+# 在**小项目中**推荐使用的**数据库表**实现方案
+
+
+## 简介
+在小型项目中，我们常常需要编写数据库的表结构，并需要在开发中不断地参考、维护该结构。
+
+在 EasySQL 中，我们提供了一个简单快捷的数据库表创建工具 `TableCreateBuilder` 。
+基于该工具，又在后续版本中提供了 `SQLTable` 类用于快速针对指定表创建不同的数据库操作。
+
+_SQLTable同时提供了有SQLManager参数与无参的操作方法，其中无参方法将自动调用初始化时使用的SQLManager进行操作。_
+
+以下内容是我在许多项目中的使用方法，由于其 `便捷`、`易于管理` 且 `支持引用查询` ，我十分推荐您参考我的方案，并应用到自己的项目中。
+
+### 实例项目: 
+- [QuickShop-Hikari (DataTables)](https://github.com/Ghost-chu/QuickShop-Hikari/blob/hikari/quickshop-bukkit/src/main/java/com/ghostchu/quickshop/database/DataTables.java)
+
+## 利用 NamedSQLTable 快速创建枚举类以管理
+
+这种方案的优势在于无需复制大量代码，仅需使用EasySQL已经提供的 `NamedSQLTable` 类快捷进行数据库操作。
+
+首先，我们需要创建一个枚举类，[示例代码](../demo/src/main/java/DataTables1.java)如下所示：
+
+```java
+import enums.cc.carm.lib.easysql.api.IndexType;
+import enums.cc.carm.lib.easysql.api.NumberType;
+import table.cc.carm.lib.easysql.api.NamedSQLTable;
+import org.jetbrains.annotations.NotNull;
+import org.jetbrains.annotations.Nullable;
+
+import java.sql.SQLException;
+
+public enum DataTables {
+
+    DATA(SQLTable.of("data", (table) -> {
+        table.addAutoIncrementColumn("id", true);
+        table.addColumn("user", "INT UNSIGNED NOT NULL");
+        table.addColumn("content", "TEXT NOT NULL");
+        table.addColumn("time", "DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP");
+    })),
+
+    USER(SQLTable.of("user", (table) -> {
+        table.addAutoIncrementColumn("id", NumberType.INT, true, true);
+        table.addColumn("uuid", "VARCHAR(32) NOT NULL UNIQUE KEY");
+        table.addColumn("username", "VARCHAR(16) NOT NULL");
+        table.addColumn("age", "TINYINT NOT NULL DEFAULT 1");
+        table.addColumn("email", "VARCHAR(32)");
+        table.addColumn("phone", "VARCHAR(16)");
+        table.addColumn("registerTime", "DATETIME NOT NULL");
+        table.setIndex("username", IndexType.UNIQUE_KEY); // 添加唯一索引
+        table.setIndex(IndexType.INDEX, "contact", "email", "phone"); //添加联合索引 (示例)
+    }));
+
+    private final NamedSQLTable table;
+
+    DataTables(NamedSQLTable table) {
+        this.table = table;
+    }
+
+    public NamedSQLTable get() {
+        return this.table;
+    }
+
+    public static void initialize(@NotNull SQLManager manager, @Nullable String tablePrefix) {
+        for (DataTables value : values()) {
+            try {
+                value.get().create(manager, tablePrefix);
+            } catch (SQLException e) {
+                // 提示异常
+            }
+        }
+    }
+
+}
+```
+
+随后，我们便可以在数据库初始化时调用 `DataTables#initialize(manager,tablePrefix)` 方法快捷的进行表的初始化。
+
+初始化后，我们便可以通过 `DataTables#get()` 方法获取对应表的 `NamedSQLTable` 实例，以进行 `createQuery()` 等操作。
+
+## 利用枚举类实现 SQLTable 进行操作
+
+这种方法相较于前者代码量稍多些，但无需在每次调用先通过 `DataTables#get()` 方法获取 NamedSQLTable 实例，代码上更为简洁。
+
+且可以通过重写 `getTableName()` 方法来自行规定表前缀。
+
+_该方法为本人最常用，也是最推荐的方法。_
+
+[示例代码](../demo/src/main/java/DataTables2.java)如下：
+
+```java
+import builder.cc.carm.lib.easysql.api.TableCreateBuilder;
+import enums.cc.carm.lib.easysql.api.IndexType;
+import enums.cc.carm.lib.easysql.api.NumberType;
+import org.jetbrains.annotations.NotNull;
+import org.jetbrains.annotations.Nullable;
+
+import java.sql.SQLException;
+import java.util.function.Consumer;
+
+public enum DataTables implements SQLTable {
+
+    USER((table) -> {
+        table.addAutoIncrementColumn("id", NumberType.INT, true, true);
+        table.addColumn("uuid", "VARCHAR(32) NOT NULL UNIQUE KEY");
+        table.addColumn("username", "VARCHAR(16) NOT NULL");
+        table.addColumn("age", "TINYINT NOT NULL DEFAULT 1");
+        table.addColumn("email", "VARCHAR(32)");
+        table.addColumn("phone", "VARCHAR(16)");
+        table.addColumn("registerTime", "DATETIME NOT NULL");
+        table.setIndex("username", IndexType.UNIQUE_KEY); // 添加唯一索引
+        table.setIndex(IndexType.INDEX, "contact", "email", "phone"); //添加联合索引 (示例)
+    });
+
+    private final Consumer<TableCreateBuilder> builder;
+    private @Nullable String tablePrefix;
+    private @Nullable SQLManager manager;
+
+    DataTables(Consumer<TableCreateBuilder> builder) {
+        this.builder = builder;
+    }
+
+    @Override
+    public @Nullable SQLManager getSQLManager() {
+        return this.manager;
+    }
+
+    @Override
+    public @NotNull String getTableName() {
+        // 这里直接选择用枚举的名称作为table的主名称
+        return (tablePrefix != null ? tablePrefix : "") + name().toLowerCase();
+    }
+
+    @Override
+    public boolean create(SQLManager sqlManager) throws SQLException {
+        return create(sqlManager, null);
+    }
+
+    public boolean create(@NotNull SQLManager sqlManager, @Nullable String tablePrefix) throws SQLException {
+        if (this.manager == null) this.manager = sqlManager;
+        this.tablePrefix = tablePrefix;
+
+        TableCreateBuilder tableBuilder = sqlManager.createTable(getTableName());
+        if (builder != null) builder.accept(tableBuilder);
+        return tableBuilder.build().executeFunction(l -> l > 0, false);
+    }
+
+    public static void initialize(@NotNull SQLManager manager, @Nullable String tablePrefix) {
+        for (DataTables value : values()) {
+            try {
+                value.create(manager, tablePrefix);

+                // 提示异常
+            }
