Examples of org.hsqldb.scriptio.ScriptWriterText

org.hsqldb.scriptio.ScriptWriterText
Handles all scripting and logging operations. A script consists of two blocks:
DDL: SQL statements for table and user definitions DATA: INSERT statements for memory tables This happens as part of the CHECKPOINT and SHUTDOWN COMPACT process. In this case, the DATA block contains the CACHED table data as well.
A related use for this class is for saving a current snapshot of the database data to a user-defined file with the SCRIPT command A log consists of SQL statements of different types. Each statement is encoded as ASCII and saved. @author Fred Toussi (fredt@users dot sourceforge.net) @version 1.9.0 @since 1.7.2
