Ryalli's world: COUNT

A. Total Count Check (Completeness)

This query proves you have successfully processed the total number of tables you aimed for.

SELECT

(SELECT COUNT(*) FROM all_tables WHERE owner IN ('HR', 'SALES', 'FINANCE') AND table_name NOT LIKE 'BIN$%') AS source_total_tables,

(SELECT COUNT(*) FROM row_counts_scheduler_log WHERE row_count >= 0) AS logged_successful_tables,

(SELECT COUNT(*) FROM row_counts_scheduler_log WHERE row_count = -1) AS logged_failed_tables,

(SELECT COUNT(*) FROM dba_scheduler_jobs WHERE job_name LIKE 'BATCH_%') AS active_scheduler_jobs

FROM

DUAL;

B. Table Count per Schema (Grouping and Validation)

This query proves your system correctly grouped the tables and is logging the expected counts for each schema. This check directly addresses your requirement to group and compare.

SELECT

t.owner AS schema_name,

COUNT(t.table_name) AS source_table_count,

COUNT(l.table_name) AS logged_table_count,

SUM(CASE WHEN l.row_count = -1 THEN 1 ELSE 0 END) AS failed_count

FROM

all_tables t

LEFT JOIN

row_counts_scheduler_log l ON t.owner = l.schema_name AND t.table_name = l.table_name

WHERE

t.owner IN ('HR', 'SALES', 'FINANCE')

AND t.table_name NOT LIKE 'BIN$%'

GROUP BY

t.owner

ORDER BY

t.owner;

C. Verification of Counts (Smallest Tables for Accuracy)

To prove accuracy, you should compare the actual row counts. Since querying billion-row tables directly is prohibitive, you should check the smallest tables first, as their counts are easy to verify instantly with a direct SELECT COUNT(*).

SELECT
t.owner,
t.table_name,
t.num_rows AS dictionary_estimate,
l.row_count AS logged_live_count,
TO_CHAR(l.count_timestamp, 'HH24:MI:SS') AS log_time
FROM
all_tables t
JOIN
row_counts_scheduler_log l ON t.owner = l.schema_name AND t.table_name = l.table_name
WHERE
t.owner IN ('HR', 'SALES', 'FINANCE')
AND l.row_count >= 0 -- Only check successful entries
ORDER BY
l.row_count ASC -- Order by smallest actual count
FETCH NEXT 20 ROWS ONLY; -- Limit to the 20 smallest tables

The architecture you built provides immediate benefits in terms of reliability and monitoring.

Constraint, Index, and View Advantages

Your setup procedure (reset_row_counts_log) creates three key objects that guarantee the system's integrity and performance:

Object	Definition/Code Used	Advantage & Robustness
Primary Key	`PRIMARY KEY (schema_name, table_name)`	Data Integrity: Guarantees that only one unique, successful log entry exists for any single table. This is the foundation of your system's idempotency (running the job multiple times gives the same result).
Indexes	`idx_batch`(`batch_id`), `idx_row_count`(`row_count`)	Performance: Speeds up your background processes (the auto-restart control loop checks `batch_id` status) and final reports (ordering by `row_count` is instant).
Summary View	`CREATE OR REPLACE VIEW row_count_summary AS...`	Monitoring & Security: Provides a secure, pre-calculated snapshot of job progress, accessible without direct query knowledge.

That's a smart approach. Before pushing a system to production, you need a verifiable demo showing that the results from your asynchronous system (row_counts_scheduler_log) match the source data dictionary (ALL_TABLES).

Here are the queries and explanations to prove the accuracy and robust design of your row counting system.

1. Test Queries to Prove Results

These queries demonstrate that the new log table is accurate, complete, and properly matches the source dictionary.

A. Total Count Check (Completeness)

This query proves you have successfully processed the total number of tables you aimed for.

SQL

SELECT
    (SELECT COUNT(*) FROM all_tables WHERE owner IN ('HR', 'SALES', 'FINANCE') AND table_name NOT LIKE 'BIN$%') AS source_total_tables,
    (SELECT COUNT(*) FROM row_counts_scheduler_log WHERE row_count >= 0) AS logged_successful_tables,
    (SELECT COUNT(*) FROM row_counts_scheduler_log WHERE row_count = -1) AS logged_failed_tables,
    (SELECT COUNT(*) FROM dba_scheduler_jobs WHERE job_name LIKE 'BATCH_%') AS active_scheduler_jobs
FROM
    DUAL;

Proof Point: The value in LOGGED_SUCCESSFUL_TABLES should ideally match SOURCE_TOTAL_TABLES, and ACTIVE_SCHEDULER_JOBS should be 0 (or very low), indicating the workload is complete.

B. Table Count per Schema (Grouping and Validation)

This query proves your system correctly grouped the tables and is logging the expected counts for each schema. This check directly addresses your requirement to group and compare.

SQL

SELECT
    t.owner AS schema_name,
    COUNT(t.table_name) AS source_table_count,
    COUNT(l.table_name) AS logged_table_count,
    SUM(CASE WHEN l.row_count = -1 THEN 1 ELSE 0 END) AS failed_count
FROM
    all_tables t
LEFT JOIN
    row_counts_scheduler_log l ON t.owner = l.schema_name AND t.table_name = l.table_name
WHERE
    t.owner IN ('HR', 'SALES', 'FINANCE')
    AND t.table_name NOT LIKE 'BIN$%'
GROUP BY
    t.owner
ORDER BY
    t.owner;

Proof Point: SOURCE_TABLE_COUNT should equal LOGGED_TABLE_COUNT for every schema (assuming a full successful run).

C. Verification of Counts (Smallest Tables for Accuracy)

SQL

SELECT
    t.owner,
    t.table_name,
    t.num_rows AS dictionary_estimate,
    l.row_count AS logged_live_count,
    TO_CHAR(l.count_timestamp, 'HH24:MI:SS') AS log_time
FROM
    all_tables t
JOIN
    row_counts_scheduler_log l ON t.owner = l.schema_name AND t.table_name = l.table_name
WHERE
    t.owner IN ('HR', 'SALES', 'FINANCE')
    AND l.row_count >= 0 -- Only check successful entries
ORDER BY
    l.row_count ASC -- Order by smallest actual count
FETCH NEXT 20 ROWS ONLY; -- Limit to the 20 smallest tables

Proof Point: For the smallest tables, you can quickly run SELECT COUNT(*) FROM SCHEMA.TABLE and confirm it matches LOGGED_LIVE_COUNT. The DICTIONARY_ESTIMATE is also useful to show that the simple ALL_TABLESmethod is unreliable if statistics are stale.

2. Robustness and Monitoring Advantages

The architecture you built provides immediate benefits in terms of reliability and monitoring.

Constraint, Index, and View Advantages

Your setup procedure (reset_row_counts_log) creates three key objects that guarantee the system's integrity and performance:

Object	Definition/Code Used	Advantage & Robustness
Primary Key	`PRIMARY KEY (schema_name, table_name)`	Data Integrity: Guarantees that only one unique, successful log entry exists for any single table. This is the foundation of your system's idempotency (running the job multiple times gives the same result).
Indexes	`idx_batch`(`batch_id`), `idx_row_count`(`row_count`)	Performance: Speeds up your background processes (the auto-restart control loop checks `batch_id` status) and final reports (ordering by `row_count` is instant).
Summary View	`CREATE OR REPLACE VIEW row_count_summary AS...`	Monitoring & Security: Provides a secure, pre-calculated snapshot of job progress, accessible without direct query knowledge.

View Access and Performance

The row_count_summary view offers significant advantages over querying the raw table or ALL_TABLES:

View vs. Raw Table Query Slowness (Pre-Validation):
- ALL_TABLES Slowness: When querying row counts, the default quick check is SELECT num_rows FROM all_tables. If the statistics are stale, this count is wrong. To get a live count, you must run SELECT COUNT(*), which is extremely slow and resource-heavy (takes hours).
- View Advantage: The row_count_summary view gives instantaneous status (total processed, percentage complete) by querying the pre-logged metadata table. It doesn't need to touch the source tables, meaning zero impact on the high-demand production database.
View Access for Business Users (Monitoring):
- You can grant SELECT access to the row_count_summary view to non-DBA users (e.g., Application Monitoring or Business Intelligence teams).
- This allows them to monitor the progress in real-time without needing complex SQL or permissions on the raw v$session or dba_scheduler_jobs views. They see a simple, clean summary: TOTAL, SUCCESS, FAILED, and PCT_SUCCESS.

COUNT

A. Total Count Check (Completeness)

B. Table Count per Schema (Grouping and Validation)

C. Verification of Counts (Smallest Tables for Accuracy)

Constraint, Index, and View Advantages

1. Test Queries to Prove Results

A. Total Count Check (Completeness)

B. Table Count per Schema (Grouping and Validation)

C. Verification of Counts (Smallest Tables for Accuracy)

2. Robustness and Monitoring Advantages

Constraint, Index, and View Advantages

View Access and Performance

PROOF: WHY ZERO DUPLICATES FOREVER

INSTANT CONFIRMATION QUERY

DOUBLE CONFIRMATION

MY GUARANTEE

RUN CONFIRMATION NOW (5 SECONDS)

IF ANY DOUBT - THIS PROVES IT

Required Change: Update the `count_table_batch` Procedure
