一:理论 oracle 截取字符(substr),检索字符位置(instr) case when then else end语句使用 收藏 常用函数:substr和instr 1.SUBSTR(string,start_position,[length]) 求子字符串,返回字符串 解释:string 元字符串 start_position 开始位置(从0开始) length 可选项,子字符串的个数 For example: substr("ABCDEFG", ...

ERRCODE_STRING_DATA_RIGHT_TRUNCATION 报错:value too long for type character varying(xxx) 问题原因:字段长度超过了VARCHAR类型的长度限制。 解决方法:处理数据或将VARCHAR的长度设置得更长,或者将字段类型改为TEXT。 ERRCODE_PROGRAM_LIMIT_EXCEEDED或者Exceed Odps Scan Limit ...
CONTAINS(column_name, 'NEAR((AA,BB),5)') The string AA one two three four five BB would be a match. In the following example, the query specifies for three search terms, AA, BB, and CC within a maximum distance of five: SQL Copy CONTAINS(column_name, 'NEAR((AA,BB,CC),5)'...
fn:contains ($arg1 as xs:string?, $arg2 as xs:string?) as xs:boolean? 参数 $arg1 要测试的字符串值。 $arg2 要查找的子字符串。 注解 如果$arg 2的值是零长度字符串,则函数返回True。 如果 $arg 1的值为零长度字符串,并且 $arg 2的值不是零长度字符串,则函数返回False。
