此脚本已正常工作2年。我在活动表中删除了超过2000行，也许它太大了？

SQL-问题

$hsql = "SELECT h.ID, h.ukeID, h.normal, h.natt, h.FP, h.HP, h.datumID, h.status, h.orderID, 
h.tilleggID, h.yearID, u.ID as userID, u.level as ulevel, 
u.navn as fnavn, u.etternavn, t.navn as tnavn, o.ID as oID, o.navn as onavn,
 o.pH as opH, o.pB as opB, o.pR as opR, o.pS as opS, o.pP as opP, o.pLE as opLE 
FROM timesheet h LEFT JOIN user u ON u.ID = h.userID LEFT JOIN orders o ON
 o.ordernr = h.orderID LEFT JOIN tillegg t ON t.tilleggnr = h.tilleggID AND 
t.orderID = o.ID".$hsql.$sstr.$yearID."  ORDER BY userID ASC, yearID DESC, ukeID DESC, datumID DESC";

第295行

foreach($hstmt as $hrow) {

Answer 1

切换

SET OPTION SQL_BIG_SELECTS=1

到

SET SESSION SQL_BIG_SELECTS=1

现在有效！

MAX_JOIN_SIZE行; SET SQL_BIG_SELECTS = 1 - 脚本在2年后停止工作
