Mysql查询:date_format和sprintf()

Question

我想在MySQL查询中使用sprintf()和date_format.

这是查询:

mysql_select_db($database_exdb, $expdb);
$query_eventeditrs = sprintf("SELECT eventid, groupid, title, DATE_FORMAT(dateofevent, '%W, %M %d, %Y'), timeofevent, location, details, presenter, bio FROM events WHERE eventid = %s", GetSQLValueString($colname_eventeditrs, "int")); 

我收到的错误是:

“Warning: sprintf() [fun
ction.sprintf]: Too few arguments. Query was Empty” 

Plz的帮助

你必须使用额外的%'s来转义日期格式字符串,试试这个:

sprintf("SELECT eventid, groupid, title, 
DATE_FORMAT(dateofevent, '%%W, %%M %%d, %%Y'), 
ti meofevent, location, details, presenter, bio 
FROM events 
WHERE eventid = %s", GetSQLValueString($colname_eventeditrs, "int"));
