Question

我有这个SQL查询，当我在MSSQL Management Studio中执行它时运行正常，但是当我尝试在PHP中执行它时它没有输出。

有什么建议吗？

//获取ID

 $atz_id = $_GET['atz_id'];

// SQL查询

 $q2 = "
 declare @atzID int             set @atzID=$atz_id; 


 if object_id('tempdb..#vesture1') is not null drop table #vesture1
 select distinct
 atz_id,
 datums s_dat,
 cast(NULL as datetime) b_dat,
 tips
 into #vesture1
 from guna..erg2_atzistas_o o
 where
 darbiba=1
 and atz_id=@atzID


  update #vesture1 set b_dat=(select top 1 datums from guna..erg2_atzistas_o where atz_id=#vesture1.atz_id and darbiba=0 and tips=#vesture1.tips and datums > #vesture1.s_dat order by datums asc)


 if object_id('tempdb..#vesture2') is not null drop table #vesture2
 select distinct
 atz_id,
 convert(varchar, s_dat, 104) s_dat,
 convert(varchar, b_dat, 104) b_dat,
 substring((select ', '+tips from #vesture1 where atz_id=v.atz_id and s_dat=v.s_dat and isnull(b_dat,0)=isnull(v.b_dat,0) order by tips for xml path('')), 3, 3000) 'sugas'
into #vesture2
from #vesture1 v

select * from #vesture2 order by s_dat, b_dat
";

//运行查询

$res2=mssql_query($q2);

//检查是否有一些输出（没有 - 其他查询输出0或行数，这不是）

$num_rows2 = mssql_num_rows($res2);


 echo $num_rows2;

//输出数据

echo "<table border='1' class='saraksts_table' width='100%' cellspacing='0'>
<tr class='saraksts_header'>
<th><center><font size='1.2px'>info</font></center></th>
<th><center><font size='1.2px'>xxxx</font></center></th>
<th><center><font size='1.2px'>axxa</font></center></th>
<th><center><font size='1.2px'>SAAAa</font></center></th>
</tr>";

while($row2 = mssql_fetch_array($res2))
{
echo "<tr style=background-color:white;>";
echo "<td>" . $row2['atz_id'] . "</td>";
echo "<td>" . $row2['s_dat'] . "</td>";
echo "<td>" . $row2['b_dat'] . "</td>";
echo "<td>" . $row2['sugas'] . "</td>";
echo "</tr>";
}
echo "</table>";

Answer 1

我经常会将PHP MySQL查询编写为3个步骤。

定义查询

$ query =“SELECT * FROM tablename WHERE value =''”;
执行查询：

$ result = mysql_query（$ query）或die（mysql_error（））;
验证查询结果：

if（mysql_num_rows（$ result）== 0）{}

或者您可以将步骤2和3结合起来，如下所示：

if (!result = mysql_query($query)) {
    // looks like this didnt return any data
} else {
    // woot, we have something to work with     
}

大多数情况下，您看到的错误意味着您的查询无效，从而导致使用虚假数据集，而不是返回任何行。

我使用PHP中的错误报告的3个步骤将为您提供MySQL反馈错误代码以及PHP中的行，这通常可以帮助您隔离查询中出错的位置。

尝试在/etc/freetds/freetds.conf中添加这两行

[global]
tds version = 8.0
client charset = UTF-8

Answer 3

我必须转换数据类型 - ＆gt; http://msdn.microsoft.com/en-us/library/aa226054%28v=sql.80%29.aspx

更新选择 - 花了一段时间才弄明白

           select atz_id, s_dat, b_dat, **cast(sugas as varchar)as sugas** from #vesture2 order by s_dat, b_dat;

感谢所有人的帮助。
