sqlplus在啟動時會自動運(yùn)行兩個腳本:glogin.sql、login.sql這兩個文件
執(zhí)行順序?yàn)?/strong>
1.默認(rèn)在在$ORACLE_HOME/sqlplus/admin路徑下查找glogin.sql文件執(zhí)行
2.默認(rèn)在在當(dāng)前路徑下查找login.sql文件執(zhí)行，若未查找到對應(yīng)文件則執(zhí)行3
3.判斷是否設(shè)置SQLPATH環(huán)境變量，如果設(shè)置了該變量則在對應(yīng)路徑下查找并執(zhí)行，未找到則停止查找
可以在login.sql文件中加入一些常用設(shè)置使用SQLPLUS時更便捷，以下試驗(yàn)在ORACLE 11.2.0.1.0上進(jìn)行
默認(rèn)$ORACLE_HOME/sqlplus/admin路徑下存在glogin.sql文件
當(dāng)前用戶的profile文件中設(shè)置SQLPATH環(huán)境變量 export SQLPATH=$ORACLE_HOME/sqlplus/admin:$SQLPATH
在默認(rèn)路徑下加入我們自己的login.sql文件，以下配置為常用配置
--SQLPLUS默認(rèn)編輯器設(shè)置為videfine _editor=vi--默認(rèn)打開DBMA_OUTPUT,這樣不必要每次在輸入這個命令，同時將默認(rèn)緩沖池設(shè)置得盡可能大set serveroutput on size 1000000--假脫機(jī)輸出文本時，會去除文本行兩端的空格，而且行寬不定，如果設(shè)置為off（默認(rèn)設(shè)置），假脫機(jī)輸出的文本行寬度則等于所設(shè)置的linesizeset trimspool on--設(shè)置選擇LONG和CLOB列時顯示的默認(rèn)字節(jié)數(shù)set long 5000--設(shè)置顯示的文本寬為200個字符set linesize 200--設(shè)置SQLPLUS多久打印一次標(biāo)題，將此參數(shù)設(shè)置大些這樣每頁只顯示一次標(biāo)題set pagesize 9999--設(shè)置AUTOTRACE得到解釋計劃輸出的默認(rèn)寬度，一般80足夠放下整個計劃column plan_plus_exp format a80--設(shè)置SQLPLUS提示符，顯示格式為用戶@數(shù)據(jù)庫名column global_name new_value gnameset termout offdefine gname=idlecolumn global_name new_value gnameselect lower(user) ||'@'|| substr(global_name,1,decode(dot,0,length(global_name),dot-1)) global_namefrom (select global_name,instr(global_name,'.') dot from global_name);set sqlprompt '&gname>'set termout on

可以看到登錄之后 SQLPLUS按照login.sql文件進(jìn)行相應(yīng)設(shè)置
以上所述是小編給大家分享的Oracle SqlPlus設(shè)置Login.sql的技巧，希望對大家有所幫助。
