 String dbVendorName,
 OutputStream createDDLSql,
 OutputStream dropDDLSql,

 OutputStream createDDLJdbc,

Generate DDL from schema and database vendor name. Up to four files containing DDL are created:

• create table DDL destined for human readers
• create table DDL destined for a JDBC connection
• drop table DDL destined for human readers
• drop table DDL destined for a JDBC connection

Furthermore, if the datbase output stream is not null, then create tables in database.

Parameters:

schema - Database schema for which DDL is generated.

dbVendorName - Name of database vendor, which must match one of the names of the .properties files in this package.

createDDLSql - An OutputStream to which human-readable DDL for creating tables gets written.

dropDDLSql - An OutputStream to which human-readable DDL for dropping tables gets written.

dropDDLJdbc - An OutputStream to which DDL for dropping tables gets written. This parameter differs from dropDDLSql because the data written into it is supposed to be used with a JDBC connection.

createDDLJdbc - An OutputStream to which DDL for creating tables gets written. This parameter differs from createDDLSql because the data written into it is supposed to be used with a JDBC connection.

dbStream - DatabaseOutputStream which, if not null, is used to create tables in a live database during this method call.

dropAndCreateTbl - If true, and dbStream is not null, then existing tables are dropped before new ones are created.

Throws:

org.netbeans.modules.dbschema.DBException

SQLException

IOException
