ADO.NET query not showing in XEvents


I sent a query to SQL Server using an ADO.Net SqlAdapter from PowerShell. The query returns the correct result. When I run an XEvent session with the sqlserver.sql_statement_starting event, the query from ADO.NET does not show up. Queries I sent from SSMS are shown immediately.

Is this a bug, or why do I not see the ADO.NET queries?

The code I am using is

$serverName = 'localhost'
$databaseName = 'Contoso Retail DW'
$schemaName = 'dbo'
$tableName = 'FactSalesFMCG'

$connString = Get-ConnectionString -IntegratedSecurity -Server $serverName -Database $databaseName 
$sqlConn = [System.Data.SqlClient.SqlConnection]::new($connString) 
$sqlConn.Open()
$columnMetadataAdapter = Get-ColumnMetadataAdapter -Conn $sqlConn -SchemaName $schemaName -TableName $tableName
$table = [System.Data.DataTable]::new()
$columnMetadataAdapter.Fill($table)
$sqlConn.Close()

Get-ConnectionString and Get-ColumnMetadataAdapter are PowerShell functions that assist in creating the needed ADO.NET objects. The table gets filled with the column metadata I wanted, but the SELECT statement is not shown in XEvents.


Solution

  • Can't repro.

    CREATE EVENT SESSION [trc] ON SERVER 
    ADD EVENT sqlserver.rpc_completed,
    ADD EVENT sqlserver.sp_statement_completed,
    ADD EVENT sqlserver.sql_batch_completed,
    ADD EVENT sqlserver.sql_statement_completed
    GO
    

    Start the session and watch live events in SSMS.

    Then

    PS C:\Users\dbrowne> $da = new-object system.data.sqlclient.sqldataadapter
    PS C:\Users\dbrowne> $con = new-object system.data.sqlclient.sqlconnection "server=.;database=tempdb;integrated security=true"
    PS C:\Users\dbrowne> $con.open()
    PS C:\Users\dbrowne> $cmd = $con.createcommand()
    PS C:\Users\dbrowne> $cmd.commandtext = "select * from sys.objects"
    PS C:\Users\dbrowne> $da.selectcommand = $cmd
    PS C:\Users\dbrowne> $dt = new-object system.data.datatable
    PS C:\Users\dbrowne> $da.fill($dt)
    106
    

    and see both the sql_statement_completed and the sql_batch_completed (note with different code you might get an rpc_completed instead of a sql_batch_completed).

    enter image description here

    If you bind parameters into the SqlCommand it will be sent as an RPC call instead of a batch call, and the events will be a bit different rpc/sp instead of batch/sql.

    rpc_completed/sp_statement_completed
    

    instead of

    sql_batch_completed/sql_statement_completed
