Question

我试图在变量中保存查询的输出。我在stackoverflow中遵循了一些答案，但没有运气。目前我正在使用这个

billerrors=$(sqlplus -s $username/$password@$SID << EOF
set pagesize 0 feedback off verify off heading off echo off;
SELECT ERROR from temp_table
exit;
EOF
)

echo $billerrors

我总是得到的输出是

SQL Plus：版本11.2.0.1.0生产版权所有（c）1982,2009，甲骨文。版权所有。使用SQL Plus执行SQL，PL / SQL和 SQL * Plus语句。

来自temp_table的上述查询SELECT ERROR的输出将采用以下格式

Bill payment errors in the last 30 minutes: XX : 70. YY : 20.

如果没有账单错误，输出将是

Bill payment errors in the last 30 minutes: 0.

如果有人能提供帮助我真的很感激

您在变量用户名和密码的脚本中使用了错误的名称。如果在脚本中使用变量用户名和密码的正确名称，那么您的脚本必须正常工作。

示例1 。在脚本中为变量$username和$password更正名称。

  #!/bin/sh

username=SCOTT
password=Tiger
## esmd is TNS alias in tnsnames.ora
SID=esmd

echo username:  $username
echo password:  $password
echo tns:       $SID

billerrors=$(sqlplus -s $username/$password@$SID  << EOF
set pagesize 0 feedback off verify off heading off echo off;
show user;
SELECT 'Date: '||to_char(sysdate,'DD-MM-YYYY HH24:MI')||' The test is passed' from dual;
exit;
EOF
)

echo $billerrors

    oracle@esmd:~> ./test.sh
    username: SCOTT
    password: Tiger
    tns: esmd
    USER is "SCOTT" Date: 25-01-2018 08:32 The test is passed

示例2。 当我调用sqlplus

时，我在变量$UserName的名称中出错

#!/bin/sh

username=SCOTT
password=Tiger
## esmd is TNS alias in tnsnames.ora
SID=esmd

echo username:  $username
echo password:  $password
echo UserName:  $UserName
echo tns:       $SID

billerrors=$(sqlplus -s $UserName/$password@$SID  << EOF
set pagesize 0 feedback off verify off heading off echo off;
show user;
SELECT 'Date: '||to_char(sysdate,'DD-MM-YYYY HH24:MI')||' The test is passed' from dual;
exit;

)

            SQL*Plus: Release 11.2.0.3.0 Production Copyright (c) 1982, 2011, Oracle. All rights reserved. Use SQL*Plus to execute SQL, PL/SQL and SQL*Plus 
        statements. Usage 1: sqlplus -H | -V -H Displays the SQL*Plus version and the 
        usage help. -V Displays the SQL*Plus version. Usage 2: sqlplus [ [<option>] [{logon | /nolog}] [<start>] ] <option> is: [-C <version>] [-L] [-M "<options>"] 
        [-R <level>] [-S] -C <version> Sets the compatibility of affected commands to the version specified by <version>. The version has the form "x.y[.z]". 
For example, -C 10.2.0 -L Attempts to log on just once, instead of reprompting 
on error. -M "<options>" Sets automatic HTML markup of output. The options have the form: HTML [ON|OFF] [HEAD text] [BODY text] [TABLE text] [ENTMAP {ON|OFF}] 
[SPOOL {ON|OFF}] [PRE[FORMAT] {ON|OFF}] -R <level> Sets restricted mode to disable SQL*Plus commands that interact with the file system. The level can be 
1, 2 or 3. The most restrictive is -R 3 which disables all user commands 
interacting with the file system. -S Sets silent mode which suppresses the 
display of the SQL*Plus banner, prompts, and echoing of commands. <logon> is: 
{<username>[/<password>][@<connect_identifier>] | / } [AS {SYSDBA | SYSOPER | SYSASM}] [EDITION=value] Specifies the database account username, password and connect identifier for the database connection. Without a connect identifier, SQL*Plus connects to the default database. The AS SYSDBA, AS SYSOPER and AS SYSASM options are database administration privileges. <connect_identifier> can be in the form of Net Service Name or Easy Connect. @[<net_service_name> | [//]Host[:Port]/<service_name>] <net_service_name> is a simple name for a service that resolves to a connect descriptor. Example: Connect to database using Net Service Name and the database net service name is ORCL. sqlplus myusername/mypassword@ORCL Host specifies the host name or IP address of the database server computer. Port specifies the listening port on the database server. <service_name> specifies the service name of the database you want to access. Example: Connect to database using Easy Connect and the Service name is ORCL. sqlplus myusername/mypassword@Host/ORCL The /NOLOG option starts SQL*Plus without connecting to a database. The EDITION specifies the value for Session Edition. <start> is: @<URL>|<filename>[.<ext>] [<parameter> ...] Runs the specified SQL*Plus script from a web server (URL) or the local file system (filename.ext) with specified parameters that will be assigned to substitution 
    variables in the script. When SQL*Plus starts, and after CONNECT commands, the 
    site profile (e.g. $ORACLE_HOME/sqlplus/admin/glogin.sql) and the user profile 
    (e.g. login.sql in the working directory) are run. The files may contain 
    SQL*Plus commands. Refer to the SQL*Plus User's Guide and Reference for more 
    information.
