• 更新
UPDATE
命令用于修改指定表中现有文档的 行式存储 属性值。请注意,无法更新全文字段或列式属性的内容。如果有这样的需求,请使用 REPLACE 命令。
属性更新支持 RT、PQ 和普通表。只要属性存储在 行式存储 中,所有类型的属性都可以更新。
需要注意的是,文档 ID 不能被更新。
还需要了解的是,更新属性会禁用其 二级索引。如果保持二级索引的连续性至关重要,请考虑完全或部分替换 文档。

和部分 REPLACE
的区别可以参考 这里。
SQL:
UPDATE products SET enabled=0 WHERE id=10;
Query OK, 1 row affected (0.00 sec)
JSON:
POST /update
{
"index":"products",
"id":10,
"doc":
{
"enabled":0
}
}
{
"_index":"products",
"updated":1
}
PHP:
$index->updateDocument([
'enabled'=>0
],10);
Array(
[_index] => products
[_id] => 10
[result] => updated
)
Python:
indexApi = api = manticoresearch.IndexApi(client)
indexApi.update({"index" : "products", "id" : 1, "doc" : {"price":10}})
{'id': 1, 'index': 'products', 'result': 'updated', 'updated': None}
Javascript:
res = await indexApi.update({"index" : "products", "id" : 1, "doc" : {"price":10}});
{"_index":"products","_id":1,"result":"updated"}
java:
UpdateDocumentRequest updateRequest = new UpdateDocumentRequest();
doc = new HashMap<String,Object >(){{
put("price",10);
}};
updateRequest.index("products").id(1L).setDoc(doc);
indexApi.update(updateRequest);
class UpdateResponse {
index: products
updated: null
id: 1
result: updated
}
C#:
Dictionary<string, Object> doc = new Dictionary<string, Object>();
doc.Add("price", 10);
UpdateDocumentRequest updateRequest = new UpdateDocumentRequest(index: "products", id: 1, doc: doc);
indexApi.Update(updateRequest);
class UpdateResponse {
index: products
updated: null
id: 1
result: updated
}
TypeScript:
res = await indexApi.update({ index: "test", id: 1, doc: { cat: 10 } });
{
"_index":"test",
"_id":1,
"result":"updated"
}
Go:
updateDoc = map[string]interface{} {"cat":10}
updateRequest = openapiclient.NewUpdateDocumentRequest("test", updateDoc)
updateRequest.SetId(1)
res, _, _ = apiClient.IndexAPI.Update(context.Background()).UpdateDocumentRequest(*updateRequest).Execute()
{
"_index":"test",
"_id":1,
"result":"updated"
}
可以在单个语句中更新多个属性。例如:
SQL:
UPDATE products
SET price=100000000000,
coeff=3465.23,
tags1=(3,6,4),
tags2=()
WHERE MATCH('phone') AND enabled=1;
Query OK, 148 rows affected (0.0 sec)
JSON:
POST /update
{
"index":"products",
"doc":
{
"price":100000000000,
"coeff":3465.23,
"tags1":[3,6,4],
"tags2":[]
},
"query":
{
"match": { "*": "phone" },
"equals": { "enabled": 1 }
}
}
{
"_index":"products",
"updated":148
}
PHP:
$query= new BoolQuery();
$query->must(new Match('phone','*'));
$query->must(new Equals('enabled',1));
$index->updateDocuments([
'price' => 100000000000,
'coeff' => 3465.23,
'tags1' => [3,6,4],
'tags2' => []
],
$query
);
Array(
[_index] => products
[updated] => 148
)
Python:
indexApi = api = manticoresearch.IndexApi(client)
indexApi.update({"index" : "products", "id" : 1, "doc" : {
"price": 100000000000,
"coeff": 3465.23,
"tags1": [3,6,4],
"tags2": []}})
{'id': 1, 'index': 'products', 'result': 'updated', 'updated': None}
Javascript:
res = await indexApi.update({"index" : "products", "id" : 1, "doc" : {
"price": 100000000000,
"coeff": 3465.23,
"tags1": [3,6,4],
"tags2": []}});
{"_index":"products","_id":1,"result":"updated"}
java:
UpdateDocumentRequest updateRequest = new UpdateDocumentRequest();
doc = new HashMap<String,Object >(){{
put("price",10);
put("coeff",3465.23);
put("tags1",new int[]{3,6,4});
put("tags2",new int[]{});
}};
updateRequest.index("products").id(1L).setDoc(doc);
indexApi.update(updateRequest);
class UpdateResponse {
index: products
updated: null
id: 1
result: updated
}
C#:
Dictionary<string, Object> doc = new Dictionary<string, Object>();
doc.Add("price", 10);
doc.Add("coeff", 3465.23);
doc.Add("tags1", new List<int> {3,6,4});
doc.Add("tags2", new List<int> {});
UpdateDocumentRequest updateRequest = new UpdateDocumentRequest(index: "products", id: 1, doc: doc);
indexApi.Update(updateRequest);
class UpdateResponse {
index: products
updated: null
id: 1
result: updated
}
TypeScript:
res = await indexApi.update({ index: "test", id: 1, doc: { name: "Doc 21", cat: "10" } });
{
"_index":"test",
"_id":1,
"result":"updated"
}
Go:
updateDoc = map[string]interface{} {"name":"Doc 21", "cat":10}
updateRequest = manticoreclient.NewUpdateDocumentRequest("test", updateDoc)
updateRequest.SetId(1)
res, _, _ = apiClient.IndexAPI.Update(context.Background()).UpdateDocumentRequest(*updateRequest).Execute()
{
"_index":"test",
"_id":1,
"result":"updated"
}
当为 32 位属性分配超出范围的值时,它们会被自动裁剪为其低 32 位,且不会有任何提示。例如,如果尝试将 32 位无符号整数更新为值 4294967297,实际上会存储值 1,因为 4294967297(十六进制表示为 0x100000001)的低 32 位为 1(十六进制表示为 0x00000001)。
UPDATE
还可以用于对数值数据类型或数值数据类型数组执行部分 JSON 更新。请确保不要用浮点值更新整数值,因为浮点值将被四舍五入。
SQL:
insert into products (id, title, meta) values (1,'title','{"tags":[1,2,3]}');
update products set meta.tags[0]=100 where id=1;
Query OK, 1 row affected (0.00 sec)

在使用复制时,表名前应加上 cluster_name:
(在 SQL 中),这样更新将被传播到集群中的所有节点。对于通过 HTTP 进行的查询,您应设置一个 cluster
属性。有关更多信息,请参阅设置复制。
{
"cluster":"nodes4",
"index":"test",
"id":1,
"doc":
{
"gid" : 100,
"price" : 1000
}
}
SQL:
update weekly:posts set enabled=0 where id=1;
JSON:
POST /update
{
"cluster":"weekly",
"index":"products",
"id":1,
"doc":
{
"enabled":0
}
}
PHP:
$index->setName('products')->setCluster('weekly');
$index->updateDocument(['enabled'=>0],1);
Python:
indexApi.update({"cluster":"weekly", "index" : "products", "id" : 1, "doc" : {"enabled" : 0}})
Javascript:
res = wait indexApi.update({"cluster":"weekly", "index" : "products", "id" : 1, "doc" : {"enabled" : 0}});
java:
updatedoc = new UpdateDocumentRequest();
doc = new HashMap<String,Object >(){{

doc.Add("enabled", 0);
UpdateDocumentRequest updatedoc = new UpdateDocumentRequest(index: "products", cluster: "weekly", id: 1, doc: doc);
indexApi.Update(updatedoc);
TypeScript:
res = wait indexApi.update( {cluster: 'test_cluster', index : 'test', id : 1, doc : {name : 'Doc 11'}} );
Go:
updateDoc = map[string]interface{} {"name":"Doc 11"}
updateRequest = manticoreclient.NewUpdateDocumentRequest("test", updateDoc)
updateRequest.SetCluster("test_cluster")
updateRequest.SetId(1)
res, _, _ = apiClient.IndexAPI.Update(context.Background()).UpdateDocumentRequest(*updateRequest).Execute()
通过 SQL 进行更新
以下是 SQL UPDATE
语句的语法:
UPDATE table SET col1 = newval1 [, ...] WHERE where_condition [OPTION opt_name = opt_value [, ...]] [FORCE|IGNORE INDEX(id)]
where_condition
的语法与 SELECT 语句中的相同。
多值属性的值集必须作为括号中的逗号分隔列表来指定。要从多值属性中删除所有值,只需将 ()
赋给该属性即可。
SQL:
UPDATE products SET tags1=(3,6,4) WHERE id=1;
UPDATE products SET tags1=() WHERE id=1;
Query OK, 1 row affected (0.00 sec)
Query OK, 1 row affected (0.00 sec)
JSON:
POST /update
{
"index":"products",
"_id":1,
"doc":
{
"tags1": []
}
}
{
"_index":"products",
"updated":1
}
PHP:
$index->updateDocument(['tags1'=>[]],1);
Array(
[_index] => products
[updated] => 1
)
Python:
indexApi.update({"index" : "products", "id" : 1, "doc" : {"tags1": []}})
{'id': 1, 'index': 'products', 'result': 'updated', 'updated': None}
Javascript:
indexApi.update({"index" : "products", "id" : 1, "doc" : {"tags1": []}})
{"_index":"products","_id":1,"result":"updated"}
java:
updatedoc = new UpdateDocumentRequest();
doc = new HashMap<String,Object >(){{
put("tags1",new int[]{});
}};
updatedoc.index("products").id(1L).setDoc(doc);
indexApi.update(updatedoc);
class UpdateResponse {
index: products
updated: null
id: 1
result: updated
}
C#:
Dictionary<string, Object> doc = new Dictionary<string, Object>();
doc.Add("tags1", new List<int> {});
UpdateDocumentRequest updatedoc = new UpdateDocumentRequest(index: "products", id: 1, doc: doc);
indexApi.Update(updatedoc);
class UpdateResponse {
index: products
updated: null
id: 1
result: updated
}
TypeScript:
res = await indexApi.update({ index: 'test', id: 1, doc: { cat: 10 } });
{
"_index":"test",
"_id":1,
"result":"updated"
}
Go:
updateDoc = map[string]interface{} {"cat":10}
updateRequest = manticoreclient.NewUpdateDocumentRequest("test", updateDoc)
updateRequest.SetId(1)
res, _, _ = apiClient.IndexAPI.Update(context.Background()).UpdateDocumentRequest(*updateRequest).Execute()
{
"_index":"test",
"_id":1,
"result":"updated"
}
OPTION
子句是 Manticore 特有的扩展,它允许你控制许多与每次更新相关的选项。其语法为:
OPTION <optionname>=<value> [ , ... ]
这些选项与 SELECT 语句中的相同。特别是对于 UPDATE
语句,可以使用以下选项:
ignore_nonexistent_columns
- 如果设置为 1,表示更新时将静默忽略关于尝试更新不存在于当前表模式中的列的任何警告。默认值为 0。strict
- 该选项用于部分 JSON 属性更新。默认情况下(strict=1),如果UPDATE
查询尝试更新非数字属性,将导致错误。设置 strict=0 时,如果多个属性更新且某些不允许更新,UPDATE
不会导致错误,并且只会对允许的属性进行更改(其余部分将被忽略)。如果SET
中的所有更改均不允许,即使设置 strict=0,该命令也会导致错误。
查询优化器提示
在少数情况下,Manticore 内置的查询分析器可能无法正确理解查询并确定是否应使用按 ID 查询的表。这可能导致像 UPDATE ... WHERE id = 123
这样的查询性能较差。 有关如何强制优化器使用 docid
索引的信息,请参见 [查询优化器提示](../../Searching/Options.md#Query optimizer hints)。
通过 HTTP JSON 进行更新
使用 HTTP JSON 协议进行更新是通过 /update
端点完成的。其语法与 /insert 端点 类似,但这次 doc
属性是必需的。
服务器将以 JSON 对象响应,表明操作是否成功。
JSON:
POST /update
{
"index":"test",
"id":1,
"doc":
{
"gid" : 100,
"price" : 1000
}
}
{
"_index": "test",
"_id": 1,
"result": "updated"
}
需要更新的文档 ID 可以直接使用 id
属性进行设置,如前面的示例所示,或者你也可以通过查询更新文档,并将更新应用于所有匹配该查询的文档:
JSON:
POST /update
{
"index":"test",
"doc":
{
"price" : 1000
},
"query":
{
"match": { "*": "apple" }
}
}
{
"_index":"products",
"updated":1
}
查询语法与 /search 端点 中相同。注意,你不能同时指定 id
和 query
。
刷新属性
FLUSH ATTRIBUTES
FLUSH ATTRIBUTES
命令确保所有活跃表中的内存属性更新被刷新到磁盘。它返回一个标识结果磁盘状态的标签,表示自服务器启动以来实际执行的磁盘属性保存次数。
mysql> UPDATE testindex SET channel_id=1107025 WHERE id=1;
Query OK, 1 row affected (0.04 sec)
mysql> FLUSH ATTRIBUTES;
+------+
| tag |
+------+
| 1 |
+------+
1 row in set (0.19 sec)
另请参阅 attr_flush_period 设置。
批量更新
你可以使用 /bulk
端点在一次调用中执行多个更新操作。该端点仅适用于 Content-Type
设置为 application/x-ndjson
的数据。数据应以换行符分隔的 JSON (NDJSON) 格式编写。也就是说,每行应该包含一个完整的 JSON 语句并以换行符 (可能还包括 )结尾。
JSON:
POST /bulk
{ "update" : { "index" : "products", "id" : 1, "doc": { "price" : 10 } } }
{ "update" : { "index" : "products", "id" : 2, "doc": { "price" : 20 } } }
{
"items":
[
{
"update":
{
"_index":"products",
"_id":1,
"result":"updated"
}
},
{
"update":
{
"_index":"products",
"_id":2,
"result":"updated"
}
}
],
"errors":false
}
/bulk
端点支持插入、替换和删除操作。每条语句都以一个操作类型开头(在这种情况下是 update
)。以下是支持的操作列表:
insert
:插入文档。其语法与 /insert 端点 相同。create
:insert
的同义词。replace
:替换文档。其语法与 /replace 相同。index
:replace
的同义词。update
:更新文档。其语法与 /update 相同。delete
:删除文档。其语法与 /delete 端点 相同。
同时支持按查询更新和按查询删除。

与更新相关的设置
attr_update_reserve
attr_update_reserve=size
attr_update_reserve
是一个针对每个表的设置,用于确定为 blob 属性更新保留的空间。此设置是可选的,默认值为 128k。
当 blob 属性(例如 MVA、多值属性,字符串,JSON)更新时,其长度可能发生变化。如果更新后的字符串(或 MVA、JSON)比旧的短,则会覆盖 .spb
文件中的旧内容。然而,如果更新后的字符串更长,更新内容将写入 .spb
文件的末尾。这个文件是内存映射的,这意味着根据操作系统对内存映射文件的实现,重新调整其大小可能是一个相对较慢的过程。
为了避免频繁调整大小,可以使用此选项指定在 .spb
文件末尾保留的额外空间。

当更新属性时,首先将更改写入属性的内存副本中。此设置允许设置将更新刷新到磁盘的间隔时间。默认值为 0,表示禁用定期刷新,但在正常关闭时仍会执行刷新操作。
