SELECT
crb_issues.id,
crb_issues.title,
crb_issues.volume,
crb_issues.number,
crb_issues.publish_date,
crb_issues.is_publish,
crb_issues.pdfFile,
crb_issues.flyer,

crb_issues.`status`,
crb_issues.issueType,
crbissue_data.typeValue,
crbissue_data.typeFieldname,
crbissue_data.typeData,
crbissue_data.issueId,
crbissue_data.id
FROM
crb_issues
INNER JOIN crbissue_data ON crb_issues.id = crbissue_data.issueId
WHERE
crb_issues.is_publish = '1' AND crb_issues.issueType = '0'

我的表格数据：

现在从上面的代码我只想从当前场景中获取id 151，这是我从数据库中最新插入的id。我也想要151和它的3个记录集。

Answer 1

SELECT
    crb_issues.id,
    crb_issues.title,
    crb_issues.volume,
    crb_issues.number,
    crb_issues.publish_date,
    crb_issues.is_publish,
    crb_issues.pdfFile,
    crb_issues.flyer,
    crb_issues.cover,
    crb_issues.`status`,
    crb_issues.issueType,
    crbissue_data.typeValue,
    crbissue_data.typeFieldname,
    crbissue_data.typeData,
    crbissue_data.issueId,
    crbissue_data.id
FROM crb_issues
INNER JOIN (SELECT MAX(id) id 
            FROM crb_issues
            WHERE crb_issues.is_publish = '1' AND crb_issues.issueType = '0') latest
      ON crb_issues.id = latest.id
INNER JOIN crbissue_data ON crb_issues.id = crbissue_data.issueId

如何使用DESC在顶部获取最新记录，但记录来自两个表
