sql 聚合语句,count的用法
如要获取 result = '1' 的数量
COUNT( CASE WHEN result = '1' THEN result END )
SELECT * FROM ( SELECT batchNo, serviceId, result, projectId, sum(passCount) AS passCount, COUNT( CASE WHEN result = '1' THEN result END ) AS quality, COUNT( CASE WHEN (result = '2' OR result = '0') THEN result END ) AS type, COUNT( CASE WHEN result = '2' THEN result END ) AS qualityTime, COUNT( CASE WHEN result = '0' THEN result END ) AS qualityName, COUNT(questionId) AS questionId, sum(auditCount) AS auditCount, auditTime, id, serviceName FROM picture_audit_helper WHERE 1 = 1 GROUP BY serviceName, DATE_FORMAT(auditTime, '%Y-%m-%d') ) AS t GROUP BY auditTime DESC LIMIT 1
