Here is the sql query :
select a.MATRICULE as id ,
a.MATRIC_SUPERIEUR as pid ,
g.NOM + ' ' +g.prenom as name ,
t.INTITULE as title
from CLASSIFICATION c, AFFECTATION a,AGENT g ,TABLE_REFERENCE t
where a.MATRICULE = g.MATRICULE
and CODE=c.FONCTION
and c.MATRICULE = g.MATRICULE
for json auto
the generated json :
{"id":"1111","pid":"","name":"Hilmi Mehdi","t":[{"title":"Fonction 1"}]}
How to make it like this
{"id":"1111","pid":"","name":"Hilmi Mehdi","title":"Fonction 1"}
I suggest you take a look at this page:
https://learn.microsoft.com/en-us/sql/relational-databases/json/format-query-results-as-json-with-for-json-sql-server?view=sql-server-ver15
It shows a few different ways of going about this (option 1 probably suiting your use case the best).

I'm using a search bar on my website based on keyup binding and ajax requests. It works fine but I would like my search engine to be able to have finner result with multi keywords management.
However I could not find any simple method to set up this kind of search method.
Does anyone knows how to set this up ?
Here is the actual SQL request that's being made:
if ($recherche !=""){
$req = $this->bdd->prepare("SELECT * FROM videos WHERE titre LIKE :recherche OR auteur LIKE :recherche UNION SELECT videos.id_video, videos.titre, videos.lien, videos.auteur, videos.date_upload FROM videos RIGHT JOIN mots_clefs ON videos.id_video = mots_clefs.id_video AND mots_clefs.mot_clef LIKE :recherche ORDER BY date_upload DESC LIMIT ".$start.", ".$limit);
$req->execute(array('recherche' => "%".$recherche."%"));
$result = json_encode($req->fetchAll(PDO::FETCH_ASSOC));
}
Request example:
SELECT * FROM videos WHERE titre LIKE '%word 1 word 2%' OR auteur LIKE '%word 1 word 2%' UNION SELECT videos.id_video, videos.titre, videos.lien, videos.auteur, videos.date_upload FROM videos RIGHT JOIN mots_clefs ON videos.id_video = mots_clefs.id_video AND mots_clefs.mot_clef LIKE '%word 1 word 2%' ORDER BY date_upload DESC LIMIT 0, 20);
You can execute the above query in a loop by passing one keyword at a time.
get the entire keyword list provided by the user into a sting.
Use string.Split() method by passing comma(,) as delimiter to get the list of the keywords into an array list.
loop through the array list and pass to the query.
Make sure you append the data fetched from the SQL into a data table or dataset and Not rewrite it.
string select = "SELECT * FROM [MyTable] WHERE [Title] LIKE '%" + strSearch.Replace(",", "%' OR [Title] LIKE '%") + "%'";
I have the following code :
SELECT Description FROM KeysDB WHERE Count='0 (Blocked)' OR ErrorCode='0xC004C060' AND Description LIKE '%Win%'
It works normally until I change it.
SELECT Description FROM KeysDB WHERE Count='0 (Blocked)' OR ErrorCode='0xC004C003' OR ErrorCode='0xC004C060' AND Description LIKE '%Win%'
I want to select all Windows product key with Count = 0 (Blocked) or ErrorCode = 0xC004C060 or ErrorCode = 0xC004C003
and / or have different operator precedence. That means their binding strength is differently.
You can use parentheses to make it how you like. Not sure if this is how you intended it but you get the picture:
SELECT Description
FROM KeysDB
WHERE
(
Count='0 (Blocked)' OR ErrorCode='0xC004C003' OR ErrorCode='0xC004C060'
)
AND Description LIKE '%Win%'
lets say have column with values
"Html", "Java", "JQuery", "Sqlite"
and if user enters
"Java is my favorite programming language"
then result should be
1 row selected with value "Java"
because entered sentence starts with "Java"
but if user enters
"My application database is in Sqlite"
then query should return empty.
0 row selected
because entered sentence does not start with "Sqlite".
I am trying following query:
SELECT * FROM demo where 'Java' like demo.name; // work
but if enter long text then it fails
SELECT * FROM demo where 'Java is my favorite programming language' like demo.name; // Fails
I think you want something like this :
SELECT * FROM demo WHERE yourText LIKE demo.name || '%' ;
Just put the column name on the left side of the like operator, and concatenate a wildcard at the right side of your string keywork:
select * from demo where name like 'Java%' ; -- or like 'Sqlite%' etc
You can make it more generic like:
select * from demo where name like ? || %' ;
where ? is a bind parameter that represents the value provided by the user (you may also concatenate with the wildcard in your application before passing the parameter).
Concatenate your column with a wildcard:
SELECT * FROM demo where 'Java is my favorite programming language' like demo.name || '%';
You can make your query like this
Select * from SearchPojo where name GLOB '*' || :namestring|| '*'"
Not sure if I got the problem but ...
You can query these values (Html, Java, JQuery, Sqlite) put them in a collection, like List, then grab user's input and check it:
List<String> values ... // Html, Java, JQuery, Sqlite
for (String value : values) {
if (userInput.contains(value) {
// print
System.out.println("1 row selected with value \"Java\");
}
}
It supports cases where user type more then one option.
I am getting array from front end to perform filters according that inside the SQL query.
I want to apply a LIKE filter on the array. How to add an array inside LIKE function?
I am using Angular with Html as front end and Node as back end.
Array being passed in from the front end:
[ "Sports", "Life", "Relationship", ...]
SQL query is :
SELECT *
FROM Skills
WHERE Description LIKE ('%Sports%')
SELECT *
FROM Skills
WHERE Description LIKE ('%Life%')
SELECT *
FROM Skills
WHERE Description LIKE ('%Relationship%')
But I am getting an array from the front end - how to create a query for this?
In SQL Server 2017 you can use OPENJSON to consume the JSON string as-is:
SELECT *
FROM skills
WHERE EXISTS (
SELECT 1
FROM OPENJSON('["Sports", "Life", "Relationship"]', '$') AS j
WHERE skills.description LIKE '%' + j.value + '%'
)
Demo on db<>fiddle
As an example, for SQL Server 2016+ and STRING_SPLIT():
DECLARE #Str NVARCHAR(100) = N'mast;mode'
SELECT name FROM sys.databases sd
INNER JOIN STRING_SPLIT(#Str, N';') val ON sd.name LIKE N'%' + val.value + N'%'
-- returns:
name
------
master
model
Worth to mention that input data to be strictly controlled, since such way can lead to SQL Injection attack
As the alternative and more safer and simpler approach: SQL can be generated on an app side this way:
Select * from Skills
WHERE (
Description Like '%Sports%'
OR Description Like '%Life%'
OR Description Like '%Life%'
)
A simple map()-call on the words array will allow you to generate the corresponding queries, which you can then execute (with or without joining them first into a single string).
Demo:
var words = ["Sports", "Life", "Relationship"];
var template = "Select * From Skills Where Description Like ('%{0}%')";
var queries = words.map(word => template.replace('{0}', word));
var combinedQuery = queries.join("\r\n");
console.log(queries);
console.log(combinedQuery);
My final goal is I want to get plid and portletId that can be display my article(or entry with any type if it is possible).
I have sql query that return me any portlet availble for display my article.
But when I have to use dynamicQuery to get the same results, I get problem with xPath and array comparison, please help!
SELECT * FROM portletpreferences pr
WHERE pr.preferences != '<portlet-preferences />' AND pr.ownerid = 0 AND pr.portletid ilike '%_INSTANCE_%' AND pr.plid IN(
SELECT layout.plid FROM layout
WHERE layout.type_ = 'portlet' AND layout.groupid = 19 AND layout.hidden_ is false)
AND pr.portletpreferencesid IN (
SELECT pr.portletpreferencesid FROM portletpreferences pr
WHERE 'true' = ANY(xpath('//preference[name="anyAssetType"]/value/text()', XMLPARSE(DOCUMENT pr.preferences))::text[])
OR (SELECT (array(SELECT id_ FROM journalstructure))::text[]) && xpath('//preference[name="classTypeIds"]/value/text()', XMLPARSE(DOCUMENT pr.preferences))::text[] )
If you are bent upon using this same query, then use this query directly with Custom-SQL in liferay by creating custom-finders instead of using DynamicQuery. That would give you a lot of flexibility in using any type of SQL query directly.
I don't think this query can be converted to DynamicQuery, but if you do manage to convert it then please do post it here :-)
DynamicQuery is very powerful, see e.g. my answer how to find layouts with specific JournalArticles. I think your requirement is similar to this one:
Liferay: How to find all Layouts with the specific JournalArticle in AssetPublisher portlets?
