Question

I have a table with a TEXT column where the contents is just strings of CSV numbers. Example ‘,1,76,77,115,’ Each string can have an arbitrary number of numbers.

I am trying to set up Full Text Indexing so that I can search this column rapidly. This works great. Instead of running queries with

where MY_COL LIKE '%,77,%' and MY_COL LIKE '%,115,%' 

I can do

where CONTAINS(MY_COL,'77 and 115') 

However, when I try to search for a single character it doesn’t work.

where CONTAINS(MY_COL,'1') 

But I know that there should be records returned! I quickly found that I need to edit the Noise file and rebuild the index. But even after doing that it still doesn’t work.

Answer 1

Working with relational databases that way is going to hurt.

Use a proper schema. Either store the values in different rows or use an array datatype for the column.

That will make solving the problem trivial.
