Advanced SQL++ Queries - Couchbase Query Analyzer v3.16.3

Use these SQL++ examples to extract targeted results from system:completed_requests — by node, by date range, and by excluding system-generated statements — so you can focus on the most relevant queries during analysis.

Common Filters

Remove system-level queries

SELECT
    *, 
    meta().plan
FROM 
    system:completed_requests 
WHERE  
    clientContextID NOT LIKE 'INTERNAL-%' AND 
    UPPER(IFMISSING(preparedText, statement)) NOT LIKE 'INFER %' AND 
    UPPER(IFMISSING(preparedText, statement)) NOT LIKE 'ADVISE %' AND 
    UPPER(IFMISSING(preparedText, statement)) NOT LIKE 'CREATE %' AND 
    UPPER(IFMISSING(preparedText, statement)) NOT LIKE 'CREATE INDEX%' AND 
    UPPER(IFMISSING(preparedText, statement)) NOT LIKE 'ALTER INDEX%' AND 
    UPPER(IFMISSING(preparedText, statement)) NOT LIKE '% SYSTEM:%' 
LIMIT 
    2000;

Search within SQL strings

SELECT
    *, 
    meta().plan
FROM 
    system:completed_requests 
WHERE  
    CONTAINS(`statement`,"SELECT *")
    OR
    CONTAINS(preparedText,"SELECT *")
ORDER BY 
    requestId
LIMIT
    2000;

Between two dates

SELECT
    *, 
    meta().plan
FROM 
    system:completed_requests 
WHERE  
    requestTime BETWEEN "2025-06-01" AND "2025-08-02";

By Node

Current query node

SELECT 
    *,
    meta().plan
FROM
    system:completed_requests
WHERE
    node = NODE_NAME()
LIMIT 
    2000;

Specific query node

SELECT 
    *, 
    meta().plan
FROM 
    system:completed_requests 
WHERE 
    node LIKE "10.132.133.165%" 
LIMIT
    2000;
