方法详细资料

executeStatement

protected Result executeStatement()

从类复制的说明: PreparableStatement

Executes the statement directly (non-prepared). Implementation is dependent on the statement type.

指定者:

executeStatement 在类中 PreparableStatement<Result>

返回:

the object returned from the lower level statement execution

getPrepareStatementXMessage

protected XMessage getPrepareStatementXMessage()

从类复制的说明: PreparableStatement

Returns the XMessage needed to prepare this statement. Implementation is dependent on the statement type.

指定者:

getPrepareStatementXMessage 在类中 PreparableStatement<Result>

返回:

the XMessage that prepares this statement

executePreparedStatement

protected Result executePreparedStatement()

从类复制的说明: PreparableStatement

Executes a previously server-prepared statement. Implementation is dependent on the statement type.

指定者:

executePreparedStatement 在类中 PreparableStatement<Result>

返回:

the object returned from the lower level statement execution

executeAsync

public CompletableFuture<Result> executeAsync()

从接口复制的说明: Statement

Execute the statement asynchronously.

指定者:

executeAsync 在接口中 Statement<ModifyStatement,Result>

返回:

CompletableFuture for result

set

public ModifyStatement set(String docPath,
                           Object value)

从接口复制的说明: ModifyStatement

Add an update to the statement setting the field as the document path to the given value for all documents matching the search criteria.

指定者:

set 在接口中 ModifyStatement

参数:

docPath - document path to the given value

value - value to set

返回:

ModifyStatement

ModifyStatement

patch

public ModifyStatement patch(DbDoc document)

从接口复制的说明: ModifyStatement

Takes in a patch object and applies it on all documents matching the modify() filter, using the JSON_MERGE_PATCH() function. Please note that DbDoc does not support expressions as a field values, please use ModifyStatement.patch(String) method if you need such functionality.

指定者:

参数:

document - patch object

返回:

ModifyStatement

patch

public ModifyStatement patch(String document)

从接口复制的说明: ModifyStatement

Takes in a document patch and applies it on all documents matching the modify() filter, using the JSON_MERGE_PATCH() function. A document patch is similar to a JSON object, with the key difference that document field values can be nested expressions in addition to literal values.
Example:
collection.modify("_id = :id")
.patch("{\"zip\": address.zip-300000, \"street\": CONCAT($.name, '''s street: ', $.address.street)}")
.bind("id", "2").execute();

指定者:

patch 在接口中 ModifyStatement

参数:

document - patch object

返回:

ModifyStatement

arrayInsert

public ModifyStatement arrayInsert(String field,
                                   Object value)

从接口复制的说明: ModifyStatement

Insert a value into the specified array.

指定者:

arrayInsert 在接口中 ModifyStatement

参数:

field - document path to the array field

value - value to insert

返回:

ModifyStatement

arrayAppend

public ModifyStatement arrayAppend(String docPath,
                                   Object value)

从接口复制的说明: ModifyStatement

Append a value to the specified array.

指定者:

arrayAppend 在接口中 ModifyStatement

参数:

docPath - document path to the array field

value - value to append

返回:

ModifyStatement

where

@Deprecated
public ModifyStatement where(String searchCondition)

Deprecated in Connector/J 8.0.17. Please use filter criteria in the operation starting method.

从类复制的说明: FilterableStatement

Add search condition to this statement.

 table.delete().where("age == 13").execute();
 

覆盖:

where 在类中 FilterableStatement<ModifyStatement,Result>

参数:

searchCondition - expression

返回:

this statement
