使用<loadUpdateData>从CSV文件加载数据Postgres

我希望有一些建议。我正在使用CSV文件中的五条记录完成一个表的简单加载。当我打开桌子上，我得到了错误的下面：使用<loadUpdateData>从CSV文件加载数据Postgres

liquibase.exception.DatabaseException: org.postgresql.util.PSQLException: ERROR: zero-length delimited identifier at or near """"

这是CSV文件

这是我的变更用于加载数据

<changeSet id="6-loadData" author="liquibase" dbms="postgresql" > 
<preConditions onErrorMessage="Failed Pre Conditions for table" onFail="HALT"> 
     <and> 
     <tableExists schemaName="public" tableName="contact" /> 
     <sqlCheck expectedResult ="1">SELECT COUNT(*) contact</sqlCheck> 
     </and> 
</preConditions> 
<comment>Adding Data...</comment> 
    <loadUpdateData catalogName="pg_catalog" 
     encoding="UTF-8" 
     file="src/main/resources/data/contacts.csv" 
     primaryKey="contact_id" 
     quotchar="A String" 
     schemaName="public" 
     separator="," 
     tableName="contact"> 
     <column name="contact_id" type="int" /> 
     <column name="contact_name" type="varchar(45)"/> 
     <column name="email" type="varchar(45)" /> 
     <column name="address" type="varchar(45)" /> 
     <column name="telephone" type="varchar(45)" /> 
    </loadUpdateData>

这是我创建表的变更集：

<changeSet id="4 Create Table" author="liquibase" runAlways="true"> 
    <preConditions onErrorMessage="Failed Pre Conditions for table" onFail="MARK_RAN"> 
     <not><tableExists schemaName="public" tableName="contact"/> </not> 
    </preConditions> 
    <comment>Creating Table named: Contact...</comment> 
    <createTable tableName="contact" schemaName="public"> 
     <column name="contact_id" type="int" > 
     <constraints primaryKey="true" nullable="false"/> 
     </column> 
     <column name="contact_name" type="varchar(45)"> 
     <constraints nullable="false"/> 
     </column> 
     <column name="email" type="varchar(45)"> 
     <constraints nullable="false"/> 
     </column> 
     <column name="address" type="varchar(45)"> 
     <constraints nullable="false"/> 
     </column> 
     <column name="telephone" type="varchar(45)"> 
     <constraints nullable="false"/> 
     </column> 
    </createTable>

这里是我使用的主键序列（CONTACT_ID）

<changeSet id="2-Create Sequence" author="liquibase" runAlways="true"> 
    <preConditions onErrorMessage="Failed Pre Conditions for sequence" onFail="MARK_RAN"> 
     <not><sequenceExists schemaName="public" sequenceName="contactid_seq" /></not> 
    </preConditions> 
    <comment>Creating Sequence...</comment> 
    <createSequence sequenceName="contactid_seq" 
        incrementBy="1" 
        minValue="1" 
        maxValue="9223372036854775807" 
        startValue="1" 
        ordered="1" 
        schemaName="public"/>

这是我如何使用约束：

<changeSet id="5-Add Constraint" author="liquibase"> 
    <comment>Adding contactid_seq sequence to Contact table...</comment> 
    <addDefaultValue catalogName="pg_catalog" 
     columnDataType="int" 
     columnName="contact_id" 
     tableName="contact" 
     schemaName="public" 
     defaultValueSequenceNext="contactid_seq" />

感谢您花时间阅读我的文章。
