I want to write JPQL, which returns all my entities. The problem is that entity is called "Case", and this is a restricted word. Does JPQL has some escape characters? How to write this JPQL?
SELECT c from Case
Thanks in advance for help.

I have data coming from html contact form which i am sending in a email through a java webservice. Everything is working fine but when user inserts data containing apostrophe (single quote) insert fails.
Pls help me to understand How and where to handle this data.
TIA
You just need to use Prepared Statements,it will escape special characters and avoid SQL_injection
You can use Prepared Statements, and you can just escape all special characters like single quote, double quote etc. before inserting in the database.
I'm facing a non usual issue while using criterias. I want to do a criteria with a like clause but the text contains special chars like the bracket char "[" and it seems that it's a special char in MSSQL database.
From an sql query I must use the special wording ESCAPE see example :
AND file1.FILE_NAME like '%[Main profile picture]%' **ESCAPE '['**
But I dont know how I can do the same using criteria. I'm currently using this clause temporarily :
criteria.add(Restrictions.like("files.fileName", "%Main profile picture%"));
but that's not what I want I really need to escape the '[' char.
Can somebody help me with this please...?
Thank you for your help!
I have a table name Order and since it is a reserved word in Hibernate, it is not letting me to construct desired query. Is there any way by which I can escape table name in HQL?
I got across similar question asking for alias How to escape reserved words in Hibernate's HQL
But this solution is not working for me. Is there any other way by which we can do this? I am using version 4.3 of hibernate.
Have you mapped the table to an entity that is also called Order? If so then I'd suggest renaming the entity as there as the Hibernate team appear to have rejected the request to add keyword escaping to HQL. If the problem is actually with the generated SQL then you can add backticks to the table name to escape it according to the database dialect that is in use.
I am trying to escape a whole string for insert into a longtext or varchar. Basically I have a string full of all types of special characters and special words (ex. LIKE) and I just want to escape the whole thing so that I can insert it into my H2 database.
I've asked a few friends and they said that I should try serializing the data. Is this the proper way to insert random strings into the db? Should I be trying to do this with prepared statements?
Sorry I'm new to H2 and not that great with SQL. Thanks for the help in advance!
If you are looking for examples on how to use a PreparedStatement:
http://docs.oracle.com/javase/tutorial/jdbc/basics/prepared.html
http://en.wikipedia.org/wiki/Prepared_statement#Examples
http://www.jdbc-tutorial.com/jdbc-prepared-statements.htm
Use a PreparedStatement and pass the string as a parameter.
I would like to have an entity named "GROUP" in my JPA setup. Now I get problems when I try to perform JPA queries, like "select count(group_.id) from Group group_".
JPA thinks this is a misplaced GROUP BY attempt and complains. Is there a way I can escape "Group", or do I have to rename my table?
Thx!
please don't do it!
rename your table to something else, you'll thank me in the long run. Don't use any reserved words for table or column names!
name it something like EmployeeGroup, JobGroup or ObjectGroup, etc...
