indexing

Looking to create a SQL query that rebuilds indexes in SQL on only one table within my database. Can anyone point me in the right direction. Someone earlier suggested Ola Hallengren SQL maintenance, but I think that is too robust for what I'm after.

There's a difference between REORGANIZE and REBUILD. See this blog post for details.

If you truly want to REBUILD, and you want to do it for ALL indexes on a given table, then the command would be (straight from the official docs that npe pointed you at):

ALTER INDEX ALL ON mySchema.myTable REBUILD
