Write SQL queries for Celigo RDBMS exports and imports -- SELECT, INSERT, UPDATE, UPSERT, MERGE, delta, once, and bulk operations across Snowflake, Postgres, MySQL, SQL Server, Oracle, BigQuery, and Redshift. Use when editing rdbms.query or troubleshooting SQL errors.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- TIER:1 -->
# Writing SQL for RDBMS Integrations
RDBMS exports and imports use SQL queries to read from and write to relational databases. Queries are Handlebars templates -- the platform evaluates expressions like `{{{record.fieldName}}}` at runtime, then executes the resulting SQL against the connected database.
This skill covers **what SQL to write and how to write it**. For which adaptor type to use, connection setup, and queryType selection, see the related skills below.
## Quick Reference
### Context decision matrix
| Where | Field | Handlebars prefix | Braces | Example |
|---|---|---|---|---|
| Export query | `rdbms.query` | `record.` (parameterized) or none (standalone) | `{{{ }}}` | `SELECT * FROM orders WHERE id = {{{record.id}}}` |
| Export delta query | `rdbms.query` | platform-injected tokens | `{{ }}` (adds the quotes) | `WHERE updated_at > {{lastExportDateTime}}` |
| Export once mark-as-processed | `rdbms.once.query` | `record.` | `{{{ }}}` | `UPDATE orders SET exported = true WHERE id = {{{record.id}}}` |

How to install
mdr add celigo/ai/writing-sql@sha256:caca1468ed09f122The line at the top of this page pins the label git:20261017.e0e159f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
