+## cl.distributeddatamgr.2 OH_Predicates 结构体的函数指针成员变量返回值类型由OH_Predicates 变更为OH_Predicates *
+
+**变更影响**
+
+该变更为不兼容变更，用户使用OH_Predicates结构体中的函数指针变量时，需要按照新类型进行使用。
+
+**关键接口/组件变更**
+
+修改前的OH_Predicates成员变量原型：
+
+ ```ts
+    OH_Predicates (*equalTo)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+    OH_Predicates (*notEqualTo)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+    OH_Predicates (*beginWrap)(OH_Predicates *predicates);
+    OH_Predicates (*endWrap)(OH_Predicates *predicates);
+    OH_Predicates (*orOperate)(OH_Predicates *predicates);
+    OH_Predicates (*andOperate)(OH_Predicates *predicates);
+    OH_Predicates (*isNull)(OH_Predicates *predicates, const char *field);
+    OH_Predicates (*isNotNull)(OH_Predicates *predicates, const char *field);
+    OH_Predicates (*like)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+    OH_Predicates (*between)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+    OH_Predicates (*notBetween)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+    OH_Predicates (*greaterThan)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+    OH_Predicates (*lessThan)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+    OH_Predicates (*greaterThanOrEqualTo)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+    OH_Predicates (*lessThanOrEqualTo)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+    OH_Predicates (*orderBy)(OH_Predicates *predicates, const char *field, OH_OrderType type);
+    OH_Predicates (*distinct)(OH_Predicates *predicates);
+    OH_Predicates (*limit)(OH_Predicates *predicates, unsigned int value);
+    OH_Predicates (*offset)(OH_Predicates *predicates, unsigned int rowOffset);
+    OH_Predicates (*groupBy)(OH_Predicates *predicates, char const *const *fields, int length);
+    OH_Predicates (*in)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+    OH_Predicates (*notIn)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+    OH_Predicates (*clear)(OH_Predicates *predicates);
+ ```
+
+修改后的OH_Predicates成员变量原型：
+
+ ```ts
+   OH_Predicates *(*equalTo)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+   OH_Predicates *(*notEqualTo)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+   OH_Predicates *(*beginWrap)(OH_Predicates *predicates);
+   OH_Predicates *(*endWrap)(OH_Predicates *predicates);
+   OH_Predicates *(*orOperate)(OH_Predicates *predicates);
+   OH_Predicates *(*andOperate)(OH_Predicates *predicates);
+   OH_Predicates *(*isNull)(OH_Predicates *predicates, const char *field);
+   OH_Predicates *(*isNotNull)(OH_Predicates *predicates, const char *field);
+   OH_Predicates *(*like)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+   OH_Predicates *(*between)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+   OH_Predicates *(*notBetween)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+   OH_Predicates *(*greaterThan)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);

+   OH_Predicates *(*groupBy)(OH_Predicates *predicates, char const *const *fields, int length);
+   OH_Predicates *(*in)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+   OH_Predicates *(*notIn)(OH_Predicates *predicates, const char *field, OH_VObject *valueObject);
+   OH_Predicates *(*clear)(OH_Predicates *predicates);
+ ```
+
+**适配指导**
+示例代码如下：
+
+变更前代码示例：
+
+```
+predicates->beginWrap(predicates).equalTo(predicates, "data1", valueObject).orOperate(predicates);
+```
+
+变更后代码示例：
+
+```
+predicates->beginWrap(predicates)->equalTo(predicates, "data1", valueObject)->orOperate(predicates);
+```
