    RE Like STRPOS doesnt work

    Hello,
    I don't know where your problem is. I know that like works perfectly in a long varchar field. The only problem I ever found is that if you search in lvc with a like lcase(<string>) DB2 reports UDF_MEMSIZE ist too small (after standard installation) Cause for this is obviously that lcase converts lvc (32K) to a CLOB (1M). STRPOS might do the same. By Default UDF_MEM_SZ is 4K*256 = 1M.
    If this is your Problem you might get SQL0973N as error. The solution for this is to increase UDF_MEM_SZ by using Update DBM CFG. Try and Report the result
