字符串拆分合并函数
splitByChar(separator, s)
将字符串以‘separator’拆分成多个子串。‘separator’必须为仅包含一个字符的字符串常量。 返回拆分后的子串的数组。 如果分隔符出现在字符串的开头或结尾，或者如果有多个连续的分隔符，则将在对应位置填充空的子串。
splitByString(separator, s)
与上面相同，但它使用多个字符的字符串作为分隔符。 该字符串必须为非空。
arrayStringConcat(arr[, separator])
使用separator将数组中列出的字符串拼接起来。‘separator’是一个可选参数：一个常量字符串，默认情况下设置为空字符串。 返回拼接后的字符串。
alphaTokens(s)
从范围a-z和A-Z中选择连续字节的子字符串。返回子字符串数组。
示例：
SELECT alphaTokens('abca1abc')
┌─alphaTokens('abca1abc')─┐
│ ['abca','abc'] │
└─────────────────────────┘
