Here's what i'm trying to do
$sql = "INSERT INTO LocationGeofencePoint( PointNo, Latitude, Longitude)
VALUES ( (SELECT LocationGeofenceID FROM LocationGeofence WHERE GeofenceName='".$name."'),
(SELECT MAX(PointNo)+1 FROM LocationGeofencePoint),
'".$lat."',
'".$long."')";
But this happens.
Every time I add "" the 2nd select stops working.
These are 2 separate tables LocationGeofencePoint and LocationGeofence and I'm trying to get values from LocationGeofence into LocationGeofencePoint.
The result should be something like
LocationGeofencePoint(2 , 14, 54.333, 55.435) (these would be the values)
LocationGeofence(2, Test , group1) (trying to get this '2' into location geofencepoint)
I also tried it just in case it was my editor bugging out but it isn't and i've run out of ideas , any idea on what I can do ? I tried separating the queries but I also need 2 selects to run the 2nd one and that isn't working.
$sql = "INSERT INTO LocationGeofencePoint( PointNo, Latitude, Longitude)
VALUES ( (SELECT LocationGeofenceID FROM LocationGeofence WHERE GeofenceName='".$name."'),
(SELECT MAX(PointNo)+1 FROM LocationGeofencePoint),
'".$lat."',
'".$long."')";
Put same number of column in insert fields and as well as its column values.
First, GeoReferencePoint should be declared as an identity column. You should not be incrementing the value on insert. The database does that for you.
Then, you should be using insert . . . select:
$sql = "INSERT INTO LocationGeofencePoint (PointNo, Latitude, Longitude)
SELECT LocationGeofenceID, $lat, $long
FROM LocationGeofence
WHERE GeofenceName = '".$name."';
And third, this is not right either. The three values being passed in should be using parameters.
Do you mean 'stop working' as the color is not the same color with the first SELECT?
If so, don't worry it just the editor's problem. You will achieve the desired result once you run the code. I experience the same before.

Hi I am trying to add records from one table to another, once i have added a 'user' record, the table that is being selected contains rows of available security options, and the table that is being inserted to is the child table for the user, detailing security options.
I cam across this code in an earlier post, which i am sure works nicely, however i am trying to modify it so that the values from statement, includes two parts, one from the select query and one which is the key from the master record.#
This is the original code I found from this site:
INSERT INTO def (catid, title, page, publish)
SELECT catid, title, 'page','yes' from `abc`
And this is what I am trying to do with it:
$sql = "INSERT INTO Link_UserSecurity (UserFk, ModuleFk) values ('".$keys["UserPk"]."', SELECT ModulePk from Global_Modules)";
CustomQuery($sql);
And this is the error I am getting:
INSERT INTO Link_UserSecurity (UserFk, ModuleFk) values ('4', SELECT
ModulePk from Global_Modules)
See screenshot for further detail
Obviously I am not concating the from statement properly, but would appreciate any help?
You can insert the $keys["UserPk"] variable as if it were a constant in the SQL:
$sql = "INSERT INTO Link_UserSecurity (UserFk, ModuleFk) SELECT '{$keys["UserPk"]}', ModulePk from Global_Modules";
Do note that $keys["UserPk"] must be escaped before adding it into the query. In PDO, it would look like this:
$keys["UserPk"] = $pdo->quote($keys["UserPk"]);
$sql = "INSERT INTO Link_UserSecurity (UserFk, ModuleFk) SELECT '{$keys["UserPk"]}', ModulePk from Global_Modules";
Could be a problem related to the double quotes sequence
"INSERT INTO Link_UserSecurity (UserFk, ModuleFk)
values ('". $keys['UserPk']. "', SELECT ModulePk from Global_Modules)";
but you could use also a select insert
"INSERT INTO Link_UserSecurity (UserFk, ModuleFk)
SELECT '" . $keys['UserPk']. "' , ModulePk from Global_Modules)";
Adding only new and unique records from one table to another. Limiting is a good idea to prevent it from timeout. It can be run several times until all the records copied.
First, select the latest record ID from the table to be copied:
SET #lastcopied =
(SELECT
IF(MAX(a.exp_inotech_id)>0, MAX(a.exp_inotech_id), 0) AS lastcopied
FROM
kll_export_to a
WHERE exp_tezgah = 'A2015-0056');
Then, select and add the records to the destination table:
INSERT INTO kll_export_to
(SELECT * FROM
kll_export_from f
GROUP BY f.exp_inotech_id
HAVING COUNT(f.exp_inotech_id) = 1 AND exp_tezgah = 'A2015-0056' AND f.exp_inotech_id > #lastcopied
ORDER BY exp_inotech_id
LIMIT 1000);
I was trying with this code but it didn't work. it's always get the MAX(eq_no) as 0
$sql1 =mysqli_query($con, "SELECT MAX(eq_no) AS val FROM tech_add_equip");
$sql2 = "INSERT INTO time (eq_no,status_no) VALUES ('$val', 4 );";
if (!mysqli_query($con,$sql2)) {
die('Error: ' . mysqli_error($con)); };
Finally, after I try with this code, it inserts in the right number of MAX(eq_no) but i still cant insert the values of status_no
INSERT INTO time (eq_no) SELECT MAX(eq_no) AS vale FROM tech_add_equip
Could you suggest me what did i missing in the code?
Thank you for your helping
One row returned from SELECT a,b,c statement in sub query is equivalent to set of values that is otherwise hardcoded as ('a-value','b-value','c-value')*. You can hardcode a value within select as well:
INSERT INTO time (eq_no, status_no)
SELECT MAX(eq_no), 4
FROM tech_add_equip
No need for aliases within select - order of columns matters.
*) One row result can be used for IN() clause. Another row would become set of values after comma - can't be uset for IN(), but it works ok for INSERT
('row1-a-value', 'row1-b-value'), ('row2-a-value', 'row2-b-value')
$max = SELECT MAX( customer_id ) FROM customers;
INSERT INTO customers( customer_id, statusno )
VALUES ($max , 4)
How would this be done? I would like to search the database row by row. I might even print out the entire list of the database row by row. But I would also like to show record 1400 for example and determine the info on that row - such as name, gender and country.
Is it possible to use the rownum function to get this done? Or would I need to use a where in the query? But even so how would I determine the row number? Thanks.
Make one column as ID, make it PK and auto_increment. Then your query shell be something like this for #1400 row:
$pdo
->prepare(
"SELECT `name`, `gender`, `country`
FROM `foo_table` WHERE `id` = :id"
)
->execute([':id' => 1400]);
You can use user defined variables to get your rownumber in MySQL
set #nr = 0;
Now you can use this variable (same connection!) in your query
SELECT
#nr := (#nr + 1) rownumber,
*
FROM
table
see: http://dev.mysql.com/doc/refman/5.5/en/user-variables.html
do your select and add
LIMIT n,1
this will skip to n-th element(1400) and show just one result
Is it possible to merge these two mysql queries into one? I want to get NOW() returned to a php variable.
mysql_query('INSERT INTO translate (IDRef, RefType, Lang, Text, LastChangeTS) VALUES ('.$id.', \''.$reftype.'\', \''.$lang.'\', \''.$text.'\', NOW()) ON DUPLICATE KEY UPDATE text = \''.$text.'\', LastChangeTS = NOW()');
mysql_query('SELECT LastChangeTS FROM translate WHERE IDRef = '.$id.' AND RefType = \''.$reftype.'\' AND Lang = \''.$lang.'\'');
You can't merge a insert statement and a select statement. But, you can sure use a stored procedure which inserts the data and then returns the LastChange value.
I have a simple sql query adding a new row to a database and need it to return the a field back to Javascript. The field does Auto_increment but stupildy I called it 'itemId' so mysql_insert_id doesnt work and I don't think I have time to go and amend all the php files that use 'itemId'
Here's my code if it helps:
$addMainItem = "INSERT INTO newsItems (itemId, title, date, tags, location, latitude, longitude, visibleFrontpage, introText, fullDome, liveEvent, customServing, visitorAttraction, retail, digitalCinema, visiblePublic, thumbPath, links, smallDesc) VALUES ('','$title','$date','$tags','$loco','$lat','$long','$visiFront','$intro','$dome ','$live','$custom','$attrac','$retail','$cinema','$public','$thumbPath','$links','$smallDesc')";
$result = mysql_query($addMainItem) or die('error '.mysql_error());
if($result) echo (mysql_insert_id());
I've never heard that naming a column itemId breaking mysql_isert_id().
But you can just select the last inserted record if auto_increment is working.
SELECT * FROM newsItems ORDER BY itemId DESC LIMIT 1
You can put the select statement into a transaction with the insert statement if you're using innoDB and you're worried about a race condition.
mysql_query("SELECT LAST_INSERT_ID()");
Isn't it what are you looking for?
