sql - dbext 似乎认为 ( 是一个sql语句终止符

Question

我的缓冲区中的 .sql 文件中有此内容:

 CREATE TABLE WH.dbo.customer(
        id              INTEGER NOT NULL,
        cust_name       VARCHAR(30) NOT NULL,
        phone_nbr       VARCHAR(30) NULL,
        PRIMARY KEY(id)
    );

如果我处于正常模式并且光标位于 TABLE那么我应该能够点击 <Leader>se或命令 gVim 至 :DBExecSQLUnderCursor并且该语句应该执行，因为 dbext 应该找到 CREATE和;然后执行中间的脚本。但我收到以下消息:

Last SQL:
CREATE TABLE WHAnalysis.dbo.customer(

如果我突出显示所有脚本并从插件菜单中选择“执行 SQL”(可视化选择)，则它可以正常运行。

这是怎么回事？难道是我的_vimrc中的一个设置？:

Answer 1

我与插件维护者 David Fishburn 进行了交谈 - 我对他为帮助像我这样的新手而付出的努力感到惊讶:伟大的人。

最初他建议

I believe the cmd terminator for SQLSRV is "\ngo\n" not ";".

If you want to change it temporarily to try in this buffer run: :DBSetOption cmd_terminator=';'

Try the cmd again.

If that works you can either override the default or change your profile to override it.

然后回答一些进一步的相关问题:

Q1. What is "\ngo\n" ?

Because the string is enclosed in double quotes, Vim treats escaped characters differently. \n - newline go \n - newline

So for SQL Server this would be typical:

CREATE PROCEDURE BEGIN END go

Which is actually:
"END\ngo\n"

In other words, "go" has to be on a newline, with only "go" on the line.

Q2. Do I just add the following to _vimrc for it to become permanent?:

DBSetOption cmd_terminator=';'

没有。 :DBSetOption 仅用于修改当前缓冲区设置，不用于修改 永久设置。

您能做的最好的事情就是通读 :h dbext.txt。

您的问题的具体答案在于:h dbext-configure-options

5.3 数据库特定选项dbext-configure-options 命令终止符会在命令执行之前自动添加到命令中 发送到数据库。命令选项也添加到命令中 用于执行语句的行。 >

    dbext_default_SQLSRV_bin               = "osql"
    dbext_default_SQLSRV_cmd_header        = ""
    dbext_default_SQLSRV_cmd_terminator    = "\ngo\n"
    dbext_default_SQLSRV_cmd_options       = '-w 10000 -r -b -n'
    dbext_default_SQLSRV_extra             = ''

因此，要永久覆盖 .vimrc 中的所有缓冲区，您需要 添加:
让 g:dbext_default_SQLSRV_cmd_terminator = ";"
