PHP页面中的多个SQL查询

Question

I am trying to display 3 tables on one page. 我试图在一页上显示3个表。

I'm using 3 different queries, but it's giving me an error on the second query. 我正在使用3个不同的查询，但第二个查询却给我一个错误。 I'm assuming this isn't a syntax error, but it could be. 我假设这不是语法错误，但可能是。 Let me know if you need any more details. 让我知道是否需要更多详细信息。

Here's the error: 这是错误：

Parse error: syntax error, unexpected T_VARIABLE 解析错误：语法错误，意外的T_VARIABLE

For This Line: 对于此行：

$result2 = mssql_query("SELECT *

Answer 1

Your JOIN clause in the $result2 query includes " ON tale2.user_id=table4.user_id; " . $ result2查询中的JOIN子句包括“ ON tale2.user_id = table4.user_id;”。 I assume you mean table2.user_id rather than tale2.user_id? 我假设您是说table2.user_id而不是tale2.user_id？ In fact, it's more than an assumption, since you're selecting from table2, not tale2. 实际上，这不仅仅是假设，因为您是从table2中选择的，而不是tale2。 (I would have included this as a comment but don't have the reputation level yet.) （我本来会将此作为评论，但还没有信誉级别。）

Answer 2

Change this: 更改此：

<?php//insert form results into database
$result3 = mssql_query("SELECT *

...to this: ...对此：

<?php
//insert form results into database
$result3 = mssql_query("SELECT *

Edit: There should at least be a space between <?php and code or a comment (after the last p ). 编辑： <?php和代码或注释之间至少应有一个空格（在最后一个p ）。

In not doing so, will cause a parse error. 否则，将导致解析错误。

Invalid: <?php// comment 无效： <?php// comment

Invalid: <?phpecho "Hello"; 无效： <?phpecho "Hello";

As opposed to: 相对于：

Valid: <?php // comment 有效： <?php // comment

Valid: <?php echo "Hello"; 有效： <?php echo "Hello";
