OQL Syntax Reference

Complete syntax reference for OneTest Query Language (OQL).

Query Structure

<filter_expression> [ORDER BY <field> [ASC|DESC]] [LIMIT <n>] [OFFSET <n>]

All parts except the filter expression are optional.

Operators

Comparison Operators

Operator	Description	Example
`=`	Equals	`status = active`
`!=`	Not equals	`priority != p4`
`>`	Greater than	`version > 2.0`
`>=`	Greater or equal	`created_at >= 2024-01-01`
`<`	Less than	`priority < p2`
`<=`	Less or equal	`updated_at <= -7d`
`IS NULL`	Field is null	`last_run IS NULL`
`IS NOT NULL`	Field is not null	`folder_id IS NOT NULL`
`BETWEEN`	Value in range	`created_at BETWEEN 2024-01-01 AND 2024-12-31`

String Pattern Operators

Operator	Description	Example
`~`	Contains (case-insensitive)	`title ~ "login"`
`!~`	Does not contain	`description !~ "deprecated"`
`^`	Starts with	`identifier ^ "TC-10"`
`$`	Ends with	`title $ "test"`

List Operators

Operator	Description	Example
`IN`	Value in list	`priority IN (p1, p2, p3)`
`NOT IN`	Value not in list	`status NOT IN (archived, deleted)`

Array Operators

Operator	Description	Example
`CONTAINS`	Array contains value	`tags CONTAINS "smoke"`
`NOT CONTAINS`	Array does not contain	`tags NOT CONTAINS "deprecated"`
`CONTAINS ANY`	Array contains any value	`tags CONTAINS ANY (smoke, regression)`
`CONTAINS ALL`	Array contains all values	`tags CONTAINS ALL (smoke, critical)`

Logical Operators

Operator	Description	Example
`AND`	Both conditions must be true	`status = active AND priority = p1`
`OR`	Either condition must be true	`priority = p1 OR priority = p2`
`NOT`	Negate condition	`NOT status = archived`
`( )`	Group conditions	`(status = active OR status = approved) AND priority = p1`

Data Types

Strings

Enclose in double or single quotes:

title = "User Login"
title = 'User Login'

Use quotes for strings with spaces or special characters.

Numbers

No quotes needed:

version = 2
priority_number > 1

Booleans

automated = true
is_flaky = false

Dates

ISO Format
Relative Dates
Date Functions

created_at = 2024-01-15
created_at = "2024-01-15T10:30:00Z"

created_at >= -7d        # 7 days ago
created_at >= -2w        # 2 weeks ago
created_at >= -3M        # 3 months ago
created_at >= -1y        # 1 year ago

Units: d (days), w (weeks), M (months), y (years)

created_at >= startOfWeek()
created_at >= startOfMonth()
created_at >= startOfQuarter()
created_at >= startOfYear()
created_at <= endOfWeek()
created_at <= endOfMonth()
created_at <= endOfQuarter()
created_at <= endOfYear()

Null Values

last_run IS NULL
description IS NOT NULL

Field Names

Field names are case-sensitive:

✅ status = active
❌ Status = active
❌ STATUS = active

For fields with spaces or special characters, use quotes:

"custom field" = "value"

Ordering

Single Field
Multiple Fields

ORDER BY created_at DESC
ORDER BY priority ASC
ORDER BY title

Default order is ASC (ascending).

ORDER BY priority ASC, created_at DESC
ORDER BY status, priority, title

Sorts by first field, then second, etc.

Pagination

# First 50 results
LIMIT 50

# Next 50 results
LIMIT 50 OFFSET 50

# Third page (rows 101-150)
LIMIT 50 OFFSET 100

OFFSET requires LIMIT to be specified.

Examples by Complexity

Simple
Moderate
Complex

# Single condition
status = active

# With ordering
status = active ORDER BY created_at DESC

# With limit
priority = p1 LIMIT 10

# AND condition
status = active AND priority IN (p1, p2)

# OR condition
priority = p1 OR tags CONTAINS "critical"

# Pattern matching
title ~ "login" AND status != archived

# Date filtering
created_at >= -30d ORDER BY created_at DESC LIMIT 100

# Multiple conditions with grouping
(status = active OR status = approved) AND
priority IN (p0, p1, p2) AND
tags CONTAINS ANY (smoke, regression) AND
created_at >= -90d
ORDER BY priority ASC, created_at DESC
LIMIT 50

# Array operations
tags CONTAINS ALL (smoke, critical) AND
tags NOT CONTAINS "deprecated" AND
last_run >= -7d

# Null checks and comparisons
last_run IS NOT NULL AND
last_run < updated_at AND
status = active

Operator Precedence

From highest to lowest:

( ) - Parentheses
NOT - Logical NOT
=, !=, >, >=, <, <=, ~, ^, $, IN, CONTAINS - Comparison operators
AND - Logical AND
OR - Logical OR

Use parentheses to make precedence explicit: (A OR B) AND C

Common Patterns

Find by Multiple Tags

# Has all these tags
tags CONTAINS ALL (smoke, critical, login)

# Has any of these tags
tags CONTAINS ANY (smoke, regression)

# Has this tag but not that tag
tags CONTAINS "smoke" AND tags NOT CONTAINS "deprecated"

Date Ranges

# This month
created_at >= startOfMonth()

# Last 7 days
created_at >= -7d

# Specific range
created_at BETWEEN 2024-01-01 AND 2024-12-31

# Before a date
created_at < 2024-06-01

Multiple Priorities

# Any of these priorities
priority IN (p0, p1, p2)

# Higher priority than P2
priority < p2

# Exclude low priorities
priority NOT IN (p3, p4)

Text Search

# Contains word
title ~ "login"

# Starts with
identifier ^ "TC-10"

# Ends with
title $ "test"

# Multiple words (any)
title ~ "login" OR title ~ "authentication"

# Multiple words (all)
title ~ "login" AND description ~ "valid credentials"

Validation Rules

Field names must exist in the schema
Operators must match field types (can’t use ~ on numbers)
Date formats must be valid ISO 8601
Array operators only work on array fields
Priority values must be valid (p0-p4)

Error Messages

Common errors and how to fix them:

Error	Cause	Fix
`Unknown field: xyz`	Field doesn’t exist	Check field reference
`Invalid operator for field type`	Wrong operator for field	Use comparison operators for numbers, pattern operators for strings
`Invalid date format`	Bad date syntax	Use ISO 8601: `2024-01-15` or relative: `-7d`
`Expected AND/OR`	Missing logical operator	Add `AND` or `OR` between conditions
`Unclosed quote`	Missing closing quote	Ensure all strings have matching quotes
