Usage: SQLULDR2 keyword=value [,keyword=value,...]

Valid Keywords:

user = username/password@tnsname

sql = SQL file name

query = select statement

field = separator string between fields

record = separator string between records

rows = print progress for every given rows (default, 1000000)

file = output file name(default: uldrdata.txt)

log = log file name, prefix with + to append mode

fast = auto tuning the session level parameters(YES)

text = output type (MYSQL, CSV, MYSQLINS, ORACLEINS, FORM, SEARCH).

charset = character set name of the target database.

ncharset= national character set name of the target database.

parfile = read command option from parameter file

for field and record, you can use '0x' to specify hex character code,

\r=0x0d \n=0x0a |=0x7c ,=0x2c, \t=0x09, :=0x3a, #=0x23, "=0x22 '=0x27

常見幾個例子：

根據查詢語句導出:sqluldr2linux64.bin user=test/test@orcl query="select * from testdb" file="test.txt"

如果查詢sql比較長，則可以把sql語句放入到文件中:sqluldr2linux64.bin user="username/pwd" sql="/home/query.sql" field="0x09" record=0x0a file="/home/table.txt" charset=UTF8
