Method Detail
__construct() ¶ public
__construct(array $columns, Cake\Database\TypeMap $typeMap)
Constructor
Parameters
-
array
$columns The list of columns that are going to be part of the values.
-
Cake\Database\TypeMap
$typeMap A dictionary of column -> type names
_castToExpression() ¶ protected
_castToExpression(mixed $value, string|null $type = null): mixed
Conditionally converts the passed value to an ExpressionInterface object if the type class implements the ExpressionTypeInterface. Otherwise, returns the value unmodified.
Parameters
-
mixed
$value The value to converto to ExpressionInterface
-
string|null
$type optional The type name
Returns
mixed
_columnNames() ¶ protected
_columnNames(): array
Get the bare column names.
Because column names could be identifier quoted, we need to strip the identifiers off of the columns.
Returns
array
_processExpressions() ¶ protected
_processExpressions(): void
Converts values that need to be casted to expressions
Returns
void
_requiresToExpressionCasting() ¶ protected
_requiresToExpressionCasting(array $types): array
Returns an array with the types that require values to be casted to expressions, out of the list of type names passed as parameter.
Parameters
-
array
$types List of type names
Returns
array
add() ¶ public
add(arrayCake\Database\Query $data): void
Add a row of data to be inserted.
Parameters
-
arrayCake\Database\Query
$data Array of data to append into the insert, or a query for doing INSERT INTO .. SELECT style commands
Returns
void
Throws
Cake\Database\Exception
When mixing array + Query data types.
getDefaultTypes() ¶ public
getDefaultTypes(): array
Gets default types of current type map.
Returns
array
getQuery() ¶ public
getQuery(): Cake\Database\Query|null
Gets the query object to be used as the values expression to be evaluated to insert records in the table.
Returns
Cake\Database\Query|null
getTypeMap() ¶ public
getTypeMap(): Cake\Database\TypeMap
Returns the existing type map.
Returns
Cake\Database\TypeMap
setColumns() ¶ public
setColumns(array $cols): $this
Sets the columns to be inserted.
Parameters
-
array
$cols Array with columns to be inserted.
Returns
$this
setDefaultTypes() ¶ public
setDefaultTypes(array $types): $this
Overwrite the default type mappings for fields in the implementing object.
This method is useful if you need to set type mappings that are shared across multiple functions/expressions in a query.
To add a default without overwriting existing ones
use getTypeMap()->addDefaults()
Parameters
-
array
$types The array of types to set.
Returns
$this

setQuery() ¶ public
setQuery(Cake\Database\Query $query): $this

Parameters
-
Cake\Database\Query
$query The query to set
Returns
$this
setTypeMap() ¶ public
setTypeMap(arrayCake\Database\TypeMap $typeMap): $this
Creates a new TypeMap if $typeMap is an array, otherwise exchanges it for the given one.
Parameters
-
arrayCake\Database\TypeMap
$typeMap Creates a TypeMap if array, otherwise sets the given TypeMap
Returns
$this
setValues() ¶ public
setValues(array $values): $this
Sets the values to be inserted.
Parameters
-
array
$values Array with values to be inserted.
Returns
$this
sql() ¶ public
sql(Cake\Database\ValueBinder $generator): string
Convert the values into a SQL string with placeholders.
Parameters
-
Cake\Database\ValueBinder
$generator Placeholder generator object
Returns
string
traverse() ¶ public
traverse(Closure $visitor): $this
Traverse the values expression.
This method will also traverse any queries that are to be used in the INSERT values.
Parameters
-
Closure
$visitor The visitor to traverse the expression with.
Returns
$this
