Inspect upstream and downstream dependencies for any model, source, seed, or function in your project. Supports both model-level lineage (dependency graph) and column-level lineage (tracing individual columns through transformations). Outputs as a tree, edge list, or structured JSON.

​
Usage

# Model lineage: dependency graph around a single resource
sqb lineage <target> [flags]

# Column lineage: trace a specific column
sqb lineage <model>.<column> [flags]

# Selector mode: lineage for a selected scope
sqb lineage --select <selector> [flags]
Exactly one of a positional target or --select is required.

​
Flags

FlagDescription
--directionupstream (default), downstream, or both. both is only available for model lineage.
--depthHow many hops to traverse. An integer or all (default: all).
--formatOutput format: tree (default), list, or json.
--modeColumn lineage analysis mode: rich (default) or fast.
--no-sql-validationSkip compile-time SQL syntax validation.
--select, -sSelect resources using standard selector syntax.
--excludeExclude resources from the selection.

​
Model lineage

When the target is a plain resource name, lineage shows the model-level dependency graph.

​
Tree

The default. Shows an indented dependency tree with resource types and file paths: 
sqb lineage fact_orders --direction both

Cycles and repeated nodes are annotated with “(already shown)” to avoid infinite recursion.

​
List

An edge list showing each dependency as a directed pair: 
sqb lineage fact_orders --format list

source:raw__orders    -> model:stg_orders
source:raw__payments  -> model:stg_payments
model:stg_orders     -> model:fact_orders
model:stg_payments   -> model:fact_orders
seed:waffle_types    -> model:fact_orders

​
JSON

Structured output with nodes, edges, and metadata: 
sqb lineage fact_orders --format json

{
  "nodes": [
    {
      "id": "model:fact_orders",
      "name": "fact_orders",
      "resource_type": "model",
      "relative_path": "models/marts/fact_orders.sql",
      "qualified_name": "dev.fact_orders"
    },
    {
      "id": "source:raw__orders",
      "name": "raw__orders",
      "resource_type": "source",
      "relative_path": "sources/raw.yml"
    }
  ],
  "edges": [
    {"from": "source:raw__orders", "to": "model:stg_orders"},
    {"from": "model:stg_orders", "to": "model:fact_orders"}
  ],
  "focus": ["model:fact_orders"],
  "direction": "upstream"
}

​
Column lineage

When the target uses model.column syntax, lineage traces the specific column through upstream or downstream transformations. Each edge is annotated with a transform type (direct, expression, aggregation, cast, star, constant) and a confidence level. See Column Lineage for a full explanation of transform types, confidence levels, and analysis modes. 
# Where does fact_orders.total_cents come from?
sqb lineage fact_orders.total_cents

# What consumes fact_orders.order_id downstream?
sqb lineage fact_orders.order_id --direction downstream
Column lineage supports upstream and downstream directions (not both). The --mode flag selects the analysis mode: rich (default, full SQL analysis) or fast (lightweight, faster on large projects).

​
Tree

Examples

# Upstream dependencies of a model (default)
sqb lineage fact_orders

# Downstream dependents
sqb lineage fact_orders --direction downstream

# Both directions, limited to 1 hop
sqb lineage fact_orders --direction both --depth 1

# Column lineage: trace a specific column upstream
sqb lineage fact_orders.total_cents

# Column lineage: trace downstream consumers
sqb lineage fact_orders.order_id --direction downstream

# Column lineage with depth limit
sqb lineage fact_orders.total_cents --depth 1

# Lineage for all models in a path
sqb lineage --select path:marts

# Lineage between two models (path-between)
sqb lineage --select "stg_orders~daily_activity_rollup"

# Upstream expansion from a model
sqb lineage --select "+fact_orders"

# JSON output for programmatic consumption
sqb lineage fact_orders --format json --direction upstream

​
Depth limiting

--depth controls how many hops from the focus node(s) to include. In selector mode, --depth requires name, source, seed, or path-between selectors - it cannot be combined with tag or path selectors or comma-intersection selectors. 
# Only immediate parents
sqb lineage fact_orders --depth 1

# Parents and grandparents
sqb lineage fact_orders --depth 2

# Only direct column dependencies
sqb lineage fact_orders.total_cents --depth 1
