Do OData query supports case-insensitive query similar to SQL?
For example in SQL,
//valid
Select * From Product OrderBy lastupdateddate
Select * From Product OrderBy LastUpdatedDate
While in OData,
//only one of them is valid.
/products?$orderby=lastupdateddate
/products?$orderby=LastUpdatedDate
Invalid endpoint returns error message: "The query specified in
the URI is not valid. Could not find a property named
'lastupdateddate'.
At WebAPI HttpConfiguration:
//add this
config.EnableCaseInsensitive(true);

I'm working on a graphQL backend with TypeORM
I found FREETEXT, CONTAiNS, FREETEXTTABLE and CONTAINSTABLE options for fulltext searching in my SQL database.
As FREETEXTTABLE has a "RANK column, it is more useful and I’m using this option.
I added required settings to the database and by below query it’s working correctly when applying the query directly into the database:
SELECT * FROM content
INNER JOIN freetexttable( content , *, 'test text') newtable ON newtable.[KEY] = "id"
ORDER BY newtable.RANK desc
OFFSET 0 ROWS FETCH NEXT 12 ROWS ONLY
But when I try to use it with TypeORM like below I have some errors.
import { getRepository } from "typeorm";
let repo = getRepository(Content)
return repo.createQueryBuilder("qb")
.innerJoin(FREETEXTTABLE( qb , *, 'light'), newtable,newtable.[KEY] = qb.id)
.skip(0)
.take(12)
.getManyAndCount();
And it returns this error:
"Error: Invalid object name 'FREETEXTTABLE( qb , *, 'light')'."
Could you please let me know if there is a problem with my code or maybe you know a better option for fulltext search in SQL database
I was searching for the same issue. I was unable to find a solution to use FREETEXTTABLE with typeorm, so I had to implement it using raw SQL. using below code
repo.query(" RAW SQL ")
I am using spring boot and spring data JPA with a Postgres database. There is a weird behaviour that happens when query something and the result is nothing.
In a lot of databases and projects when I make a query and the result was empty the returned object to java was null.
For example:
#Query(value = "select * from notification where WEBCODE = :webCode OR USERNAME = :username", nativeQuery = true)
Page<NotificationSQL> getNotificationsAsPage(#Param( "webCode" ) String webCode,#Param( "username" ) String username, Pageable pageable);
In this case I was suppose to get a null page. but in this case I am receiving an exception
org.springframework.dao.InvalidDataAccessResourceUsageException: could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet

I do not understand why it does not just return a null object. It happens the same with the rest of the queries when empty rows and different objects as List classes. In a lot of projects this has not happen to me, the returned object when the query was right and empty rows was a null.
If the parameters are not null it works perfect, but the point is that these parameters sometimes are null and , as it can be seen in the image, the query works nice but with a result of empty rows.
Thanks in advance
I am having a tons of URL's in my database and want to filter them by user-defined string in format something/*/something, where * stands for "anything". So when user defines checkout/*/complete, it means it filters out url's like:
http://my_url.com/checkout/15/complete
http://my_url.com/checkout/85/complete
http://my_url.com/checkout/something/complete
http://my_url.com/super/checkout/something/complete
etc.
How do I do that in SQL? Or should I filter out all the results and use PHP to do the job?
My SQL request now is
SELECT * FROM custom_logs WHERE pn='$webPage' AND id IN ( SELECT MAX(id) FROM custom_logs WHERE action_clicked_text LIKE '%{$text_value_active}%' GROUP BY token ) order by action_timestamp desc
This filters out all the log messages with user-defined text in column action_clicked_text, but uses LIKE statement, which will not work with * inside.
You want like. Either:
where url like '%checkout/%/complete%'
to get the urls that match he pattern. Or:
where url not like '%checkout/%/complete%'
to get the other urls.
Let's suppose I have a table: Person(Name: univarchar) and this table contains a row "abc".
I search Person by using Hibernate (Criteria API and HQL):
Criteria API:
Criteria c = session.createCriteria(Person.class);
c.add(Restrictions.ilike(name,"abc"));
return c.list();
HQL:
String query = "from Person where lower(name) like :name";
Query q = session.createQuery(query);
query.setString("name","abc");
return query.list();
It return empty result. However, when I use Interactive SQL of Sybase to execute SQL statement that is generated by Hibernate, it return a row "abc".
I found a solution for HQL case. This is to use rtrim function:
String query = "from Person where lower(rtrim(name)) like :name";
...
But my problem is I want to use Criteria API and I cannot find any ways to trim name column by using Criteria API.
Thanks and sorry for my poor English.
Have you tried with this code :
Criteria c = session.createCriteria(Person.class);
c.add(Restrictions.ilike(name,"abc",MatchMode.ANYWHERE));
return c.list();
If this will not work then Read this. Its similar Just he wants to trim while Order you want to trim while Restrictions.
From Java I am doing the following query on DB2:
SELECT * FROM PRV_PRE_ACTIVATION WHERE TRANSACTION_ID = ?
The field TRANSACTION_ID is a VARCHAR of length 32. I set the parameter in the preparedStatement using the setString method.
I get the error:
com.ibm.db2.jcc.am.SqlSyntaxErrorException: DB2 SQL Error: SQLCODE=-270, SQLSTATE=42997, SQLERRMC=63, DRIVER=3.59.81

Where the sqstate means "Capability is not supported by this version of the DB2 application requester, DB2 application server, or the combination of the two." But I don't use any strange functionality.
I have tried using an squ client the query:
SELECT * FROM PRV_PRE_ACTIVATION where transaction_id='A'
And it goes ok.
What is the cause of the problem?
UPDATE: The code where the statement is prepared:
s = con.prepareStatement(sSQL,
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_UPDATABLE);
Try changing to a specified list of columns in the select list -- my guess is you have a user defined column type (or some other type) which is not supported by your driver. For example, does the statement
SELECT TRANSACTION_ID FROM PRV_PRE_ACTIVATION WHERE TRANSACTION_ID = ?
work? If so then start adding columns in and you will find the problem column.
I've came across this problem lately, and after some searching on web, I've came across this link:
DB2 SQL error: SQLCODE: -270, SQLSTATE: 42997, SQLERRMC: 63
, which specifies this:
A column with a LOB type, distinct type on a LOB type, or
structured type cannot be specified in the select-list of an
insensitive scrollable cursor.
With help from an colleague, we came to this conclusion:
1, Q: When will you get this "SQLCODE=-204, SQLSTATE=42704" exception?
A: When a scrollable PreparedStatement is prepared & executed, yet there are [B|C]LOB fields exist in the select list. e.g.:
String strQuery = "SELECT NUMBER_FIELD, CHAR_FIELD, CLOB_FIELD FROM TABLE_NAME WHERE CONDITION IS TRUE;"
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, REsultSet.CONCUR_READ_ONLY);
rs = stmt.executeQuery(strQuery); //and this exception will be thrown here
2, Q: So what's the solution if we want to get rid of it when [B|C]LOB fields are queried?
A: Try to use ResultSet.TYPE_FORWARD_ONLY while creating the query statement.e.g.:
stmt = conn.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY);
Or simply try this one:
stmt = conn.createStatement();
Note that the same rules apply to conn.prepareStatement() too. You may refer to Java API doc for more information.
