Class RegexReplaceValue

Namespace

The.SQL.QIR.Values

Assembly

Instagile.dll

Replaces every match of the regular expression Pattern in Subject with Replacement. Produced by Regex.Replace(input, pattern, replacement) inside a query projection.

[MessagePackObject(false)]
public sealed class RegexReplaceValue : Value, IEquatable<Value>

Inheritance

object

Value

RegexReplaceValue

Implements

IEquatable<Value>

Inherited Members

Value.CombineAggregates(Aggregated, Aggregated)

Value.IsAggregate

Value.IsHoisted

Value.GetAttribute(IReadOnlyDictionary<string, EntityTable>)

Value.Equals(object)

Value.ToLines()

object.Equals(object, object)

object.GetType()

object.ReferenceEquals(object, object)

Remarks

As with RegexCondition, the regex grammar is backend-specific. Replacement substitution syntax is rewritten from .NET \(1</code>/<code>\)& to POSIX \1. Constant replacements are rewritten to the target dialect at translation time; when they refer to entity data (DynamicReplacement) the PostgreSQL and SQL Server backends instead rewrite it at runtime.

Constructors

RegexReplaceValue(Value, Value, Value, bool, bool)

public RegexReplaceValue(Value input, Value pattern, Value replacement, bool ignoreCase = false, bool dynamicReplacement = false)

Parameters

input Value

pattern Value

replacement Value

ignoreCase bool

dynamicReplacement bool

Fields

DynamicReplacement

Whether Replacement is a runtime value (not a constant) whose .NET substitution syntax still needs converting to the backend dialect at execution time.
