字段 IS NULL

例: isNull("name")

参数:

condition - 执行条件

column - 字段

返回:

children

in

default Children in(R column,
                    java.util.Collection<?> coll)

ignore

in

Children in(boolean condition,
            R column,
            java.util.Collection<?> coll)

字段 IN (value.get(0), value.get(1), ...)

例: in("id", Arrays.asList(1, 2, 3, 4, 5))

注意！集合为空若存在逻辑错误，请在 condition 条件中判断 如果集合为 empty 则不会进行 sql 拼接

condition - 执行条件

column - 字段

coll - 数据集合

返回:

children

in

default Children in(R column,
                    java.lang.Object... values)

ignore

in

Children in(boolean condition,

            java.lang.Object... values)

字段 IN (v0, v1, ...)

例: in("id", 1, 2, 3, 4, 5)

注意！数组为空若存在逻辑错误，请在 condition 条件中判断 如果动态数组为 empty 则不会进行 sql 拼接
