sql - 运行 sql 文件而不打印其内容 POSTGRES

Question

如何在不将其内容打印到屏幕的情况下运行 .sql 文件我正在使用此命令运行 .sql 文件

psql -h localhost -U usrcashlink -d db_cashlink -a -f /home/cashlink/jenkins_node/cashlink_teste/cashlink_testes/src/test/resources/br/com/softbox/cashlink/massadados/massa_antes.sql

但是它正在将整个文件内容打印(记录)到屏幕上。如何在不打印其内容的情况下执行此 .sql 文件。

Answer 1

至少从您的调用中跳过选项 -a，从而代替:

psql -h localhost -U usrcashlink -d db_cashlink -a -f /path/to/file.sql

尝试:

psql -h localhost -U usrcashlink -d db_cashlink -f /path/to/file.sql

您可以随时询问 psql 参数的含义以及可用的内容。在我的系统上:

$ 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: "sthagen")
  -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
                           (e.g., -v ON_ERROR_STOP=1)
  -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[=options]     show this help, then exit
      --help=commands      list backslash commands, then exit
      --help=variables     list special variables, then exit

Input and output options:
  -a, --echo-all           echo all input from script
  -b, --echo-errors        echo failed commands
  -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
                           field separator for unaligned output (default: "|")
  -H, --html               HTML table output mode
  -P, --pset=VAR[=ARG]     set printing option VAR to ARG (see \pset command)
  -R, --record-separator=STRING
                           record separator for unaligned output (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 for unaligned output to zero byte
  -0, --record-separator-zero
                           set record separator for unaligned output to zero byte

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

For more information, type "\?" (for internal commands) or "\help" (for SQL
commands) from within psql, or consult the psql section in the PostgreSQL
documentation.

另一个选项总是在 shell 级别，用于将标准输出和标准错误重定向到文件或 /dev/null 以完全不使用它......像这样:

psql -h localhost -U usrcashlink -d db_cashlink -f /path/to/file.sql 1>out.txt 2>err.txt
