I am using 10g release of Oracle .

I am using clob data inside a package and I am printing it . I am also doing certain manipulations on the same like substr and instr .

Will using dbms_lob package functions like instr,read,getlength improve peformance or can i use normal string functions itself on the clob type

The clob type normally is used to print xml data which is huge .

Pls suggest which one would be better for performance .

In 10g, you can use standard character function on CLOB.

As possible. You always have to scan the string.
