■ 现象 DB2,Schema和访问DB的用户名不一致。 调用存储过程时必须指定Schema,否则Error。

DB2 不指定Schema调用存储过程失败 SQLCODE=-440, SQLSTATE=42884

■ 错误代码 存储过程

        SET SCHEMA = "QUOTATION";         SET CURRENT PATH = "SYSIBM","SYSFUN","SYSPROC","SYSIBMADM","DB2INST1";         CREATE PROCEDURE COPY_QUOTATION_TABLES (。。。。。。)         BEGIN                 。。。。。。         END;

        GRANT EXECUTE ON PROCEDURE "QUOTATION"."COPY_QUOTATION_TABLES"( VARCHAR(36), VARCHAR(36), INTEGER, TIMESTAMP, INTEGER, INTEGER ) TO USER "DB2INST1" WITH GRANT OPTION;

Mapper.xml

        <update id="copyQuotationTables" statementType="CALLABLE" parameterType="map">                 CALL COPY_QUOTATION_TABLES (                     #{quotationId, jdbcType=VARCHAR, mode=IN}                     , #{newQuotationId, jdbcType=VARCHAR, mode=IN}                     , #{userId, jdbcType=INTEGER, mode=IN}                     , #{currentTime, jdbcType=TIMESTAMP, mode=IN}                     , #{reasonTypeFlag, jdbcType=INTEGER, mode=IN}                     , #{copyReason, jdbcType=INTEGER, mode=IN} )         </update>

Mapper.java

        /**         * Copy Quotation Tables         *         * @param param the parameter         */         void copyQuotationTables(Map<String, Object> param);

Service.java

        Map<String, Object> paramMap = new HashMap<String, Object>();         paramMap.put("quotationId", quotationId);         paramMap.put("newQuotationId", newQuotationId);         paramMap.put("userId", userId);         paramMap.put("currentTime", currentTime);         paramMap.put("reasonTypeFlag", 1);         paramMap.put("copyReason", 1);         Mapper.copyQuotationTables(paramMap);

Tomcat context.xml

    <Resource name="jdbc/testDS" auth="Container" type="javax.sql.DataSource"               driverClassName="com.ibm.db2.jcc.DB2Driver"               url="jdbc:db2://127.0.0.1:50000/test:currentSchema=QUOTATION;"               username="db2inst1" password="db2inst1" maxActive="100"  maxIdle="30"/>

■ 正确代码 Tomcat context.xml中追加currentFunctionPath。

    <Resource name="jdbc/testDS" auth="Container" type="javax.sql.DataSource"               driverClassName="com.ibm.db2.jcc.DB2Driver"               url="jdbc:db2://127.0.0.1:50000/test:currentSchema=QUOTATION;currentFunctionPath=QUOTATION;"               username="db2inst1" password="db2inst1" maxActive="100"  maxIdle="30"/>

如果想在DB工具(如:Toda)中调用存储过程,但不指定Schema, 如:CALL COPY_QUOTATION_TABLES(。。。。。。) 需要在创建存储过程时,指定Current Path

SET CURRENT PATH = "SYSIBM","SYSFUN","SYSPROC","SYSIBMADM","DB2INST1","QUOTATION";

■ 原因 DB2存储过程(和函数)不受CURRENT SCHEMA控制,而是由CURRENT PATH控制。
