`typescript
import { MySQLAnalyzer } from 'ts-mysql-analyzer'
import { MySQLSchema } from 'ts-mysql-schema'
const mySQLSchema = new MySQLSchema({
uri: 'mysql://root@127.0.0.1:3310/test'
})
const analyzer = new MySQLAnalyzer({
schema: await mySQLSchema.getSchema()
})
// "'SELT' is not valid at this position."
console.log(analyzer.analyze('SELT * FROM user'))
// "Table 'invalid_table' does not exist in database 'test'. Did you mean 'posts'?"
console.log(analyzer.analyze('SELECT * FROM invalid_table'))
// "Column 'invalid_column' does not exist in table 'users'. Did you mean 'name'?"
console.log(analyzer.analyze('SELECT invalid_column FROM users'))
// "Type boolean is not assignable to type string."
console.log(analyzer.analyze('SELECT * FROM users WHERE id = true'))
// "You can optimize this query by adding a MySQL index for column 'name'."
console.log(analyzer.analyze('SELECT * FROM users WHERE name = "some-name"'))
