我想使用 sql 命令从缓存中读取。由于 sql 命令每次都是动态的,我需要将其作为变量输入,但不支持在 sql 命令中使用变量。这是我的代码:
import com.typesafe.config.{Config, ConfigFactory}
import com.zaxxer.hikari.{HikariConfig, HikariDataSource}
import javax.sql.DataSource
import scalikejdbc._
//load config from application.conf
lazy val config: Config = ConfigFactory.load("application.conf")
val md: DataSource = {
val hikariConfig = new HikariConfig()
hikariConfig.setJdbcUrl(config.getString("jdbc.ignite.url"))
hikariConfig.setUsername(config.getString("jdbc.ignite.username"))
hikariConfig.setPassword(config.getString("jdbc.ignite.password"))
hikariConfig.setDriverClassName(config.getString("jdbc.ignite.driver"))
val ds = new HikariDataSource(hikariConfig)
ds
}
ConnectionPool.singleton(new
DataSourceConnectionPool(inMemoryDataSource))
val inMemoryDbName: String = config.getString("jdbc.ignite.name")
ConnectionPool.add(inMemoryDbName, new
DataSourceConnectionPool(inMemoryDataSource))
lazy val inMemorySession: DBSession = AutoSession
lazy val inMemoryDatabaseExecutorContext: ExecutionContext =
ExecutionContext.fromExecutorService(Executors.newFixedThreadPool(1))
def getAggResult(query: String) = DB readOnly {
implicit session =>
sql"$query".map(_.toMap()).list().apply()
}
问题是我使用的'$',错误说:
java.sql.SQLException: Failed to parse query. Syntax error in SQL
statement "?[*]"; expected "[, ::, ="; SQL statement:
这query
是一个选择命令,如select field1, field2 from table name where condition1 like value1
如何解决?
