public InterbaseModelReader(Platform platform)

Creates a new model reader for Interbase databases.

Parameters:

platform - The platform that this model reader belongs to

Method Detail

readTable

protected Table readTable(DatabaseMetaDataWrapper metaData,
              Map values)
                   throws SQLException

Reads the next table from the meta data.

Overrides:

readTable in class JdbcModelReader

Parameters:

metaData - The database meta data

values - The table metadata values as defined by JdbcModelReader.getColumnsForTable()

Returns:

The table or null if the result set row did not contain a valid table

Throws:

SQLException

readColumns

protected Collection readColumns(DatabaseMetaDataWrapper metaData,
                     String tableName)
                          throws SQLException

Reads the column definitions for the indicated table.

Overrides:

readColumns in class JdbcModelReader

Parameters:

metaData - The database meta data

tableName - The name of the table

Returns:

The columns

Throws:

SQLException

determineExtraColumnInfo

protected void determineExtraColumnInfo(Table table)
                                 throws SQLException

Helper method that determines extra column info from the system tables: default value, precision, scale.

Parameters:

table - The table

Throws:

SQLException

determineAutoIncrementColumns

protected void determineAutoIncrementColumns(Table table)
                                      throws SQLException

Helper method that determines the auto increment status using Interbase's system tables.

Parameters:

table - The table

Throws:

SQLException

adjustColumns

protected void adjustColumns(Table table)

Adjusts the columns in the table by fixing types and default values.

Parameters:

table - The table

readPrimaryKeyNames

protected Collection readPrimaryKeyNames(DatabaseMetaDataWrapper metaData,
                             String tableName)
                                  throws SQLException

Retrieves the names of the columns that make up the primary key for a given table.

Overrides:

readPrimaryKeyNames in class JdbcModelReader

Parameters:

metaData - The database meta data

tableName - The name of the table from which to retrieve PK information

Returns:

The primary key column names

Throws:

SQLException

readForeignKeys

protected Collection readForeignKeys(DatabaseMetaDataWrapper metaData,
                         String tableName)
                              throws SQLException

Retrieves the foreign keys of the indicated table.

Overrides:

readForeignKeys in class JdbcModelReader

Parameters:

metaData - The database meta data

tableName - The name of the table from which to retrieve FK information

Returns:

The foreign keys

Throws:

SQLException

isInternalPrimaryKeyIndex

protected boolean isInternalPrimaryKeyIndex(DatabaseMetaDataWrapper metaData,
                                Table table,
                                Index index)
                                     throws SQLException

Tries to determine whether the index is the internal database-generated index for the given table's primary key. Note that only unique indices with the correct columns are fed to this method. Redefine this method for specific platforms if there are better ways to determine internal indices.

Overrides:

isInternalPrimaryKeyIndex in class JdbcModelReader

Parameters:

metaData - The database meta data

table - The table owning the index

index - The index to check

Returns:

true if the index seems to be an internal primary key one

Throws:

SQLException

isInternalForeignKeyIndex

protected boolean isInternalForeignKeyIndex(DatabaseMetaDataWrapper metaData,
                                Table table,
                                ForeignKey fk,

                                     throws SQLException

Tries to determine whether the index is the internal database-generated index for the given foreign key. Note that only non-unique indices with the correct columns are fed to this method. Redefine this method for specific platforms if there are better ways to determine internal indices.

Overrides:

isInternalForeignKeyIndex in class JdbcModelReader

Parameters:

Overrides:

determineSchemaOf in class JdbcModelReader
