需求SQL 字段中的字符串拆成多行显示.
实现:MYSQL SUBSTRING_INDEX(COL1,'字符串分隔符号',位置)
SQL: select
t2.help_topic_id as ID
,SUBSTRING_INDEX(SUBSTRING_INDEX(RecordIdentifier,' ',t2.help_topic_id+1),' ',-1) as RecordIdentifier
,RecordIdentifier
,Substring_index(RecordIdentifier,' ',help_topic_id+1)
from
(select
extractvalue(t1.xml_content,'/DSExport/Job/Record/@Identifier') as RecordIdentifier
from awm_job t1)
t1 left join mysql.help_topic t2
on t2.help_topic_id < LENGTH(t1.RecordIdentifier)-length(replace(t1.RecordIdentifier,' ',''))+1;
Result:
