kandi X-RAY | QueryBuilder Summary
QueryBuilder is a fluent library for building SELECT statements for SQLite. It creates parameterized queries by default, but you can also get the query string without parameters by using the toDebugSqlString method. QueryBuilder also uses the excelent JODA-Time library (to handle dates. I strongly advise you to use this library instead of using the built-in Date and Time classes from Java. Version 2.1 is included in the libs folder, but feel free to use the latest version available. By default, QueryBuilder assumes that dates are stored in the yyyy-MM-dd format, and that datetimes are stored in the yyyy-MM-dd HH:mm:ss format. You can change the default formats by using the QueryBuilderConfiguration class. You can also change the format for a specific QueryBuilder instance, overriding the defaults.

QUESTION
DSE version: 6.7
As the below code was working fine for DSE java driver version : 1.8.2 with the below code
Statement selectQuery = QueryBuilder.select().all().from(table) .where(**QueryBuilder.eq**("solr_query", "{"q":"createdat:[2021-10-15T14:03:37.817Z TO 2021-12-15T07:23:14.025Z]","sort":"updatedate desc", "paging":"driver"}")) .setConsistencyLevel(ConsistencyLevel.valueOf("LOCAL_ONE")); ResultSet rs= super.getManager().getSession().execute(selectQuery);
upgrading to DSE java drivers version : 4.13.0 query is:-
Select selectQuery = selectFrom(table).all().whereColumn("solr_query").isEqualTo(literal("{"q":"createdat:[2021-10-15T14:03:37.817Z TO 2021-12-15T07:23:14.025Z]","sort":"updatedate desc", "paging":"driver"}")); SimpleStatement statement = selectQuery.build().setConsistencyLevel(DefaultConsistencyLevel.valueOf("LOCAL_ONE")); ResultSet rs = this.session.execute(statement );
*--> Giving below exception :
com.datastax.oss.driver.api.core.servererrors.InvalidQueryException: Error on shard 12.345.678.90: Field cache is disabled, set the field=updatedate to be docValues=true and reindex. Or if the field cache will not exceed the heap usage, then place useFieldCache=true in the request parameters.
I am not sure how to address this.
...ANSWER
Answered 2021-Dec-15 at 15:08So in looking at the error message...
set the
field=updatedate
to bedocValues=true
and reindex.
Just wondering, but have you tried this? This should be a good first step.
QUESTION
I'm quite new to ElasticSearch. I'm working on a project where we need to search for an object (Offer) that contains a Set of two (OfferTranslation). The goal is to make research based on some of Offer fields, but also a lot of OfferTranslation fields. Here's a minified version of both classes :
Offer.class (note that I annotated the Set with @Field(type= FieldType.Nested) so i can make Nested queries, as mentionned in the official doc) :
...ANSWER
Answered 2021-Nov-22 at 17:12How was the index mapping created? It does not look like Spring Data Elasticsearch wrote this mapping. The nested type of offerTranslations
is missing as you saw and the text fields have a .keyword
subfield. This looks like data was inserted into the index without having a mapping defined and so Elasticsearch did an automatic mapping. In this case, the values of the @Field
annotations are not used.
You need to have Spring Data Elasticsearch create the index with the mapping. This will happen automatically if the index does not exists and you are using Spring Data Elasticsearch repositories, or you need to use the IndexOperations.createWithMapping
function in your application.
Another thing I noticed: it seems you are using the same entity class for different Spring Data stores, mixing heavily the annotations. You should use different entities for different stores.

QUESTION
I am trying to generate a RawQuery using SupportSQLiteQueryBuilder and it worked well but when I tried adding the selection method for generating a WHERE condition it just doesn't work.
Referred the docs from here: https://developer.android.com/reference/androidx/sqlite/db/SupportSQLiteQueryBuilder#selection(java.lang.String,%20java.lang.Object[]) and found out that the method takes in two arguments.
- The column name (for the WHERE condition)
- The value
Tried it but somehow, the second argument i.e bindArgs array is not added to the query
The query I want:
SELECT * FROM plants WHERE plantOrigin = "Japan"
The query being generated:
SELECT * FROM plants WHERE plantOrigin
Tried this answer https://stackoverflow.com/a/56780629/8442557 but still couldn't get the desired results.

...ANSWER
Answered 2021-Nov-08 at 15:12The documentation for SupportSQLiteQueryBuilder
is limited. 😞
For selection()
, the first parameter is the actual WHERE
clause content, minus the WHERE
keyword, and using ?
where any arguments should go. So, in your case, that would be plantOrigin = ?
.
Then, if you use selection()
, you need to use the query returned by create()
completely. That contains both the generated SQL and the second parameter that you passed to selection()
. In your case, you were just extracting the generated SQL, which means that you lost your plant origin value to use in place of the ?
.

Install QueryBuilder
You can use QueryBuilder like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the QueryBuilder component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
