Use single quotes and "()" not "[]".
select *
from states
where status in ('Cancelled', 'Won')
limit 1000

(Background on this error at: http://sqlalche.me/e/13/f405)
Hello,
I can't get this query to pull the Country Area names where the Per capita Income is less than 11000. what is wrong with my query? I am using Jupyter Notebooks and my database is DB2. Please help. thanks!
Background
Framework: Codeignighter/PyroCMS
I have a DB that stores a list of products, I have a duplicate function in my application that first looks for the common product name so it can add a 'suffix' value to the duplicated product.
Code in my Products model class
$product = $this->get($id);
$count = $this->db->like('name', $product->name)->get('products')->num_rows();
$new_product->name = $product->name . ' - ' . $count;
On the second line the application fails only when the $product->name contains quotes.
I was with the understanding that Codeignighter escaped all strings so I dont know why I get this error.
So I tried to use MySQL escape string function but that didn't help either.
The Error Message
A Database Error Occurred
Error Number: 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 's Book%'' at line 3
SELECT * FROM `products` WHERE `name` LIKE '%Harry\\'s Book%'

Below is the output of doing a var_dump on product->name before and after the line in question;
string 'Harry's Book' (length=12)
A Database Error Occurred
Error Number: 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 's Book%'' at line 3
SELECT * FROM `products` WHERE `name` LIKE '%Harry\\'s Book%'
Let's do some testing about this.
Here is what you are doing
$count = $this->db->like('name', $product->name)->get('products')->num_rows();
And i suspect $product->name contains this.
Harry's Book
As we know this is coming from the database table as you are using.
Where you are using the upper query mentioned it is wrapping it with
single quotes and producing this result.
SELECT * FROM `products` WHERE `name` LIKE '%Harry\\'s Book%'
As you see it is escaping apostrophy to tell it is not end of string
Therefore escaping it with two slashes.One for apostrophy and one for being in single quote.
What you have to do is
Before assigning the parameter to query wrap it with double quotes.
$product_name = "$product->name";
And now pass it to query.
$count = $this->db->like('name', $product_name)->get('products')->num_rows();
The output will be this
SELECT * FROM `products` WHERE `name` LIKE '%Harry\'s Book%'
You see the differece here. It contains single slash now and the record will
be found.
Other answers didn't work for me, this does though:
$count = $this->db->query("SELECT * FROM `default_firesale_products` WHERE `title` LIKE '".addslashes($product['title'])."'")->num_rows();
Whenever CI Active Record mangles your queries you can always just put a raw query in instead and have full control.
Try this, using stripslashes() around $product->name:
$count = $this->db->like('name', stripslashes($product->name))->get('products')->num_rows();
CI automatically escapes characters with active records but I bet that it's already escaped if you entered it previously via active record in CI. So now it is doing a double escape.
Update: You may also want to try adding the following before you query:
$this->db->_protect_identifiers = FALSE;
Last try: try querying this way since it seems like the like active record is causing the error:
$like = $product->name;
$this->db->query("SELECT * FROM `products` WHERE `name` LIKE '%$like%'");
Using Advantage Database Server 8.1 I am having trouble executing a successful query. I am trying to do the following
SELECT * FROM Persons
WHERE LastName IN ('Hansen','Pettersen')
To check for multiple values in a column. But I get an error when I try to execute this query in Advantage.
Edit - Error
poQuery: Error 7200: AQE Error: State = 42000; NativeError = 2115; [iAnywhere Solutions][Advantage SQL Engine]Expected lexical element not found: ( There was a problem parsing the
WHERE clause in your SELECT statement. -- Location of error in the SQL statement is: 46
And here is the SQL i'm executing
select * from "Pat Visit" where

'98962', '99078')
Done
Does anyone have any Idea how I could do something similar in advantage that would be efficient as well?
Thanks
You have an extraneous = in the statement after the IN. It should be:
select * from "Pat Visit" where
DIAG1 IN ('43644', '43645', <snip> )
I have an error with this sentence:
...
WHERE title LIKE '%$title%' OR text LIKE '%$title%'
AND (price BETWEEN $minprice AND $maxprice)
AND catid = $catid ORDER BY id DESC
Error:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'AND ) AND cat' at line 34
I did something wrong?
Evaluating "$maxprice" gives an empty string, probably because the variable $maxprice it is not defined. It could be a typo, or that you forgot to set a value for this variable.
Check your $maxprice Variable - it seems to be empty.
what is wrong with this sql query. i cant figure it out.
$query = "SELECT *
FROM tagPairs
WHERE (tag1Id IN ($tag1Id, $tag2Id))
AND (tag2Id IN ($tag1Id, $tag2Id))";
error code:
Couldn't execute query: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' ))
AND (tag2Id IN (, ))' at line 3
thanks in advance!
$tag1Id and $tag2Id are both null, or empty strings. The simplest solutions is probably to explicitly cast them into numerical values:
$tag1Id = intval($tag1Id);
$tag2Id = intval($tag2Id);
$query = "SELECT *
FROM tagPairs
WHERE (tag1Id IN ($tag1Id, $tag2Id))
AND (tag2Id IN ($tag1Id, $tag2Id))";
$tag1Id and $tag2Id are empty.
That's why your error says (tag2Id IN (, )).
Your $tag1Id and $tag2Id are empty strings. Assign a value to them and it should work fine.
Also, selecting * is a bad idea. Select the columns you need explicity.
