Constraint names cannot be quoted with backticks ` -------------------------------------------------- Key: HHH-3772 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3772 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1 Environment: Hibernate 3.3, all database dialects Reporter: Christian Priority: Minor Table and Column names can be quoted with ` but constraint names cannot be quoted. You can reproduces the bug with the following testcase: @javax.persistence.Entity @javax.persistence.Table( name = "`categories`" ) abstract public class Category { ... @org.hibernate.annotations.ForeignKey( name = "`fk_categories_parent_id`" ) @javax.persistence.ManyToOne( targetEntity = Category.class ) @javax.persistence.JoinColumn( name = "`parent_id`" ) private Category parent; ... } The SchemaExport (hbm2ddl) creates the following SQL statement for Postgresql: alter table "categories" drop constraint `fk_categories_parent_id`; drop table "categories"; create table "categories" ( ... "parent_id" int8, ... ); alter table "categories" add constraint `fk_categories_parent_id` foreign key ("parent_id") references "categories"; I think this problem should be fixed in the method in the class org.hibernate.mapping.Constraint in the same way as in Table.java and Column.java: old: public void setName(String name) { this.name = name; } new: private boolean quoted = false; public void setName(String name) { if ( name.charAt( 0 ) == '`' ) { quoted = true; this.name = name.substring( 1, name.length() - 1 ); } else { this.name = name; } } public String getQuotedName() .. same as in Column.java public String getQuotedName(Dialect d) { .. same as in Column.java public boolean isQuoted() .. same as in Column.java public String sqlDropString( ... ) { ... return "alter table " + getTable().getQualifiedName( dialect, defaultCatalog, defaultSchema ) + " drop constraint " + getQualifiedName(); ... } public String sqlCreateString( ... ) { ... String constraintString = sqlConstraintString( dialect, getQualifiedName(), defaultCatalog, defaultSchema ); ... } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
