+ Db Messiah scans user provided data classes and all their properties with reflection
+ in order to know how to decode user actions like `db.table.create()`
+ into prepared SQL statements that are type safe, escaped, and free from SQL injections. +

+ +

+ Because everything is scanned with reflection,
+ your data classes will directly represent your whole database structure,
+ without the need of developer interference or any additional work.
+ Here is an minimalistic example how would you define database with one table... +

+ +```kotlin +data class TestTable(var id: Int? = null, val column: String) + +val db = SqliteService( + config = Properties().apply { this["jdbcUrl"] = "jdbc:sqlite::memory:" }, + ser = SqliteSerializer( + tables = listOf(Table(TestTable::id)), + globalSerializers = BasicTS.sqlite + ) +) + +db.autocommit { + val row = TestTable(column = "col0") + it.table.drop() + it.table.create() + it.table.delete() + it.row.insert(row) + assert(row.id != null) + assert(it.row.select(pk = 1)!! == row) + assert(it.table.select() == listOf(row)) + it.table.delete() +} +``` + +Because of that, it provides very simple solution for writing complex queries.
+There are only 4 methods to be remembered: it.name, it.column, it.table, it.input
+Thats it! Everything else is joust ordinary SQL syntax that you know and love.
+This is an example how the most complex query in db-messiah looks like, +it's basically raw SQL with additional features like type safety and SQL injection . +

+ +```kotlin +val result = it.query.get(output = Out::class, input = parent) { + """ + SELECT ${it.column(Child::value)} AS ${it.name(Out::child_value)}, + ${it.column(Parent::value)} AS ${it.name(Out::parent_value)} + FROM ${it.table()} + JOIN ${it.table()} ON ${it.column(Parent::pk)} = ${it.column(Child::parent_pk)} + WHERE ${it.column(Child::value)} = ${it.input(Parent::value)} + """ +} +``` +
