### End-to-End Tabular Connector Example

Source: https://github.com/microsoft/power-fx/blob/main/docs/Microsoft.PowerFx.Connectors-explained.md

This C# code demonstrates building an HTTP transport, initializing a Power Platform connector client, fetching dataset metadata, querying a specific table, and evaluating a Power Fx formula against the data. It shows the complete workflow from client setup to formula execution.

```csharp
using System;
using System.Linq;
using System.Net.Http;
using System.Threading;
using System.Threading.Tasks;
using Microsoft.PowerFx;
using Microsoft.PowerFx.Connectors;
using Microsoft.PowerFx.Types;

public static class TabularConnectorSample
{
    public static async Task RunAsync()
    {
        // 1. Build the HTTP transport. PowerPlatformConnectorClient handles
        //    the APIM /invoke wire protocol used by Power Platform connectors.
        using var httpClient = new HttpClient();
        using var client = new PowerPlatformConnectorClient(
            endpoint:      "firstrelease-003.azure-apihub.net",
            environmentId: "49970107-0806-e5a7-be5e-7c60e2750f01",
            connectionId:  "18992e9477684930acd2cc5dc9bb94c2",
            getAuthToken:  () => "<JWT>",
            httpInvoker:   httpClient)
        { SessionId = Guid.NewGuid().ToString() };

        var logger      = new ConsoleLogger();
        var basePath    = $"/apim/sql/{client.ConnectionId}";
        var datasetName = "pfxdev-sql.database.windows.net,connectortest";

        // 2. Fetch dataset metadata + table list.  (HTTP #1 and #2)
        var cds    = new CdpDataSource(datasetName, ConnectorSettings.NewCDPConnectorSettings());
        var tables = await cds.GetTablesAsync(client, basePath, CancellationToken.None, logger);

        // 3. Pick the table we care about and fetch its schema.  (HTTP #3)
        CdpTable customers = tables.First(t => t.DisplayName == "Customers");
        await customers.InitAsync(client, basePath, CancellationToken.None, logger);

        // 4. Wrap it as a Power Fx TableValue and register it in a SymbolTable.
        CdpTableValue customersValue = customers.GetTableValue();
        var symbolValues = new SymbolValues().Add("Customers", customersValue);

        // 5. Bind & evaluate.  The engine will delegate the Filter/Sort/First back
        //    to CdpTable.Query via CdpTableValue.GetRowsAsync.  (HTTP #4)
        var config = new PowerFxConfig(Features.PowerFxV1);
        var engine = new RecalcEngine(config);
        var rc     = new RuntimeConfig(symbolValues).AddService<ConnectorLogger>(logger);

        FormulaValue result = await engine.EvalAsync(
            @"First(Filter(Customers, Country = ""France"")).Address",
            CancellationToken.None,
            options:      new ParserOptions { AllowsSideEffects = true },
            runtimeConfig: rc);

        Console.WriteLine(((StringValue)result).Value);

Initializes a table named 't1' with two records. This setup is used in subsequent examples to demonstrate mutation.

```PowerFx
Set( t1, [1,2] )
Table({Value:1},{Value:2})
```

### Match Function with Valid Quantifiers and Capture Groups

Source: https://github.com/microsoft/power-fx/blob/main/src/tests/Microsoft.PowerFx.Core.Tests.Shared/ExpressionTestCases/MatchFunctions_CaptureQuant.txt

These examples show successful matches using the 'Match' function with various quantifiers and capture groups. The output includes the full match, start position, and submatches.

```PowerFx
Match( "%aaa%", "(a+)?", MatchOptions.NumberedSubMatches )
{FullMatch:"aaa",StartMatch:2,SubMatches:Table({Value:"aaa"})}
```

```PowerFx
Match( "%aaa%", "(a{1})?", MatchOptions.NumberedSubMatches )
{FullMatch:"",StartMatch:1,SubMatches:Table({Value:Blank()})}
```

```PowerFx
Match( "%aaa%", "(a{1,})?", MatchOptions.NumberedSubMatches )
{FullMatch:"",StartMatch:1,SubMatches:Table({Value:Blank()})}
```

```PowerFx
Match( "%aaa%", "(a{1,2})?", MatchOptions.NumberedSubMatches )
{FullMatch:"",StartMatch:1,SubMatches:Table({Value:Blank()})}
```

```PowerFx
Match( "%aaa%", "(a+){1}", MatchOptions.NumberedSubMatches )
{FullMatch:"aaa",StartMatch:2,SubMatches:Table({Value:"aaa"})}
```

```PowerFx
Match( "%aaa%", "(a{1}){1}", MatchOptions.NumberedSubMatches )
{FullMatch:"a",StartMatch:2,SubMatches:Table({Value:"a"})}
```

```PowerFx
Match( "%aaa%", "(a{1,}){1}", MatchOptions.NumberedSubMatches )
{FullMatch:"aaa",StartMatch:2,SubMatches:Table({Value:"aaa"})}
```

```PowerFx
Match( "%aaa%", "(a{1,2}){1}", MatchOptions.NumberedSubMatches )
{FullMatch:"aa",StartMatch:2,SubMatches:Table({Value:"aa"})}
```

--------------------------------

### Start Match Index with Complete Option

Source: https://github.com/microsoft/power-fx/blob/main/src/tests/Microsoft.PowerFx.Core.Tests.Shared/ExpressionTestCases/Match.txt

Retrieves the starting index when using MatchOptions.Complete, which returns Blank() if the entire string does not match.

```PowerFx
>> Match("Hello", "llo", MatchOptions.Complete).StartMatch
Blank()
```

### Getting Length of GUID

Source: https://github.com/microsoft/power-fx/blob/main/src/tests/Microsoft.PowerFx.Core.Tests.Shared/ExpressionTestCases/ArgCoercion_V1Compat.txt

Illustrates the use of the Len function with GUID() to determine the standard length of a generated GUID, which is 36 characters.

```PowerFx
Len(GUID())
```

### GUID and String Coercion

Source: https://github.com/microsoft/power-fx/blob/main/src/tests/Microsoft.PowerFx.Interpreter.Tests.Shared/InterpreterExpressionTestCases/BasicCoercion_V1CompatDisabled_Overrides.txt

Demonstrates the behavior of coercing a GUID to a string when V1 compatibility is disabled. This example is skipped as it represents a bug fixed in V1.

```PowerFx

### Record Initialization and Comparison

Source: https://github.com/microsoft/power-fx/blob/main/src/tests/Microsoft.PowerFx.Interpreter.Tests.Shared/MutationScripts/AutomatedLowCodePlugins.txt

Demonstrates the creation of records with different data types and the comparison of individual fields. Direct record comparison is not supported and results in a type error.

```Power Fx
NewRecord
{Field1:1,Field2:"earth",Field3:DateTime(2022,1,1,0,0,0,0),Field4:true}
```

```Power Fx
OldRecord
{Field1:2,Field2:"moon",Field3:DateTime(2022,2,1,0,0,0,0),Field4:false}
```

```Power Fx

{Field1:1,Field2:"earth",Field3:DateTime(2022,1,1,0,0,0,0),Field4:true}
```

```Power Fx
NewRecord.Field1 = OldRecord.Field1
```

```Power Fx
NewRecord.Field4 = Not( OldRecord.Field4 )
```

```Power Fx
Boolean(NewRecord = OldRecord)
```
