// SEQUENTIAL SCAN · orders

Full scan of orders: 42,118 rows read, 31,880 discarded by the status filter. Mongrel suggests a composite index on (status, order_date) to kill both the scan and the sort.

-- stores_demo@ol_informix · orders
SELECT FIRST 20
  o.order_num, o.order_date, o.status,
  c.company AS customer_name
FROM orders o
JOIN customer c ON c.customer_num = o.customer_num
WHERE o.status = 'O'
  AND o.order_date >= '2026-06-01'
ORDER BY o.order_date DESC;

-- 1.9s · 42,118 rows scanned · sort 84% of cost
-- Proposal: composite (status, order_date) on orders

CREATE INDEX ix_status_order_date

Informix surface

What Mongrel ships for Informix.

Database & object browsing

Browse databases, tables, views, synonyms, procedures, and triggers from sysmaster and syscat — no dbaccess required.

SQL editor & grid

Write and run SQL with syntax-aware editing. Results land in an editable grid, from plain SELECTs to FIRST n queries.

EXPLAIN & plan viewer

Runs SET EXPLAIN under the hood and renders the plan tree: QUERY, SORT, HASH JOIN, INDEX PATH, SEQUENTIAL SCAN — with cost and row estimates per node.

Row & bulk CRUD

Edit rows in place, or stage bulk INSERT, UPDATE, and DELETE batches. Preview affected row counts before committing.

Transactions & savepoints

Start a transaction, set savepoints, roll back to one, commit when satisfied — against logged databases, with isolation level selection.

Table & index inspection

Columns, types, constraints, fragments, and index paths in one panel. See which indexes the optimizer actually uses.

Import & export

CSV, JSON, and delimited unload/load in and out of any table. Copy data between Informix and other engines, schema-aware.

clidriver under the hood

Mongrel talks DRDA through a user-installed IBM clidriver. Point it at your existing install — no server-side agents or proxies.

TLS connections

Encrypted DRDA sessions over TLS with certificate verification. Save multiple connection profiles per host and database.
