import com.powersync.db.schema.Schema
import com.powersync.db.schema.Table

val schema = Schema(
  Table(
    name = "assets1",
    columns = listOf(
        Column.text("name"),
        Column.integer("count"),
        Column.text("owner_id")
    )

    name = "assets2",
    columns = listOf(
        Column.text("name"),
        Column.integer("count"),
        Column.text("other_id"),
        Column.text("foo")
    )
  )
)

Swift

import PowerSync

let schema = Schema(
  Table(
    name: "assets1",
    columns: [
        .text("name"), // text
        .integer("count"), // int4
        .text("owner_id") // uuid
    ]

  Table(
    name: "assets2",
    columns: [
        .text("name"), // text
        .integer("count"), // int4
        .text("other_id"), // uuid
        .text("foo")
    ]

.Net

using PowerSync.Common.DB.Schema;

class AppSchema
{
  public static Table Assets1 = new Table(new Dictionary<string, ColumnType>
  {
      { "name", ColumnType.TEXT },
      { "count", ColumnType.INTEGER },
      { "owner_id", ColumnType.TEXT }
  });

  public static Table Assets2 = new Table(new Dictionary<string, ColumnType>
  {
      { "name", ColumnType.TEXT },
      { "count", ColumnType.INTEGER },
      { "other_id", ColumnType.TEXT },
      { "foo", ColumnType.TEXT }
  });

  public static Schema PowerSyncSchema = new Schema(new Dictionary<string, Table>
  {
    {"assets1", Assets1},
    {"assets2", Assets2}

return `{ "${column.name}", ${cSharpColumnType(column)} }`;
