查询失败：错误：语法错误在或附近＆＃34; WHERE＆＃34;

Question

我有一个由于某种原因失败的数据库查询，我找不到原因！这是查询pg_query ($conn, 'SELECT ref from music ORDER BY artist WHERE ref=$ref')

这是输出：

Warning: pg_query(): Query failed: ERROR: syntax error at or near "WHERE" LINE 2: ORDER BY artist WHERE ref=3 ^ in /berw/homes1/t/tor10/public_html/cs25010/basket.php on line 44

非常感谢任何帮助！

Answer 1

试试这个

您需要在Where Clause

之前使用Order BY Clause

pg_query ($conn, 'SELECT ref from music  WHERE ref=$ref ORDER BY artist')

编辑：

您似乎使用$ref作为字符串，然后将其用单引号

括起来

pg_query ($conn, 'SELECT ref from music  WHERE ref='.$ref.' ORDER BY artist')
