更新记录 转载请注明出处: 2022年8月1日 发布。 2022年7月2日 从笔记迁移到博客。 内置函数说明(FUNCTION) Sever 提供了众多功能强大、方便易用的函数。使用这些函数,可以极大地提高数据库的管理。SQL Server中的函数从功能方面主要分为以下几类:字符串函数、数学函数、数据转换函数、文本和图像函数、日期和时间函...
The s() function is similar to unquote(), in that it returns a Literal node. However, it accepts a format string similar to C's sprintf(). Currently, the only specifier is %s. s('bar()'); // => bar() s('bar(%s)', 'baz'); // => bar("baz") s('bar(%s)', baz); ...
The following table lists each built-in (native) function and operator and provides a short description of each one. For a table listing functions that are loadable at runtime, see Section 14.2, “Loadable Function Reference”. Table 14.1 Built-In Functions and Operators NameDescriptionDeprecated ...

内置函数(BuiltinFunctions) 更新时间:2024-08-16 函数说明 Fn::Base64Encode:返回输入字符串的Base64编码结果。 Fn::Base64Decode:返回输入字符串的Base64解码结果。 Fn::MergeMap:将列表中多个Map合并成一个Map。 Fn::Join:将一组值连接起来,用特定分隔符隔开。 Fn::Select:数据元容器通过查询索引返回...
Whereas, the disordered pore distribution as well as surface catalysis in these hosts still restrict the performance of Li–S batterie. Herein, a synthesis of built-in ultrafine CoS 2 catalysis in confined ordered micro-mesoporous carbon (OMMC) nanoreactors is proposed to accelerate LiPSs conversion...
String function - 将字符串作为输入并返回一个字符串。 Aggregate function - 将列表作为输入并返回原子。 Uniform function - 获取列表并返回相同计数的列表。 Mathematical function - 获取数字参数并返回数字参数。 Miscellaneous function - 除上述以外的所有功能。
