Constructor Details

DdlWrite

public DdlWrite()

Create without any configuration or current model (no history support).

DdlWrite

public DdlWrite(MConfiguration configuration,
 ModelContainer currentModel,
 DdlOptions options)

Create with a configuration.

Method Details

getOptions

public DdlOptions getOptions()

Return the DDL options.

getTable

public MTable getTable(String tableName)

Return the Table information from the current model.

This is typically required for the history support (used to determine the list of columns included in the history when creating or recreating the associated trigger/stored procedure).

isApplyEmpty

public boolean isApplyEmpty()

Return true if the apply buffers are all empty.

apply

public DdlBuffer apply()

Return the buffer that APPLY DDL is written to.

applyDropDependencies

public DdlBuffer applyDropDependencies()

Return the buffer that executes early to drop dependencies like views etc.

applyForeignKeys

public DdlBuffer applyForeignKeys()

Return the buffer that APPLY DDL is written to for foreign keys and their associated indexes.

Statements added to this buffer are executed after all the normal apply statements and typically 'add foreign key' is added to this buffer.

applyHistoryView

public DdlBuffer applyHistoryView()

Return the buffer that apply history-view DDL is written to.

applyHistoryTrigger

public DdlBuffer applyHistoryTrigger()

Return the buffer that apply history-trigger DDL is written to.

dropAllForeignKeys

public DdlBuffer dropAllForeignKeys()

Return the buffer used for the 'drop all DDL' for dropping foreign keys and associated indexes.

dropAll

public DdlBuffer dropAll()

Return the buffer used for the 'drop all DDL' to drop tables, views and history triggers etc.
