ValueProcessorOptions

Options object for ValueProcessorByRule functions.

Extends

Properties

concatOperator?

optional concatOperator: string & {} | "||" | "+" | "CONCAT"

Operator to use when concatenating wildcard characters and field names in "sql" format. The ANSI standard is ||, while SQL Server uses +. MySQL does not implement a concatenation operator by default, and therefore requires use of the CONCAT function.

If concatOperator is set to "CONCAT" (case-insensitive), the CONCAT function will be used. Note that Oracle SQL does not support more than two values in the CONCAT function, so this option should not be used in that context. The default setting ("||") is already compatible with Oracle SQL.

Default

'||'

Inherited from

FormatQueryOptions.concatOperator

Defined in

packages/react-querybuilder/src/types/importExport.ts:193


context?

optional context: Record<string, any>

Inherited from

FormatQueryOptions.context

Defined in

packages/react-querybuilder/src/types/importExport.ts:199


escapeQuotes?

optional escapeQuotes: boolean

Defined in

packages/react-querybuilder/src/types/importExport.ts:207


fallbackExpression?

optional fallbackExpression: string

This string will be inserted in place of invalid groups for non-JSON formats. Defaults to '(1 = 1)' for "sql"/"parameterized"/"parameterized_named" and '$and:[{$expr:true}]' for "mongodb".

Inherited from

FormatQueryOptions.fallbackExpression

Defined in

packages/react-querybuilder/src/types/importExport.ts:129


fieldData?

optional fieldData: FullField<string, string, string, Option<string>, Option<string>>

The full field object, if fields was provided in the formatQuery options parameter.

Defined in

packages/react-querybuilder/src/types/importExport.ts:212


fieldIdentifierSeparator?

optional fieldIdentifierSeparator: string

When used in conjunction with the quoteFieldNamesWith option, field names will be split by this string, each part being individually processed as per the rules of the quoteFieldNamesWith configuration. The parts will then be re-joined by the same string.

A common value for this option is '.'.

A value of '' (the empty string) will disable splitting/rejoining.

Default

''

Example

formatQuery(query, {
format: 'sql',
quoteFieldNamesWith: ['[', ']'],
fieldIdentifierSeparator: '.',
})
// "[dbo].[Musicians].[First name] = 'Steve'"

Inherited from

FormatQueryOptions.fieldIdentifierSeparator

Defined in

packages/react-querybuilder/src/types/importExport.ts:95


fieldParamNames?

optional fieldParamNames: Record<string, string[]>

Included for the "parameterized_named" format only. Keys of this object represent field names and values represent the current list of parameter names for that field based on the query rules processed up to that point. Use this list to ensure that parameter names generated by the custom rule processor are unique.

Defined in

packages/react-querybuilder/src/types/importExport.ts:219


fields?

optional fields: FlexibleOptionList<FullField<string, string, string, Option<string>, Option<string>>>

This can be the same FullField array passed to QueryBuilder, but really all you need to provide is the name and validator for each field.

The full field object from this array, where the field's identifying property matches the rule's field, will be passed to the rule processor.

Inherited from

FormatQueryOptions.fields

Defined in

packages/react-querybuilder/src/types/importExport.ts:113


format?

optional format: ExportFormat

The ExportFormat.

Inherited from

FormatQueryOptions.format

Defined in

packages/react-querybuilder/src/types/importExport.ts:43


getNextNamedParam()?

optional getNextNamedParam: (field: string) => string

Included for the "parameterized_named" format only. Call this function with a field name to get a unique parameter name, as yet unused during query processing.

Parameters

ParameterType
fieldstring

Returns

string

Defined in

packages/react-querybuilder/src/types/importExport.ts:224


numberedParams?

optional numberedParams: boolean

Renders parameter placeholders as a series of sequential numbers instead of '?' like the default. This option will respect the paramPrefix option like the 'parameterized_named' format.

Default

false

Inherited from

FormatQueryOptions.numberedParams

Defined in

packages/react-querybuilder/src/types/importExport.ts:161


paramPrefix?

optional paramPrefix: string

This string will be placed in front of named parameters (aka bind variables) when using the "parameterized_named" export format.

Default

":"

Inherited from

FormatQueryOptions.paramPrefix

Defined in

packages/react-querybuilder/src/types/importExport.ts:136


paramsKeepPrefix?

optional paramsKeepPrefix: boolean

Maintains the parameter prefix in the params object keys when using the "parameterized_named" export format. Recommended when using SQLite.

Default

false

Example

console.log(formatQuery(query, {
format: "parameterized_named",
paramPrefix: "$",
paramsKeepPrefix: true
}).params)
// { $firstName: "Stev" }
// Default (`paramsKeepPrefix` is `false`):
// { firstName: "Stev" }

Inherited from

FormatQueryOptions.paramsKeepPrefix

Defined in

packages/react-querybuilder/src/types/importExport.ts:153


parseNumbers?

optional parseNumbers: boolean

Renders values as either number-types or unquoted strings, as appropriate and when possible. Each string-type value is evaluated against numericRegex to determine if it can be represented as a plain numeric value. If so, parseFloat is used to convert it to a number.

Inherited from

FormatQueryOptions.parseNumbers

Defined in

packages/react-querybuilder/src/types/importExport.ts:168


placeholderFieldName?

optional placeholderFieldName: string

Any rules where the field is equal to this value will be ignored.

Default

'~'

Inherited from

FormatQueryOptions.placeholderFieldName

Defined in

packages/react-querybuilder/src/types/importExport.ts:174


placeholderOperatorName?

optional placeholderOperatorName: string

Any rules where the operator is equal to this value will be ignored.

Default

'~'

Inherited from

FormatQueryOptions.placeholderOperatorName

Defined in

packages/react-querybuilder/src/types/importExport.ts:180


preset?

optional preset: SQLPreset

Option presets to maximize compatibility with various SQL dialects.

Inherited from

FormatQueryOptions.preset

Defined in

packages/react-querybuilder/src/types/importExport.ts:197


quoteFieldNamesWith?

optional quoteFieldNamesWith: string | [string, string]

In the "sql", "parameterized", "parameterized_named", and "jsonata" export formats, field names will be bracketed by this string. If an array of strings is passed, field names will be preceded by the first element and succeeded by the second element.

Tip: Use fieldIdentifierSeparator to bracket identifiers individually within field names.

Default

'' // the empty string

Examples

formatQuery(query, { format: 'sql', quoteFieldNamesWith: '"' })
// `"First name" = 'Steve'`
formatQuery(query, { format: 'sql', quoteFieldNamesWith: ['[', ']'] })
// "[First name] = 'Steve'"

Character to use for quoting string values in the SQL format.

Default

'

Inherited from

FormatQueryOptions.quoteValuesWith

Defined in

packages/react-querybuilder/src/types/importExport.ts:100

optional wrapValueWith: [string, string]

Additional prefix and suffix characters to wrap the value in. Useful for augmenting the default value processor results with special syntax (e.g., for dates or function calls).

Methods

getOperators()?

optional getOperators(field: string, misc: { fieldData: FullField<string, string, string, Option<string>, Option<string>>; }): null | FlexibleOptionList<FullOperator<string>>

This can be the same getOperators function passed to QueryBuilder.

The full operator object from this array, where the operator's identifying property matches the rule's operator, will be passed to the rule processor.
