Allows platforms to issue statements directly before rows are inserted into the specified table.

Overrides:

beforeInsert in class PlatformImplBase

Parameters:

connection - The connection used for the insertion

table - The table that the rows are inserted into

Throws:

SQLException

afterInsert

protected void afterInsert(Connection connection,
               Table table)
                    throws SQLException

Allows platforms to issue statements directly after rows have been inserted into the specified table.

Overrides:

afterInsert in class PlatformImplBase

Parameters:
