private void
handleEnableAutoIncrementValidationLegacyJdbc(Column column, Database database, String rawCatalogName, String rawSchemaName, String rawTableName, String rawColumnName)

public Map<String, Column.AutoIncrementInformation>

Returns:

Map with the sequence name and auto increment details
obtainSequencesInformation(Database
