Question

我有一个sql块（file.sql）：

DO $$
DECLARE 

 var1 varchar;
BEGIN

    var1 := :key;

END $$;

当我用psql调用此.sql时，

psql -h localhost -v key="value" -U user -f file.sql  postgredb

我收到错误：

错误：“：”
处或附近的语法错误

想知道为什么命令行arg没有得到解决

我认为你不能那样做。我创建了一个psql函数，它接受一个varchar参数（例如你的例子中的键），然后我将从终端调用它：

alex@mbpro:~/sdk/tools/bin$ ./sdkmanager --help Usage: sdkmanager [--uninstall] [<common args>] \ [--package_file <package-file>] [<packages>...] sdkmanager --update [<common args>] sdkmanager --list [<common args>] In its first form, installs, or uninstalls, or updates packages. <package> is a sdk-style path (e.g. "build-tools;23.0.0" or "platforms;android-23"). <package-file> is a text file where each line is a sdk-style path of a package to install or uninstall. Multiple --package_file arguments may be specified in combination with explicit paths. In its second form (with --update), currently installed packages are updated to the latest version. In its third form, all installed and available packages are printed out. Common Arguments: --sdk_root=<sdkRootPath>: Use the specified SDK root instead of the SDK containing this tool --channel=<channelId>: Include packages in channels up to <channelId>. Common channels are: 0 (Stable), 1 (Beta), 2 (Dev), and 3 (Canary). --include_obsolete: With --list, show obsolete packages in the package listing. With --update, update obsolete packages as well as non-obsolete. --no_https: Force all connections to use http rather than https. --proxy=<http | socks>: Connect via a proxy of the given type. --proxy_host=<IP or DNS address>: IP or DNS address of the proxy to use. --proxy_port=<port #>: Proxy port to connect to. * If the env var REPO_OS_OVERRIDE is set to "windows", "macosx", or "linux", packages will be downloaded for that OS.

然后你可以将所有这些包装在函数的某个bash脚本中，以便你可以更快地调用它。

希望有所帮助，欢呼。
