "public", Table: "events" }); |
| 281 | * ``` |
| 282 | * |
| 283 | * **Example:** Serve Query Results from a Lambda Function |
| 284 | * ```typescript |
| 285 | * export default QueryFunction.make( |
| 286 | * { main: import.meta.url, functionUrl: true }, |
| 287 | * Effect.gen(function* () { |
| 288 | * const namespace = yield* RedshiftServerless.Namespace("Analytics", { |
| 289 | * dbName: "analytics", |
| 290 | * adminUsername: "admin", |
| 291 | * manageAdminPassword: true, |
| 292 | * }); |
| 293 | * const workgroup = yield* RedshiftServerless.Workgroup("Analytics", { |
| 294 | * namespaceName: namespace.namespaceName, |
| 295 | * baseCapacity: 8, |
| 296 | * }); |
| 297 | * // init — bind the Data API to the workgroup |
| 298 | * const sql = yield* RedshiftData.Statements(workgroup, { |
| 299 | * database: "analytics", |
| 300 | * }); |
| 301 | * |
| 302 | * return { |
