== 概述
7+
8+
DBeaver Community 是跨平台图形化数据库客户端。IvorySQL 使用 PostgreSQL 传输协议，因此无需安装 IvorySQL 专用插件，使用 DBeaver 的 PostgreSQL 驱动即可连接。
9+
10+
本文在 Windows 11 上使用 DBeaver Community 26.2.0、PostgreSQL JDBC 42.7.13 和 IvorySQL 5.4（PostgreSQL 18.4）完成验证。通过 PostgreSQL 兼容端口实际测试了 Database Navigator 元数据会话、SQL 编辑器、DDL、DML、UTF-8 数据、事务回滚和执行计划；通过 Oracle 兼容端口测试了 Oracle 数据类型 DDL/DML、`dual` 和事务回滚。
11+
12+
== 创建 PostgreSQL 兼容连接
13+
14+
. 在 DBeaver 中选择 *数据库* > *新建数据库连接*。
15+
. 选择 *PostgreSQL* 数据库驱动。
16+
. 填写连接参数：
17+
18+
[cols="1,2"]
19+
|====
20+
|设置 |值
21+
22+
|主机
23+
|IvorySQL 服务器地址，例如 `127.0.0.1`
24+
25+
|端口
26+
|PostgreSQL 兼容端口，默认为 `5432`
27+
28+
|数据库
29+
|目标数据库，例如 `ivorysql`
30+
31+
|用户名
32+
|IvorySQL 登录角色
33+
34+
|密码
35+
|角色密码
36+
|====
37+
38+
. 如有提示，允许 DBeaver 下载 PostgreSQL JDBC 驱动。
39+
. 单击 *测试连接*，成功后单击 *完成*。
40+
41+
对应的 JDBC URL 为：
42+
43+
[source,text]
44+
----
45+
jdbc:postgresql://127.0.0.1:5432/ivorysql
46+
----
47+
48+
== 验证连接
49+
50+
打开该连接的 SQL 编辑器并执行：
51+
52+
[source,sql]
53+
----
54+
SELECT version();
55+
56+
CREATE TABLE dbeaver_validation (
57+
id integer PRIMARY KEY,
58+
label text NOT NULL
59+
);
60+
INSERT INTO dbeaver_validation VALUES (1, 'IvorySQL'), (2, '北京');
61+
SELECT * FROM dbeaver_validation ORDER BY id;
62+
63+
EXPLAIN SELECT * FROM dbeaver_validation WHERE id = 1;
64+
----
65+
66+
在 Database Navigator 中刷新 `public` schema，应能看到该表及其两列。使用 *数据* > *查看数据* 可浏览或编辑数据行。
67+
68+
如需验证事务控制，可关闭自动提交、插入一行后单击 *回滚*，并确认该行不存在。
69+
70+
== 连接 Oracle 兼容端口
71+
72+
使用相同的 PostgreSQL 驱动和数据库参数创建第二个连接，但将端口改为 IvorySQL Oracle 兼容端口（默认为 `1521`）。该连接仍使用 PostgreSQL JDBC 协议，不同端口用于选择 IvorySQL Oracle 兼容 SQL 模式。
73+
74+
[source,text]
75+
----
76+
jdbc:postgresql://127.0.0.1:1521/ivorysql
77+
----
78+
79+
在 SQL 编辑器中验证 Oracle 兼容语法：
80+
81+
[source,sql]
82+
----
83+
SELECT 1 FROM dual;
84+
85+
CREATE TABLE dbeaver_ora_validation (
86+
id NUMBER PRIMARY KEY,
87+
label VARCHAR2(40)
88+
);
89+
INSERT INTO dbeaver_ora_validation VALUES (1, 'IvorySQL');
90+
SELECT * FROM dbeaver_ora_validation;
91+
DROP TABLE dbeaver_ora_validation;
92+
----
93+
94+
也可以使用 PostgreSQL 兼容连接，只切换当前会话：
95+
96+
[source,sql]
97+
----
98+
SET ivorysql.compatible_mode=oracle;
99+
SELECT 1 FROM dual;
100+
----
101+
102+
== 注意事项与限制
103+
104+
* DBeaver 会将 IvorySQL 识别为 PostgreSQL，可使用 PostgreSQL 导航、元数据、数据编辑和执行计划功能，但不提供面向 Oracle 数据库的专用管理面板。
105+
* `SET ivorysql.compatible_mode` 只影响当前数据库会话。DBeaver 会建立额外的元数据和编辑器会话，因此使用独立的 Oracle 端口连接可避免各会话模式不一致。
106+
* 使用带双引号的 Oracle 兼容标识符时应保留大小写；两种兼容模式对未加引号标识符的大小写折叠规则不同。
107+
* 不要在共享工作站保存生产密码；应使用 TLS 和部署环境要求的认证方式。
108+
* 对生产连接可启用 DBeaver 的只读和 SQL 执行限制，降低误操作风险。
109+
110+

== Overview
7+
8+
DBeaver Community is a cross-platform graphical database client. IvorySQL uses the PostgreSQL wire protocol, so DBeaver can connect with its PostgreSQL driver without an IvorySQL-specific plugin.
9+
10+
This guide was validated on Windows 11 with DBeaver Community 26.2.0, PostgreSQL JDBC 42.7.13, and IvorySQL 5.4 (PostgreSQL 18.4). Database Navigator metadata sessions, the SQL editor, DDL, DML, UTF-8 data, transaction rollback, and execution plans were tested through the PostgreSQL-compatible port. Oracle-compatible DDL, DML, `dual`, and transaction rollback were also tested through the Oracle-compatible port.
11+
12+
== Create a PostgreSQL-compatible connection
13+
14+
. In DBeaver, select *Database* > *New Database Connection*.
15+
. Select *PostgreSQL* as the database driver.
16+
. Enter the connection settings:
17+
18+
[cols="1,2"]
19+
|====
20+
|Setting |Value
21+
22+
|Host
23+
|IvorySQL server address, for example `127.0.0.1`
24+
25+
|Port
26+
|The PostgreSQL-compatible port, `5432` by default
27+
28+
|Database
29+
|Target database, for example `ivorysql`
30+
31+

32+
|An IvorySQL login role
33+
34+
|Password
35+
|The role password
36+
|====
37+
38+
. If prompted, allow DBeaver to download the PostgreSQL JDBC driver.
39+
. Select *Test Connection*, then *Finish*.
40+
41+
The equivalent JDBC URL is:
42+
43+
[source,text]
44+
----
45+
jdbc:postgresql://127.0.0.1:5432/ivorysql
46+
----
47+
48+
== Validate the connection
49+
50+
Open an SQL editor for the connection and run:
51+
52+
[source,sql]
53+
----
54+
SELECT version();
55+
56+
CREATE TABLE dbeaver_validation (
57+
id integer PRIMARY KEY,
58+
label text NOT NULL
59+
);
60+
INSERT INTO dbeaver_validation VALUES (1, 'IvorySQL'), (2, '北京');
61+
SELECT * FROM dbeaver_validation ORDER BY id;
62+
63+
EXPLAIN SELECT * FROM dbeaver_validation WHERE id = 1;
64+
----
65+
66+
Refresh the `public` schema in Database Navigator. The table and its two columns should appear. Use *Data* > *View Data* to inspect or edit rows.
67+
68+
To verify transaction control, disable auto-commit, insert a row, select *Rollback*, and confirm that the row is absent.
69+
70+
== Connect to the Oracle-compatible port
71+
72+
Create a second connection with the same PostgreSQL driver and database settings, but use the IvorySQL Oracle-compatible port (`1521` by default). This remains a PostgreSQL JDBC connection; the different port selects IvorySQL's Oracle-compatible SQL mode.
73+
74+
[source,text]
75+
----
76+
jdbc:postgresql://127.0.0.1:1521/ivorysql
77+
----
78+
79+
Validate Oracle-compatible syntax in the SQL editor:
80+
81+
[source,sql]
82+
----
83+
SELECT 1 FROM dual;
84+
85+
CREATE TABLE dbeaver_ora_validation (
86+
id NUMBER PRIMARY KEY,
87+
label VARCHAR2(40)
88+
);
89+
INSERT INTO dbeaver_ora_validation VALUES (1, 'IvorySQL');
90+
SELECT * FROM dbeaver_ora_validation;
91+
DROP TABLE dbeaver_ora_validation;
92+
----
93+
94+
Alternatively, use the PostgreSQL-compatible connection and switch only the current session:
95+
96+
[source,sql]
97+
----
98+
SET ivorysql.compatible_mode=oracle;
99+
SELECT 1 FROM dual;
100+
----
101+
102+
== Notes and limitations
103+
104+
* DBeaver identifies IvorySQL as PostgreSQL. PostgreSQL navigation, metadata, editing, and plan features are available; Oracle-specific DBeaver administration panels are not expected.
105+
* A `SET ivorysql.compatible_mode` command applies only to its current database session. A dedicated Oracle-port connection avoids mode changes when DBeaver opens additional metadata or editor sessions.
106+
* Preserve the case of quoted Oracle-compatible identifiers. Unquoted identifier folding differs between compatibility modes.
107+
* Do not save production passwords on shared workstations. Prefer TLS and the authentication method required by your deployment.
108+
* For production connections, consider enabling DBeaver's read-only and SQL execution restrictions to reduce accidental changes.
109+
110+
