 SELECT s.* from (
SELECT t.ID,t.time_old,
    substring_index( substring_index( t.all_content, ‘；‘, b.help_topic_id + 1 ), ‘；‘, -1 ) content_split
-- t.* 
FROM
    excel_lvli t
    JOIN mysql.help_topic b ON b.help_topic_id < ( LENGTH( t.all_content ) - LENGTH( REPLACE ( t.all_content, ‘；‘, ‘‘ ) ) + 1 )
and t.all_content like ‘%；%‘
and t.all_content like ‘%画了许多%‘ 
) s 
WHERE  LENGTH(s.content_split) >0 ;

SELECT
    substring_index( substring_index( t.context, ‘,‘, b.help_topic_id + 1 ), ‘,‘, - 1 ) 
FROM
    test.test t
    JOIN mysql.help_topic b ON b.help_topic_id < ( LENGTH( t.context ) - LENGTH( REPLACE ( t.context, ‘,‘, ‘‘ ) ) + 1 );
