Examples with SchemaDropper org.hibernate.tool.schema.spi.SchemaDropper used on opensource projects

Example 1 with SchemaDropper

use of org.hibernate.tool.schema.spi.SchemaDropper in project hibernate-orm by hibernate.

the class SchemaToolTransactionHandlingTest method testDropCreateDropInExistingJtaTransaction.

// for each case we want to run these tool delegates in a matrix of:
// 1) JTA versus JDBC transaction handling
// 2) existing transaction versus not
// 
// cases:
// 1) create-drop
// 2) update
// 3) validate
// 
// so:
// 1) create-drop
// 1.1) JTA transaction handling
// 1.1.1) inside an existing transaction
// 1.1.2) outside any transaction
// 1.1) JDBC transaction handling
// - there really cannot be an "existing transaction" case...
