import {EditorView, basicSetup} from "codemirror"
import {sql} from "@codemirror/lang-sql"
const view = new EditorView({
 parent: document.body,
 doc: `select * from users where age > 20`,
 extensions: [basicSetup, sql()]
})

Use sql({dialect: PostgreSQL}) or similar to select a specific SQL dialect.

sql (config⁠?: SQLConfig = {}) → LanguageSupport

SQL language support for the given SQL dialect, with keyword completion, and, if provided, schema-based completion as extra extensions.

interface SQLConfig

Options used to configure an SQL extension.

dialect ⁠?: SQLDialect

The dialect to use. Defaults to StandardSQL.

schema ⁠?: SQLNamespace

You can use this to define the schemas, tables, and their fields for autocompletion.

defaultTable ⁠?: string

When given, columns from the named table can be completed directly at the top level.

defaultSchema ⁠?: string

When given, tables prefixed with this schema name can be completed directly at the top level.

upperCaseKeywords ⁠?: boolean

When set to true, keyword completions will be upper-case.

keywordCompletion ⁠?: fn(label: string, type: string) → Completion

Can be used to customize the completions generated for keywords.

type SQLNamespace = Object<SQLNamespace> | {self: Completion, children: SQLNamespace} | readonly (string | Completion)[]

The type used to describe a level of the schema for completion. Can be an array of options (columns), an object mapping table or schema names to deeper levels, or a {self, children} object that assigns a completion option to use for its parent property, when the default option (its name as label and type "type") isn't suitable.

class SQLDialect

Represents an SQL dialect.

language : LRLanguage

The language for this dialect.

spec : SQLDialectSpec

The spec used to define this dialect.

extension : Extension

Returns the language for this dialect as an extension.

configureLanguage (options: ParserConfig, name⁠?: string) → SQLDialect

Reconfigure the parser used by this dialect. Returns a new dialect object.

static define (spec: SQLDialectSpec) → SQLDialect

Define a new dialect.

type SQLDialectSpec

Configuration for an SQL Dialect.

keywords ⁠?: string

A space-separated list of keywords for the dialect.

builtin ⁠?: string

A space-separated string of built-in identifiers for the dialect.

types ⁠?: string

A space-separated string of type names for the dialect.

backslashEscapes ⁠?: boolean

Controls whether regular strings allow backslash escapes.

hashComments ⁠?: boolean

Controls whether # creates a line comment.

slashComments ⁠?: boolean

Controls whether // creates a line comment.

spaceAfterDashes ⁠?: boolean

When enabled -- comments are only recognized when there's a space after the dashes.

doubleDollarQuotedStrings ⁠?: boolean

When enabled, things quoted with "$" are treated as strings, rather than identifiers.

doubleQuotedStrings ⁠?: boolean

When enabled, things quoted with double quotes are treated as strings, rather than identifiers.

charSetCasts ⁠?: boolean

Enables strings like _utf8'str' or N'str'.

plsqlQuotingMechanism ⁠?: boolean

Enables string quoting syntax like q'[str]', as used in PL/SQL.

operatorChars ⁠?: string

The set of characters that make up operators. Defaults to "*+\-%<>!=&|~^/".

specialVar ⁠?: string

The set of characters that start a special variable name. Defaults to "?".

identifierQuotes ⁠?: string

The characters that can be used to quote identifiers. Defaults to "\"". Add [ for MSSQL-style bracket quoted identifiers.

caseInsensitiveIdentifiers ⁠?: boolean

Controls whether identifiers are case-insensitive. Identifiers with upper-case letters are quoted when set to false (which is the default).

unquotedBitLiterals ⁠?: boolean

Controls whether bit values can be defined as 0b1010. Defaults to false.

treatBitsAsBytes ⁠?: boolean

Controls whether bit values can contain other characters than 0 and 1. Defaults to false.

StandardSQL : SQLDialect

The standard SQL dialect.

PostgreSQL : SQLDialect

Dialect for PostgreSQL.

MySQL : SQLDialect

MySQL dialect.

MariaSQL : SQLDialect

Variant of MySQL for MariaDB.

MSSQL : SQLDialect

SQL dialect for Microsoft SQL Server.

SQLite : SQLDialect

SQLite dialect.

Cassandra : SQLDialect

Dialect for Cassandra's SQL-ish query language.

PLSQL : SQLDialect

PL/SQL dialect.

keywordCompletionSource (dialect: SQLDialect, upperCase⁠?: boolean = false, build⁠?: fn(label: string, type: string) → Completion) → CompletionSource

Returns a completion source that provides keyword completion for the given SQL dialect.

schemaCompletionSource (config: SQLConfig) → CompletionSource

Returns a completion sources that provides schema-based completion for the given configuration.
