Installation and setup

Requires Neovim v0.11.0 or later.

For keymaps, choose a prefix, eg <leader>m. Make sure it doesn't clash with any existing keymaps/which-key groups!

lazy.nvim

{
"Kurren123/mssql.nvim",
opts= {
-- optionalkeymap_prefix="<leader>m"
},
-- optionaldependencies= { "folke/which-key.nvim" }
}

Packer

require("packer").startup(function()
use({
"Kurren123/mssql.nvim",
-- optionalrequires= { 'folke/which-key.nvim' },
config=function()
require("mssql").setup({ keymap_prefix="<leader>m" })
end,
})
end)

Paq

require("paq")({
"savq/paq-nvim",
"Kurren123/mssql.nvim",
-- optional"folke/which-key.nvim",
})
require("mssql").setup({
-- optionalkeymap_prefix="<leader>m",
})

No package manager

Clone this repo, then:

-- Prepend plugin root to runtimepathvim.opt.rtp:prepend("/path/to/mssql.nvim/")
require("mssql").setup({
-- optionalkeymap_prefix="<leader>m",
})

All mssql keymaps are set up with the prefix first. In the above example, new query would be <leader>mn. If you have which-key installed, then the prefix you provide will be a which-key group.

Lualine

Insert require("mssql").lualine_component into a lualine section (eg lualine_c).

Eg lazyvim:

return {
"nvim-lualine/lualine.nvim",
dependencies= { "Kurren123/mssql.nvim" },
opts=function(_, opts)
table.insert(opts.sections.lualine_c, require("mssql").lualine_component)
returnoptsend,
}

Or Lazy.nvim (without lazyvim):

return {
"nvim-lualine/lualine.nvim",
dependencies= { "Kurren123/mssql.nvim" },
opts= {
sections= {
lualine_c= {
require('mssql').lualine_component,
},
},
},
}

Other status lines (eg heirline)

You can also use require('mssql').lualine_component in other status lines or customise your own (see Kurren123#56 (comment)). It's a table with the following:

{
[1] =function()
-- returns a string of the statusend,
cond=function()
-- returns a bool, of whether to show this status lineend
}

So eg a heirline component would look like:

locallualine_component=require("mssql").lualine_componentlocalmssql_heirline_component= {
provider=lualine_component[1],
condition=lualine_component.cond,
}

mssql.nvim calls vim.cmd("redrawstatus") whenever the status changes, so you don't need to worry about refreshing

Using a keymap that gets overridden later (eg lazyvim)

Lazyvim sets its keymaps after loading the mssql plugin. If you want to use a keymap that lazyvim already uses:

1. Call setup() without a keymap_prefix

2. In your keymaps.lua file, delete the lazyvim keymaps then call set_keymaps. Eg:

   -- delete lua profiler keymaps firstsafe_delete("n", "<leader>dpp")
   safe_delete("n", "<leader>dph")
   safe_delete("n", "<leader>dps")
   require("mssql").set_keymaps("<leader>d")

Usage

You can call the following as key maps typing your prefix first, as user commands by doing :MSSQL <command> or as functions on require("mssql").

Key Map	User Command	Function	Description
n	NewQuery	new_query()	Open a new buffer for sql queries
c	Connect	connect()	Connect the current buffer (you'll be prompted to choose a connection)
x	ExecuteQuery	execute_query()	Execute the selection, or the whole buffer. If you are disconnected, it will try to connect to the default connection in your connections.json.
f	Find	find_object()	Find a table/view/stored procedure/function and generate a script
l	CancelQuery	cancel_query()	Cancel the currently running query.
q	Disconnect	disconnect()	Disconnects the current buffer
s	SwitchDatabase	switch_database()	Prompts, then switches to a database that is on the currently connected server
d	NewDefaultQuery	new_default_query()	Opens a new query and connects to the connection called default in your connections.json. Useful when combined with the promptForDatabase option in the connections.json.
s	SaveQueryResults	save_query_results()	When in a query result buffer, save the query result by giving a file path with an extension of .csv, .json, .xml, .xlsx or .xls
r	RefreshCache	refresh_cache()	Rebuild the intellisense and sql object (used for the Find function) caches
e	EditConnections	edit_connections()	Open the connections file for editing
	BackupDatabase	backup_database()	Inserts an SQL command to back up the currently connected database
	RestoreDatabase	restore_database()	Prompts for a .bak file, then inserts an SQL command to restore the database from that file

Connections json file

The format is "connection name": connection object. Eg:

{
"Connection A": {
"server": "localhost",
"database": "dbA",
"authenticationType": "SqlLogin",
"user": "Admin",
"password": "Your_Password",
"trustServerCertificate": true
},
"Connection B": {
"server": "AnotherServer",
"database": "dbB",
"authenticationType": "Integrated",
"promptForDatabase": true
}
}

Each connection object takes standard connection properties. On top of those, you can also provide these useful properties:

Property	Type	Description
promptForDatabase	bool	After connecting to the server, select which database to connect to.
promptForPassword	bool	Ask for the password each time you connect instead of storing it in the json file

Options

Setup with options:

require("mssql").setup({
keymap_prefix="<leader>m",
max_rows=50,
max_column_width=50
})
-- With callbackrequire("mssql").setup({
keymap_prefix="<leader>m",
max_rows=50,
max_column_width=50,
}, function()
print("mssql.nvim is ready!")
end)

See here for all options and defaults

Notes

• setup() runs asynchronously as it may take some time to first download and extract the sql tools. Pass a callback as the second argument if you need to run code after initialization.
• Formatting options are passed into the option's lsp_settings

Supporting this project

I don't take personal donations as I feel like it ruins the fun. However, if you've already given a ⭐ and want to support this project further, please consider donating to the mssql.nvim fundraising page for Cancer Research UK.

Cancer affects millions of lives every year. Any research we can do into beating it also has knock-on effects on enhancing our understanding of other diseases. Seeing anyone donate will make this project worth it.
