Question

我正在解决阻止我的存储过程停止工作的错误：

“您的SQL语法中有错误;请查看与您的MySQL服务器版本对应的手册，以便在'IF（SELECTED_PROJECT_LOBSELECTION ='复制整个项目'）附近使用正确的语法。然后在第1行设置高亮显示： “

以下是我的IF / ELSEIF声明的一部分：

    IF (SELECTED_PROJECT_LOBSELECTION = 'Copy the Whole Project') THEN
  SET lobInsertStmt = ' AND p.PROJECTION_PROJECT_NME = ' || SELECTED_PROJECT_NAME
                   || ' AND p.PROJECTION_PROJ_CATG_NME = ' || SELECTED_PROJECT_CATG
                   || ' AND p.FINANCIAL_PROJECTION_YEAR_NUM = ' || CAST(SELECTED_PROJECT_YEAR AS int)
                   || ' AND g.MODEL_GROUP_SNAPSHOT_TSP = ' || SELECTED_SNAPSHOT_TIMESTAMP;

我做错了什么，为什么我的比较不起作用？谢谢！

更新我的问题不是IF / THEN比较。这是IN params的阅读方式。以下是解决方案：

IF (SELECTED_PROJECT_LOBSELECTION = 'Copy the Whole Project') THEN
  SET lobInsertStmt = ' AND p.PROJECTION_PROJECT_NME = ''' || SELECTED_PROJECT_NAME || ''''
                   || ' AND p.PROJECTION_PROJ_CATG_NME = ''' || SELECTED_PROJECT_CATG || ''''
                   || ' AND p.FINANCIAL_PROJECTION_YEAR_NUM = ' || TRIM(CAST(SELECTED_PROJECT_YEAR AS int))
                   || ' AND g.MODEL_GROUP_SNAPSHOT_TSP = ''' || SELECTED_SNAPSHOT_TIMESTAMP || '''';

现在，我收到的SQLSTATE为07005，它是：“无法按指定使用游标'cursor-name'，因为在游标声明中指定的预准备语句不是SELECT语句。”

如何在没有光标的情况下使用存储过程进行插入？

以下是其他代码：

我回答了我的问题。我删除了游标并添加了一个执行语句

EXECUTE PREPSTMT;

准备之后

SQL插入使用存储过程
