Ability to check exists through tables with "through" key. #30
Conversation
Checking exists changed to join, since it's insanely much faster (from tens or hundreds of seconds to milliseconds). Checking not exists is as before. Through works with unlimited number of pivot tables. Example: 'join2through' => array( 'from_table' => 'master2', 'from_col' => 'm2_col', 'to_table' => 'subtable2', 'to_col' => 's2_col', 'to_value_column' => 's2_value', 'not_exists' => true, 'through' => array( 'from_table' => 'subtable2', 'from_col' => 's2_col', 'to_table' => 'subtable3', 'to_col' => 's3_col', 'to_value_column' => 's3_value', ) ), Keep adding "through" if there's more tables in between.

The failed tests comes from the fact that the tests check for exists, instead of how it's done now. I didn't want to rewrite the tests, in case you're not going to accept this pull request. |

One thing that I am cautious of is that this code looks like it will change the behavior for other users of this class.
Can we separate out the code inside the if() {...} block into two separate functions to ensure that the length of this function (buildSubclauseQuery) is not too long?

Please try to keep lines < 80 characters long. This line of code wraps in my browser.

Also, with this project, we are trying to stick to PSR-2 styling (https://www.php-fig.org/psr/psr-2/). Could you please ensure that you are using spaces and not tabs to format code?

Through works with unlimited number of pivot tables.
Example:
'join2through' => array(
'from_table' => 'master2',
'from_col' => 'm2_col',
'to_table' => 'subtable2',
'to_col' => 's2_col',
'to_value_column' => 's2_value',
'not_exists' => true,
'through' => array(
'from_table' => 'subtable2',
'from_col' => 's2_col',
'to_table' => 'subtable3',
'to_col' => 's3_col',
'to_value_column' => 's3_value',
)
),
Keep adding "through" if there's more tables in between.
