Not show columns only tables

[4DRIAN0RTIZ]

**Description of the ruling
When typing inside neovim the autocomplete is not displayed for columns, only for tables.

Reproduce.
Steps to reproduce the behavior:

1. Go to 'playground.sql'.
2. Type 'SELECT * FROM _users;' 3. 3.
3. See error

**Expected behavior
When I go back to the '*' I expected it to take the available columns for the table. As SQL-Server does

My Neovim configuration:

local lspconfig = require('lspconfig')
local lsp_installer = require('nvim-lsp-installer')

lspconfig.html.setup{}
lspconfig.ts_ls.setup{}

lsp_installer.setup({
    automatic_installation = true,
    ui = {
        icons = {
            server_installed = "✓",
            server_pending = "➜",
            server_uninstalled = "✗"
        }
    }
})

lspconfig.sqls.setup({
    cmd = {"sqls"},
    on_attach = function(client, bufnr)
        require('sqls').on_attach(client, bufnr) -- require sqls.nvim
    end,
    settings = {
        sqls = {
            connections = {
                {
                    driver = 'mssql',
                    dataSourceName = 'sqlserver://<username>:<password>@<server>:<port>?database=<DB_NAME>&encrypt=true&trustServerCertificate=true',
                },
                {
                    driver = 'mssql',
                    dataSourceName = 'sqlserver://<username>:<password>@<server>:<port>?database=<DB_ANOTHER_NAME>&encrypt=true&trustServerCertificate=true',
                },
