Creating index if index doesn't exist

I have a problem creating an index with the advantage database server if it doesn't exist with a sql query.

My query looks like this:

 If not Exists(<SELECT Query for amount of indizes for one column>) then 
 Create Index Test on Tablename (No); endif

So I don't use FullTextSearchIndizes,because it is a integer field. Otherwhise it would look like this:

 If not Exists(SELECT * FROM tablename WHERE CONTAINS( * , 'Test' )) then 
 Create Index Test on Tablename (Name) Content; endif

So, my only problem is how do I get the indices. I've read in other DBMS you can use sys.indexes and some other things.

Solution

  • Take a look at the System tables:

    In particular there is a table called system.indexes:
