我正在尝试创建一个事件，但收到以下错误:
我的查询:
CREATE EVENT insert_count
ON SCHEDULE
EVERY 50 SECOND
COMMENT 'bla bla bla bla bla bla.'
DO BEGIN
INSERT INTO teste (nome, conectado, desconectado)
SELECT parceiro.nomeP AS 'Parceiro',
SUM(di.connectedOr = 'true') AS 'ClientesConectados',
SUM(di.connectedOr = 'false') AS 'ClientesDesconectados'
FROM vpn AS di
JOIN parceiro
ON parceiro.codParceiro = di.idpartner
WHERE di.comName REGEXP 'skytef-'
GROUP BY di.idpartner
END
最佳答案
问题可能出在您的 SUM 上。我认为它们应该看起来像这样: SUM(IF(di.connectedOr = 'true', 1, 0))
