源代码：ZGLanguage 解析SQL数据血缘 之 显示 UNION SQL 结构图

SQL代码如下所示 :

CREATE TABLE TMP_TARGET_TABLE_1
AS
SELECT *
FROM NYBDP.O_SS_CL_LOAN_ACCT_STATIS CL

UNION ALL -----

SELECT *
FROM NYBDP.O_CWWS_ACCT_LOAN AL

UNION ALL -----

SELECT *
FROM NYBDP.O_CWWS_ACCT_NO
;

通过 ZGLanguage + Python 将以上SQL转换成 Echarts 的树结构数据：

[
    {
        "name": "file:out.zgl",
        "children": [
            {
                "name": "TMP_TARGET_TABLE_1",
                "children": [
                    {
                        "name": "O_SS_CL_LOAN_ACCT_STATIS",
                        "children": []
                    },
                    {
                        "name": "__UNION_SELECT__6__",
                        "children": [
                            {
                                "name": "O_CWWS_ACCT_LOAN",
                                "children": []
                            }
                        ]
                    },
                    {
                        "name": "__UNION_SELECT__11__",
                        "children": [
                            {
                                "name": "O_CWWS_ACCT_NO",
                                "children": []
                            }
                        ]
                    }
                ]
            }
        ]
    }
]
