Constructor Detail

Db2DbSupport

public Db2DbSupport()

Creates support for Db2 databases.

Method Detail

getTableNames

public Set<String> getTableNames()

Returns the names of all tables in the database.

TODO check table types A = Alias G = Global temporary table H = Hierarchy table L = Detached table N = Nickname S = Materialized query table T = Table (untyped) U = Typed table V = View (untyped) W = Typed view

Specified by:

getTableNames in class DbSupport

Returns:

The names of all tables in the database

getColumnNames

public Set<String> getColumnNames(String tableName)

Gets the names of all columns of the given table.

Specified by:

getColumnNames in class DbSupport

Parameters:

tableName - The table, not null

Returns:

The names of the columns of the table with the given name

getViewNames

public Set<String> getViewNames()

Retrieves the names of all the views in the database schema.

TODO check view types V = View (untyped) W = Typed view

Specified by:

getViewNames in class DbSupport

Returns:

The names of all views in the database

getSequenceNames

public Set<String> getSequenceNames()

Retrieves the names of all the sequences in the database schema.

Overrides:

getSequenceNames in class DbSupport

Returns:

The names of all sequences in the database

getTriggerNames

public Set<String> getTriggerNames()

Retrieves the names of all the triggers in the database schema.

Overrides:

getTriggerNames in class DbSupport

Returns:

The names of all triggers in the database

getTypeNames

public Set<String> getTypeNames()

Retrieves the names of all the types in the database schema.

Overrides:

getTypeNames in class DbSupport

Returns:

The names of all types in the database

disableReferentialConstraints

public void disableReferentialConstraints()

Disables all referential constraints (e.g. foreign keys) on all table in the schema

Specified by:

disableReferentialConstraints in class DbSupport

disableReferentialConstraints

protected void disableReferentialConstraints(String tableName)

disableValueConstraints

public void disableValueConstraints()

Disables all value constraints (e.g. not null) on all tables in the schema

Specified by:

disableValueConstraints in class DbSupport

disableValueConstraints

protected void disableValueConstraints(String tableName)

getSequenceValue

public long getSequenceValue(String sequenceName)

Returns the value of the sequence with the given name.

Note: this can have the side-effect of increasing the sequence value.

Overrides:

getSequenceValue in class DbSupport

Parameters:

sequenceName - The sequence, not null

Returns:

The value of the sequence with the given name

incrementSequenceToValue

public void incrementSequenceToValue(String sequenceName,
                                     long newSequenceValue)

Sets the next value of the sequence with the given sequence name to the given sequence value.

Overrides:

incrementSequenceToValue in class DbSupport

Parameters:

sequenceName - The sequence, not null

newSequenceValue - The value to set

getIdentityColumnNames

public Set<String> getIdentityColumnNames(String tableName)

Gets the names of all identity columns of the given table.

todo check, at this moment the PK columns are returned

Overrides:

getIdentityColumnNames in class DbSupport

Parameters:

tableName - The table, not null

Returns:

The names of the identity columns of the table with the given name

incrementIdentityColumnToValue

public void incrementIdentityColumnToValue(String tableName,
                                           String identityColumnName,
                                           long identityValue)

Increments the identity value for the specified identity column on the specified table to the given value. If there is no identity specified on the given primary key, the method silently finishes without effect.

Overrides:

incrementIdentityColumnToValue in class DbSupport

Parameters:

tableName - The table with the identity column, not null

identityColumnName - The column, not null

identityValue - The new value

Returns:

True

supportsTypes

public boolean supportsTypes()

Types are supported

Overrides:

supportsTypes in class DbSupport

Returns:

true
