代码演示
打开数据库
js
import { openDatabase, DatabaseOptions } from '@/uni_modules/lime-sqlite'
openDatabase({
name: 'text', // 支持路径,例如 '/static/db/test.db', 鸿蒙暂时没有条件处理。web暂不支持路径
success(res) {
console.log('openDatabase', res)
},
fail(err) {
console.log('openDatabase', err)
}
} as DatabaseOptions)
判断数据库是否打开
js
import { isOpenDatabase, DatabaseOptions } from '@/uni_modules/lime-sqlite'
isOpenDatabase({
name: 'text',
success(res) {
console.log('isOpenDatabase', res)
},
fail(err) {
console.log('isOpenDatabase', err)
}
} as DatabaseOptions)
关闭数据库
js
import { closeDatabase, DatabaseOptions } from '@/uni_modules/lime-sqlite'
closeDatabase({
name: 'text',
success(res) {
console.log('closeDatabase', res)
},
fail(err) {
console.log('closeDatabase', err)
}
} as DatabaseOptions)
执行事务
js
import { transaction, SqlTransactionOptions } from '@/uni_modules/lime-sqlite'
transaction({
name: 'text',
operation: 'begin',
success(res) {
console.log('transaction', res)
},
fail(err) {
console.log('transaction', err)
}
} as SqlTransactionOptions)
执行增删改等操作的SQL语句
js
import { executeSql, SqlOperationOptions } from '@/uni_modules/lime-sqlite'
executeSql({
name: 'text',
sql: [
"CREATE TABLE IF NOT EXISTS test (id INTEGER PRIMARY KEY AUTOINCREMENT, name TEXT NOT NULL, age INTEGER)",
"INSERT INTO test (name, age) VALUES ('Alice', 30)",
"INSERT INTO test (name, age) VALUES ('Bob', 25)",
"INSERT INTO test (name, age) VALUES ('Charlie', 35)"
],
success(res) {
console.log('executeSql', res)
},
fail(err) {
console.log('executeSql', err)
}
} as SqlOperationOptions)
执行查询的SQL语句
js
import { selectSql, SqlOperationOptions } from '@/uni_modules/lime-sqlite'
selectSql({
name: 'text',
sql: ['select * from test'],
success(res) {
console.log('selectSql', res)
},
fail(err) {
console.log('selectSql', err)
}
} as SqlOperationOptions)
WEB 使用
web下使用需要安装sql.js
,在终端输入
