Executing an Alter Table statement generated by dynamic sql to a Linked Server -

-

i have situation need add field table on linked server. specifications of dynamic , being done in tql / stored procedures , can not change. code generating statement fine , if copy paste new ssms window , execute works.. problem need dynamically generate statement (i doing fine, think). need execute statement in sproc, part not working.

here code:

set @altersql = @destinationservername + '.[' + @destinationdbname +'].' + @destinationschemaname + '.sp_executesql n'' alter table '  + @destinationtablename + ' add ' + @tempcolumn + ' int' + char(39)

the above creates when expose via print statement:

addb15.[fsparallel].dbo.sp_executesql n' alter table node add importidentity int'

after create statement use:

exec @altersql

and returns following error:

msg 2812, level 16, state 62, procedure etldynamicimport, line 244 not find stored procedure 'fsparallel.dbo.sp_executesql n' alter table node add importidentity int''.

can please advise on this? on project deadline , have googled no end , can not working.

looks you're missing exec. try:

exec sp_executesql n'alter table fsparallel.dbo.node add importidentity int';
