从postgresql函数参数中检索php数组键和值以进行数据库更新

我试图将一组键值对发送到postgresql函数作为参数.阵列的结构如下 –

array(10) {   ["OWNER"]=> string(3) "ERP"   ["SOURCE"]=> string(7) "Unknown"   ["PRIORITY"]=> string(6) "Medium"   ["PREFLOC"]=> string(5) "Dhaka"   ["PROBABLE"]=> string(2) "50"   ["MAXSIZE"]=> string(4) "1000"   ["MINSIZE"]=> string(4) "2000"   ["INTAREA"]=> string(14) "Dhaka, Gulshan"   ["CVALPRF"]=> string(5) "Great"   ["OPPAMOUNT"]=> string(3) "200" }

函数接受这样的字符串数组参数

CREATE OR REPLACE FUNCTION document.update_doc_attrib_on_opportunity(p_org_id numeric, p_target_doc_code character varying, p_target_doc_no numeric, p_doc_attribs character varying[])

现在我想把数组发送到我的函数中的p_doc_attribs.对于特定的键名,我需要在表中插入所需的值.
以下查询需要相应更新 –

'UPDATE use_doc_attribute        SET attrib_value = CASE WHEN attrib_code = ''PREFLOC''  THEN ''' || p_preferred_location || '''                    WHEN attrib_code = ''PRIORITY'' THEN ''' || p_priority || '''                    WHEN attrib_code = ''PROBABLE'' THEN ''' || p_probability || '''                    WHEN attrib_code = ''SOURCE''   THEN ''' || p_source || '''                    WHEN attrib_code = ''MAXSIZE''  THEN ''' || p_max_size || '''                    WHEN attrib_code = ''MINSIZE''  THEN ''' || p_min_size || '''                    WHEN attrib_code = ''INTAREA''  THEN ''' || p_interested_areas || '''                    WHEN attrib_code = ''CVALPRF''  THEN ''' || p_client_value_profile || '''                    ELSE attrib_value                   END        WHERE org_id = ' || p_org_id || '        AND document_no = ' || p_target_doc_no || '        AND document_code = ''' || p_target_doc_code || '''';

attrib_code将包含密钥,特定情况的attrib_value将是从p_doc_attribs数组中检索的值.

解决方法:

我不是这方面的专家,但您可以对数组进行json_encode并将其传递给您的函数,因为您必须对您的函数进行以下更改：

CREATE OR REPLACE FUNCTION document.update_doc_attrib_on_opportunity(    p_org_id numeric,     p_target_doc_code character varying,     p_target_doc_no numeric,     p_doc_attribs JSON)

你的查询可能是这样的：

'UPDATE use_doc_attribute    SET attrib_value = CASE WHEN attrib_code = ''PREFLOC''  THEN ''' || p_doc_attribs['PREFLOC'] || '''                WHEN attrib_code = ''PRIORITY'' THEN ''' || p_doc_attribs['PRIORITY'] || '''                WHEN attrib_code = ''PROBABLE'' THEN ''' || p_doc_attribs['PROBABLE'] || '''                WHEN attrib_code = ''SOURCE''   THEN ''' || p_doc_attribs['SOURCE'] || '''                WHEN attrib_code = ''MAXSIZE''  THEN ''' || p_doc_attribs['MAXSIZE'] || '''                WHEN attrib_code = ''MINSIZE''  THEN ''' || p_doc_attribs['MINSIZE'] || '''                WHEN attrib_code = ''INTAREA''  THEN ''' || p_doc_attribs['INTAREA']|| '''                WHEN attrib_code = ''CVALPRF''  THEN ''' || p_doc_attribs['CVALPRF'] || '''                ELSE attrib_value               END    WHERE org_id = ' || p_org_id || '    AND document_no = ' || p_target_doc_no || '    AND document_code = ''' || p_target_doc_code || '''';

您可以查看以下link以获取更多此类示例.

编辑

我认为为此工作你需要安装PLV8扩展,你可以找到更多信息here

编辑V 9.1.x.

您可以创建并传递索引数组,例如,create array类似于以下内容：

[    "ERP",    "Unknown",    "Medium",    "Dhaka",    "50",    "1000",    "2000",    "Dhaka, Gulshan",    "Great",    "200"]

然后使用PHP array to postgres array函数转换并将该数组传递给postgresql函数,并将查询中使用的数组值更改为基于索引而不是基于键,如下所示：

p_doc_attribs [3]

代替

p_doc_attribs [ ‘PREFLOC’]
