One example use of this mechanism is to copy the contents of a file into a table column. When set to interactive , such errors are only ignored in interactive sessions, and not when reading script files. These constructs deal correctly with quotes and other special characters embedded within the variable value. See under Environment for how to configure and customize your editor. When set to on , if a statement in a transaction block generates an error, the error is ignored and the transaction continues. If omitted, or if * is specified, all settings are listed, including those not role-specific or database-specific, respectively. So a valid value is any unambiguous case-insensitive match for one of: true , false , 1 , 0 , on , off , yes , no . If value is specified it must be either on or off which will enable or disable tuples-only mode. To set a variable, use the psql meta-command \set . For the sake of readability, it is recommended to always associate a human-readable comment with every object. 直接SQLの内容を渡す方法; 変数を作成してから、実行する。 直接にSQL … This command fetches and shows the definition of the named view, in the form of a CREATE OR REPLACE VIEW command. If set to lower or upper , the completed word will be in lower or upper case, respectively. (This does not apply to lines read interactively.) The auto setting is only effective in the aligned and wrapped formats. Typical values are more or less . (Since the concepts of “ users ” and “ groups ” have been unified into “ roles ” , this command is now equivalent to \dg .) The name of this directory can be set explicitly via the PGSYSCONFDIR environment variable. The target width is determined as described under the columns option. The default setting is ascii . Tab-completion is also supported, although the completion logic makes no claim to be an SQL parser. When this variable is set to on , processing will instead stop immediately. They are not complete documents! If no value is given, the table attributes are unset. In tuples-only mode, only actual table data is shown. If + is appended to the command name, database sizes, default tablespaces, and descriptions are also displayed. If this variable is set to ignorespace , lines which begin with a space are not entered into the history list. The three variables PROMPT1 , PROMPT2 , and PROMPT3 contain strings and special escape sequences that describe the appearance of the prompt. Prompts can contain terminal control characters which, for example, change the color, background, or style of the prompt text, or change the title of the terminal window. 下記のテーブルは存在している前提です。 CREATE TABLE IF NOT EXISTS test (id INTEGER, username VARCHAR (30), age INTEGRE); 手順 数値を渡す場合. Since colons can legally appear in SQL commands, an apparent attempt at interpolation (that is, :name , :'name' , or :"name" ) is not replaced unless the named variable is currently set. If you use the \o command to redirect your query output you might wish to use \qecho instead of this command. The default is platform-dependent. See the section Variables for details. Variables that control psql's behavior generally cannot be unset or set to invalid values. To intersperse text output in between query results, use \qecho . (The expansion of this value might change during a database session as the result of the command SET SESSION AUTHORIZATION .). Sets the header drawing style for the unicode line style to one of single or double . When no dot appears, then the pattern matches only objects that are visible in the current schema search path. If value is omitted the command toggles between the on and off settings. When the data is wrapped from one line to the next without a newline character, an ellipsis symbol is shown in the right-hand margin of the first line, and again in the left-hand margin of the following line. If this variable is set to an integer value greater than zero, the results of SELECT queries are fetched and displayed in groups of that many rows, rather than the default behavior of collecting the entire result set before display. This is set every time you connect to a database (including program start-up), but can be changed or unset. Execution of each query is subject to ECHO processing. Prompt 2 is issued when more input is expected during command entry, for example because the command was not terminated with a semicolon or a quote was not closed. This makes sure that the new password does not appear in cleartext in the command history, the server log, or elsewhere. The new contents of the query buffer are then re-parsed according to the normal rules of psql, treating the whole buffer as a single line. If set to 1 or less, sending an EOF character (usually Control + D ) to an interactive session of psql will terminate the application. The location of the user's startup file can be set explicitly via the PSQLRC environment variable. matches any single character. Both OIDs and comments can be viewed with the \lo_list command. Read its documentation for further details.). スキーマ（名前空間）をリストします。 patternを指定すると、パターンに名前が一致するスキーマのみがリストされます。 デフォルトでは、ユーザー作成オブジェクトのみが表示されます。 supply a pattern or the S modifier to include system objects. If pattern is specified, only those roles whose names match the pattern are listed. When off or unset, SQL commands are not committed until you explicitly issue COMMIT or END . Sets the field separator for unaligned query output. By convention, all specially treated variables' names consist of all upper-case ASCII letters (and possibly digits and underscores). Lists operators with their operand and result types. The host name of the database server, truncated at the first dot, or [local] if the connection is over a Unix domain socket. Variable names are case-sensitive. But in practice, this additional complication should not be necessary. The arguments of \set are subject to the same substitution rules as with other commands. To retrieve the content of the variable, precede the name with a colon, for example: This works in both regular SQL commands and meta-commands; there is more detail in SQL Interpolation , below. The file name that will be used to store the history list. Note that this may be unsafe: the value of the variable is copied literally, so it can contain unbalanced quotes, or even backslash commands. On Windows, which lacks such a concept, the personal startup file is named %APPDATA%\postgresql\psqlrc.conf . If no argument is specified, the query output is reset to the standard output. The value of the psql variable name . For example, putting: in ~/.psqlrc will cause psql to maintain a separate history for each database. Lists event triggers. Setting this variable to on is equivalent to the command line option -S . PostgreSQLサーバーが別の場所にある場合、これを使用して* .sqlファイルを実行します。 psql -h localhost -d userstoreis -U admin -p 5432-a -q -f / home / jobs / Desktop / resources / postgresql. \set without any arguments displays the names and values of all currently-set psql variables. 何千ものINSERTステートメントを含むいくつかの.sqlファイルがあり、それらをテーブルに追加するためにPostgreSQLデータベースでこれらの挿入を実行する必要があります。ファイルは非常に大きいため、それらを開いてINSERTステートメントをエディターウィンドウにコピーし、そこで実行することは不可能です。私はインターネット上で、PostgreSQLインストールのbinフォルダーに移動して以下を使用できることを発見しました。, 次に、ユーザーのパスワードを要求されますが、何も入力できず、Enterキーを押すと、次のエラーが発生します。, なぜパスワードを入力させないのですか？これらのスクリプトを実行できることが重要なので、これを回避する方法はありますか？, この問題を回避するには、次の構造でpg_hba.confファイルに新しいエントリを追加します。, pg_hba.confファイルは通常、PostgreSQLインストールの「data」フォルダにあります。.

Unlike the normal rules for SQL names, you can put double quotes around just part of a pattern, for instance \dt FOO"FOO"BAR will display the table named fooFOObar .
