proc中使用结构指针,编译出错?

zszhx

请教各位大哥姐:
我想将数据的结构定义在一个结构中,方便使用.但编译出错?为何?

typedef struct ckdmx_struct ckdmx_ptr;
EXEC SQL BEGIN DECLARE SECTION;
        EXEC SQL TYPE ckdmx_ptr IS VARRAW ;
        ckdmx_ptr *ckdmx_ptr1;
EXEC SQL END DECLARE SECTION;
performance_ptr1=(performance_ptr *)malloc(sizeof(performance_ptr));
ckdmx_ptr1=(ckdmx_ptr *)malloc(sizeof(ckdmx_ptr));


        memcpy(ckdmx_ptr1->ckdh,"XSCK-20051227-01-001",20);
        EXEC SQL INSERT INTO ckdmx VALUES(:ckdmx_ptr1->ckdh);
        EXEC SQL COMMIT WORK;

编译到:EXEC SQL INSERT INTO ckdmx VALUES(:ckdmx_ptr1->ckdh);
出错提示

Semantic error at line 172, column 37, file test3.pc:
        EXEC SQL INSERT INTO ckdmx VALUES(:ckdmx_ptr1->ckdh);
