雄辩地获取表架构，获取数组到字符串的转换错误

Question

i'm trying to get a list of the column data types for a certain table. I have noticed eloquent has some methods that do this so i'm trying to use these.

$grammar = DB::connection()->getSchemaBuilder();
$schema = DB::select($grammar->getColumnListing('vehicles'));

However i'm getting the following error when calling getColumnListing :

Array to string conversion

Not too sure where this so called Array is... the method expects a String :

vendor\\laravel\\framework\\src\\Illuminate\\Database\\Schema\\Builder.php

/**
     * Get the column listing for a given table.
     *
     * @param  string  $table
     * @return array
     */
    public function getColumnListing($table)
    {
        $table = $this->connection->getTablePrefix().$table;

        $results = $this->connection->select($this->grammar->compileColumnListing($table));

        return $this->connection->getPostProcessor()->processColumnListing($results);
    }

Answer 1

Laravel only provides a list of column names:

Schema::getColumnListing('vehicles');

You can get more details by installing the doctrine/dbal package:

Schema::getConnection()->getDoctrineSchemaManager()->listTableColumns('vehicles');
