Warning
This package is deprecated and, most probably, no longer functioning due to changes in packages it depends on. Please use simple-sql-query-builder instead.
An SQL query builder for RN projects. It executes built queries if an executing function is set.
Usage
SqlBuilder
This is the "entry point" of the builder. It contains only static
methods and fields.
import SqlBuilder from "react-native-sql-query-builder";
Turns on or off the debug mode. In debug mode each executed sql statement is logged to the console. SqlBuilder.setDebug(debug);
Sets a function to be used to execute sql statements. import SQLite from "react-native-sqlite-storage"; ... const db = await SQLite.openDatabase(...); SqlBuilder.setSqlExecutor(db.executeSql.bind(db));
Executes an sql statement by invoking a function set by `setSqlExecutor()`. It returns the result of that function invocation or simply the passed sql statement if `setSqlExecutor` hasn't been called. The result of invoking this method is returned from the CRUD methods. SqlBuilder.executeSql("some sql code);
Creates a table using [TableBuilder](#tableBuilder). const name = "weights"; const callback = tableBuilder => { tb.integer("rowid").primary(); tb.integer("millis").notNull(); tb.integer("gross").notNull(); tb.integer("net").notNull(); tb.text("comment").notNull(); }; const ifNotExists = Boolean; // Adds "IF NOT EXISTS" if true. Default: true. SqlBuilder.createTable(name, callback, ifNotExists);
TableBuilder
column()
Creates a [Column](#column) and returns it to allow method chaining. tb .column( name: "rate", type: "REAL") .notNull(); There are shorthands for the `INTEGER`, `TEXT` and `BLOB` types: tb.integer("rowid").primary(); tb.text("comment").notNull(); tb.blob("image");
unique()
Makes a column unique using [UniqueBuilder](#uniqueBuilder). tb.unique(ub => { ub .column("name") .collate("NOCASE") .order("ASC"); ub .column("code") .collate("NOCASE") .order("ASC"); });
Column
primary()
Adds `PRIMARY KEY` to this column definition.
foreign()
Adds `REFERENCES tableName(columnName)` to this column definition. tb.integer("type").foreign("tableName", "columnName");
onDelete()
Adds `ON DELETE action` to this column definition. tb.integer("journeyRowid") .foreign("tableName", "column name") .onDelete("action");
notNull()
Adds `NOT NULL` to this column definition.
UniqueBuilder
column()
Specifies the unique column name and optionally collation and order. ub .column("code") .collate("NOCASE") .order("ASC");
