Caused by: org.postgresql.util.PSQLException: ERROR: column "imagesync__c" is of type boolean but expression is of type character varying

Question

我正在使用 WSO2 Report Mediator 将记录插入到 postgreSql Table。面临的问题如 column "imagesync__c" 是 boolean 类型，但表达式是 character varying

类型

仅供参考，

列“imagesync__c”的数据类型是 bool 并使用 DBeaver 6.1.2

<property name="syncFlag" scope="default" type="BOOLEAN" value="true"/>
<dbreport description="Insert into product2">
            <connection>
                <pool>
                    <dsName>jdbc/QRSagAppSyncDataSource</dsName>
                </pool>
            </connection>
            <statement>
                <sql><![CDATA[INSERT INTO vonbibra_dev.product2(productcode,db_lastmodifiedbyuser,imagesync__c,sourcename__c)VALUES(?, ?,?,?,?)]]></sql>
                <parameter type="VARCHAR" value="CarSales"/>
                <parameter type="VARCHAR" value="qrsintegration"/>
                **<parameter type="VARCHAR" expression="get-property('syncFlag')"/>**
                <parameter type="VARCHAR" value="CarSales"/>
            </statement>
  </dbreport>

我尝试了下面针对该特定专栏提到的一些转换，不幸的是，其中 none 有效。

铸造方式

<parameter value="select get-property('syncFlag')::boolean" type="VARCHAR"/>
<parameter value="CAST(get-property('syncFlag') as BOOLEAN)" type="VARCHAR"/>
<parameter type="VARCHAR" value="1"/>
<parameter type="VARCHAR" value="SELECT DECODE(get-property('syncFlag'), 'false', '0', 'true', '1' )::BOOLEAN"/>

我已经通过 CASTING 在 sql 查询而不是输入参数 .

中解决了我的问题

<property name="syncFlag" scope="default" type="BOOLEAN" value="true"/>
<dbreport description="Insert into product2">
            <connection>
                <pool>
                    <dsName>jdbc/QRSagAppSyncDataSource</dsName>
                </pool>
            </connection>
            <statement>
                <sql><![CDATA[INSERT INTO vonbibra_dev.product2(productcode,db_lastmodifiedbyuser,imagesync__c,sourcename__c)VALUES(?, ?,?,?::BOOLEAN,?)]]></sql>
                <parameter type="VARCHAR" value="CarSales"/>
                <parameter type="VARCHAR" value="qrsintegration"/>
                **<parameter type="VARCHAR" expression="get-property('syncFlag')"/>**
                <parameter type="VARCHAR" value="CarSales"/>
            </statement>
  </dbreport>
