Sorry Richard I meant to send this to the group
Hello, Last week I raised an issue about case sensitivity in where clauses. In doing a little research I happened to talk to an Oracle DBA here where I work and asked him the question of how Oracle handled case sensitivity . He explained it is handle in the same way and suggested the same fix drop both to lower case and then compare. The next thing is mentions is really what I want to raise, he said the latest release of Oracle allows you to build indexes which include functions. He also said that these new type of indexes were used when the user issued a select statement with a function in the where clause or a like (i.e select Col1, Col2 from tableName where col1 like 'Gr%' or select * from tablename where lower(col1) ='fred' ). Without knowing all the ins and outs of it, this seems like a great feature to have. Any change of having someone look into the possibility of implementing some thing like that? regards Greg ----- Original Message ----- From: D.
