Anyone know how to insert bar/pipe delimited array in an array field?
With comma its working but when I change it to bar it produces error "malformed array literal"
example (works):
insert into table (arrayfield) values ('{"var1","var2","var3"}')
example (doesn't work):
insert into table (arrayfield) values ('{"var1"|"var2"|"var3"}')
btw i'm using postgres 8.2 and PHP and i can't use comma as delimiter for various reasons.
If you can use values without quotes because you know that no pipe is in your data, then you can use:
insert into table (arrayfield) select string_to_array('var1|var2|var3','|');
If you need that your values are quoted on your pipe-delimited string then it gets complicated. If that's the case then I think you should format and quote properly your array using ARRAY['val1','val2','val3'] syntax in PHP.

It's new for me to use richtext but a user has to be able to insert pictures or to change his text. So I'm using ckeditor but i've some trouble with it.
When a user write into the rich text he can write things using apostrophe and comas.
I'll use an example. Let's imagine i want to write :
It's quite difficult to open a picture, a file blablabla
The problem is that in the inserting query looks like that
Insert into tab (txt1,txt2) values ('value1','value2')
If the user uses comas or apostrophe the richtext cannot be correctly inserted. Moreover, I use longtext in my MySQL database to store the text.
My questions are :
How to store the richtext written by the user
What type should be the column in my MySQL database to correctly store the richtext to be able to give it back
The problem i have is
Erreur SQL !INSERT INTO detail_article(ID,Problem,Num,URL,Solving,Description) VALUES(16,'Chrome : clearing datas',4,'','
\r\nCHROME CACHE CLEARING :
\r\n\r\n
blablabala
\r\n\r\n
In the 'windows explorer', do the fallowing statment....blablabla
\r\n','')
It's a sample of my text but i think the problem is caused by the quotes and the coma
Your problem must come from your PHP script which seems not to escape the pieces of data it send.
If it's not working with the richtext containing commas and apostrophes, then it's probably that the query send to your database isn't escape.
For example, if you have such content :
$value2 = "Catch',em all";
$value1 = "Hello boys";
And if you try to store it in database without escaping it, then the resulting SQL query will looks like :
INSERT INTO tab (value1, value2) VALUES ('Hello boys', 'Catch', em all);
which will be an incorrect SQL statement because of incorrect syntax.
If you use some escape method like PDO::quote(), your input will be inserted in a safe way that won't produce any error (syntax).
Make sure your script does escape the params you send with either PDO::quote() (https://php.net/manual/fr/pdo.quote.php) or either mysqli_real_escape_string (http://php.net/manual/fr/mysqli.real-escape-string.php)
I am trying to insert data into a MySQL table which contains 19 columns however not all the rows are being stored.
Only a few of the rows are being stored and I'm getting the error message:
There is error in your SQL syntax. Check your syntax for your SQL version.
Although when I echo the variables, they are working fine.
My code is as follows:
$sql="CREATE TABLE tb(tb1 VARCHAR(50),tb2 VARCHAR(50),tb3 VARCHAR(100),tb4 VARCHAR(100),tb5 VARCHAR(100),tb6
VARCHAR(100),tb7 VARCHAR(100),tb8 VARCHAR(100),tb9 VARCHAR(100),tb10 VARCHAR(100),tb11 VARCHAR(100),tb12
VARCHAR(100),tb13 VARCHAR(100),tb14 VARCHAR(100),tb15 VARCHAR(100),tb16 VARCHAR(100),tb17 VARCHAR(100),tb18
VARCHAR(100),tb19 VARCHAR(100))";
foreach ($xml->product as $character)
{
$a1=$character->category->primary;
$b2=$character->category->secondary;
$c3=$character->URl->product;
$d4=$character->URL->productImage;
$e5=$character->URL->buy;
$f6=$character->description->short;
$g7=$character->description->long;
$h8=$character->discount->amount;
$i9=$character->discount->time;
$j10=$character->price->sale;
$k11=$character->price->retail;
$l12=$character->brand;
$m13=$character->shipping->cost->amount;
$n14=$character->shipping->cost->currency;
$o15=$character->shipping->information;
$p16=$character->shipping->availability;
$q17=$character->keywords;
$r18=$character->upc;
$s19=$character->m1;
$sql="INSERT INTO tb
(tb1,tb2,tb3,tb4,tb5,tb6,tb7,tb8,tb9,tb10,tb11,tb12,tb13,tb14,tb15,tb16,tb17,tb18,tb19) VALUES
('$a1','$b2','$c3','$d4','$e5','$f6','$g7','$h8','$i9','$j10','$k11','$l12','$m13','$n14','$o15','$p16','$q17','$r18','$s19')";
mysql_query($sql,$conn);
}
If ANY of your values contains an apostrophe, your query breaks.
Use mysql_real_escape_string() around each of your values as a quick fix.
A more correct and future-proof solution is to stop using mysql_* functions and instead start using PDO, making use of features like prepared statements as these take care of escaping things for you.
This is a formatted comment. A frequent mistake with this type of query is that the number of fields does not match the number of values. That is easier to troubleshoot if you type your query like this:
insert into table (
field1
, field2
, etc
)
values (
value1
, value2
, etc
)
This format makes it easier to count the number of fields and values. Sometimes the problem is with a certain field or value. This format, with the commas at the start of the line, make it easier to comment out blocks of code to isolate the problem.
I am having a very strange problem inserting values into my mysql database, using php, so i was running a test, the simplest of the simple insert; the following doesnt work:
<?php
include("config.php"); // put the *FULL* path to the file.
mysql_query("INSERT INTO 'lms'.'test2' ('trn') VALUES ('17')");
?>
However the following works:(Note the difference in single quotes)
<?php
include("config.php"); // put the *FULL* path to the file.
mysql_query("INSERT INTO `lms`.`test2` (`trn`) VALUES ('17')");
?>
I really can't see what the problem is could I get sum assistance please
You don't need to encapsulate tables within a query unless they have space or they are reserved words.
INSERT INTO 'lms'.'test2' ('trn') VALUES ('17')
// This makes no real sense to the db. It should be:
INSERT INTO lms.test2 (trn) VALUES ('17')
If the column trn accepts numbers, it really should be:
INSERT INTO lms.test2 (trn) VALUES (17)
With MySQL, you can use the tilted quote character to encapsulate names, but not strings. To enter a string in the query you will have to use normal quotes like '.
You can to this:
select `someTable`.`someColumn` from `someTable`
but not this:
select someTable.someColumn from someTable where myName=`Tommy`;
The correct use would be:
select someTable.someColumn from someTable where myName='Tommy';
I have an array of values, and one of the values is another array (see below). I implode the inner-array so that it becomes v0,v1,vx and I'm inserting it into a column of a mysql database where the datatype is SET()
a = array(
"first"=>"foo",
"second"=>array("b","a","r"), // this becomes "second"=>"b,a,r",
"third"=>"bang"
)
My question is which PDO::PARAM_* should I use?
(Initially I would think PARAM_STR, but I'm not sure if PDO will do something that won't work with SET()).
PARAM_STR should do the job correctly. It will escape values and add single quotes around comma separated list.
Problem:
one column of a table contains serialized php arrays. i'd like to extract values of that serialized data structure without using php. i'd need a postgres sql statement to get those values.
Example:
here's the part of the serialized datastructure, i'd need (the bold part):
... s:12:"SearchtermID";s:4:"1008"; ....
THANKS!
This will work in your example:
SELECT substring('... s:12:"SearchtermID";s:4:"1008"; ....', 's:4:"([0-9]+)"');
See the manual here and here.
You may want to provide more details ...
This my solution:
select substring((regexp_matches(db_fieldname,'("\d+")','g'))[1] from '"(\d+)"') from db_tablename
