你好,我不明白虛擬填充它做什麼?它是什麼做假填充sql加載程序?
有人向我解釋?
load data
infile * "str '</contact>'"
INSERT
into table address_book
TRUNCATE
FIELDS(
dummy1 filler char(2000) terminated by "<contact>",
contact_name char(2000) enclosed by "<contact_name>" and "</contact_name>",
address char(2000) enclosed by "<address>" and "</address>",
dummy2 filler char(2000) terminated by "</start>"
)
BEGINDATA
例如:dummy1填充:這意味着要忽略一切,直到聯繫? 謝謝
Gary_W謝謝。你的答案非常全面 – Dany
