How to get fully materialized query from querydsl

Question

I am trying to use querydsl for building dynamic queries for dynamic schemas. I am trying to get just the query instead of having to actually execute it.

So far I ha

To enable schema printing use the following pattern

SQLTemplates templates = MySQLTemplates.builder()
    .printSchema()
    .build();

SQLTemplates subclasses were used before, but since some time the builder pattern is the official way to customize the templates http://www.querydsl.com/static/querydsl/3.3.1/reference/html/ch02s03.html#d0e904

And to enable direct serialization of literals use

//configuration level
configuration.setUseLiterals(true);

//query level
configuration.setUseLiterals(true);

Here is a full example

// configuration
SQLTemplates templates = MySQLTemplates.builder()
    .printSchema()
    .build();
Configuration configuration = new Configuration(templates);

// querying
SQLQuery sqlQuery = new SQLQuery(connection, configuration)
    .from(userPath).where(idPath.eq(1l)).limit(10);
sqlQuery.setUseLiterals(true);    
String query = sqlQuery.getSQL(usernamePath).getSQL();

If you always just want the SQL query string out, move setUseLiterals from query to configuration.

Concerning the usage of Querydsl expressions the usage of code generation like documented here is advised http://www.querydsl.com/static/querydsl/3.3.1/reference/html/ch02s03.html

It will make your code typesafe, compact and readable.

If you want to try Querydsl without code generation you can replace
