MySQL查询插入新行

Question

i have this three tables Retailer, imovo, rbpos_epos. What i do is i match them, and get a result which i print in in a page.

What i need to do is insert those results into a new table, i will make a "Match" button which will query the two tables retailer and imovo, and the matches will go to the new table named :matching.

What i need in order to avoid duplications.. is to remove from the retailer table and imovo the matched rows..

Here is the query i use to match:

 $data = mysql_query( "select r.`time`, r.`epos_id`, r.`date`,re.`location`,i.`user_id`,i.`mobile_number`,
       i.`time`, i.`rbpos_id`, i.`date`
from retailer r
join rbpos_epos re on r.epos_id = re.epos_id
join imovo i on i.rbpos_id = re.rbpos_id
             and addtime(r.`time`, '0:0:50') > i.`time`
             and r.`time` < i.`time`
             and r.`date` = i.`date`;
") 
 or die(mysql_error()); 
 Print "<table border cellpadding=3>"; 
  Print "<tr>"; 
 Print "<th>Date:</th>
<th>Time</th>
<th>Location</th>
<th>User ID</th> 
<th>Mobile Number</th>"; 
  Print "</tr>";
 while($info = mysql_fetch_array( $data )) 
 { 

   Print "<tr>"; 
 Print " <td>".$info['date'] . "</td>
<td>".$info['time'] . " </td>
<td>".$info['location'] . " </td>
<td>".$info['user_id'] . " </td>
<td>".$info['mobile_number'] . " </td>
</tr>"; 
 } 

The printed rows are those i need to insert in the matching table.. Thanks!

I tried this:

      $data = mysql_query( "INSERT INTO Matching(date, time, location, user_id, phone)
SELECT 
   r.`date`,
   `time`,
   re.`location`,
   i.`user_id`,
   i.`mobile_number`
from retailer r
join rbpos_epos re on r.epos_id = re.epos_id
join imovo i on i.rbpos_id = re.rbpos_id
and addtime(r.`time`, '0:0:50') > i.`time`
and r.`time` < i.`time`
and 

r. date = i. date ; ") But i get the error:

Column count doesn't match value count at row 1

Answer 1

Use INSERT INTO ... SELECT ... :

INSERT INTO Matching(date, time, location, user_id, phone)
SELECT 
   r.`date`,
   `time`,
   re.`location`,
   i.`user_id`,
   i.`mobile_number`
from retailer r
join rbpos_epos re on r.epos_id = re.epos_id
join imovo i on i.rbpos_id = re.rbpos_id
and addtime(r.`time`, '0:0:50') > i.`time`
and r.`time` < i.`time`
and r.`date` = i.`date`;

Then you have to do this INSERT when the button match is clicked.

Update: If you want to delete the matched rows. You can DELETE with JOIN . Something like:

DELETE r, re, i
from retailer r
join rbpos_epos re on r.epos_id = re.epos_id
join imovo i on i.rbpos_id = re.rbpos_id
and DATE(r.`date`) = DATE(i.`date`);

This will delete all the matched rows from all of the three tables, as explained in the manual:

For the multiple-table syntax, DELETE deletes from each tbl_name the rows that satisfy the conditions.

SQL Fiddle Demo

Note that: it is better to use single column DATETIME instead of two separate parts date and time like what I did in the demo. Then you can use the MySQL Date and time functions to control them, like what I did in the join condition DATE(r.date) = DATE(i.date) .
