FormatQueryOptions

Options object shape for formatQuery.

Properties

concatOperator?

optional concatOperator: string & object | "||" | "+" | "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

'||'

packages/react-querybuilder/src/types/importExport.ts:186

---

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".

Defined in

packages/react-querybuilder/src/types/importExport.ts:122

---

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'"

Defined in

packages/react-querybuilder/src/types/importExport.ts:88

---

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.

Defined in

packages/react-querybuilder/src/types/importExport.ts:106

---

format?

optional format: ExportFormat

The ExportFormat.

Defined in

packages/react-querybuilder/src/types/importExport.ts:34

---

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

Defined in

packages/react-querybuilder/src/types/importExport.ts:154

---

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

":"

Defined in

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

---

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" }

Defined in

packages/react-querybuilder/src/types/importExport.ts:146

---

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.

Defined in

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

---

placeholderFieldName?

optional placeholderFieldName: string

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

Default

'~'

Defined in

packages/react-querybuilder/src/types/importExport.ts:167

---

placeholderOperatorName?

optional placeholderOperatorName: string

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

Default

'~'

Defined in

packages/react-querybuilder/src/types/importExport.ts:173

---

preset?

optional preset: SQLPreset

Option presets to maximize compatibility with various SQL dialects.

Defined in

packages/react-querybuilder/src/types/importExport.ts:190

---

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.

A common value for this option is the backtick ('`').

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'"

Defined in

packages/react-querybuilder/src/types/importExport.ts:67

---

quoteValuesWith?

optional quoteValuesWith: string

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

Default

'

Defined in

packages/react-querybuilder/src/types/importExport.ts:93

---

ruleProcessor?

optional ruleProcessor: RuleProcessor

This function will be used to process each rule for query language formats. If not defined, the appropriate defaultRuleProcessor for the format will be used.

Defined in

packages/react-querybuilder/src/types/importExport.ts:46

---

validator?

optional validator: QueryValidator

Validator function for the entire query. Can be the same function passed as validator prop to QueryBuilder.

Defined in

packages/react-querybuilder/src/types/importExport.ts:98

---

valueProcessor?

optional valueProcessor: ValueProcessorLegacy | ValueProcessorByRule

This function will be used to process the value from each rule for query language formats. If not defined, the appropriate defaultValueProcessor for the format will be used.

Defined in

packages/react-querybuilder/src/types/importExport.ts:40

Methods

getOperators()?

optional getOperators(field, misc): 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.

Parameters

Parameter	Type
field	string
misc	object
misc.fieldData	FullField<string, string, string, Option<string>, Option<string>>

Returns

null | FlexibleOptionList<FullOperator<string>>

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

caution

API documentation is generated from the latest commit on the main branch. It may be somewhat inconsistent with official releases of React Query Builder.
