Original close reason(s) were not resolved
def concatField =

match concatField !contains expected
*But I get an error: "net.minidev.json.parser.parseexception unexpected character ( })" at position 66."
Is there another way to define this concatenated field without writing a java utility?*
No, unfortunately there is no other way.

What is the meaning of <> in mysql query?
(7 answers)
Closed 3 years ago.
I know this is a really beginner question, but I don't know what the meaning of this. I'm reading the existing system code. I don't know what does this symbol means <> in Query Builder.
Here is the sample code:
$builder = DB::table('product');
if (isset($product->type)) {
$builder->where('product.type', '<>', $product->type);
}
Thanks!
In MySQL syntax, this is the same as not equal or !=.

I have found some similar questions, but unfortunately the examples were too complicated for me to comprehend.

Split Function equivalent in tsql?
I have a column that contains data in the form:
CustomerZip::12345||AccountId::1111111||s_Is_Advertiser::True||ManagedBy::3000||CustomerID::5555555||
Does SQL have any sort of built in function to easily parse out this data, or will I have to build my own complicated mess of patindex/substring functions to pull each value into its own field?
I don't believe there is anything built in. Look at the comments posted against your original question.
If this is something you're going to need on a regular basis, consider writing a view.

How to search for a comma separated value
(3 answers)
Closed 8 years ago.
I have data in table in below format
id brand_ids
--------------
2 77,2
3 77
6 3,77,5
8 2,45,77
--------------
(Note the brand ids will be stored like comma separated values, this is common for values in this field)
Now i am trying to get a query which is capable of querying out only rows which have '77'
in it..
I know i can use LIKE command in three formats LIKE '77,%' OR LIKE '%,77,%' OR LIKE '%,77' with or condition to achieve it. But i hope this will increase the load time of the sql.
is there any straight forward method to achieve this? if so please suggest.
Thanks,
Balan
A strict answer to your question would be: no. Your suggestion of using LIKE is your best option with this data model. However, as mentioned, it is highly suggested that you use a more normalized model.
