API Reference

batchUpdate

Description

Help construct the query syntax for batch updates by using the functions.

batchUpdate($table, $columns, $rows, $conditionArray, $conditionColumn) : \yii\db\Command

Parameters

  • $table: table name
  • $columns: Fields to be processed
  • $rows: The values to be processed
  • $conditionArray: The value of the target field
  • $conditionColumn: The name of the target field

Return Values

  • Returns \yii\db\Command

Usage

We can use batchUpdate via SqlHelper as follows:

// Create SqlHelper Object
$sqlHelper = new \marsapp\helper\sql\SqlHelper();

// Setting batch update data
$query = $sqlHelper->batchUpdate('account', ['c_name', 'age'], [
   ['Mars', 35],
   ['Gunter', 24],
   ['Molly', 25],
 ],[ 1, 2, 3],'id');

// Run batch update
$data = $query->execute();

// Echo last query statement
echo $quiery->getRawSql();
echo "\n";
var_export($data);

SQL syntax

The database syntax constructed by batchUpdate is as follows:

UPDATE `account` SET
`c_name` = CASE `id`
     WHEN 1 THEN 'Mars'
     WHEN 2 THEN 'Gunter'
     WHEN 3 THEN 'Molly'
END,
`age` = CASE `id`
     WHEN 1 THEN 35
     WHEN 2 THEN 24
     WHEN 3 THEN 25
END
WHERE `id` IN (1,2,3);

whereInChunk

Description

Help us split the array by using the functions.

whereInChunk($fieldName, $fieldList, $query, $size) : ActiveQuery

Parameters

  • $fieldName: Field to be processed
  • $fieldList: The values to be processed
  • $query: ActiveQuery
  • $size: Cutting length

Return Values

  • Returns ActiveQuery

Usage

We can use whereInChunk via SqlHelper as follows:

// Setting Arguments
$fieldName = 'pkey';
$fieldList = [1, 2, 3, 4];
$query = ActiveRecord::find();
$size = 3;
$data = \marsapp\helpers\sql\SqlHelper::whereInChunk($fieldName, $fieldList, $query, $size)
    ->asArray()
    ->all();

// Print Query Syntax
echo $query->createCommand()->sql;
echo "\n";
echo $query->createCommand()->getRawSql();
echo "\n";

// Print Data
var_export($data);

SQL syntax

The database syntax constructed by batchUpdate is as follows:

SELECT * FROM `TABLE_NAME`
WHERE
  (`pkey` IN(1, 2, 3)) OR (`pkey` = 4)

timeIntersect

Description

Help construct the query syntax for the intersection of time periods by using the functions.

timeIntersect($sCol, $eCol, $sDate, $eDate, $query) : ActiveQuery

Parameters

  • $sCol: Field name for start date
  • $eCol: Field namd for end date
  • $sDate: Value for start date
  • $eDate: Value for end date
  • $query: ActiveQuery

Return Values

  • Returns ActiveQuery

Usage

We can use timeIntersect via SqlHelper as follows:

// Setting Arguments
$sCol = 'start_date';
$eCol = 'endd_date';
$sDate = '2020-04-01';
$eDate = '2020-04-30';

// Sql Builder
$query = ActiveRecord::find();
$data = \marsapp\helpers\sql\SqlHelper::timeIntersect($sCol, $eCol, $sDate, $eDate, $query)
    ->asArray()
    ->all();

// Print Query Syntax
echo $query->createCommand()->sql;
echo "\n";
echo $query->createCommand()->getRawSql();
echo "\n";

// Print Data
var_export($data);

SQL syntax

The database syntax constructed by batchUpdate is as follows:

SELECT * FROM `TABLE_NAME`
WHERE NOT
  (
    (`start_date` > '2020-04-30') OR(
      (`endd_date` < '2020-04-01') AND(`endd_date` <> '0000-00-00')
    )
  )
