repeatable read造句
例句與造句
- Prevents non - repeatable reads but phantom rows are still possible
防止不可重復(fù)的讀取，但是仍可以有幻像行。 - This leaves you a choice between read committed and repeatable read
剩下的也就是在“授權(quán)讀取”和“可重復(fù)讀取”之間選擇了。 - Repeatable read - rr
可重復(fù)讀rr - Non repeatable read
不可重復(fù)讀 - By default , mysql uses the repeatable read isolation level for all transactions
默認(rèn)情況下， mysql對(duì)所有事務(wù)使用repeatable read隔離級(jí)別。 - It's difficult to find repeatable read in a sentence. 用repeatable read造句挺難的
- Incorrect concurrency can lead to problems such as dirty reads , phantom reads , and non - repeatable reads
不正確的并發(fā)可能導(dǎo)致臟讀、幻讀和不可重復(fù)讀等問(wèn)題。 - This is an important issue , but using repeatable read isn ' t the only way to resolve it
這是一個(gè)非常重要的問(wèn)題，但是使用可重復(fù)讀取并不是解決問(wèn)題的唯一途徑。 - For example , reading from a read - only look up table doesn t require repeatable read , and uncommitted read is sufficient
比如，讀取只讀的查找表不需要可重復(fù)讀級(jí)別，未提交讀級(jí)別就足夠了。 - Readpast can only be specified in transactions operating at the read committed or repeatable read isolation levels
僅可在運(yùn)行于read committed或repeatable read隔離級(jí)別的事務(wù)中指定readpast 。 - Specifies that a scan is performed with the same locking semantics as a transaction running at repeatable read isolation level
指定事務(wù)在repeatable read隔離級(jí)別運(yùn)行時(shí)，使用相同的鎖定語(yǔ)義執(zhí)行一次掃描。 - If the transaction isolation mode is repeatable read , then the optimizer would base its choice purely on the estimated costs
如果事務(wù)隔離模式是可重復(fù)讀（ repeatable read ） ，那么優(yōu)化器會(huì)將其選擇完全基于估算成本。 - For the four levels of isolation supported , table 6 shows whether phantom , dirty , or non - repeatable read is possible from strongest to weakest
針對(duì)受支持的四種隔離級(jí)別，表6列出了出現(xiàn)幻像讀、臟讀或不可重復(fù)讀的可能性（從高到低） 。 - If the value is set to 1 , then the optimizer behaves as it does for value 0 if the transaction isolation mode is not repeatable read
如果將其值設(shè)置為1 ，那么當(dāng)事務(wù)隔離模式不是可重復(fù)讀（ repeatable read ）時(shí)，優(yōu)化器的行為就與值為0時(shí)一樣。 - For example , if a repeatable read transaction has a shared lock on a row , and the transaction then modifies the row , the shared row lock is converted to an exclusive row lock
例如，如果repeatable read事務(wù)具有用于某行的共享鎖，并且該事務(wù)隨后修改了該行，則共享行鎖便會(huì)轉(zhuǎn)換為排他行鎖。 - Shared locks are held while the data is being read to avoid dirty reads , but the data can be changed before the end of the transaction , resulting in non - repeatable reads or phantom data
在正在讀取數(shù)據(jù)時(shí)保持共享鎖，以避免臟讀，但是在事務(wù)結(jié)束之前可以更改數(shù)據(jù)，從而導(dǎo)致不可重復(fù)的讀取或幻像數(shù)據(jù)。
