How Can I Retrieve the Fully Constructed SQL String from a SqlCommand Object?

Get the constructed SQL statement from the SqlCommand object

In database programming, it can be very useful to get the complete SQL statement that a SqlCommand object will execute. This may be needed for logging purposes, such as diagnosing failed requests, or checking a built query before execution.

One way to achieve this is to manually build the statement using the CommandText and Parameters properties of the SqlCommand object. This involves iterating over the parameters and replacing the parameter names in the CommandText with their corresponding values. The following code snippet demonstrates this approach:

<code class="language-c#">string query = cmd.CommandText;

foreach (SqlParameter p in cmd.Parameters)
{
    query = query.Replace(p.ParameterName, p.Value.ToString());
}</code>

The generated query can now be used for logging or other situations where access to the full SQL statement is required. For example, you can write queries to a log file or display them for analysis and debugging.
