DECLARE @topsql nvarchar(200)

SET @topsql =

'DECLARE @quotedvar nvarchar(100) ' + char(13) +

'DECLARE @sql nvarchar(1000) ' + char(13) +

'SET @quotedvar = ''O''''Neil''' + char(13) +

'SET @sql = ''PRINT '''''' + REPLACE(@quotedvar,'''''''','''''''''''') + '''''''''+ char(13) +

'PRINT @sql ' + char(13) +

'EXEC sp_executesql @sql '

PRINT @topsql

PRINT '-------'

EXEC sp_executesql @topsql
