### Question:
StandardGenDialect implements GenDialect { public ColumnType getColumnType(String typeName, int sqlType) { ColumnType columnType = columnTypeMap.get(typeName); return columnType != null ? columnType : fallbackColumnTypeMap .get(sqlType); } StandardGenDialect(); String getName(); String getDefaultSchemaName(String userName); SqlType getSqlType(int sqlType); SqlType getSqlType(ValueTypeProvider valueTypeProvider,
            PropertyMeta propertyMeta); ColumnType getColumnType(String typeName, int sqlType); GenerationType getDefaultGenerationType(); String getOpenQuote(); String getCloseQuote(); String quote(String value); String unquote(String value); boolean supportsSequence(); boolean supportsGetIndexInfo(String catalogName, String schemaName,
            String tableName); String getSequenceDefinitionFragment(String dataType,
            long initialValue, int allocationSize); String getSqlBlockDelimiter(); String getIdentityColumnDefinition(); String getDropForeignKeySyntax(); String getDropUniqueKeySyntax(); boolean isTableNotFound(Throwable throwable); boolean isColumnNotFound(Throwable throwable); boolean isSequenceNotFound(Throwable throwable); SqlBlockContext createSqlBlockContext(); boolean supportsIdentityInsert(); boolean supportsIdentityInsertControlStatement(); String getIdentityInsertEnableStatement(String tableName); String getIdentityInsertDisableStatement(String tableName); boolean supportsNullableUnique(); boolean supportsIdentity(); String getSequenceNextValString(final String sequenceName,
            final int allocationSize); boolean supportsCommentInCreateTable(); boolean supportsCommentOn(); boolean isJdbcCommentAvailable(); String getTableComment(Connection connection, String catalogName,
            String schemaName, String tableName); Map<String, String> getColumnCommentMap(Connection connection,
            String catalogName, String schemaName, String tableName); boolean supportsReferentialDeleteRule(); boolean supportsReferentialUpdateRule(); boolean isAutoIncrement(Connection connection, String catalogName,
            String schemaName, String tableName, String columnName);  }### Answer:
