sqlite 从固定字符串分隔

WITH split(word, str) AS (
    -- alternatively put your query here
    -- SELECT '', category||',' FROM categories
    SELECT '', 'Auto,A,1234444,dsfdd,sd,sd,77'||','
    UNION ALL SELECT
    substr(str, 0, instr(str, ',')),
    substr(str, instr(str, ',')+1)
    FROM split WHERE str!=''
) SELECT word FROM split WHERE word!='';

sqlite 从表中获取数据

WITH split(word, str) AS (
    SELECT '', (select chi_sht from tr_map_org_basic where com_name_en='code cat' and status=1)||','
    UNION ALL SELECT
    substr(str, 0, instr(str, ',')),
    substr(str, instr(str, ',')+1)
    FROM split WHERE str!=''
) SELECT word FROM split WHERE word!='';

sqlite 从表中获取数据，union all 连接语句

WITH split(word, str) AS (
    SELECT '', (select chi_sht from tr_map_org_basic where com_name_en='code cat' and status=1)||','
    UNION ALL SELECT
    substr(str, 0, instr(str, ',')),
    substr(str, instr(str, ',')+1)
    FROM split WHERE str!=''
) SELECT word FROM split WHERE word!=''
union all select eng_sht from tr_map_org_basic where com_name_en='code cat';
