Walter,

Investigate the DBMS_LOB supplied package.

The Instr function in that package does exactly what you want.

I've been through the documentation on LOBs but am still stuck trying to figure out how to interrogate the contents of a BLOB.

We have a table with a BLOB column in it. All it contains in text data (i.e. memo notes). Why it was created as a BLOB and not a CLOB is unknown to me and done before I was hired. All I need to do is determine if a particular string ('.com') pattern exists in the column, within the first 75 bytes, and return its starting position.

Would someone help me out? Thanks!
