Class ScriptWriterText

java.lang.Object

org.hsqldb.scriptio.ScriptWriterBase

org.hsqldb.scriptio.ScriptWriterText

All Implemented Interfaces:

java.lang.Runnable

Direct Known Subclasses:

ScriptWriterEncode

public class ScriptWriterText
extends ScriptWriterBase

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.

Since:

1.7.2
