@sinoform/helper-condition-api

构建 API 查询条件的辅助模块。

支持两种风格构建 API 查询条件，即：

• 流式方法
• sql 模板

根据个人喜好，两种风格二选一即可。

简单示例

查询姓名包含 张 的查询条件。

流式方法：

import { build$ } from '@sinoform/helper-condition-api';

const currentUser = getCurrentUser();
const context = { formDesignId: '表单id', currentUser };
const $ = build$(context);

// 创建查询条件
const condition = $('userName').contain('张');
// 或者
condition = $('userName').like('%张%');

sql 模板风格：

import { sql } from '@sinoform/helper-condition-api';
const condition = sql`userName like '%张%'`;

组合多个查询条件

可以使用 and、or、not 逻辑运算符组合多个查询条件。

示例 1

import { build$ } from '@sinoform/helper-condition-api';

const currentUser = getCurrentUser();
const context = { formDesignId: '表单id', currentUser };
const $ = build$(context);

const useNameCondition = $('userName').contain('张');
const ageCondition = $('age').gt(18);
const condition = $.and(userNameCondition, ageCondition);

import { sql } from '@sinoform/helper-condition-api';

const condition = sql`
  USER_NAME like '%张%'
  AND age > 18
`;

示例 2

import { $ } from '@sinoform/helper-condition-api';

const condition = $.or(
  $('userName').contain('张'),
  $('userName').contain('李'),
);

import { sql } from '@sinoform/helper-condition-api';

const condition = sql`
  USER_NAME like '%张%'
  OR USER_NAME like '%李%'
`;

示例 3

import { $ } from '@sinoform/helper-condition-api';

const condition = $.and(
  $.or($('userName').contain('张'), $('userName').contain('李')),
  $('age').gt(18),
);

import { sql } from '@sinoform/helper-condition-api';

const condition = sql`
  (
    USER_NAME like '%张%'
    OR USER_NAME like '%李%'
  ) AND (
    age > 18
  )
`;

$('field_1').like('张%');

sql`field_1 like '张%'`;

notLike

$('field_1').notLike('张%');

sql`
  field_1 not like '张%'
`;

range

between ... and ...

$('field_1').range(1, 3);

sql`
  field_1 between 1 and 3
`;

and

逻辑与的关系

$.and($('field_1').gt(10), $('field_1').lt(100), $('user_name').equal('张三'));

sql`
  field_1 > 10 and field_1 < 100 and user_name = '张三'
`;

or

逻辑或的关系

$.or($('field_1').gt(10), $('field_1').lt(100), $('user_name').equal('张三'));

sql`
  field_1 > 10 or field_1 < 100 or user_name = '张三'
`;

not

逻辑非的关系

$.not($('field_1').equal(10));
// 或者

$('field_1').not.equal(10);

sql`
  !(field_1 = 10)
`;

likeLeft

文本左包含关系

$('field_1').likeLeft('张');

sql`field_1 like '张%'`;

querySelfAll

查询仅自己可见的数据

import { build$ } from '@sinoform/helper-condition-api';

const currentUser = getCurrentUser();
const context = { formDesignId: '表单id', currentUser };
const $ = build$(context);

const condition = $.querySelfAll();

相当于：

import { $ } from '@sinoform/helper-condition-api';

const condition = $.and(
  $('PERM.FORMDESIGN_ID').equal(formDesignId),
  $('PERM.SUBJECT_ID').equal(currentUserId),
);

queryDeptAll

查询出自己和部门可见的数据

import { build$ } from '@sinoform/helper-condition-api';

const currentUser = getCurrentUser();
const context = { formDesignId: '表单id', currentUser };
const $ = build$(context);

const condition = $.queryDeptAll();

相当于：

import { $ } from '@sinoform/helper-condition-api';

$.or(
  $.and(
    $('PERM.FORMDESIGN_ID').equal(formDesignId),
    $('PERM.SUBJECT_ID').equal(currentUserId),
  ),
  $.and(
    $('PERM.FORMDESIGN_ID').equal(formDesignId),
    $('PERM.SUBJECT_ID').equal(deptId),
    $('PERM.SUBJECT_TYPE').equal('superDept'),
  ),
);
