c++how中的开关断开故障

我正在尝试运行以下代码：

SQLSMALLINT** column_types = new SQLSMALLINT*[*ColumnCount];

void** ColumnsData = new void*[*ColumnCount];
SQLINTEGER** rowLengths = new SQLINTEGER*[*ColumnCount];
int limit = *ColumnCount;
for(int i=0;i<limit;i++)
{
    column_types[i] = new SQLSMALLINT();
     SQLColAttribute(hStmt,i+1,SQL_DESC_TYPE,NULL,NULL,NULL,(SQLPOINTER)column_types[i]);
     SQLSMALLINT type = *column_types[i];
     switch(type)
     {
     case SQL_CHAR:
             ColumnsData[i] = new SQLCHAR**[*RowCount];
             for(int l=0;l<*RowCount;l++)
             {

             }

当它进入案例SQL_CHAR并中断时，它会在SQLBindcol调用之前跳到案例SQL_TYPE_DATE，这怎么可能，是故障还是我在这里做错了什么，因为中断应该退出开关
