Oracle - 如何使用命令从终端将表保存为csv文件

Question

我有这个过程将表保存到CSV文件但不完美：

sqlplus / as sysdba

set heading off

SET TERMOUT OFF
spool MY_TABLE.csv

select column_id||','||column_name||','||data_type||','||nullable||','||data_length from user1.MY_TABLE;

spool off;

exit

问题是无法关闭打印到终端（我有SET TERMOUT OFF但由于某种原因不能抑制输出）。我想从终端运行带有查询的sqlplus（而不是打开sqlplus并从那里运行）.. 怎么做？

Answer 1

linux create_csv.sh的示例1在监视器屏幕上显示表数据。

    #!/bin/sh

    sqlplus -s /  as sysdba <<EOF
    set heading off
    set termout OFF
    SET FEEDBACK OFF
    SET TAB OFF
    set pause off
    set verify off
    SET UNDERLINE OFF
    set trimspool on
    set timing off
    set echo off
    set linesize 1000
    set pagesize 0
    SET COLSEP ','
    spool test2.csv
    select code,name,code_rail from alexs.all_station;
    spool off
    exit;
    EOF

linux createv2_csv.sh的示例2不显示任何内容。

#!/bin/sh

$ORACLE_HOME/bin/sqlplus -s /  as sysdba @csv2.sql

csv2.sql删除了输出文件test2.csv中字段之间的空格和制表符

set heading off
set termout OFF
SET FEEDBACK OFF
SET TAB OFF
set pause off
set verify off
SET UNDERLINE OFF
set trimspool on
set echo off
set linesize 1000
set pagesize 0
set wrap off
spool test2.csv
select code||','||name||','||code_rail from alexs.all_station;
spool off
exit;

Windows test_csv.bat的示例

sqlplus -s  user/password@net_alias  < csv.sql

csv.sql

set heading off
set termout OFF
SET FEEDBACK OFF
SET TAB OFF
set pause off
set verify off
SET UNDERLINE OFF
set trimspool on
set timing off
set echo off
set linesize 1000
set pagesize 0
SET COLSEP ','
spool test.csv
select code,name,code_rail from alexs.all_station;
spool off
exit;

Windows PowerShell脚本create_csv.ps1的示例

# login DBA user
$username_dba = "system"
# PASSWORD DBA user !!!!
$password_dba = "manager"

# Connect without alias 
$tnsalias_db = "(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = test.com)(PORT = 1521)))(CONNECT_DATA = (SID = test)))"

$sqlQuery = 
@"
set heading off
set termout OFF
SET FEEDBACK OFF
SET TAB OFF
set pause off
set verify off
SET UNDERLINE OFF
set trimspool on
set timing off
set echo off
set linesize 1000
set pagesize 0
SET COLSEP ','
spool test.csv
select code,name,code_rail from alexs.all_station;
spool off
exit
"@

$sqlOutput = $sqlQuery | sqlplus -silent $username_dba/$password_dba@$tnsalias_db

示例输出test.csv
