PostgreSQL 使用psql插入参数到sql脚本文件中

1. 数据

postgres=# select * from tb1;
 id  | name 
-----+------
   2 | aa
   3 | aa
   4 | aa
   7 | aa
   8 | aa
   9 | aa
  10 | aa
   1 | cc
   5 | cc
   6 | cc
 100 | vv
(11 rows)

2. 准备sql脚本文件

vi test.sql

写入 select * from tb1 where id=:id; (:+变量名)

保存。

3. 使用psql命令执行sql脚本

[postgres@localhost ~]$ psql postgres postgres -v id=1 -f /home/postgres/test.sql 
 id | name 
----+------
  1 | cc
(1 row)

[postgres@localhost ~]$ psql postgres postgres -v id=2 -f /home/postgres/test.sql 
 id | name 
----+------
  2 | aa
(1 row)

4. psql命令使用-c 调用\i命令

[postgres@localhost ~]$ psql postgres postgres -v id=2 -c '\i /home/postgres/test.sql '
 id | name 
----+------
  2 | aa
(1 row)

5. psql使用文档

[postgres@localhost ~]$ psql --help
psql is the PostgreSQL interactive terminal.

Usage:
  psql [OPTION]... [DBNAME [USERNAME]]

General options:
  -c, --command=COMMAND    run only single command (SQL or internal) and exit
  -d, --dbname=DBNAME      database name to connect to (default: "postgres")
  -f, --file=FILENAME      execute commands from file, then exit
  -l, --list               list available databases, then exit
  -v, --set=, --variable=NAME=VALUE
                           set psql variable NAME to VALUE
  -V, --version            output version information, then exit
  -X, --no-psqlrc          do not read startup file (~/.psqlrc)
  -1 ("one"), --single-transaction
                           execute as a single transaction (if non-interactive)
  -?, --help               show this help, then exit

Input and output options:
  -a, --echo-all           echo all input from script
  -e, --echo-queries       echo commands sent to server
  -E, --echo-hidden        display queries that internal commands generate
  -L, --log-file=FILENAME  send session log to file
  -n, --no-readline        disable enhanced command line editing (readline)
  -o, --output=FILENAME    send query results to file (or |pipe)
  -q, --quiet              run quietly (no messages, only query output)
  -s, --single-step        single-step mode (confirm each query)
  -S, --single-line        single-line mode (end of line terminates SQL command)

Output format options:
  -A, --no-align           unaligned table output mode
  -F, --field-separator=STRING
                           set field separator (default: "|")
  -H, --html               HTML table output mode
  -P, --pset=VAR[=ARG]     set printing option VAR to ARG (see \pset command)
  -R, --record-separator=STRING
                           set record separator (default: newline)
  -t, --tuples-only        print rows only
  -T, --table-attr=TEXT    set HTML table tag attributes (e.g., width, border)
  -x, --expanded           turn on expanded table output
  -z, --field-separator-zero
                           set field separator to zero byte
  -0, --record-separator-zero
                           set record separator to zero byte

Connection options:
  -h, --host=HOSTNAME      database server host or socket directory (default: "/usr/local/postgres-9.3.5/data")
  -p, --port=PORT          database server port (default: "5432")
  -U, --username=USERNAME  database user name (default: "postgres")
  -w, --no-password        never prompt for password
  -W, --password           force password prompt (should happen automatically)
