[Solved] Eclipselink 2.5 + MSSQL (jtds) escaping table names [message #1140383]

Hello,

I've noticed that Eclipselink automatically escapes table names in MSSQL also. BUT it will escape the table names in double quotes.

As far as I know this is the source of my problem : [dbo].[table name] should work, while "[dbo]"."[table name]" does not.

It could be something else, but I want to try this first. How would I turn off automatic escaping in double quotes? Actually, even better would be if it escaped names using [] instead of double quotes no? When user sets property <property name="eclipselink.target-database" value="SQLServer"/> for example?

It should not escape table names by default, so check your settings - specifically for a delimited-identifiers tag in an orm.xml file, or that the table name definitions do not include '/"' escapes. The " delimiter is the default on DatabasePlatform, and can be changed using the setStartDelimiter and setEndDelimiter methods via a session customizer http://wiki.eclipse.org/EclipseLink/UserGuide/JPA/Advanced_JPA_Development/Customizers

Not sure why I had to do this, having specified MSSQL as my platform... at least it works fine now. Had to dig a bit more though but thanks for the correct pointers Smile

public class DatabaseCustomizer implements SessionCustomizer {

	public void customize(Session session) {
		DatasourcePlatform platform = session.getPlatform();
		platform.setStartDelimiter("[");
		platform.setEndDelimiter("]");
	}
}

And persistence.xml

<persistence-unit>
   <persistence>
...
      <properties>
         <property name="eclipselink.target-database" value="SQLServer"/>
         <property name="eclipselink.session.customizer" value="si.result.internal.ure.service.data.customizer.DatabaseCustomizer"/>
      </properties>
...
   </persistence-unit>
</persistence>
