## About

> **Update Check — ONCE PER SESSION (mandatory)**
> The first time this skill is used in a session, run the **check-updates** skill before proceeding.
> - **GitHub Copilot CLI / VS Code**: invoke the `check-updates` skill.
> - **Claude Code / Cowork / Cursor / Windsurf / Codex**: compare local vs remote package.json version.
> - Skip if the check was already performed earlier in this session.

> **CRITICAL NOTES**
> 1. To find the workspace details (including its ID) from workspace name: list all workspaces and, then, use JMESPath filtering
> 2. To find the item details (including its ID) from workspace ID, item type, and item name: list all items of that type in that workspace and, then, use JMESPath filtering

## Tool Stack

| Tool | Role | Install |
|---|---|---|
| `sqlcmd` (Go) | **Primary**: Execute T-SQL. Standalone binary, no ODBC driver, built-in Entra ID auth via `DefaultAzureCredential`. | `winget install sqlcmd` / `brew install sqlcmd` / `apt-get install sqlcmd` |
| `az` CLI | Auth (`az login`), token acquisition, Fabric REST for endpoint discovery. | Pre-installed in most dev environments |
| `jq` | Parse JSON from `az rest` | Pre-installed or trivial |

> **Agent check** — verify before first SQL operation:
> ```bash
> sqlcmd --version 2>/dev/null || echo "INSTALL: winget install sqlcmd OR brew install sqlcmd"
> ```

## Connection

### Discover the SQL Endpoint FQDN

Per [COMMON-CLI.md](../../common/COMMON-CLI.md) Discovering Connection Parameters via REST:

```bash
WS_ID=""
ITEM_ID=""

# Warehouse
az rest --method get \
  --resource "https://api.fabric.microsoft.com" \
  --url "https://api.fabric.microsoft.com/v1/workspaces/$WS_ID/warehouses/$ITEM_ID" \
  --query "properties.connectionString" --output tsv

# Lakehouse SQL endpoint
az rest --method get \
  --resource "https://api.fabric.microsoft.com" \
  --url "https://api.fabric.microsoft.com/v1/workspaces/$WS_ID/lakehouses/$ITEM_ID" \
  --query "properties.sqlEndpointProperties.connectionString" --output tsv
```

Result: `.datawarehouse.fabric.microsoft.com`

### Connect with sqlcmd (Go)

```bash
# Interactive session (Entra login via browser if needed)
sqlcmd -S ".datawarehouse.fabric.microsoft.com" -d "" -G

# Non-interactive one-shot query
sqlcmd -S ".datawarehouse.fabric.microsoft.com" -d "" -G \
  -Q "SELECT TOP 10 * FROM dbo.FactSales"

# Explicit ActiveDirectoryDefault (uses az login session)
sqlcmd -S ".datawarehouse.fabric.microsoft.com" -d "" \
  --authentication-method ActiveDirectoryDefault \
  -Q "SELECT TOP 10 * FROM dbo.FactSales"

# Service principal (CI/CD)
SQLCMDPASSWORD="" \
sqlcmd -S ".datawarehouse.fabric.microsoft.com" -d "" \
  --authentication-method ActiveDirectoryServicePrincipal \
  -U "" \
  -Q "SELECT COUNT(*) FROM dbo.FactSales"
```

### Reusable Connection Variables

```bash
# Set once at script top
FABRIC_SERVER=".datawarehouse.fabric.microsoft.com"
FABRIC_DB=""
SQLCMD="sqlcmd -S $FABRIC_SERVER -d $FABRIC_DB -G"

# Use throughout
$SQLCMD -Q "SELECT TOP 5 * FROM dbo.DimProduct"
$SQLCMD -i myscript.sql
```

### PowerShell / Windows CMD

```powershell
# PowerShell
$s = ".datawarehouse.fabric.microsoft.com"; $db = ""
sqlcmd -S $s -d $db -G -Q "SELECT TOP 10 * FROM dbo.FactSales"
# CMD: use set S=... and %S% / %DB% instead of $variables
```

## Agentic Exploration ("Chat With My Data")

### Schema Discovery Sequence

Run these in order to understand what's in the endpoint. See [references/discovery-queries.md](references/discovery-queries.md) for extended discovery queries.

```bash
# 1. List schemas
$SQLCMD -Q "SELECT schema_name FROM information_schema.schemata ORDER BY schema_name" -W

# 2. List tables and views
$SQLCMD -Q "SELECT table_schema, table_name, table_type FROM information_schema.tables ORDER BY table_schema, table_name" -W

# 3. Columns for a table
$SQLCMD -Q "SELECT column_name, data_type, character_maximum_length, is_nullable FROM information_schema.columns WHERE table_schema='dbo' AND table_name='FactSales' ORDER BY ordinal_position" -W

# 4. Preview rows
$SQLCMD -Q "SELECT TOP 5 * FROM dbo.FactSales" -W

# 5. Row counts
$SQLCMD -Q "SELECT s.name AS [schema], t.name AS [table], SUM(p.rows) AS row_count FROM sys.tables t JOIN sys.schemas s ON t.schema_id=s.schema_id JOIN sys.partitions p ON t.object_id=p.object_id AND p.index_id IN (0,1) GROUP BY s.name, t.name ORDER BY row_count DESC" -W

# 6. Programmability objects (views, functions, procedures)
$SQLCMD -Q "SELECT name, type_desc FROM sys.objects WHERE type IN ('V','FN','IF','P','TF') ORDER BY type_desc, name" -W
```

### Agentic Workflow

1. **Discover** → Run Steps 1–3 to understand available tables/columns.
2. **Sample** → `SELECT TOP 5` on relevant tables.
3. **Formulate** → Write T-SQL using [SQLDW-CONSUMPTION-CORE.md](../../common/SQLDW-CONSUMPTION-CORE.md) Supported T-SQL Surface Area.
4. **Execute** → `$SQLCMD -Q "..."`.
5. **Iterate** → Refine based on results.
6. **Present** → Show results or generate a reusable script (Script Generation section).

## Gotchas, Rules, Troubleshooting

For full T-SQL/platform gotchas: [SQLDW-CONSUMPTION-CORE.md](../../common/SQLDW-CONSUMPTION-CORE.md) Gotchas and Troubleshooting Reference and [COMMON-CLI.md](../../common/COMMON-CLI.md) Gotchas & Troubleshooting (CLI-Specific).

### MUST DO

- **Always `-d `** — FQDN alone is insufficient.
- **Always `-G` or `--authentication-method`** — SQL auth not supported on Fabric.
- **`az login` first** — `ActiveDirectoryDefault` uses az session. No session → cryptic failure.
- **`SET NOCOUNT ON;`** in scripts — suppresses row-count messages that corrupt output.
- **Label queries** with `OPTION (LABEL = 'AGENTCLI_...')` for Query Insights tracing.

### AVOID

- **ODBC sqlcmd** (`/opt/mssql-tools/bin/sqlcmd`) — requires ODBC driver. Use Go version.
- **Omitting `-W`** in scripts — trailing spaces corrupt CSV.
- **DML on SQLEP** — Lakehouse/Mirrored DB endpoints are read-only. DML only on Warehouse.
- **MARS** — not supported. Remove `MultipleActiveResultSets` from connection strings.
- **Hardcoded FQDNs** — discover via REST API (Discover the SQL Endpoint FQDN).

### PREFER

- **`sqlcmd (Go) -G`** over curl+token for SQL queries.
- **`-Q`** (non-interactive exit) for agentic use.
- **Piped input** for multi-statement batches or queries with quotes.
- **`-i file.sql`** for complex queries — avoids shell escaping.
- **`-F vertical`** for exploration of wide tables.
- **Env vars** (`FABRIC_SERVER`, `FABRIC_DB`) for script reuse.
- **`az rest`** for Fabric REST API — use sqlcmd only for T-SQL.

### TROUBLESHOOTING

| Symptom | Cause | Fix |
|---|---|---|
| `Login failed for user ''` | Wrong DB name or no access | Verify `-d` matches item name exactly (case-sensitive) |
| `Cannot open server` | Wrong FQDN or network | Re-discover via REST API; check port 1433 |
| `Login timeout expired` | Port 1433 blocked | `nc -zv  1433`; check firewall/VPN |
| `ActiveDirectoryDefault` failure | `az login` expired or wrong tenant | `az login --tenant ` |
| Garbled CSV output | Missing `-W` or wrong `-s` | Add `-W -s"," -w 4000` |
| `(N rows affected)` in file | No `SET NOCOUNT ON` | Prepend `SET NOCOUNT ON;` |
| `Invalid object name 'queryinsights...'` | New warehouse < 2 min old | Wait ~2 minutes |
| No rows but data exists | RLS filtering | Check `USE
