-- Migration Doctor snapshot, SQL export: all saved filters, including other users' private filters, with JQL and owner username.
-- Read-only: a single SELECT, no writes, no temporary tables. Output: one JSON object per line.
-- Run (read-only) with sqlcmd and save the output as filters.jsonl. JIRA_SCHEMA is the schema of the
-- Jira tables (usually jiraschema, sometimes dbo):
--   sqlcmd -S DBHOST -d JIRADB -E -v JIRA_SCHEMA=jiraschema -y 0 -f 65001 -i filters.sql -o export/filters.jsonl
-- (-E uses Windows authentication; use -U READONLY_USER and let sqlcmd prompt for the password otherwise.)
-- Then pass the export directory to the snapshot script: --sql-export-dir export (bash) or -SqlExportDir export (PowerShell).
