Unlike most other meta-commands, the entire remainder of the line is always taken to be the argument(s) of \sv, and neither variable interpolation nor backquote expansion are performed in the arguments. psql is a terminal-based front-end to PostgreSQL. In other formats, it always behaves as if the expanded mode is off. Not the answer you're looking for? Treating the buffer as a single line primarily affects meta-commands: whatever is in the buffer after a meta-command will be taken as argument(s) to the meta-command, even if it spans multiple lines. Ordinarily, input lines are sent to the server when a command-terminating semicolon is reached. When program is specified, command is executed by psql and the data passed from or to command is routed between the server and the client. To include a single quote in an argument, write two single quotes within single-quoted text. If n is combined with +, two sizes are shown: one including the total size of directly-attached leaf partitions, and another showing the total size of all partitions, including indirectly attached sub-partitions. Inside the crosstab grid, for each distinct value x of colH and each distinct value y of colV, the cell located at the intersection (x,y) contains the value of the colD column in the query result row for which the value of colH is x and the value of colV is y. For example: If you specify a prefix, that string is prepended to the query's column names to create the variable names to use: If a column result is NULL, the corresponding variable is unset rather than being set. If no such behavior is mentioned, then omitting value just results in the current setting being displayed. When this variable is set to on and a backslash command queries the database, the query is first shown. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA.

The error rollback mode works by issuing an implicit SAVEPOINT for you, just before each command that is in a transaction block, and then rolling back to the savepoint if the command fails. unicode style uses Unicode box-drawing characters. Specifies the record (line) separator to use in unaligned output format. When the pager option is off, the pager program is not used. However, in the case of a non-interactive \connect failure, no parameters are allowed to be re-used later, since the script would likely be expecting the values from the failed \connect to be re-used. The pspg pager (not part of PostgreSQL but available in many open source software distributions) can display the output of \watch if started with the option --stream. The latex format uses LaTeX's tabular environment. If a line number is specified, psql will position the cursor on the specified line of the view definition. Like SELECT MyTable.Column_A AS MyColumn --MyColumn is alias for Column_A FROM Table_A AS MyTable --Like wise MyTable is alias for Table_A WHERE Column_B [Conditional Operator] [Input Value] So, your query should be like If + is appended to the command name, additional properties of the subscriptions are shown. Thus you can construct interesting references such as \set :foo 'something' and get soft links or variable variables of Perl or PHP fame, respectively.

(This does not apply to lines read interactively.) (Use \dconfig * to see all parameters.) The default field separator is '|' (a vertical bar). Turn on the expanded table formatting mode. Most variables that control psql's behavior cannot be unset; instead, an \unset command is interpreted as setting them to their default values. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup.

It causes psql to issue a BEGIN command before the first such option and a COMMIT command after the last one, thereby wrapping all the commands into a single transaction. If none of them is set, the default is to use more on most platforms, but less on Cygwin. In general, the higher the number the more borders and lines the tables will have, but details depend on the particular format. If value is omitted the command toggles between regular and tuples-only output. In interactive mode, psql will return to the command prompt; otherwise, psql will exit, returning error code 3 to distinguish this case from fatal error conditions, which are reported using error code 1. If that is not set either, the default is ~/.psql_history, or %APPDATA%\postgresql\psql_history on Windows. The off behavior is for compatibility with older versions of psql. Within an argument, text that is enclosed in backquotes (`) is taken as a command line that is passed to the shell. If operator-family-pattern is specified, only members of operator families whose names match that pattern are listed.

So for example, results in sending the three SQL commands to the server in a single request, when the non-backslashed semicolon is reached. The optional topic parameter (defaulting to options) selects which part of psql is explained: commands describes psql's backslash commands; options describes the command-line options that can be passed to psql; and variables shows help about psql configuration variables. Unlike most other meta-commands, the entire remainder of the line is always taken to be the argument(s) of \ef, and neither variable interpolation nor backquote expansion are performed in the arguments. But in practice, this additional complication should not be necessary. If the separator character appears in a field's value, that field is output within double quotes, following standard CSV rules. Also, appearances of :'variable_name' are replaced by the variable's value suitably quoted to become a single shell command argument. Print the current query buffer to the standard output. If pattern is specified, only those extended statistics whose names match the pattern are listed. Backslash-semicolon is not a meta-command in the same way as the preceding commands; rather, it simply causes a semicolon to be added to the query buffer without any further processing.
