在函数代码中，确保在注入sqlQuery之前声明与绑定（绑定到function.json）属性。以下是一个示例：

function getClients(context, req) { context.log('JavaScript HTTP trigger function processed a request.');

const collection = context.bindings.myClientsCollection; const q = req.query.q || "";

let sqlQuery = ""; if (q !== "") { sqlQuery = SELECT * FROM c WHERE c.name LIKE "%${q}%"; } else { sqlQuery = "SELECT * FROM c"; }

const requestOptions = { partitionKey: "Clients", enableCrossPartitionQuery: true };

context.log("----------------------------------------"); context.log(collection); context.log("----------------------------------------");

context.bindings.outputClients = collection.items.query(sqlQuery, requestOptions);

context.done(); }

在这个例子中，我们确保在使用context.bindings.myClientsCollection之前打印并检查了collection。这确保了我们正常连接到Cosmos DB并绑定到正确的集合。
