The value i have in that column is a rate. I want to have the format 0.00

Thanks again for your help

Try instead, ELSE TO_NUMBER(TRD.UNLOAD_MILE_RATE,'fm99999.00')...

FYI, if you use SQL*Plus to test the statement, the parser will indicate where the error was found -- a faster way to debug the code.

Hi ajexpert

The UNLOAD_MILE_RATE in TL_RATE_DETAIL is NUMBER(10,2) data type.

Hi dvz,

is SQL*PLUS a module i would have to instal?

I'm pretty new in Oracle sql.

also, i still have:
ORA-00932: inconsistent datatypes: expected NUMBER got CHAR

with:

 CASE TRD.UNLOAD_MILE_RATE
        WHEN '0' THEN ''
        ELSE TO_NUMBER(TRD.UNLOAD_MILE_RATE,'fm99999.00')
      END,

Ok, I was wrong about changing the function, go back to TO_CHAR. Change the THEN '' to THEN NULL, and try again.

SQL*Plus is a client-side terminal session. With the target username, password, target database (SID), and TCP/IP port, one can get into command line mode without any GUI interference. It's a separate discussion, plenty of how-to in the knowledge base and on Oracle.

I will look at this SQL*Plus.

Now with the update query to:

    CASE TRD.UNLOAD_MILE_RATE
        WHEN '0' THEN NULL
        ELSE TO_CHAR(TRD.UNLOAD_MILE_RATE,'fm99999.00')
      END,

I still have:
ORA-00932: inconsistent datatypes: expected NUMBER got CHAR
