How to Understand Missing Tables in Table Explorer

Issue

A table is not visible in the Table Explorer, despite the table being present in the database.

Environment

HVR 6

Resolution

This article demonstrates two scenarios.

Table Explorer does not list a1_tpcc because it is owned by the tpcc schema and the hvrhub4 schema does not have select privilege on it.
Table Explorer does not list a1_temp because it is a global temporary table. HVR does not support global temporary tables because they are not static.

In the following examples:

Oracle is the source database
The schema hvrhub4 is the hub schema
a1_temp is a global temporary table present in the hvrhub4 schema
a1_tpcc table is owned by the tpcc schema

Scenario 1

HVR user hvrhub4 does not have the privilege to select the table a1_tpcc.

Solution: Grant hvrhub4 privilege to select the table a1_tpcc.

Scenario 2:

The table a1_temp is a global temporary table. If the table is visible in the database schema but it is not visible while adding to the replication, it is possible that this table is a temporary table.

HVR does not support global temporary tables because they are not static.

Run the below query to get the DDL of the table a1_temp. The DDL of the table tells if it is a temporary table.

SQL> spool ddl_list.sql;
SQL> SET HEADING OFF;
SQL> SET ECHO OFF;
SQL> SET PAGES 999;
SQL> SET LONG 90000;
SQL> SPOOL DDL_LIST.SQL ;
SQL> SELECT DBMS_METADATA.GET_DDL('TABLE','A1_TEMP','HVRHUB4') FROM DUAL;

Result of the query:

CREATE GLOBAL TEMPORARY TABLE "HVRHUB4"."A1_TEMP"   
( "C1" NUMBER(*,0),     
"C2" VARCHAR2(25 BYTE)   
) ON COMMIT DELETE ROWS ;
