    Does anyone have a script that will spool out a ctl file by giving a table name ? I'm looking for something that is easy and straight forward. I would appreciate any help.

    I don't think a table name is enough. You also need the datafile and the strucure of the data in the datafile.

    ofcourse u need the structure of the table. I'm looking for a shell script that will just ask you to enter the table name then it will do the rest.

    -- Prepares a SQL*Loader Control FILE FOR a TABLE already existing IN the
    -- DATABASE. The script accepts the TABLE name AND automatically creates a FILE
    -- WITH the TABLE name AND extension 'ctl'.
    -- DEFAULT choices FOR the FILE are AS follows (ALTER TO your needs):
    -- Delimiter: comma (',')
    -- INFILE FILE extension: .dat
    -- DATE format: 'MM/DD/YY'
    --
    -- You may define the Loader Data Types OF the other Data Types BY revising the
    -- DECODE FUNCTION pertaining TO them.
