README

EchoQuery offers a streamlined, intuitive interface for developers. It simplifies complex SQL scripting, enhances readability, and accelerates development, making database interactions effortless and efficient for projects of any scale.

Basic Usage

To be able to use the EchoQuery package you need to install it with the following command:

composer require castroitalo/echoquery

To generate a string with your query using EchoQuery just use the methods available:

• Query example:

SELECT
    column_one AS co,
    column_two
FROM
    table_one AS to
WHERE
    column_one = 2
    AND column_two = 5;

• PHP code with EchoQuery example:

// Importing library
use CastroItalo\EchoQuery\Builder;

// Instanciate class
$echo_query = new Builder();
$query = $echo_query->select(
    ['column_one', 'co'],
    ['column_two']
)
    ->from('table_one', 'to')
    ->where('column_one')
    ->equalsTo(2)
    ->and('column_two')
    ->equalsTo(5)
    ->getQuery();

Features

Select and From Statement

The base of any SQL query is the SELECT and FROM statement, you can easily do it with echo query:

Let's create this SQL code into PHP using EchoQuery:

SELECT column_one
FROM table_one

use CastroItalo\EchoQuery\Builder;

$query = (new Builder())->select(
    ['column_one']
)
    ->from('table_one')
    ->getQuery();

Let's make it more simple:

SELECT *
FROM table_one

use CastroItalo\EchoQuery\Builder;

$query = (new Builder())->select(
    ['*']
)
    ->from('table_one')
    ->getQuery();

In this case, every array passed in select method, is a column and its alias, you can pass as much columns as you want:

use CastroItalo\EchoQuery\Builder;

$query = (new Builder())->select(
    ['column_one', 'co'],
    ['column_two', 'ct'],
    ['column_three', 'ctr']
)
    ->from('table_one')
    ->getQuery();

Where statement

You create each WHERE condition at time, if you want to take the column_one data only the data that is greater than 10 you just do:

use CastroItalo\EchoQuery\Builder;

$query = (new Builder())->select(
    ['column_one', 'co'],
    ['column_two', 'ct'],
    ['column_three', 'ctr']
)
    ->from('table_one')
    ->where('column_on')
    ->greaterThan(10)
    ->getQuery();

You can use ->where() method with:

• Comparison operators:

  • ->equalsTo(mixed $value): Builder
  • ->notEqualsTo(mixed $value, string $notEqualsToOperator = '!='): Builder
  • ->lessThan(mixed $value): Builder
  • ->lessThanEqualsTo(mixed $value): Builder
  • ->greaterThan(mixed $value): Builder
  • ->greaterThanEqualsTo(mixed $value): Builder

• Logical operators:

  • ->and(string $columnName): Builder
  • ->or(string $columnName): Builder
  • ->not(string $columnName): Builder

• Pattern matching:

  • ->like(string $pattern): Builder
  • ->notLike(string $pattern): Builder

• Range conditions:

  • ->between(mixed $start, mixed $end): Builder
  • ->notBetween(mixed $start, mixed $end): Builder

• List conditions:

  • ->in(array $list): Builder
  • ->notIn(array $list): Builder

• Null conditions:

  • ->isNull(): Builder
  • ->isNotNull(): Builder

JOINS

To use joins you need to call the JOIN method you want, and specify the table and the JOIN columns like in:

SELECT a.column_one AS co,
    b.column_two AS ct
FROM table_one AS a
WHERE column_one > 10
    INNER JOIN table_two AS b
        ON a.column_one = b.column_one

use CastroItalo\EchoQuery\Builder;

$query = (new Builder())->select(
    ['a.column_one', 'co'],
    ['b.column_two', 'ct'],
)
    ->from('table_one', 'a')
    ->where('column_one')
    ->greaterThan(10)
    ->innerJoin(
        ['table_two', 'b'],
        ['a.column_one', 'b.column_one']
    )
    ->getQuery();

To use JOIN with sub query you just need to use the equivalent sub query JOIN method:

SELECT a.column_one AS co,
    b.column_two AS ct
FROM table_one AS a
WHERE a.column_one > 10
    INNER JOIN (
        SELECT column_one,
            column_two
        FROM table_two
    ) AS b
        ON a.column_one = b.column_one

use CastroItalo\EchoQuery\Builder;

$sub_query = (new Builder())->select(
    ['a.column_one', 'co'],
    ['b.column_two', 'ct'],
)
    ->from('table_one', 'a')
    ->where('column_one')
    ->getQuery();
$query = (new Builder())->select(
    ['a.column_one', 'co'],
    ['b.column_two', 'ct'],
)
    ->from('table_one', 'a')
    ->where('column_one')
    ->greaterThan(10)
    ->innerJoin(
        [$sub_query, 'b'],
        ['a.column_one', 'b.column_one']
    )
    ->getQuery();

• INNER JOIN:

  • ->innerJoin(array ...$joinInfo): Builder
  • ->innerJoinSub(array ...$joinInfo): Builder

• LEFT JOIN:

  • ->leftJoin(array ...$joinInfo): Builder
  • ->leftJoinSub(array ...$joinInfo): Builder

• RIGHT JOIN:

  • ->rightJoin(array ...$joinInfo): Builder
  • ->rightJoinSub(array ...$joinInfo): Builder

• FULL JOIN:

  • ->fullJoin(array ...$joinInfo): Builder
  • ->fullJoinSub(array ...$joinInfo): Builder

• CROSS JOIN:

  • ->crossJoin(array ...$joinInfo): Builder
  • ->crossJoinSub(array ...$joinInfo): Builder

• SELF JOIN:

  • ->selfJoin(array ...$joinInfo): Builder
  • ->selfJoinSub(array ...$joinInfo): Builder

• NATURAL JOIN:

  • ->naturalJoin(array ...$joinInfo): Builder
  • ->naturalJoinSub(array ...$joinInfo): Builder

UNIONS

To use use UNIONS just use the ->union(string $unionQuery): Builder or ->unionAll(string $unionQuery): Builder with the subsequent query as the parameter:

SELECT column_one AS co,
    column_two AS ct,
    column_three AS ctr
FROM table_one AS to
WHERE column_one > 10
UNION
SELECT column_four AS cfr,
    column_five AS cf,
    column_six AS cs
FROM table_two AS tt
WHERE column_five NOT IN (1, 3, 4, 6);

use CastroItalo\EchoQuery\Builder;

$union_query = (new Builder())->select(
    ['column_four', 'cfr'],
    ['column_five', 'cf'],
    ['column_six', 'cs']
)
    ->from('table_two', 'tt')
    ->where('column_five')
    ->notIn([1, 3, 4, 6])
    ->getQuery();
$query = (new Builder())->select(
    ['column_one', 'co'],
    ['column_two', 'ct'],
    ['column_three', 'ctr']
)
    ->from('table_one', 'to')
    ->where('column_one')
    ->greaterThan(10)
    ->union($union_query)
    ->getQuery();

GROUP BY

To use GROUP BY on aggregate functions simply use the ->groupBy(string ...$columns): Builder method, passing one or more columns to group:

SELECT COUNT(column_one) AS co
    SUM(column_two) AS ct
FROM table_one AS to
GROUP BY column_one, column_two

use CastroItalo\EchoQuery\Builder;

$query = (new Builder())->select(
    ['COUNT(column_one)', 'co'],
    ['SUM(column_two)', 'ct']
)
    ->from('table_one', 'to')
    ->groupBy('column_one', 'column_two')
    ->getQuery();

ORDER BY

To use ORDER BY on columns simply use the ->orderBy(array ...$columns): Builder method, passing one or more columns with the respective ordering function.

SELECT column_one AS co,
    column_two AS ct
FROM table_one AS to
ORDER BY column_one,
    column_two DESC

use CastroItalo\EchoQuery\Builder;

$query = (new Builder())->select(
    ['column_one', 'co'],
    ['column_two', 'ct']
)
    ->from('table_one', 'to')
    ->orderBy(
        ['column_one'],
        ['column_two', 'desc']
    )
    ->getQuery();

HAVING

For using HAVING just use the ->having(string $having): Builder with one of the comparison operator:

SELECT COUNT(column_one) AS co,
    column_two AS ct,
    column_three AS ctr
FROM table_one AS to
WHERE column_one > 10
HAVING COUNT(column_one) > 10

use CastroItalo\EchoQuery\Builder;

$query = (new Builder())->select(
    ['COUNT(column_one)', 'co'],
    ['column_two', 'ct'],
    ['column_three', 'ctr']
)
    ->from('table_one', 'to')
    ->where('column_one')
    ->greaterThan(10)
    ->having('COUNT(column_one)')
    ->greaterThan(10)
    ->getQuery();

Pagination

To create a pagination just use the ->pagination(int $limit, ?int $offset = null): Builder method, passing the limit and an optional offset for it:

SELECT column_one AS co,
    column_two AS ct
FROM table_one AS to
LIMIT 10

use CastroItalo\EchoQuery\Builder;

$query = (new Builder())->select(
    ['COUNT(column_one)', 'co'],
    ['column_two', 'ct'],
)
    ->from('table_one', 'to')
    ->where('column_one')
    ->pagination(10)
    ->getQuery();
