Examples

History Queries

# Recent prompts
ccql "SELECT display FROM history ORDER BY timestamp DESC LIMIT 10"

# Search prompts
ccql "SELECT display FROM history WHERE display LIKE '%error%'"

# Prompts by project
ccql "SELECT project, COUNT(*) as n FROM history GROUP BY project ORDER BY n DESC"

# Long prompts (likely pasted code)
ccql "SELECT LENGTH(display) as len, SUBSTR(display, 1, 60) as preview
      FROM history ORDER BY len DESC LIMIT 10"

Transcript Queries

# Tool usage stats
ccql "SELECT tool_name, COUNT(*) as n FROM transcripts
      WHERE type='tool_use' GROUP BY tool_name ORDER BY n DESC"

# Most active sessions
ccql "SELECT _session_id, COUNT(*) as n FROM transcripts
      GROUP BY _session_id ORDER BY n DESC LIMIT 10"

# Find sessions mentioning a topic
ccql "SELECT DISTINCT _session_id FROM transcripts
      WHERE content LIKE '%authentication%'"

Todo Queries

# Pending todos
ccql "SELECT content FROM todos WHERE status='pending'"

# Todo counts by status
ccql "SELECT status, COUNT(*) as n FROM todos GROUP BY status"

Output Formats

ccql -f table "SELECT ..."    # Pretty table (default)
ccql -f json "SELECT ..."     # JSON array
ccql -f jsonl "SELECT ..."    # JSON lines
ccql -f raw "SELECT ..."      # Raw output

Write Operations

Write operations require explicit flags for safety:

# Preview changes (dry run)
ccql --dry-run "DELETE FROM history WHERE timestamp < 1700000000000"

# Execute with backup
ccql --write "DELETE FROM history WHERE timestamp < 1700000000000"

Other Commands

ccql prompts                  # Extract prompts with filtering
ccql sessions                 # List sessions
ccql search "term"            # Full-text search
ccql todos --status pending   # List todos
ccql stats                    # Usage statistics
ccql duplicates               # Find repeated prompts
ccql query '.[]' history      # jq-style queries

Configuration

# Set data directory
export CLAUDE_DATA_DIR=~/.claude

# Or via flag
ccql --data-dir ~/.claude "SELECT ..."
