Dynamic SQL Not Converting VARCHAR To INT (shouldn't anyway)

Question

I\'m receiving an error:

Conversion failed when converting the varchar value \'INSERT INTO TableRowCount (IntFieldID, DecimalField) SELECT \'to data t

Answer 1

A better way than trying to concatenate an integer is to pass it in as a strongly-typed parameter:

DECLARE @start INT = 1;

DECLARE @sql NVARCHAR(MAX) = N'INSERT ...
  SELECT @start, COUNT(*) FROM ' + @conn;

EXEC sp_executesql @sql, N'@start INT', @start;
