Class SchemaGenerator

java.lang.Object
  org.apache.openjpa.jdbc.schema.SchemaGenerator

public class SchemaGenerator
extends Object

The SchemaGenerator creates Schemas matching the current database. All schemas are added to the current SchemaGroup. Note that tables whose name starts with "OPENJPA_" will be not be added to the database schema. This enables the creation of special tables that will never be dropped by the SchemaTool.

generateSchemas

public void generateSchemas()
                     throws SQLException

Generate all schemas set in the configuration. This method also calls generateIndexes(java.lang.String, java.lang.String[]), generatePrimaryKeys(java.lang.String, java.lang.String[]), and generateForeignKeys(java.lang.String, java.lang.String[]) automatically.

Throws:

SQLException

generateSchemas

public void generateSchemas(String[] schemasAndTables)
                     throws SQLException

Deprecated.

Throws:

SQLException

generateSchemas

public void generateSchemas(DBIdentifier[] schemasAndTables)
                     throws SQLException

Generate the schemas and/or tables named in the given strings. This method calls generateIndexes(java.lang.String, java.lang.String[]), generatePrimaryKeys(java.lang.String, java.lang.String[]), and generateForeignKeys(java.lang.String, java.lang.String[]) automatically.

Throws:

SQLException

generateSchema

public void generateSchema(String name,
                           String[] tableNames)
                    throws SQLException

Throws:

SQLException

                    throws SQLException

Add a fully-constructed Schema matching the given database schema to the current group. No foreign keys are generated because some keys might span schemas. You must call generatePrimaryKeys(java.lang.String, java.lang.String[]), generateIndexes(java.lang.String, java.lang.String[]), and generateForeignKeys(java.lang.String, java.lang.String[]) separately.
