Using HSQL MEMORY TABLE with grails

Question

是否可以在grails中定义某种映射，以便针对特定grails域将CREATE TABLE替换为CREATE MEMORY TABLE ？

Answer 1

If you wanted to do this for all tables, you could create a custom Dialect and override getCreateTableString() but there's no way to know the current table name, so it can be selectively applied.

But you can take the approach I suggested here: grails limited table creation . You would just override generateSchemaCreationScript() and if you find the table(s) you're looking for, you can replace the 'create table' string with 'create memory table'.

Answer 2

The create table statements are generated by Hibernate's hbm2ddl feature. I don't think there is a way to configure the syntax of the create statement other than the table name itself and the columns.

You would have to manually manage the schema creation using a plugin like Autobase or Liquibase (or whatever they have coming in Grails 1.4 to handle DB migrations).
